712-The Gut Microbiome and Cognitive Decline in Ageing Mice
Research conducted by Cox et al. demonstrates a significant connection between gut microbiome changes and cognitive decline during the aging process. By studying mice, scientists found that an increase in the bacterium Parabacteroides goldsteinii triggers the release of fatty acids that inflame the immune system. This inflammatory response disrupts signaling through the vagus nerve, ultimately reducing activity in the hippocampus, a brain region vital for memory. Experiments showed that transferring "old" microbes into young mice impaired their memory, while antibiotic treatments or specific…
