The hypothesis proposes that maternal immune activation could lead to DNA hypermethylation at the TREM2 promoter, resulting in life‑long TREM2 haploinsufficiency and thereby altering microglial responses to amyloid. However, direct evidence linking maternal immune activation to TREM2 promoter hypermethylation is currently lacking. In contrast, loss‑of‑function studies show that TREM2 deficiency promotes amyloid plaque compaction while increasing neurotoxicity (PMID: 29101263), and TREM2 mutation
**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
