Project description:<p>Exercise enhances physical performance and reduces the risk of many disorders such as cardiovascular disease, type 2 diabetes, dementia and cancer. Exercise characteristically incites an inflammatory response, notably in skeletal muscles. While some effector mechanisms have been identified, regulatory elements activated in response to exercise remain obscure. Here, we have addressed the roles of Foxp3+CD4+ regulatory T cells (Tregs) in the healthful activities of exercise via immunologic, transcriptomic, histologic, metabolic and biochemical analyses of acute and chronic murine exercise models. Exercise rapidly induced expansion of the muscle Treg compartment, thereby guarding against over-exuberant production of interferon gamma and consequent metabolic disruptions, particularly mitochondrial aberrancies. Importantly, the performance-enhancing effects of exercise training were dampened in the absence of Tregs. Thus, exercise is a natural Treg booster with therapeutic potential in disease and aging contexts.</p>

Project description:Understanding the relationship between physical exercise, reactive oxygen species and skeletal muscle modification is important in order to better identify the benefits or the damages that appropriate or inappropriate exercise can induce. Heart and skeletal muscles have a high density of mitochondria with robust energetic demands and mitochondria plasticity has an important role in both cardiovascular system and skeletal muscle responses. The aim of this study was to investigate the influence of regular physical activity on oxidation profiles of mitochondrial proteins from heart and tibialis anterior muscles. To this end, we used mouse as animal model. Mice were divided in two groups: untrained and regularly trained. The carbonylated protein pattern was studied by two-dimensional gel electrophoresis followed by Western Blot with anti-dinitrophenyl hydrazone antibodies. Mass spectrometry analysis allowed the identifications of several different protein oxidation sites including methionine, cysteine, proline and leucine residues. A large number of oxidized protein were found in both untrained and trained animals. Moreover, mitochondria from skeletal muscles and heart showed almost the same carbonylation pattern. Interestingly, exercise training seems to increase carbonylation level mostly of mitochondrial protein from skeletal muscle.

Project description:Acute physical exercise elicits changes in gene expression in skeletal muscles to promote metabolic changes and to repair exercise-induced muscle injuries. Here, we investigated the impact of a single bout of running exercise until exhaustion on global transcriptional profiles in porcine skeletal muscles. Using a combined microarray and candidate gene approach, we identified a suite of genes that are differentially expressed in muscles during post-exercise recovery. Thus, several members of the heat shock protein family and proteins associated with proteolytic events were significantly up-regulated, suggesting that protein breakdown, prevention of protein aggregation and stabilization of unfolded proteins are important processes for restoring cellular homeostasis. We also detected an up-regulation of genes, which have been reported to be associated with muscle cell proliferation and differentiation, possibly reflecting an activation, differentiation and fusion of satellite cells to facilitate repair of muscle damage. In addition, exercise increased expression of the nuclear hormone receptors, which regulates metabolic functions associated with lipid, carbohydrate and energy homeostasis. Finally, we observed an unanticipated involvement of long non-coding RNA transcripts, which have been implicated in RNA processing and nuclear retention of adenosine-to-inosine edited mRNAs. These findings expand the complexity of pathways affected by acute contractile activity of skeletal muscle, contributing to a better understanding of the molecular processes that occur in muscle tissue in the recovery phase.

Project description:Exercise is a salubrious activity: it enhances physical performance and reduces the risk of modern afflictions such as cardiovascular disease, type 2 diabetes, and cancer. Exercise characteristically incites an inflammatory response, notably in skeletal muscles. While some key innate and adaptive effector immunocytes have been identified, counteracting regulatory elements remain obscure. We have addressed the roles of Foxp3+CD4+ regulatory T cells (Tregs) in the healthful activities of exercise via immunologic, transcriptomic, histologic, metabolic, and biochemical analyses of acute and chronic exercise models. Exercise rapidly induced expansion of the muscle Treg compartment, thereby guarding against over-exuberant production of interferons and consequent metabolic disruptions, particularly mitochondrial aberrancies. Importantly, typical performance enhancements resulting from exercise training were dampened in the absence of Tregs. Thus, exercise is a natural Treg booster with therapeutic potential in disease and aging contexts.
