IL‐22 induces Tyr phosphorylation of STAT3. (A) Vero E6 cells were treated with IL‐22 from 0 to 90 min. Cellular proteins were sampled every 15 min. Western blotting was performed using anti‐phospho STAT3 (Tyr and Ser) antibodies. (B) SARS‐CoV‐infected Vero E6 cells were treated with IL‐22 for 20 min at 18 h.p.i., and then, Western blot analysis was performed using anti‐phospho STAT3 (Tyr) and anti‐phospho p38 MAPK.
