During early disease phases, neurons tolerate partial propagation inhibition; the therapeutic window is wide. Biomarker-defined staging (NfL, p-tau217) identifies patients within the open window. Functions as a clinical development framework rather than direct therapeutic target.
**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
