Expressions of several typical inflammatory factors in primary astrocytes after OGD. a–f The primary cultural astrocytes were harvested 0 h, 6 h, 12 h, 24 h, and 48 h after OGD for 6 h. RT-PCR was used to detect the mRNA levels of TNF-a, IL-6, IL-10, iNOS, IL-1b, and CXCL10. The mRNA of all these cytokines were elevated in 6 h after ischemia (P < 0.05) and decreased after 24 h
