pFTY720 attenuates oxygen‐glucose deprivation (OGD)‐induced inflammation in astrocytes through PI3K/NF‐κB signalling pathway. (A) Representative immunoblots of phosphorylated PI3K and nuclear NF‐κB in astrocytes; the levels of the phosphorylation of PI3K (B) and nuclear NF‐κB (C) determined by Western blotting. *P < .05 vs Con group; #P < .05, ###P < .001 vs OGD group; $$P < .01 vs OGD plus pFTY720 pre‐treatment group. Results are shown as mean ± SEM. in every 4 independent experiments. OGD: oxygen‐glucose deprivation; pFTY720: phosphorylated FTY720
