Abstract

Several epigenetic factors, such as excessive consumption of calories through fast food, reduced fiber intake and sedentary lifestyle, and psychosocial factors, including the decrease in sleep duration and depression are contributing to the increasing incidence of diabetes mellitus type 2 both in Brazilian population as the world. Whereas diabetic patients had a worsened prognosis inflammatory installed and that the infection is recognized as a possible cause of morbidity and mortality in these patients, this project aims to investigate the role of neutrophils, cells that act on the first line of defense in our body, in the inflammatory response using an experimental model of type 2 diabetes mellitus. For this purpose, cellular functions will be evaluated, such as: cell death, phagocytic capacity, myeloperoxidase activity, production of reactive oxygen species, production/liberation of cytokines, components of NADPH oxidase and the expression of genes involved with the inflammatory response per se as those related to the essential functions of neutrophils.
