- 0:07- Hello and welcome
- 0:08to the Dementia Researcher Podcast.
- 0:11Today's episode is coming to you
- 0:12from ADPD Conference in Copenhagen,
- 0:15where researchers from around the world
- 0:17have gathered to share new findings
- 0:19on Alzheimer's disease, Parkinson's disease,
- 0:22and other related neurodegenerative conditions.
- 0:25(upbeat music)
- 0:31I'm Louise Serpell,
- 0:32a Professor of Biochemistry from
- 0:33the University of Sussex,
- 0:35and I'm delighted to be hosting today's show.
- 0:38This week, the ADPD Conference
- 0:40has brought together scientists
- 0:42working across the full spectrum
- 0:44of neurodegenerative research
- 0:47from molecular mechanisms
- 0:48to biomarkers and clinical trials.
- 0:51Across the few days,
- 0:52there have been hundreds of talks
- 0:53and posters, so rather than
- 0:55trying to summarise everything,
- 0:57today, we're going to focus on
- 0:58a few highlights that really
- 1:00stood out to our guests during the meeting.
- 1:02Joining me are three people
- 1:04who have been exploring this conference,
- 1:07Athina, Lauren and Sofie.
- 1:11And I'm going to ask them each to
- 1:12introduce themselves and tell you
- 1:14a little bit about their background.
- 1:16(upbeat music)
- 1:22Before we begin, could I ask each
- 1:24of you to briefly introduce yourselves
- 1:26and tell listeners what area of
- 1:28research or work you're involved in.
- 1:31Athina?
- 1:32- Hello, I'm Athina Grigoriou
- 1:34and I'm a second year PhD student
- 1:37in Dr. David Koss's lab at
- 1:39the University of Dundee in Scotland.
- 1:41So we are working on DNA damage,
- 1:43so basically understanding
- 1:45the role of DNA damage in dementia
- 1:46with the Lewy bodies
- 1:47and then compare it with
- 1:48other neurodegenerative diseases
- 1:50such as, Alzheimer's disease.
- 1:52And specifically, I'm looking
- 1:54into the role of alpha-synuclein
- 1:56in DNA damage repair pathways.
- 1:58And what comes first, basically.
- 2:00Yeah, that's me, thank you. - Thank you.
- 2:03And Lauren?
- 2:03- Okay, so hi, I am Lauren O'Neill.
- 2:05I'm also working at the University of Dundee
- 2:08alongside Athina in Dr. David Koss's lab.
- 2:12So my project is looking at elucidating
- 2:15the mechanisms or specifically,
- 2:17where alpha-synuclein is gonna
- 2:18bind on the human genome
- 2:19in dementia with Lewy bodies
- 2:22and my background in mitochondrial biology
- 2:26and also my interest in DNA damage.
- 2:28I kind of wanna, for my project
- 2:31ship them these two together to look
- 2:33at mitochondrial DNA damage specifically
- 2:35and see if there's alpha-synuclein
- 2:36you can also bind
- 2:37in the mitochondrial genome. - Oh, fantastic.
- 2:39Sounds really interesting.
- 2:40And lastly, but not least, Sofie.
- 2:42- Yeah, hi everyone, I am Sofie Frandsen
- 2:45and I am a senior research scientist
- 2:48at a small biotech company called, Vesper Bio,
- 2:52which is actually based here in Copenhagen.
- 2:53So this year's ADPD Conference
- 2:55is in my hometown, so that's very nice.
- 2:59So I am a pharmacist by training
- 3:01and have done a PhD
- 3:03focusing on Parkinson's disease.
- 3:06And right now, I am working at Vesper
- 3:08who are developing small molecules,
- 3:10a sortilin inhibitor to increase
- 3:13the important protein in the brain
- 3:16called, progranulin, which is
- 3:18decreased in a lot of
- 3:19neurodegenerative diseases such as,
- 3:21FTD, Parkinson's disease,
- 3:23and also in mood disorders.
- 3:25So yeah, very nice to be here. - All right,
- 3:27thank you very much, Sofie.
- 3:28So welcome everybody.
- 3:30So how have you found
- 3:31the conference so far, enjoyable?
- 3:34- Very. - Yes.
- 3:35- Brilliant. - A lot of talks,
- 3:36a lot of good posters.
- 3:38- Yeah, it is very big.
- 3:40I think it's one of the biggest
- 3:41conferences we've been to,
- 3:43but was talking for myself, yeah.
- 3:46- Well, just to give the listeners
- 3:47a bit of a flavour for it,
- 3:48it's, I think five or six parallel sessions.
- 3:53Hundreds and hundreds of posters,
- 3:55loads of exhibitors, it's a lot.
- 3:58It's a lot it to try and cover it all.
- 4:00- Yeah, I think there was over 700 posters
- 4:02per shift and there's two shifts,
- 4:04so there's a lot to go around, yeah.
- 4:06- So you have to pick carefully.
- 4:08- Yeah. - Don't you?
- 4:10- And the prior sessions were like,
- 4:12there's one in the morning,
- 4:13there's two in the afternoon,
- 4:15and I dunno, it was like eight talks
- 4:17per session, per prior session.
- 4:20- So I think the app helps a lot
- 4:23as well because then you can get
- 4:24an overview of which talks,
- 4:26you can highlight them as your favourites
- 4:28because otherwise, there's so many.
- 4:31- [Prof Louise] Yeah. - They had an AI summary
- 4:33as well, so you could go back
- 4:36and get a report of what the main findings
- 4:38of the research or each talk.
- 4:42That was really good.
- 4:42It was really helpful.
- 4:43- Yeah, yeah, that's good.
- 4:45So let's start with Athina.
- 4:49I would like to know
- 4:51what you found most interesting.
- 4:53I think you've picked out one
- 4:54particular topic you're particularly
- 4:55interested to do. - Yeah.
- 4:57- What about it?
- 4:58- Sure, I'll go on.
- 4:59So I really like this talk.
- 5:01It was by an associate professor
- 5:04named of Dettmer and he's
- 5:07a associate professor like I said
- 5:09at Harvard Medical School
- 5:11and in the States.
- 5:13And what he presented is
- 5:14because it's relevant to my work,
- 5:16that's why I really liked it.
- 5:17But what he presented is that
- 5:19he argued that the phosphorylation
- 5:21of alpha-synuclein serine 1:9,
- 5:23which we all know
- 5:25is the pathological protein found
- 5:27in dementia with Lewy bodies,
- 5:29may actually have a normal reversible
- 5:32physiological role during synaptic activity.
- 5:35So he showed a number of,
- 5:38well, a lot of figures,
- 5:39a lot of data, and one of the things,
- 5:42but what they use and is published now
- 5:44is in cortical neurons,
- 5:47they showed they're increasing
- 5:48the network activity using picrotoxin,
- 5:52it raised this phosphorylation
- 5:55at serine 1:9
- 5:56without damaging the total protein,
- 5:59total alpha-synuclein levels.
- 6:03They've done this in vivo
- 6:04and what they've shown again is that,
- 6:09under environmental enrichment
- 6:10also increased phosphorylation
- 6:13of the alpha-synuclein serine 1:9.
- 6:16And that anyway concluded that there
- 6:20is a physiological role of the phosphorylation.
- 6:23Doesn't mean it doesn't play any role
- 6:25in disease, but it shows
- 6:26that there is normal activity.
- 6:29Then they went and tried knock-ins,
- 6:32knock-downs, and mutations
- 6:34and what they showed is that
- 6:37in a knock-in mouse model where
- 6:41it prevented the phosphorylation,
- 6:43it showed that there was a redaction
- 6:45in an impaired hypercomplexity
- 6:48and cognitive deficits against suggesting
- 6:51this physiological phosphorylation,
- 6:53it contributes to the normal synaptic
- 6:56transmission and plasticity.
- 6:58Then he also showed some very,
- 7:00it's new and published data,
- 7:02which was really interesting to see.
- 7:05And what they did is that
- 7:07they introduced a phosphomimic.
- 7:10So it was mimicking phosphorylation
- 7:11and again, they could see all these
- 7:13impairments in the hippocampal
- 7:15and the long-term potentiation
- 7:18and the Y-maze performance.
- 7:23He said that it raises two interpretations.
- 7:26One that there is a dynamic
- 7:29reversibility of phosphorylation
- 7:31that is required or whether
- 7:32the mimic that they use,
- 7:34it does not function as a true
- 7:36phosphomimic in cells and it behaves
- 7:39more like a loss of function.
- 7:45Yeah, and then I'll keep on going,
- 7:47how about that.
- 7:48There's some last things I wanna say
- 7:52about it is that then they
- 7:53used the the PLK2 inhibitor,
- 7:56which we know that is an inhibitor
- 7:57that it could inhibit the phosphorylation
- 8:00of serine 1:9 of alpha-synuclein.
- 8:04And again, they showed that
- 8:05when they did this,
- 8:07they actually restored the function
- 8:09and the neural network
- 8:10and everything, which was really cool.
- 8:12So overall what they concluded is
- 8:14that alpha-synuclein serine
- 8:17once an phosphorylation
- 8:18has an important physiological
- 8:20activity dependent role of the synapses
- 8:23and it's distinct from its pathological
- 8:26accumulation in Lewy bodies.
- 8:29- That's so interesting. - And it is amazing.
- 8:32- It's really interesting to think
- 8:33that the proteins that misfold
- 8:35in neurodegenerative diseases
- 8:37also have an important function
- 8:40and perhaps, you know,
- 8:41this hyperphosphorylation
- 8:42or phosphorylation of alpha-synuclein,
- 8:45and tau, that actually it's part of
- 8:46a functional role and then somehow,
- 8:48that regulation goes wrong
- 8:50and that's maybe what leads to the pathology.
- 8:53So it is fascinating.
- 8:54- Yeah, exactly, that's why
- 8:55we liked it because
- 8:57compared the pathological role
- 9:00and the physiological role.
- 9:01So it actually shows that
- 9:07it will be good to look into another way.
- 9:09Like we just look things in a different
- 9:11perspective when we are doing this.
- 9:13Not think that this is just pathology,
- 9:15you know, there might be
- 9:16something else there that we don't know.
- 9:19So it would be good to be
- 9:20looking both the positive, I think,
- 9:21and the negatives the same where
- 9:23that makes sense. - This is going to be
- 9:24so important of course when we go
- 9:26to therapeutics, if you're just going
- 9:27to clear out this particular phospho
- 9:31type of alpha-synuclein
- 9:33and then actually, it's really important,
- 9:34it sounds like.
- 9:35And that sounds like they did some
- 9:36really robust experiments to show that
- 9:38that actually has a really functional role.
- 9:40- Yeah, exactly.
- 9:41And he was just saying that
- 9:42this is just preliminary,
- 9:44but just preliminary data
- 9:45and published preliminary data
- 9:47showing this, it means that
- 9:48there is more to come, you can see that
- 9:50there is a trajectory there.
- 9:53- Thank you, Athina,
- 9:53that really came across
- 9:54how excited you were about it. - Yeah.
- 9:56- That's fantastic, thank you.
- 9:59So Lauren, do you want to tell us
- 10:00a bit about what you found really
- 10:02interesting at the meeting? - Yeah, of course.
- 10:04So as I mentioned before,
- 10:05I come from a mitochondrial background.
- 10:06So one of the symposiums was looking
- 10:08at mitochondrial pathways
- 10:10and so I was instantly drawn towards
- 10:12that session, one talk in particular
- 10:14who was by Professor Sarah Berman,
- 10:16she's a assistant professor
- 10:18at the University of Pittsburgh.
- 10:20She was looking at essentially
- 10:24this complex one PET-binding protein,
- 10:28it binds to complex one
- 10:30in the mitochondrial respiratory chain.
- 10:32So the first complex oxidative phosphorylation
- 10:35and essentially, using this
- 10:37radioligand that binds to complex one,
- 10:39they're able to see the relative abundance
- 10:41of complex one in Parkinson's disease patients
- 10:44and people who have dementia Lewy bodies.
- 10:47So this was answering the research
- 10:48question of disease stratification.
- 10:52So I think typically, I mean,
- 10:53I definitely thought this years ago
- 10:55prior to my PhD, you know,
- 10:56Parkinson's disease is Parkinson's disease,
- 10:59but it seems that you have these
- 11:00different phenotypes that,
- 11:03you know, they're all different
- 11:05types, but under the same umbrella
- 11:06of Parkinson's disease of the shared pathology.
- 11:08So this talk was quite interesting
- 11:10because it really did kind of,
- 11:13it really questioned that narrative of,
- 11:15you know, different types of Parkinson's
- 11:17disease with different specific phenotypes.
- 11:20So the approach that they used was
- 11:21using this 18FBCPPEF PET,
- 11:26I know, the radioligand,
- 11:28so I'll just say that.
- 11:30And the binding is relative
- 11:31to the abundance of complex one.
- 11:34And what they found is
- 11:35as the disease duration
- 11:37of Parkinson's disease and dementia
- 11:38with Lewy bodies ensued in these patients,
- 11:41the binding of complex one actually reduced.
- 11:43So that's kind of supporting
- 11:45a lot of the literature that
- 11:46we've known for many years now knowing
- 11:47that we have complex one dysfunction
- 11:49in these alpha-synuclein endocrinopathies.
- 11:51But it was interesting that
- 11:52it was dependent on disease duration
- 11:55and it was also particularly
- 11:57interesting that they found that
- 11:59those that were actually
- 12:01complex one deficient were less likely
- 12:04to like be tremor heavy for their phenotype.
- 12:08Whereas, those who weren't deficient
- 12:10in complex one were more tremor
- 12:12heavy in their phenotype.
- 12:13So it's two kind of distinct phenotypes
- 12:15based on their complex one pathology,
- 12:18which I found particularly interesting.
- 12:20And something that I found that really,
- 12:23it struck me quite strongly
- 12:26because it does kind of relate
- 12:26to some of the things that
- 12:27I did for my PhD project as well,
- 12:29is that in the earlier stages,
- 12:32they found that there was actually,
- 12:33an initial increase
- 12:34in a peak in complex one binding.
- 12:36So it's telling us that
- 12:37there could be an initial compensator
- 12:39mechanism going on first
- 12:41and then as pathology ensues,
- 12:43the mitochondria become overwhelmed.
- 12:45And you know, as we get an increase
- 12:47in reactive oxygen species
- 12:48and a lot of stress, it just starts
- 12:50to downfall as pathology progresses.
- 12:54- Really interesting.
- 12:55So what I remember
- 12:57and Parkinson's disease
- 12:58is not my area of expertise,
- 13:00but complex one was highlighted
- 13:02particularly because of
- 13:03the drug-related induced
- 13:06Parkinson's disease, wasn't it?
- 13:07- Yes, so I think they found that
- 13:09in human, I think it was like
- 13:11an accidental sort of thing.
- 13:13So there were these people
- 13:14who had been taking this,
- 13:16it was like a opioid, it was the MPTP
- 13:19and then the metabolite MPP+,
- 13:21it was actually a complex one
- 13:22inhibitor and it mimicked
- 13:24and created these Parkinsonian
- 13:27phenotypes in the people
- 13:28who've taken this drug.
- 13:29And we also know that from animal models
- 13:31and cellular models, they add in rotenone,
- 13:33which is a complex one inhibitor
- 13:35also induces this mitochondrial
- 13:38phenotype associated with Parkinson's
- 13:39disease, but also, the motor symptoms
- 13:41in these animal models as well.
- 13:43- And so are they motor dysfunction heavy,
- 13:48those particular models or less so?
- 13:51- I don't actually know.
- 13:51So this is something that
- 13:52I found really interesting from this talk
- 13:54'cause I hadn't come across that before.
- 13:57Just the case of something
- 13:58so small as a mitochondrial complex,
- 14:00the deficiency in that can cause
- 14:02just such a difference
- 14:03in the phenotypic presentation.
- 14:05Yeah, I thought that was amazing.
- 14:08- It's really fascinating, isn't it?
- 14:09And I think what you
- 14:10said at the beginning about
- 14:11Parkinson's disease, not really
- 14:13just being one condition
- 14:15is so important at the moment
- 14:17because I think there's been a lot of
- 14:19publicity about understanding
- 14:21these neurodegenerative diseases
- 14:22as heterogeneous conditions
- 14:24with different protein misfolding
- 14:26and different mechanisms within them
- 14:29that we really need to try and pinpoint.
- 14:31So personal medicine is gonna be
- 14:33so important to sort of work out
- 14:35and stratify people into the right categories.
- 14:38- And just to add on that,
- 14:39I think that's also very general theme
- 14:41at ADPD is these biomarkers
- 14:43that is advancing a lot. - Yeah.
- 14:46- But it's both to stratify the patient
- 14:48and to identify them early
- 14:50but also, to understand the complexity
- 14:54of the Parkinson's disease
- 14:55and Alzheimer's disease.
- 14:57And there are actually a lot more
- 14:58comorbidity as well across these disorders
- 15:02and also just with neuropsychiatry
- 15:04and so on, so I really think
- 15:06it's important that we understand.
- 15:07- Yeah, I was just about to say,
- 15:09there's a lot of like co-pathologies
- 15:12and that every single protein,
- 15:14for example, alpha-synuclein,
- 15:16you can have the alpha-synuclein
- 15:18how it forms and aggregates
- 15:20within dementia, with Lewy bodies,
- 15:22it's different and Parkinson's
- 15:23is different in AD.
- 15:24So there's actually understanding
- 15:26the different co-pathologies
- 15:28and those proteins is,
- 15:30it will be really important for
- 15:32future treatments, I guess, yeah.
- 15:34- And as you mentioned,
- 15:35I think the way forward is
- 15:36personalised medicine
- 15:38so hopefully, someday, yeah. - Yes, maybe in time
- 15:43for you young people. - Yeah.
- 15:45- Hopefully hope, we really, really hope.
- 15:47Yeah, yeah.
- 15:48So Sofie, would you like to
- 15:50tell us what you learned? - Yes.
- 15:52So as I mentioned, I really have
- 15:55always been into Parkinson's disease
- 15:57and that's been my PhD focus and so on.
- 16:00So I would just take a step back
- 16:01and first talk about a talk by
- 16:05Daniel Kremens who is a co-director
- 16:08of Parkinson's Disease
- 16:09and Movement Disorder Centre.
- 16:11And he talked about the clinical
- 16:13needs in Parkinson's disease
- 16:15and how many unmet needs there are
- 16:18and we're not really treating everything.
- 16:20And especially, he talked about these
- 16:23non-motor symptoms
- 16:24that are not treated in patients
- 16:26and mentioned the cognitive impairment
- 16:28and a lot of patients,
- 16:30they also have hallucinations and so on.
- 16:32And this is just not treated,
- 16:34right now, levodopa is still
- 16:37the golden standard and has
- 16:39been that for 50 years
- 16:41and it works good initially,
- 16:43but it doesn't with time
- 16:46and may also be related to gut
- 16:49dysfunction, which is very common
- 16:51in Parkinson's disease patients.
- 16:53So I really think he put
- 16:54like good perspective that
- 16:57we need some disease modifying treatments
- 16:59and we need to understand the treatment
- 17:00better and we need new targets
- 17:03and we need to not only treat symptomatic.
- 17:08And in that regards,
- 17:09I also found both a poster
- 17:12and also, a talk on a non-dopaminergic
- 17:16target called, the p75 receptor,
- 17:19which is also a target we are looking at
- 17:22at Vesper Bio, so maybe,
- 17:24I'm also biassed about this,
- 17:27but the question is that targeting
- 17:29this neurotrophic or DAF receptor
- 17:32signalling improved neurodegenerative
- 17:34diseases and I was very glad
- 17:37and happy to see that it actually
- 17:40has some positive outcomes.
- 17:41So there was a talk from a lab
- 17:43in Montreal, so in Canada
- 17:45and then there was also a talk by
- 17:48Frank Longo who works at Stanford University
- 17:51and as I recall it, I hope it's correct,
- 17:53but he's developed small molecules
- 17:55to this target, himself
- 17:57and he has shown that
- 17:59very positive signals on cognition
- 18:02and motor behaviour in mice,
- 18:04but also, saw some reduced tau pathology.
- 18:08So also has some good indications
- 18:10in both Alzheimer's disease
- 18:12and Parkinson's disease
- 18:13and also, some good effects
- 18:15on somatic proteins.
- 18:17So I think it just really gives us some,
- 18:20yeah, that we can find some new mechanisms
- 18:24and some hope that we can treat
- 18:27more disease modifying
- 18:28and also in the progression stage
- 18:31and not just symptomatically.
- 18:33- It makes me wonder, you know,
- 18:35what p75, is it p75? - [Sofie] Yes.
- 18:38- What it does because
- 18:40is it something like p62 or...
- 18:43- It actually is,
- 18:45you can call it a DAF complex
- 18:46it actually sits in a complex
- 18:47with sortilin, which is our target.
- 18:50And so it actually causes apoptosis.
- 18:54So if you go and inhibit it,
- 18:56you of course, reduce apoptosis
- 18:58and then you mature
- 18:59the pro-neurotrophins or neurotrophins
- 19:02and then you induce the cell survival.
- 19:07Yeah, so it can be an indication
- 19:08of both FTD, Parkinson's disease,
- 19:12Alzheimer's disease and so on.
- 19:13So again, this very broad
- 19:15target for neurodegenerative disorders.
- 19:18- And do you know what triggers
- 19:19that pathway that goes
- 19:21through sortilin and p75 yet?
- 19:23I mean, is it the protein misfold,
- 19:25which is what I go to or... - It could be.
- 19:29Yeah, yeah, so it's pro-neurotrophins
- 19:32that bind to this sortilin p75 complex.
- 19:37So yeah.
- 19:39Yes. - Really interesting.
- 19:40So you're basically
- 19:41rescuing the cell survival. - Exactly, yeah.
- 19:44So you're reducing the apoptosis,
- 19:47but you're also inducing the cell survival.
- 19:50So I think that's a good way to go.
- 19:53- That sounds like a really
- 19:54interesting strategy,
- 19:55completely different maybe
- 19:56from some of the other ones. - Exactly, but I think
- 19:58that's very promising to see
- 20:00that all these very new promising mechanisms
- 20:04and targets to help these diseases.
- 20:07- Yeah, so I was thinking,
- 20:11one of the things that struck me
- 20:12at this meeting has been the emphasis
- 20:15on biomarkers been fascinating.
- 20:18And there were a few talks
- 20:19where they talked about diversity
- 20:22and whether those biomarkers,
- 20:24I mean, the one that's been
- 20:25very publicised is tau p2 and p7.
- 20:29- Yeah, yeah. - And whether those
- 20:31are suitable for biomarkers
- 20:34in other populations 'cause
- 20:36there is an emphasis on
- 20:37western populations generally.
- 20:39And I just wondered if any of you
- 20:41have picked up anything about that
- 20:42in terms of other cohort studies
- 20:45where they're looking at that.
- 20:48- I think we've been to a couple talks.
- 20:51So yeah, like you just said,
- 20:54they focus on p-tau217, but
- 21:00this was another talk,
- 21:01it was on the same biomarkers
- 21:03like session, but they picked up
- 21:05on other phosphorylation sites
- 21:07on the tau protein that they say
- 21:11that that could be used as a biomarker.
- 21:13So I think the other one was p264,
- 21:16if I'm not mistaken.
- 21:17Dunno if you remember. - I can't remember
- 21:19exactly which one it was. - I think it was 264,
- 21:20if I'm not mistaken. - Sounds familiar.
- 21:22- Yeah, well, it is on a different
- 21:25side of the protein,
- 21:27but they showed the use
- 21:28and number of techniques,
- 21:29I can't recall all of them right now,
- 21:31but they showed that that could also
- 21:34be used with a biomarker
- 21:35and that it comes early in disease.
- 21:39You can see there's a lot of people
- 21:40who are shifting and trying
- 21:42to find other biomarkers or like
- 21:44use other different like experiments,
- 21:48yeah, to understand anyway always.
- 21:52- Yeah, so that's gonna really
- 21:54help us with this personalised medicine,
- 21:56isn't it? - Yeah.
- 21:57- But we are really at an
- 21:59early point in biomarkers,
- 22:01but it's quite exciting.
- 22:02- Yeah. - They found this
- 22:03particular one that seems to work
- 22:05really well for at least,
- 22:06western population. - Like a very important
- 22:08point that you did raise though,
- 22:09you know, we're looking
- 22:11just at the west right now,
- 22:12it's very important to make sure
- 22:13that this is kind of
- 22:14an overarching thing that
- 22:16could help everyone around the world.
- 22:17And if it isn't then,
- 22:18you know, we need to work harder
- 22:19for this personalised medicine
- 22:21to really make sure that,
- 22:22you know, it's not prioritising
- 22:24the people that we've just
- 22:25focused on this particular
- 22:26mutation and modification,
- 22:28you need to be helping
- 22:29everyone who's suffering.
- 22:30- Yeah, and from a mechanistic point
- 22:31of view, it's actually really interesting
- 22:33'cause if you've got a biomarker
- 22:34that seems to work in one population
- 22:36and not in another,
- 22:37then it's really surprising, isn't it?
- 22:39Because then you think, well,
- 22:40actually maybe that isn't the mechanism
- 22:42of the disease and you need to
- 22:44open your mind a little bit more.
- 22:45Like you were saying about
- 22:47these other targets where you
- 22:48can think about upstream targets
- 22:51that are really important.
- 22:53- Yeah, and I think,
- 22:56it's hopeful to see that the techniques
- 22:58are also evolving in biomarkers.
- 23:00There's a lot of multi-omics posters
- 23:03up there, a lot of talks
- 23:05on fluid biomarkers.
- 23:06So I think the field is also evolving,
- 23:08which is great because it really
- 23:09gives us a better understanding
- 23:11of the disease and also just,
- 23:13yeah, identifying the patients early.
- 23:16And we need to do that because right now,
- 23:18we identified them very too late
- 23:22when they have already evolved
- 23:23the motor symptoms, for example,
- 23:24in Parkinson's disease,
- 23:25but we know they actually
- 23:27evolved or the disease occurs
- 23:30initially 10 years or approximately
- 23:33before they have the motor symptoms, so.
- 23:35- Yeah, it was also just to
- 23:37kind of build upon the point
- 23:38that you'd mentioned before,
- 23:40kind of how we were talking
- 23:41about there's not always
- 23:42just kind of one type of disease.
- 23:43You have different types.
- 23:44So I wonder if that kind of
- 23:46comes into, maybe, it could be that
- 23:49say p-tau217 is, you know,
- 23:53kind of common in the west for say
- 23:55like GWAS studies of what we see,
- 23:57but then it could be that, you know,
- 23:58there's another particular phenotype
- 24:00or like sub-Parkinson's disease
- 24:01or DLB that is more associated
- 24:03with other genes that are seen
- 24:04in other parts of the world as well.
- 24:06So really highlighting that.
- 24:08Yeah, it's very different,
- 24:10but very important to address all.
- 24:13- And just to add on that,
- 24:14there were actually some talks,
- 24:15obviously, there were a lot to go to,
- 24:17but I've seen the titles
- 24:19and there were a lot of studies
- 24:22that they were based, for example, on the east.
- 24:25So also there was specific
- 24:26like Chinese studies or like Amsterdam
- 24:30or well, Amsterdam is, yeah,
- 24:31still west, but there were like
- 24:33in Africa and all this.
- 24:35So there are initiatives now that
- 24:37they're making all these studies
- 24:40in other populations to try
- 24:41and understand whether
- 24:42what we see in the west
- 24:49and whether that relates
- 24:50back to those populations.
- 24:52So there is stuff going out there.
- 24:55- [Prof Louise] Yeah. - Yeah, it's just
- 24:57bringing it all together.
- 24:58- Yeah, and then that also
- 25:00makes me think about,
- 25:02there were a few talks focusing
- 25:04on women in terms of particularly,
- 25:07Alzheimer's disease.
- 25:08I'm not sure if there's
- 25:09a change in preference
- 25:10in terms of Parkinson's disease.
- 25:12And I wonder if you found that
- 25:15there were any talks on that,
- 25:18because it seems really important
- 25:19that we're focusing on sort of
- 25:22classifying people and stratifying
- 25:24the data to try and work out,
- 25:26you know, that hormones may have an effect.
- 25:29- Yeah, so we know from,
- 25:33so I mean, there probably was
- 25:35for dementia Lewy bodies
- 25:36and Parkinson's disease,
- 25:37but in dementia Lewy bodies,
- 25:38there's an increased prevalence
- 25:40in the male population.
- 25:41So I think there was one talk, actually,
- 25:44I can't remember specifically what it was,
- 25:45but it kind of raised the idea that
- 25:46there could actually just be
- 25:47sex differences in synaptic activity,
- 25:49which could then predispose
- 25:51to different pathologies
- 25:52because we know that there's links
- 25:53between hyperexcitability,
- 25:54near inflammation, downstream,
- 25:56mitochondrial dysfunction
- 25:57that can then be this vicious cycle.
- 25:59So it's really,
- 26:01I think very, very interesting,
- 26:02especially because a lot of the work
- 26:03that has probably been done years
- 26:05and years ago would've been on male mice
- 26:07and you know, it wouldn't have
- 26:08been fully representative
- 26:10of the female population,
- 26:11obviously, Alzheimer's disease being
- 26:14most prevalent in women, yeah. - I think that's
- 26:17still the case,
- 26:19I think you are more aware of it,
- 26:21but it's mostly male mice
- 26:23that are used in research.
- 26:24And I think we really need to shift
- 26:26and have both female and male
- 26:28because as you mentioned, more females,
- 26:31they get Alzheimer's disease. - Yeah, yeah.
- 26:33- Yeah, but also, yeah,
- 26:36talking about patients and so on.
- 26:38Just taking a step back,
- 26:39what I thought a lot about
- 26:41during this conference is that
- 26:43there's a lot of cool science
- 26:44and advanced techniques and so on,
- 26:46but we are not really thinking
- 26:48about the patient perspective.
- 26:50And I actually came across a poster
- 26:51yesterday by Jacqueline Shapiro
- 26:54from something called, Cure GRM,
- 26:57which is patient advocacy organisation
- 27:01who raises focus on
- 27:02FTD patients with the GRM mutation.
- 27:05And she actually had a poster
- 27:07where she told her family story
- 27:10and had a lot of photos with
- 27:13her family and who had unfortunately,
- 27:15had FTD also because it's very genetic
- 27:19disease and I think it was so strong
- 27:21and it was a very personal storytelling.
- 27:24And I just think we need to remember
- 27:26that without the patient voices,
- 27:29they really drive the awareness,
- 27:31but also the research because
- 27:32we need them to donate a lot.
- 27:34And I think sometimes,
- 27:35I talk to her and she was like,
- 27:37"I just feel like a number sometimes."
- 27:38And I really think we need to focus
- 27:41or just remember
- 27:43why are we doing what we're doing
- 27:44because of course, we know it's important.
- 27:48I think she had a very important point.
- 27:50- That is a really excellent point.
- 27:52I was going to ask you
- 27:53about programme, Lauren,
- 27:54'cause you mentioned it, didn't you?
- 27:56And I know, yes, that there's
- 27:58a variant form that causes FTD.
- 28:01- Exactly. - And yeah, I'm surprised
- 28:05that there aren't more patients
- 28:08or carers sort of involved in this meeting,
- 28:11but then it is quite
- 28:12sort of in depth high science. - Yeah.
- 28:17- It is, but I think it's important
- 28:21'cause you know, there were sessions
- 28:24that were like spread out
- 28:25or there was other, you know,
- 28:28obviously, we had some breaks,
- 28:30so it would be really nice,
- 28:31if on those breaks, we had carers
- 28:33talking or even patients like being around.
- 28:37I think that will make everyone
- 28:39understand and basically,
- 28:41recall why I'm doing this,
- 28:43why I'm doing research.
- 28:45And yeah, it's really nice
- 28:48'cause we've seen thousands exhibits,
- 28:51there were a lot of exhibitions
- 28:53like that we went to during the breaks
- 28:56where it be really good if you had one stand.
- 28:58If it's just, yeah, just one stand there
- 29:01where people talking about their experience,
- 29:04especially the carers, I guess,
- 29:06it's really hard for them,
- 29:07let's just not forget them.
- 29:08It's not just the patients,
- 29:09the carers as well.
- 29:11- I think it's important
- 29:11that they have a voice, especially
- 29:12for public engagement and patient engagement.
- 29:15You know, letting them have a say,
- 29:18you don't want them to feel
- 29:18like a number statistic, you know.
- 29:20- [Prof Louise] Yeah, yeah. - You wanna keep them
- 29:21updated with where the research is going.
- 29:24- And the genetic forms are obviously,
- 29:26incredibly difficult because people
- 29:27actually follow their parents
- 29:31being ill and declining,
- 29:32but then know that they have the gene too.
- 29:35So it's really shocking
- 29:36to have to live with that.
- 29:38I can't even imagine, so yeah.
- 29:41- Yeah. - And yeah, that makes
- 29:42it so important then, doesn't it?
- 29:43- Yeah, a 100%.
- 29:44And I think you also mentioned
- 29:46this Sofie, about, you know,
- 29:47catching, well, not catching,
- 29:49but you know, determined presymptomatically,
- 29:50that is the most important part to look at.
- 29:53And it is interesting that even
- 29:55for Parkinson's disease, Alzheimer's,
- 29:56dementia Lewy bodies,
- 29:57you see these changes that go
- 29:59unnoticed like decades before.
- 30:01And even, especially
- 30:03when you were talking about
- 30:04the gut and the microbiome,
- 30:06how that can actually have a big role
- 30:08in actually the onset
- 30:09of Parkinson's disease especially.
- 30:13Yeah, considering how many years
- 30:14it is prior, I think it's very important
- 30:16to really hone in on these presymptomatic
- 30:19and prodromal diseases.
- 30:21- Absolutely, and then we might
- 30:22be able to identify people
- 30:24we can treat early enough. - Yeah, that's the goal.
- 30:26Yeah, there was a striking code,
- 30:29I actually took Lauren a photo,
- 30:32it was the Michael J. Fox Foundation
- 30:34and they had Michael J. Fox on the poster
- 30:38and he said, the Parkinson's disease
- 30:41and cure, we're gonna find
- 30:43the Parkinson's disease cure
- 30:44brain in order to do that is
- 30:46because we're all gonna work together.
- 30:49So he said, "The reason why
- 30:51we're gonna find the cure is
- 30:51because we're all working together."
- 30:54And that striked me.
- 30:56I was like, okay, this is really nice.
- 30:59So I guess, that actually made us
- 31:03think that we need to publish
- 31:04what we're publishing,
- 31:05we need to tell other scientists
- 31:08and scientists, you know,
- 31:09need to talk with each other
- 31:10in order to, you know, share the insights,
- 31:13and share the thoughts
- 31:14and how we can like go forward
- 31:16with this so we can get closer-
- 31:18- I think that's very important, yeah.
- 31:20- And also just to communicate
- 31:21the negative data as well. - Yeah.
- 31:23- Because I think that's
- 31:24also been a problem in the field.
- 31:25And I think in regards to that,
- 31:27I think the Novo Nordisk,
- 31:30the Evoke talks, they were also very good.
- 31:33I think it was very inspiring
- 31:35and very clear communicated,
- 31:37but also very transparent how
- 31:39they communicated negative results
- 31:43and were just very honest.
- 31:44And I think that's so
- 31:46important for the field as well,
- 31:47because we also learn a lot
- 31:50from negative results. - Yeah, exactly.
- 31:53- I've also been to a talk yesterday,
- 31:55it was not my area,
- 31:56but it was about how A beta 42
- 32:00and A beta 40, they get degraded in the liver.
- 32:03And the first slide the girl had on,
- 32:06it was all the studies
- 32:08and all the papers that came out.
- 32:10Some of them were saying,
- 32:11"Oh yes, that is true."
- 32:12And then it was like,
- 32:14"Oh no, it's not.
- 32:15And then, "Oh yes."
- 32:16So you could see like the different papers.
- 32:18And then she went on to talk
- 32:19about her research
- 32:21and how she found that A beta 42
- 32:23gets the greater faster in the liver
- 32:25compared to A beta 40 and all this,
- 32:28but she showed that
- 32:29there's still this debate out there.
- 32:32Yeah, which is really good
- 32:34because this is how we're gonna
- 32:36address the questions, I guess.
- 32:37- Yes, so that openness,
- 32:38I was really, really informed
- 32:40by the Evoke study on the GLP-1 inhibitors.
- 32:43I just thought that the way,
- 32:44it was a real exemplar of how
- 32:46a company who presumably
- 32:48have put an enormous amount of money
- 32:49into these trials have actually
- 32:52offered to share the data,
- 32:54to publicise exactly what they've done.
- 32:56And perhaps, this will lead to
- 32:58something in the future,
- 33:00we don't know, but for them
- 33:02to have really talked about it,
- 33:03I think it's fascinating.
- 33:05I mean, it seems sort of
- 33:06plausible that it might be a good target,
- 33:10but obviously, not in that trial.
- 33:12And so interesting to see
- 33:13what will happen next in that area.
- 33:16I just hope that they keep being open.
- 33:19- Yes, I agree. - Yeah, I mean,
- 33:21the best thing would be, you know,
- 33:23like a repurpose in a drug
- 33:24that already exists, I suppose,
- 33:25you know, there's actually evidence for,
- 33:28I think it's metformin,
- 33:29the diabetes drug and it's actually
- 33:31reduced in those who have diabetes
- 33:33and that are on metformin
- 33:35there's a reduced incidence
- 33:36of Alzheimer's disease.
- 33:38So I think even if it's not just
- 33:40neuroscience, but everyone collaborating
- 33:41and everything that we know,
- 33:42you know, and yeah.
- 33:45- Yeah, so the talk we went
- 33:47this morning by Doug Orsland, yeah,
- 33:50he was- - Who was it?
- 33:52- Doug Orsland, I think, yeah.
- 33:55I think, yeah, so yeah.
- 33:59Well, I've seen his talk before
- 34:02once in another conference
- 34:03and it was really interesting.
- 34:04So we just rushed this morning
- 34:05to get here to see his talk.
- 34:06But he was talking about
- 34:08the new perspectives in dementia
- 34:09with Lewy bodies and Parkinson's disease
- 34:11and all the clinical trials
- 34:13that this happening.
- 34:16And I think they've also used,
- 34:17was it Metformin that they were using?
- 34:20- Yeah, I think. - It was, yeah.
- 34:21So they're using this drug,
- 34:22so for DLB and they showed some
- 34:25cognitive advances and that is great.
- 34:28So just said that
- 34:30the Reese clinical trials coming out
- 34:32for these diseases that is dementia
- 34:33with Lewy bodies, but we need more.
- 34:36Yeah, so it was really good.
- 34:39It was really, really good.
- 34:42- Really exciting meeting.
- 34:44So we probably should be wrapping up.
- 34:46So I'm just thinking,
- 34:48was there any particular research area
- 34:50that any of you just think,
- 34:52you know, is the future
- 34:54where this field should be really
- 34:56focusing their ideas
- 34:59and where think we should all be going next?
- 35:02- Big question. - That's a big question.
- 35:04- Yeah, yeah.
- 35:05I think we all have
- 35:06our own preferences and buying.
- 35:07- Yeah. - You know, our backgrounds.
- 35:09- I think the bio is a very,
- 35:13yeah, theme that goes again along
- 35:15in many talks, I think yeah,
- 35:18understanding, but for just
- 35:20a researcher as we are,
- 35:21I think just coming to these
- 35:22conferences and getting inspired
- 35:24on what's moving in the field
- 35:26and which models to use
- 35:28to be more translatable,
- 35:30for example, to the diseases.
- 35:32And I've learned a lot on
- 35:34which in vivo models also to use
- 35:36in the field and they get more and more,
- 35:41yeah, specific also to, for example,
- 35:45if you have lysosomal dysfunction
- 35:46and Parkinson's disease,
- 35:47you can actually create a mouse model
- 35:49that is linked to a GBA mutation and so on.
- 35:54And also just to see that a lot of
- 35:57complex cell models also evolving
- 35:59and being validated well.
- 36:01And I think that's really
- 36:03a good way to go in the research field
- 36:05to have these complex models
- 36:07that really represent the human body
- 36:09and the disease the best way.
- 36:12- Yeah, yeah, good point, I agree.
- 36:13And I suppose, I thought maybe
- 36:17you meant in terms of like the theme
- 36:19of like where research is mainly going.
- 36:21I'd say there was a lot of focus on
- 36:23neuroinflammation a few years ago,
- 36:26but I'd say, I think because
- 36:28of the link between, you know,
- 36:29where we talk about metformin
- 36:31and how, I think there's a lot
- 36:36to speak about when
- 36:37it comes to like hormonal changes.
- 36:41You know, if you have diabetes,
- 36:43all these different other factors
- 36:45like epigenetic modifications.
- 36:47I just think it's really important
- 36:48that it's kind of seen more
- 36:50as kind of a whole,
- 36:51I know it's easy to really
- 36:53hone in on just one particular thing,
- 36:55especially when we're researchers
- 36:55and we're looking at literally
- 36:57like molecular basis, but yeah,
- 37:00I think maybe if there's
- 37:02more collaboration between clinicians
- 37:03and the researchers to kind of have
- 37:05more of those discussions,
- 37:06I think that would help the way forward.
- 37:09- And that reminds us about
- 37:10being patient-centered, doesn't it?
- 37:11- Yeah. - Because one of the things
- 37:13that I've talked about is
- 37:14that Alzheimer's disease, for example,
- 37:16takes your whole life to develop
- 37:19and it's about, you know,
- 37:20the experiences and the genetics
- 37:22and the environment of the person
- 37:24and what leads to that
- 37:25outcome and presumably,
- 37:27the same for Parkinson's disease.
- 37:28So just thinking about
- 37:30exactly the hormones and the effects.
- 37:32One thing I thought was missing actually,
- 37:35which I was a bit surprised about,
- 37:36was there was nothing about infection.
- 37:39So I think a few years ago,
- 37:40there was an idea that if you
- 37:42are protected against herpes virus,
- 37:44that you would
- 37:46have a resilience to Alzheimer's disease.
- 37:48And I didn't see anything
- 37:50about that this time.
- 37:51- I didn't really catch
- 37:52anything like that. - No, no.
- 37:53- It was quite interesting
- 37:54'cause I do think that if you are to get
- 37:58a severe infection then, you know,
- 38:00it sort of makes sense, doesn't it?
- 38:02That it could trigger changes
- 38:03and dysfunction, so it's quite
- 38:06interesting that that didn't come up.
- 38:08- No, that's true
- 38:09and that it's actually also
- 38:10true with the neuroinflammation.
- 38:11I think there's been a lot
- 38:13of talks focusing on the lipids
- 38:15and the lysosomes especially,
- 38:17in both Alzheimer's and Parkinson's.
- 38:21(upbeat music)
- 38:26- So it's been a really fantastic conversation.
- 38:28I've really enjoyed talking to you all.
- 38:31And I just wondered if any of you
- 38:34presented posters or talks
- 38:35at this meeting and whether you
- 38:37wanted to say a little bit
- 38:38about what you did.
- 38:41- You can go. - Oh yeah, yeah.
- 38:43I did have a poster.
- 38:45I was on the first shift 'cause
- 38:47there was two shifts for the whole conference.
- 38:50And my poster focused more on
- 38:53the cytoplasmic to nuclear translocation
- 38:57that I see in dementia with Lewy bodies
- 38:59and Alzheimer's disease cases.
- 39:03So I am using postmortem brain tissue
- 39:05as well as, brain slides
- 39:07from the frontal cortex of patients
- 39:09from the control cases,
- 39:11prodromal Alzheimer's disease
- 39:12and dementia with Lewy bodies.
- 39:14And specifically, for the postmortem
- 39:16brain tissue, what I do is,
- 39:17I fractionate the tissue into the nucleus
- 39:19and the cytoplasmic fractions.
- 39:21And what I saw was really interesting,
- 39:23we still don't understand it
- 39:24when we're still in the process
- 39:25of increasing our end numbers,
- 39:27is that we do see there's differences
- 39:29in the cytoplasmic
- 39:30and the nuclear fractions on dementia,
- 39:33sorry, in DNA damage repair proteins
- 39:35'cause like I said before,
- 39:36I'm interested in the role
- 39:38of these proteins and in disease
- 39:43and we do see that there is a downregulation
- 39:46of this proteins of the Ku70
- 39:48and the APEX1 protein
- 39:50in the cytoplasmic fraction.
- 39:52And there is a potential
- 39:54upregulation in the nuclear fraction.
- 39:57We're still trying to understand,
- 39:58there's a lot of variability especially
- 40:00in dementia with Lewy bodies.
- 40:01Which brings back to the question
- 40:03actually, and these disease dementia
- 40:05with Lewy bodies actually might
- 40:06not be pure that all these
- 40:08co-pathologies that we were talking
- 40:09before actually contribute to all
- 40:11the changes that we observe
- 40:12and this variability that we observe.
- 40:14But then I've also used brain tissue sites
- 40:18to stain for Ku70 and APEX1 proteins.
- 40:22And again, I do see this shift
- 40:24from the cytoplasm into
- 40:25the nucleus in Alzheimer's disease
- 40:27and dementia with Lewy bodies cases,
- 40:29which is really striking.
- 40:30So then something else that
- 40:35I am working on is cellular models.
- 40:36So we try to have a shift
- 40:38and get a step back to understand
- 40:41the mechanism of why
- 40:43we're seeing what we're seeing.
- 40:44So I am using the SH-SY5Y cells,
- 40:48some differentiate in neuron like phenotypes.
- 40:51And in order to induce DNA damage,
- 40:53I use etoposide,
- 40:54which is a top mastocytosis 2 inhibitor
- 40:57and something that's really striking.
- 40:59And what we observe is that
- 41:01when we induce DNA damage using
- 41:03this chemotherapeutic drug etoposide,
- 41:08I see that there is an increase
- 41:10of phosphorylated nucleus in
- 41:12with increase in concentrations
- 41:13of the drug without any changes
- 41:16in the total levels of alpha-synuclein
- 41:18and the total levels of tau.
- 41:20And I don't see any phosphorylation of tau.
- 41:22That's why I really love that talk
- 41:24as well 'cause they do see
- 41:25like similar things.
- 41:27And also, so we're in the process
- 41:30of doing further experiments on this
- 41:32and like splitting into
- 41:33the nuclear cytoplasmic fractions.
- 41:36And also, we've also produced
- 41:39generated some preformed fibrils
- 41:41from alpha-synuclein using
- 41:43the Michael J. Fox Foundation protocol.
- 41:46And we wanna use these preexisting
- 41:48pathology, the preformed fibrils
- 41:50with and without the DNA damage
- 41:52inducing agent atococyte
- 41:54to see what comes first.
- 41:56So try and understand basically,
- 41:57the basics behind what we see.
- 42:01Yeah, so it's an exciting work.
- 42:03But yeah, that is all me.
- 42:05That's what my poster was about.
- 42:06- Well, that sounds really interesting.
- 42:08So I really look forward to
- 42:09hearing what happens in the end.
- 42:11- Thank you very much.
- 42:12Yeah, yeah. - [Prof Louise] So exciting.
- 42:13- Thank you.
- 42:14- [Prof Louise] What about you, Lauren?
- 42:15- So I also had a poster.
- 42:17So I actually have only recently
- 42:18started my postdoctoral position
- 42:20at the University of Dundee,
- 42:21but I have my finalised work
- 42:24for my PhD at Newcastle University.
- 42:27So that's what I presented in the poster.
- 42:29So what I've shown using
- 42:31a transgenic mouse model
- 42:32of ultrasound endocrinopathies,
- 42:34A30P mouse, I looked at
- 42:36a presymptomatic age range
- 42:37between two and four months.
- 42:38And I specifically wanted to look
- 42:40at the hippocampus
- 42:42and the hippocampal neurons.
- 42:44And it was actually kind of like
- 42:46an accident as to how I found this
- 42:48is when I zoomed in on the images
- 42:49and the parietal layer,
- 42:50I saw that there was kind of
- 42:51differential expression of
- 42:52alpha-synuclein in the A30P mouse
- 42:55between cells of the same mouse.
- 42:56And I thought it was quite strange.
- 42:58I did a frequency distribution
- 42:59and I categorise these cells
- 43:01that are having low, medium,
- 43:03high levels of alpha-synuclein.
- 43:04And I went to look at how the mitochondrial
- 43:09respiratory chain subunits
- 43:10are impacted when there is either
- 43:11low, medium or high levels of alpha-synuclein.
- 43:13And interestingly, we found that
- 43:15in the cells that had the very
- 43:16high levels of alpha-synuclein,
- 43:17there was a significant increase
- 43:19in mitochondrial complex one subunit
- 43:21and also, mitochondrial complex four.
- 43:23Which is interesting because
- 43:24from what Sarah Berman shown in
- 43:27patient data that there
- 43:28was actually initial increase.
- 43:30So I thought it kind of linked very nicely,
- 43:33I know that I was using a mouse model,
- 43:35but it's reassuring that, you know,
- 43:37it's actually seen in some patient data
- 43:39as well that it might be a commonality of
- 43:42this compensatory response initially.
- 43:45- That's what conferences
- 43:46are for really, isn't it,
- 43:47when you really get some sort of
- 43:49backup on what you think
- 43:50and then you start thinking about
- 43:53how that compares to other people.
- 43:54That sounds fantastic. - Yeah.
- 43:56- Really exciting stuff. - Thanks.
- 43:59- What about you, Sofie? - Yes, yes.
- 44:00So I- - You gave a talk
- 44:02for a YouTube video. - Yes, that's true, yes.
- 44:06So I did present a poster as well.
- 44:11And that was for Vesper Bio,
- 44:12which I just mentioned before.
- 44:13We developed small molecules,
- 44:15sortilin inhibitors,
- 44:17and we actually have one called,
- 44:19(indistinct) which has just finalised
- 44:21or completed a Phase 1b/2a trial.
- 44:24And we have a talk later today
- 44:27on the safety and the efficacy of that.
- 44:29And I can spoil alert, it's good.
- 44:33But I did present
- 44:34more the preclinical stuff.
- 44:36So as I mentioned, we increase
- 44:38by blocking the sortilin receptor,
- 44:40we increase the very important
- 44:42progranulin protein in the brain.
- 44:44And we do it both extracellularly,
- 44:45but also intracellularly.
- 44:47So by that, we improve the lysosomal
- 44:49function, it's neuroprotective,
- 44:52but also, anti-inflammatory.
- 44:54So that's very good.
- 44:56And then I talked a lot about
- 44:58the potential we have in Parkinson's
- 44:59disease because that we
- 45:01are in a very preclinical stage.
- 45:04And that's especially with
- 45:05the DAF complex I mentioned before.
- 45:07So the sortilin p75 DAF complex,
- 45:10which especially is on
- 45:11the dopaminergic neurons in
- 45:13the substantia nigra pars compacta.
- 45:15So very important
- 45:16for Parkinson's disease patients.
- 45:18So when we block that,
- 45:19we increase the cell survival.
- 45:21And right now,
- 45:22we're in a very beginning stage.
- 45:24So we've actually tried with
- 45:26the AV, the viral alpha-synuclein mouse model.
- 45:30Unfortunately, it was a very harsh model.
- 45:33So we saw 90% loss of
- 45:36the dopaminergic cells, which is a lot.
- 45:39So unfortunately, we couldn't really
- 45:41rescue anything that wasn't there.
- 45:44So I mean, we've also really
- 45:46learned a lot from this conference
- 45:48and got a lot of good feedback
- 45:50on what the next steps are.
- 45:51And we are very lucky to have
- 45:53a funding from the Michael J. Fox
- 45:55as well, which are really incredible
- 45:57to work with and have also
- 45:59had a lot of good talks with them
- 46:00here at at the conference.
- 46:03(upbeat music)
- 46:08- So that brings us to
- 46:10the end of our ADPD Conference,
- 46:12reflections from Copenhagen.
- 46:14Thank you all so much for
- 46:15your fantastic input and discussion.
- 46:18I really enjoyed it.
- 46:18I hope you did too.
- 46:20Good luck on going home,
- 46:23although, don't have to go far.
- 46:25- Not so far.
- 46:27- If you want to learn more about
- 46:29the research we discussed today,
- 46:30you can find links and further
- 46:32information in the show notes.
- 46:34On our YouTube channel,
- 46:36you'll find many of the posters short recordings.
- 46:38I've listened to them and watched them
- 46:39and they are really fantastic.
- 46:41I'm so impressed with the way
- 46:42that people are able to communicate
- 46:44their research as you've seen today.
- 46:47So the researchers will share
- 46:48short summaries of their work
- 46:50presented at the conference.
