C1q (classical complement cascade initiator) is upregulated in AD brain and tags synapses for microglial phagocytosis via C3-CR3 signaling. This excessive, activity-independent pruning underlies early synaptic loss before plaque deposition. The hypothesis is supported by compelling mechanistic studies (Hong et al. 2016) and Annexon Pharmaceuticals' ANX005 antibody is in clinical development. The mechanism explains early cognitive decline independent of amyloid burden, addressing a critical thera
## Mechanistic Overview
NFκB/C1Q SASP Modulation for Synaptic Protection starts from the claim that modulating not yet specified within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview NFκB/C1Q SASP Modulation for Synaptic Protection starts from the claim that modulating not yet specified within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads:
