Comparing 2 hypotheses side-by-side
## Molecular Mechanism and Rationale The oligodendrocyte DNA repair enhancement therapy is predicated on emerging evidence that white matter pathology, particularly oligodendrocyte dysfunction, represents an early and potentially causative event in Alzheimer's disease neurodegeneration. Oligodendrocytes exhibit heightened vulnerability to oxidative stress due to their high metabolic demands for myelin production and maintenance, coupled with relatively low antioxidant capacity. This vulnerabili
**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
