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.
