**Molecular Mechanism and Rationale**
The central molecular mechanism underlying this hypothesis involves the intricate interplay between TANK-binding kinase 1 (TBK1) and selective autophagy receptors in the clearance of stress granules containing G3BP1 (GTPase-activating protein SH3 domain-binding protein 1). Under cellular stress conditions, such as oxidative stress, heat shock, or ER stress, RNA-binding proteins including G3BP1, TIA-1, and TIAR rapidly condense into membrane-less ribonucleop
Gut dysbiosis leads to LPS translocation, triggering intestinal and systemic inflammation via TLR4/MyD88/NF-κB signaling, promoting α-synuclein pathology. The peripheral gut barrier is the most viable intervention point, though CNS microglial TLR4 activation remains mechanistically tenuous. Best therapeutic approach: zonulin antagonists (larazotide) for gut barrier restoration combined with NLRP3 inflammasome inhibition rather than direct TLR4 blockade.
