**Molecular Mechanism and Rationale**
The OPTN/TBK1 phosphorylation cascade represents a critical quality control mechanism for stress granule homeostasis, with mutations in either component leading to selective accumulation of pathological stress granules that drive motor neuron degeneration in amyotrophic lateral sclerosis (ALS). The molecular foundation of this hypothesis centers on the differential recognition and clearance of physiological versus pathological stress granules through distin
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.
