Description

The study observes that microglial SIRPα expression decreases alongside AD progression in human tissue, but the underlying mechanisms driving this decline are not explained. Understanding this could reveal therapeutic targets to preserve synaptic protection.

Gap type: unexplained_observation Source paper: Loss of microglial SIRPα promotes synaptic pruning in preclinical models of neurodegeneration. (2021, Nature communications, PMID:33795678)
