Comparing 2 hypotheses side-by-side
## Molecular Mechanism and Rationale The oligodendrocyte-targeted myelin sulfatide restoration therapy centers on the enzymatic pathway involving cerebroside sulfotransferase (CST) and galactose-3-O-sulfotransferase 1 (GAL3ST1), which catalyze the synthesis of sulfatides—critical lipid components of myelin membranes. CST transfers sulfate groups to galactosylceramide to form 3-O-sulfogalactosylceramide (sulfatide), while GAL3ST1 provides an alternative sulfation pathway for myelin lipid metabol
**Background and Rationale** TREM2 variants represent major genetic risk factors for Alzheimer's disease, with loss-of-function mutations increasing dementia risk threefold. While TREM2 is exclusively expressed on microglia, emerging evidence suggests its primary pathogenic role occurs through disrupted astrocyte-microglia communication rather than intrinsic microglial dysfunction. Healthy brain homeostasis depends on coordinated responses between these glial populations, where TREM2+ microglia
