A wide variety of protein and non-protein ligands, including lipids and DNA, can bind to TREM2, inducing the activation of microglia via DAP12. Both Trem2 and Dap12 have been identified as causative genes for Nasu-Hakola disease, which causes presenile dementia in association with bone cysts. Furthermore, TREM2/DAP12 signaling represents an essential inducer of the activated microglial phenotype in neuronal diseases, including Alzheimer's disease. Therefore, most previous studies examining TREM2/DAP12 have focused on their roles in microglia under pathological conditions. However, a growing body of evidence has demonstrated the involvement of TREM2/DAP12 signaling in the regulation of physiological functions in microglia. Accordingly, by examining the importance of TREM2/DAP12 in the regulation of microglial activity during development, homeostasis, and aging in the brain, this review elucidates the roles played by this complex in the healthy brain.}, title = {Non-pathological roles of microglial TREM2/DAP12: TREM2/DAP12 regulates the physiological functions of microglia from development to aging}, volume = {141}, year = {2020} }
