In order to explore the roles of astrocytes in post-stroke inflammation, the levels of inflammatory factors were detected in primary astrocytes at 0 h, 6 h, 12 h, 24 h, and 48 h after 6-h OGD, including TNF-α, IL-6, IL-10, inducible nitric oxide synthase (iNOS), IL-1β, and CXCL10 (Fig. 1, Table 1). Here, NOS2 is linked to Stroke.
