Abstract

In experimental models, hypothalamic inflammation is an early and determining factor in the installation and progression of obesity. Pharmacological and gene-based approaches have proven efficient in restraining inflammation and correcting the obese phenotypes. However, the role of aerobic physical training in the modulation of hypothalamic inflammation is little-known. The consumption of a high-fat diet activates the expression or the activity of inflammatory responsive proteins such as SOCS3, IKK, JNK, iNOS and TLR4 which impair leptin and insulin signaling in the hypothalamus, thus, disrupting the main satietogenic and adipostatic routes that maintain a stable body mass. In addition, new evidence showed that the high-fat diet activates hypothalamic IKK²/NF-ºB, at least in part, through elevated endoplasmic reticulum stress in the hypothalamus and that these phenomena are associated also with central insulin and leptin resistance, hyperphagia and body weight gain in animals. Instead, exercise has long been reported to reduce body weight and visceral adiposity, increasing the energy expenditure and improving glycaemic control in overweight or diabetes type 2 patients. Thus, the main aim of the present study is to verify the role of effect of physical training to prevent the inflammation and apoptosis in hypothalamic cells of obese mice fed with a high-fat diet
