Persistence of Th17/Tc17 Cell Expression upon Smoking Cessation in Mice with Cigarette Smoke-Induced Emphysema

Figure 2

Elevated levels of interleukin (IL)-8, TNF-𝛼, and IFN-γ are not reversible after smoking cessation. Protein levels of IL-8, TNF-𝛼, and IFN-γ in BALF of nonsmoke mice, smoke-exposed mice, and smoke cessation mice were measured by using ELISA. (a) Protein levels of IL-8 in BALF, (b) protein levels of TNF-𝛼 in BALF, (c) protein levels of IFN-γ in BALF. Results are expressed as pg/mL (mean ± SEM). 𝑛=10 animals/group; *𝑃<0.001.
