Validation experiment designed to validate causal mechanisms targeting SIRPα in mouse models of Alzheimer's disease. Primary outcome: synaptic loss, microglial engulfment, cognitive impairment
This experiment involved modulating microglial SIRPα expression in established mouse models of Alzheimer's disease to investigate its role in neurodegeneration. The researchers examined the effects of altered SIRPα expression on synaptic loss, microglial engulfment activity, and cognitive function. This comprehensive study measured multiple outcomes including synaptic integrity, microglial phagocytosis, and behavioral performance to understand how SIRPα regulates synaptic pruning in the context of neurodegeneration.
Modulation of microglial SIRPα expression in Alzheimer's disease mouse models followed by assessment of synaptic loss, microglial engulfment activity, and cognitive testing
Loss of microglial SIRPα results in increased synaptic loss, enhanced microglial engulfment, and worsened cognitive impairment
Significant increases in synaptic loss and cognitive deficits in mice with reduced microglial SIRPα
