From: IL-22 inhibits bleomycin-induced pulmonary fibrosis in association with inhibition of IL-17A in mice
IL-22 decreases the production of IL-17A. A In the bleomycin-induced pulmonary fibrosis model, lung tissues were collected at day 7 and day 21. qPCR was used to detect mRNA (n = 6) levels of IL-17A and IFN-γ. B Flow cytometry was used to analyze the proportion of Th17 cells in lung tissues (n = 4) at day 7 and day 21 after bleomycin administration. Data are mean ± SEM, compared using one-way ANOVA test. *, P < 0.05
