•DOCK2 silence protects against cerebral ischemia/reperfusion injury.•Loss of DOCK2 enhances M2 polarization and inhibits M1 polarization of microglia.•DOCK2 knockdown activates the STAT6 signaling pathway. Cerebral ischemia/reperfusion is the major pathophysiological process in stroke and could lead to severe and permanent disability. The current study aimed to investigate the effects of dedicator of cytokinesis 2 (DOCK2) on cerebral ischemia/reperfusion-induced cerebral injury. We established a mouse middle cerebral artery occlusion (MCAO) model with suture-occluded method in vivo. Then, BV-2 cells were conducted to oxygen-glucose deprivation and re-oxygenation (OGD/R) in vitro. The results showed that DOCK2 was highly expressed in ischemic brain following MCAO and in BV-2 cells induced by OGD/R. DOCK2 depletion protected against MCAO-induced brain infarcts and neuron degeneration. DOCK2 downregulation improved long-term neurological function, which was assessed by the Morris water-maze test. Moreover, silencing of DOCK2 promoted M2 polarization (anti-inflammation) and repressed M1 polarization (pro-inflammation) of microglia both in vivo and in vitro. Subsequently, we found that the loss of DOCK2 upregulated the expression of p-STAT6. DOCK2 knockdown-induced microglial cell polarization towards M2 phenotype was partly abrogated by the STAT6 inhibitor AS1517499. In conclusion, DOCK2 downregulation protected against cerebral ischemia/reperfusion by modulating microglia polarization via the activation of the STAT6 signaling pathway.
