Eosinophils deficiency alleviated ER stress in the lungs of Af-exposed mice. a, b Representative immunofluorescence photomicrographs of lung tissues showing the expression and localization of GRP78 (magnification, 200×) and the quantified mean fluorescence intensity. Data are mean ± SEM (n = 3–5). c–e mRNA levels of ATF4, GRP78, and CHOP in the lung tissues. f, g The proteins levels of GRP78 and CHOP in the lungs were analyzed by Western blots. Values for qPCR were normalized to β-actin. Data are mean ± SEM. (n = 4–5). *p < 0.05, **p < 0.01, and ns = no significance
