This hypothesis proposes that the TREM2-dependent microglial senescence transition can be tracked and predicted through a novel composite biomarker index combining plasma p-tau217/CSF neurogranin ratio with microglial senescence markers. As TREM2 signaling undergoes age-related dysfunction, transitioning from neuroprotective to neurotoxic, this shift triggers a cascade of molecular changes detectable in peripheral and central biofluid compartments. The composite index captures three critical dim
**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
