TDP-43 pathological inclusions colocalize with mitochondria, co-aggregating mitochondrial genome maintenance and ETC mRNAs. This disrupts mitochondrial dynamics, reduces ATP production, increases ROS, and causes bioenergetic failure disproportionately affecting high-energy-demand processes like neurotransmission and memory consolidation.
**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
