## 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 constitutes the essential priming signal for pro-IL-1β and NLRP3 upregulation. Following endocytic upta

## Molecular Mechanism and Rationale The core molecular mechanism involves a two-step process where intestinal dysbiosis creates systemic NLRP3 inflammasome priming through bacterial lipopolysaccharide (LPS) translocation, followed by secondary activation triggers in the central nervous system. Circulating LPS binds to Toll-like receptor 4 (TLR4) on peripheral monocytes and brain-resident microglia, initiating NF-κB-mediated transcriptional upregulation of NLRP3, pro-IL-1β, and pro-caspase-1 co
