• •Microglia play key role in the occurrence, development and outcome of ischemic cerebrovascular disease.•Gastrodin has a dual effect on microglia with oxygen-glucose deprivation.•The dual role of Gastrodin is closely related to the MAPK signal transduction pathway.•Gastrodin may be a new drug for the clinical treatment of ischemic cerebrovascular disease. Cerebrovascular disease is one of the major diseases that seriously harm human health currently. The purpose of this study is to find an effective treatment and clarify its mechanism of action to provide a new idea and drug target for the clinical treatment of ischemic cerebrovascular disease. The microglia cell line (BV2 cell line) was cultured in vitro. Prepare a hypoxia ischemia cell model by OGD and simulate the pathophysiological process of ischemic cerebrovascular disease in vivo. According to the techniques of LDH Cytotoxicity Assay Kit, flow cytometry of Annexin V-FITC Apoptosis Detection Kit, Laser Confocal Fluorescence Immunostaining (Double staining method), enzyme-linked immunosorbent assay (ELISA), and Western blotting, BV2 cells are observed through morphology and function changes induced by OGD. Moreover, these techniques were used to analyze changes in key proteins expression of signal transduction pathway in ischemic cerebrovascular disease, to explore the mechanism of gastrodin on ischemic cerebrovascular disease, and to elucidate the available ways for cell protection following ischemia and hypoxia. Gastrodin has no obvious toxic effect on BV-2 cells under physiological conditions. The death rate of BV-2 cells increases as the time of hypoxia increase. In the absence of oxygen, Gastrodin has a protective effect on the survival of BV-2 cells. This protective effect is related to the reduction of apoptosis rate. It can also improve the hypoxic tolerance of BV-2 cells, and there is no obvious Gastrodin dose-dependence. Moreover, Gastrodin has dual effects on BV-2 cells. The dual role of Gastrodin is closely related to the expression of several proteins which can affect the MAPK signal transduction pathway. Gastrodin has a dual effect on microglia with OGD. On the one hand, Gastrodin can inhibit the inflammatory cytokines secreted by microglia and aggravate the inflammatory response; on the other hand, Gastrodin can promote the secretion of protective cytokines from microglia to reduce the inflammatory response.
