Microglia mainly control the immune efficiency of the central nervous system and play an important role in various psychiatric diseases. Neuroinflammation triggered by the signaling pathway activation is related to the development of depression. Microglia are the main mediators of neuroinflammation. Different stimulations promote the polarization of microglia, which secrete inflammatory cytokines that affect the regulation of neuroinflammation. Clinical and experimental research in vivo and in vitro have demonstrated the relationship of depression with neuroinflammation mediated by microglial polarization. The possible mechanisms of polarization mediating depression involve NF-κB signaling pathway activation, respiratory bursts, complement receptor 3 (CR3) signaling pathway activation, NLRP3 inflammation activation, cannibalism receptor 1 (CB1) activation, Notch-1 signal pathway stimulation, and PPARγ receptor activation. This review discusses research progress on the relationship between microglial polarization and depression.
