Abstract
Muscle is the target of immunological injury in several muscle diseases. It is important therefore to understand the immunological capabilities of muscle cells themselves. Although it is conventional to discuss the effects of the immune system on other cells, tissues or organs, the system’s boundaries cannot be sharply drawn, and in an increasing number of ways, the immunological capabilities of non‐immune tissues are recognized as determining the course of immune‐inflammatory processes. Muscle cells have an inherent ability to express and respond to a variety of immunologically relevant surface molecules, cytokines, and chemokines under inflammatory conditions. The ability of muscle cells to process and present antigens to the immune cells is currently debated; thus, this review is aimed at examining the immunological capabilities of skeletal muscle cells in vitro and in vivo.
