Complement-Independent SPP1 Signaling Disruption
🧪 Overview
Targeting actin-binding proteins and Rho GTPases downstream of SPP1 to selectively block synaptic engulfment while preserving complement-mediated pathogen clearance
Debate provenance: derived from debate `sess_SDA-2026-04-15-gap-pubmed-20260406-062118-e3613755` on question: What molecular mechanisms mediate SPP1-induced microglial phagocytic activation and synaptic targeting?. Consensus signal: domain_expert, skeptic, synthesizer, theorist discussed the mechanism terms Complement-Independent, Disruption, RHOA, SPP1, Signaling, clearance, signaling, synaptic. Novelty signal: skeptic-discussed-with-qualified-concession.
