## Mechanistic Overview
Direct C1q Binding Enables FcγR-Independent Complement Activation on Tumor Cells starts from the claim that modulating not yet specified within the disease context of molecular biology can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview Direct C1q Binding Enables FcγR-Independent Complement Activation on Tumor Cells proposes that modulating the target gene within the disease context of molecular biology can redirect a disease-
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
