The effects of PM exposure on the key molecular events in the lungs of DIO and T1D mice. Representative images of F4/80 immunochemical staining (scale bar, 50 μm) (A) and corresponding quantitative results (D). Representative images of 4HNE immunofluorescence staining (scale bar, 50 μm) (B) and corresponding quantitative results (F). Representative images of SA-β-gal staining (scale bar, 50 μm) (E) and corresponding quantitative results (G). Representative images of CCSP immunofluorescence staining (scale bar, 50 μm) (D) and corresponding quantitative results (H) (All n = 5). The data are presented as mean ± SEM. ^*P < 0.05 (PM vs. AF); ^#P < 0.05 (DIO vs. ND); ^&P < 0.05 (T1D vs. ND); ^$P < 0.05 (T1D vs. DIO).
