TDP-43 aggregates sequester hepatocyte growth factor-regulated tyrosine kinase substrate (HGS), a critical hub coordinating early endosome-to-autophagosome cargo delivery. In motor neurons where TDP-43 nuclear loss and cytoplasmic aggregation occurs early in ALS, HGS is functionally depleted, creating specific vulnerability where upstream autophagy induction cannot compensate for downstream cargo recognition failure. This hypothesis survived critique due to its mechanistic specificity for motor
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.
