Figure 2. Memantine suppressed oxygen-glucose deprivation/reperfusion-induced expression and secretions of proinflammatory cytokines in human umbilical vein endothelial cells (HUVECs). Cells were treated with memantine (5, 10 μM) for 6 h, followed by exposure to oxygen-glucose deprivation (6 h)/reperfusion (24 h) (OGD/R). (A) mRNA levels of IL-6 and IL-8; (B). Secretions of IL-6 and IL-8 (####, P<0.0001 vs. vehicle group; ***, *****, P<0.001, 0.0001 vs OGD/R group).
