OPTN serves as the primary autophagy receptor for damaged mitochondria in neurons via its LC3-interacting region. TBK1 phosphorylates OPTN at S177, enhancing its affinity for ubiquitinated mitochondrial proteins. ALS-causing mutations impair this phospho-regulation, causing accumulation of dysfunctional mitochondria specifically in motor neurons with high energy demands. Strong convergence of ALS genetics but specificity claim challenged.
**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
