Exposure to diesel exhaust particles results in increased collagen deposition surrounding the bronchioles. a Representative images of lung tissue sections stained with Masson’s trichrome in C57Bl/6 wildtype mice on either control (LF) or high-fat (HF) diet exposed to either saline (control) or diesel exhaust particles (DEP – 35 μg PM) twice a week for a total of 30 days. Blue areas indicate collagen deposition. b Graph of histology scoring of Masson’s trichrome staining. 20x magnification, scale bar = 240 μm. Data are depicted as mean ± SEM with *p < 0.05 compared to LF Control, ‡p < 0.05 compared to LF DEP by two way ANOVA
