CHMP2B is specifically involved in late endosomal sorting of ubiquitinated cargo while CHMP2A handles essential cytokinesis. Selective CHMP2B inhibition may theoretically spare essential ESCRT functions. ASSESSED AS FALSIFIED: CHMP2B knockout causes progressive neurodegeneration in vivo, directly contradicting therapeutic premise.
**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
