Background and Rationale
The delicate balance between neuronal excitation and inhibition (E/I balance) represents a fundamental organizing principle of cortical microcircuits, and its disruption has emerged as a critical pathophysiological feature across neurodegenerative disorders, including Alzheimer's disease (AD). Parvalbumin-expressing (PV) interneurons constitute approximately 30-40% of all cortical GABAergic neurons and serve as the primary mediators of fast-spiking, feedforward and feed
**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
