IFN-α exposure and IAV infection induce TRIM22 expression in A549 cells. (A) A549 cells were exposed to increasing doses of IFN-α for 20 h. (B) A549 cells were infected with A/NewCaledonia/20/99 (H1N1) at an MOI of 5. TRIM22 mRNA levels (upper) and protein expression (lower) were evaluated 24 h postexposure and were compared to those of mock-treated cells.
