Western blots in infected NPTr cells in presence or absence of chemical inhibitor. Western blots for phospho-ERK1/2 (pERK1/2), phospho-p38 (pp38) and phospho-JAK2 (pJAK2) in newborn porcine trachea (NPTr) cells infected with H3N2 SIV at 30 min in presence or in absence of chemical inhibitors UO126 (ERK1/2), SB202190 (p38), and JAK inhibitor (JAK Inhibitor I). The control group was cultured in presence of DMSO, data are represented as means ± SEM, (n = 3). Results are representative of three independent experiments. Different letters indicate significant differences (one way ANOVA, P < 0.05) as compared to control (without inhibitor and virus).
