MeCP2 and REST-mediated repression of miR-132/212 in aging neurons creates a feed-forward hypermethylation cycle silencing synaptic plasticity genes (Arc, Bdnf exon IV, Creb). The REST mechanism has internal contradictions (REST deficiency would increase neuronal gene expression) and requires reformulation. miR-132 agomir development is ongoing, making this a viable biomarker and therapeutic target with correction.
**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
