Motor neuron mitochondria exhibit uniquely fragmented cristae with wider cristae junctions due to continuous fission-fusion dynamics at the NMJ, exposing mtDNA nucleoids to mPTP-mediated release. While mechanistically plausible, motor neuron-specific cristae architecture has not been directly demonstrated by comparative EM studies. The hypothesis is strongest as a mechanistic assay tool rather than a near-term therapeutic target. OPA1, DRP1, and mitochondrial dynamics modulation carry risks to h
**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
