Exposure to inhaled DEP and high-fat diet increases circulating LPS. Mean circulating LPS A significantly increases in C57Bl/6 male mice exposed to diesel exhaust particles (DEP- 35 μg PM) or saline control (CON) twice a week for four weeks on either low-fat (LF) or high-fat (HF) diet. Data are depicted as ± SEM with *p < 0.05 compared to LF + CON, †p < 0.05 compared to LF + DEP, and ‡p < 0.05 compared to HF + CON by two-way ANOVA
