Motor neurons exhibit uniquely high cytosolic calcium dynamics due to sustained synaptic input and action potential firing, creating a 'calcium-primed' state where mitochondrial calcium overload preferentially triggers mPTP opening at lower TDP-43 burden. TDP-43 pathology may disrupt mitochondrial calcium buffering capacity, directly linking cytosolic burden to mitochondrial dysfunction. MCU deletion protects against excitotoxicity, demonstrating the pathway's centrality. However, MCU is widely
**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
