Metabolic Reprogramming of Pruning Microglia
🧪 Overview
Microglia adopt different metabolic states that correlate with their functional phenotype. Metabolic modulators that shift microglia toward oxidative metabolism could reduce their synaptic engulfment capacity while maintaining other protective functions like debris clearance and trophic support.
Debate provenance: derived from debate `sess_sda-2026-04-01-gap-v2-691b42f1` on question: Synaptic pruning by microglia in early AD. Consensus signal: domain_expert, skeptic, synthesizer, theorist discussed the mechanism terms Metabolic, Microglia, PKM2, Pruning, Reprogramming, clearance, synaptic. Novelty signal: skeptic-discussed-with-qualified-concession.
