Interactions between skeletal muscle and the immune system. A major project in our lab concerns the pathophysiology of muscular dystrophy (dystrophinopathy). Our research has shown that the immune system plays an important role in influencing the severity of muscular dystrophy, and that immune-based interventions can significantly reduce dystrophic muscle pathology and promote muscle regeneration. Our continuing efforts are directed toward identifying the key effector cells and molecules involved in influencing the course of the disease, and examining the interplay between those effectors. Our technical approaches include the generation and analysis of transgenic, dystrophic mice so that the effects of increased or decreased expression of selected effector molecules can be assessed. We also examine the systemic effects of experimental depletions of selected immune cell populations and the efficacy of selected, pharmaceutical interventions on the progress of the disease. In other studies, we are studying the mechanisms through which the immune system influences the wasting of skeletal muscle that occurs during aging, a process called sarcopenia. We are particularly interested in identifying the mechanisms through which specific populations of myeloid cells affect muscle wasting and regeneration, and identifying strategies to slow the wasting process.
