Glycolytic Inhibition Selectively Blocks Reactive Astrocyte Complement Production
🧪 Overview
Since reactive astrocytes require increased glucose metabolism to produce complement proteins and chemokines, selective inhibition of astrocytic glycolysis (via PFKFB3 targeting) could break the feedback loop without affecting microglial IL-1α/TNF production. This would preserve beneficial microglial functions while stopping pathological amplification.
Debate provenance: derived from debate `sess_sda-2026-04-01-gap-009` on question: Microglia activate astrocytes via IL-1alpha/TNF/C1q, and reactive astrocytes feed back to microglia via complement/chemokines.. Consensus signal: domain_expert, skeptic, synthesizer, theorist discussed the mechanism terms Astrocyte, Blocks, Complement, Glycolytic, Inhibition, PFKFB3, Production, Reactive. Novelty signal: skeptic-discussed-with-qualified-concession.
