Persistence of Th17/Tc17 Cell Expression upon Smoking Cessation in Mice with Cigarette Smoke-Induced Emphysema
Increased numbers of IL- (Th17) cells and IL- T (Tc17) cells are not reversible after smoking cessation.Lung single-cell from nonsmoke mice, smoke-exposed mice, and smoke cessation mice was stimulated by PMA and ionomycin for 4 h and analyzed IL-17A by using flow cytometry. (a) Representative FACS staining for IL-17A in gated T cells. (b) Representative FACS staining for IL-17A in gated T cells. (c) The frequencies (%) of Th17 cells; (d) the frequencies (%) of Tc17 cells. Results are expressed as % (mean SEM). animals/group; *.
