Protein levels of Interleukin- (IL-) 17 and Interleukin-21 (IL-21) in lungs and peripheral blood of air- and CS-exposed mice at 24 weeks by using ELISA. (a) Protein levels of IL-17 in lungs, (b) protein levels of IL-21 in lungs, (c) protein levels of IL-17 in peripheral blood, and (d) protein levels of IL-21 in peripheral blood. Results are expressed as pg/mL (mean ± SD). 𝑛=10 animals/group; *𝑃<0.001.
