Reelin from GABAergic basket cells maintains intrinsic theta-nested grid firing and suppresses Aβ-induced mitochondrial fragmentation. Age-related decline in Reelin removes a critical neurotrophic signal that normally suppresses GSK-3β and maintains AMPAR trafficking. Loss of Reelin creates a permissive state for amyloid and tau pathology specifically in layer II. However, Reelin decline could be secondary to neuronal dysfunction, and grid cell impairment may simply reflect layer II neuron loss
**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
