Alzheimer’s genetic risk factor Bin1 controls synapse vesicle exo-endocytosis in inhibitory synapses
16 Jul 2025
Abstract excerpt
BIN1, a late-onset Alzheimer's disease (LOAD) risk gene, is an endocytic regulator with an unclear synaptic function. We find Bin1 more prominently in inhibitory synapses (vGAT positive) than in excitatory ones (vGLUT1 positive). Bin1 knockdown reduces inhibitory synapses independently of Aβ42 production, increasing GABA release from the remaining synapses due to accelerated vGAT exocytosis and endocytosis, which...
