ABSTRACT
Objective To investigate the effects of upadacitinib on the polarization and inflammation of BV2 microglia after oxygen glucose deprivation/recovery (OGD/R) and to explore its mechanism of action. Methods The experiment was divided into 3 groups: control group, OGD group and upadacitinib treatment group. After BV2 cells were treated with OGD/R, MTT was used to detect cell survival rate. Wound scratch assay was used to detect the cell migration ability. qPCR was used to detect mRNA levels of M1-type polarization markers (CD11b, CD32, iNOS) and M2-type polarization markers (Arg-1, IL-10, CD206) of BV2 cells. ELISA was used to detect the levels of IL-1β, IL-6, and TNF-α in the culture medium. Western blot was used to detect the expression levels of JAK1/STAT6 pathway-related proteins. Results Upadacitinib increased the survival of BV2 cells after OGD/R (P<0.05), reduced the polarization of BV2 cells to M1 type (P<0.05). Upadacitinib significantly decreased the migration ability of BV2 cells induced by OGD/R (P<0.05), reduced the inflammatory factors secreted by BV2 cells induced by OGD/R: IL-1β, IL-6, TNF-α (P<0.05). Upadacitinib increased the survival rate of co-cultured PC12 cells (P<0.05). Upadacitinib significantly inhibited the expression levels of p-JAK1 and p-STAT6 proteins in BV2 cells activated by OGD/R induction (P<0.05). Conclusion Upadacitinib decreases polarization of BV2 induced by OGD/R to M1 type and reduces inflammation, which is related to JAK1/STAT6 pathway.
