A credible refinement is that any true amplification is not universal across cell types, but emerges most strongly in professional phagocytes with high endogenous LRRK2 activity, chronic cargo load, and active endolysosomal remodeling. This would reconcile modest blood-cell baseline effects with larger functional consequences in microglia/macrophages relevant to inflammatory and trafficking phenotypes.
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.
