Enhancing autophagy specifically in reactive astrocytes through targeted mTOR inhibition could accelerate clearance of accumulated complement proteins and reduce chemokine secretion. This approach would reset astrocytes to a less reactive state while maintaining their protective functions.
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.
## Molecular Mechanism and Rationale
Stress granules (SGs) are membraneless, phase-separated ribonucleoprotein organelles that form through liquid-liquid phase separation in response to cellular stress, representing a critical intersection between RNA metabolism and neuroinflammation in neurodegenerative diseases. The formation and persistence of pathological stress granules is orchestrated primarily by G3BP1 (GTPase-activating protein SH3 domain-binding protein 1) and its paralog G3BP2, which
