ABSTRACT
Interleukin-6 (IL-6) is a spreading pleiotropic cytokine, with both anti-inflammatory and proinflammatory effects. It not only participates in the body immune responses but also is involved in the biological regulative processes among different organs, tissues, and cells. IL-6 has both anti-inflammatory and pro-inflammatory effects. In the early stage of pathogen infection, IL-6 plays an anti-inflammatory role in the body, and its level is moderately increased in the body to resist inflammation and maintain internal homeostasis. However, a large amount of IL-6 release can cause excessive inflammation and trigger other pathological changes in the body. Il-6 also has the dual effect of stimulating the synthesis and degradation of skeletal muscle protein in regulating skeletal muscle mass. As an important locomotive organ, skeletal muscle is also one of the key targets of IL-6. IL-6 takes part in the biological control of skeletal muscle hypertrophy through regulating muscle satellite cell proliferation and differentiation under specific stresses. In addition IL-6 is also associated with skeletal muscle atrophy induced by aging and other pathological stresses. In addition, during exercise stress, skeletal muscle can also serve as an endocrine organ to secrete and release IL-6 that facilitates the "crosstalk" between skeletal muscle and other organs or tissues. As IL-6 plays as a versatile role in our body, this paper reviews the research progress of the mechanism of IL-6 in the regulation of skeletal muscle mass, which may provide theoretical support for revealing the molecular mechanism of skeletal muscle stresses and adaptations.
