Layer II stellate cells exhibit theta-burst firing that chronically elevates intracellular Ca²⁺ via Cav3.2 channels, activating calpains and impairing proteasome function while priming mitochondrial permeability transition pore opening. This creates a bioenergetic-proteostatic vicious cycle that accelerates tau hyperphosphorylation preferentially in these neurons. The therapeutic angle is compelling: ethosuximide (FDA-approved) is in Phase II trials (NCT05856231), providing near-term translation
**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
