<p>-</p>, <p>Trem2 p.T66M</p> Trem2em1Bwef Mixed DBA/2J, FVB/ N, C57BL/6J Trem2 TREM2 T66M A CA>TG substitution was introduced into the murine Trem2 gene using CRISPR/Cas9 genome editing, resulting in a threonine-to-methionine substitution at amino acid 66.. Trem2: Knock-In Frontotemporal Dementia Age-related microglial activation seen in wild-type mice is absent in homozygotes. No data. Reduced cerebral blood flow and reduced cerebral glucose metabolism in homozygotes. Bone marrow-derived macrophages from heterozygous and homozygous Trem2 T66M mice show reduced proliferation, survival, and phagocytosis.
