Astrocyte-Intrinsic NLRP3 Inflammasome Activation by Alpha-Synuclein Aggregates Drives Non-Cell-Autonomous Neurodegeneration
h-var-adfecef68a
## Molecular Mechanism and Rationale
The NLRP3 inflammasome pathway in astrocytes represents a critical neuroinflammatory cascade initiated by alpha-synuclein (α-Syn) aggregate recognition and subsequent intracellular danger signal processing. Extracellular α-Syn fibrils bind to astrocytic Toll-like receptor 2 (TLR2) and CD44 surface receptors, triggering MyD88-dependent NF-κB activation that con
