A specific threshold represents the point at which amyloid-driven tau pathology has been reduced below the threshold required to sustain neurodegeneration. However, the threshold is operationally undefined—the <0.15 pg/mL value lacks prospective validation and is likely derived from cross-sectional amyloid status cutoffs, not treatment cessation studies. The proposed pragmatic trial to validate this threshold has never been conducted and carries significant ethical and investment risk.
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.
