1677-Astrocyte Reactivity in Tuberous Sclerosis
Tuberous sclerosis complex is a genetic neurodevelopmental condition linked to severe epilepsy and brain malformations known as cortical tubers. Researchers utilized human brain organoids to investigate how a second-hit mutation in the TSC2 gene impacts neural progenitor cells during development. The findings reveal that mTORC1 hyperactivation drives mutant cells to autonomously differentiate into reactive astrocytes characterized by inflammation and altered gene expression. These astrocyte abnormalities emerge independently of seizure activity, highlighting glial dysfunction as a fundamental…
