NEAT1_v2 hypermethylation (m6A) in aging neurons disrupts paraspeckle scaffolding, trapping TDP-43 in the nucleus and exacerbating ALS/FTD pathology. NEAT1_v1/v2 nomenclature is imprecise, m6A modifications typically affect RNA stability not protein scaffolding, and TDP-43 mislocalization is downstream not proximal. m6A editing tools are nascent and technically ambitious.
**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
