Hypoxia-preconditioned olfactory mucosa mesenchymal stem cells abolish cerebral ischemia/reperfusion-induced pyroptosis and apoptotic death of microglial cells by activating HIF-1α

Figure 7. Knockdown of HIF-1α in OM-MSCs exacerbated cerebral OGD/R-induced pyroptosis in BV2 microglial cells under hypoxic conditions. (A, B) Expression of NLRP3, ASC, pro-caspase1, cleaved-caspase1, pro-caspase8, cleaved-caspase8 and GSDMD in BV2 microglial cells were quantified by Western blotting analysis. (C, D) Level of IL-1β and IL-18 in BV2 microglial cells were measured by ELISA. (E) The levels of LDH activity in BV2 microglial cells was determined by ELISA. All data are presented as the mean value ±SD. *p<0.05; **p<0.01, ***p<0.001, compared with vector group.
