Recent experimental data have provided associations between ambient PM2.5 (fine particulate matter; diameter ≤ 2.5 μm) and propensity to inflammation and chronic diseases especially among susceptible groups, such as elderly people. There is cumulative evidence that type-2 diabetes mellitus is a chronic inflammatory state aggravated by factors that promote endothelium inflammation. Accordingly our hypothesis that the exposure of aged obese population to PM2.5 might aggravate type-2 diabetes, we used a model of aged, diet-induced obese mice. C57BL6 male mice were fed with regular chow (n=30; RC) or high-fat chow (n=36; HF) during one-year and randomly assigned to filtered (FA-RC, n=16; FA-HF, n=19) or PM2.5 concentrated air (600 μg.m-3) (EXP-RC, n=14; EXPHF, n=17) chambers to have a daily 1 hour exposition dur..
