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.

Hypothesis 1: Integrated stress response transcription factors ATF4 and DDIT3/CHOP suppress MAPT indirectly by reprogramming neuronal transcription toward proteostasis and amino-acid stress genes, pos...
Skeptic
Hypothesis 1 is attractive because ISR factors often dominate proteotoxic transcription, but indirect repression is hard to assign cleanly. If ATF4 or CHOP perturbation changes MAPT only modestly whil...
