Abstract

Human adenovirus 36 (Ad-36) causes obesity with increased adiposity, in contrast, Ad-36 infection reduces glucose and lipid metabolism; the results, however, are not consistent. In the current study, the effects of Ad-36 infection on glucose and lipid profile and inflammatory markers in Wistar rats were investigated. Sixty male Wistar rats were randomly divided into infected and control groups. Ad-36 virus suspension was injected in the experimental group rats. Blood samples were collected in the beginning and after 12 weeks in both groups. After 12 weeks, a significant improvement was observed in fasting blood glucose, fasting serum insulin, insulin sensitivity, serum triglycerides and total cholesterol in the infected group compared with the non-infected groups. There were no significant differences in inflammatory biomarkers including tumor necrosis factor-α, interleukin 6 and monocyte chemoattractant protein-1 levels between infected and control groups. This study showed that Ad-36 had favorable effects on glycemic and lipid control in infected rats, but inflammatory biomarker levels were similar for 2 groups. Ad-36 infections could potentially be a new way to develop novel antidiabetic and antihyperlipidemic therapeutic agents.
