Comparing 2 hypotheses side-by-side
## **Molecular Mechanism and Rationale** The oligodendrocyte-targeted myelin sulfatide restoration therapy operates through a sophisticated molecular mechanism centered on the enzymatic cascade governing sulfatide biosynthesis within oligodendrocyte membranes. Cerebroside sulfotransferase (CST), encoded by the GAL3ST1 gene, represents the rate-limiting enzyme responsible for converting galactosylceramide (GalCer) to 3-O-sulfogalactosylceramide (sulfatide) through the transfer of sulfate groups
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.
This summary checks where the selected hypotheses point toward the same target or mechanism, and where they pull in opposite directions.
