Anti-interleukin-6 agents are a recent class of therapeutics.
New research has found IL-6 to be an anti-inflammatory cytokine with multiple beneficial effects when released by contracting muscle as a myokine. IL-6 had previously been classified as a proinflammatory cytokine. Therefore, it was first thought that the exercise-induced IL-6 response was related to muscle damage. However, it has become evident that eccentric exercise is not associated with a larger increase in plasma IL-6 than exercise involving concentric “nondamaging” muscle contractions. This finding clearly demonstrates that muscle damage is not required to provoke an increase in plasma IL-6 during exercise. As a matter of fact, eccentric exercise may result in a delayed peak and a much slower decrease of plasma IL-6 during recovery.
Anti-IL-6 therapies should therefore take into consideration the (beneficial) anti-inflammatory effects of myokines generally, including the now-established multiple benefits of muscle-derived Interleukin 6.
