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.
PD patients exhibit dual ENS pathology: α-synuclein aggregation within enteric neurons and progressive loss of cholinergic/nitrergic neurons. This disrupts gut motility causing constipation, SIBO, and dysbiosis blooms (H. pylori, Klebsiella). Enteric glial reactivity and S100B release complete a feedforward inflammatory loop. Clinical observations are robust; the primary weakness is circular logic regarding initiating event. Gut-directed therapies (prokinetics, H. pylori eradication, FMT) may br
