UNLABELLED
Exercise increases muscle derived Interleukin–6 (IL–6) leading to insulin secretion via glucagon-like peptide–1. IL–1 antagonism improves glycemia and decreases systemic inflammation including IL–6 in patients with type 2 diabetes. However, it is not known whether physiological, exercise-induced muscle-derived IL–6 is also regulated by the IL–1 system. Therefore we conducted a double blind, crossover study in 17 healthy male subjects randomized to receive either the IL–1 receptor antagonist IL-1Ra (anakinra) or placebo prior to an acute treadmill exercise. Muscle activity led to a 2–3 fold increase in serum IL–6 concentrations but anakinra had no effect on this exercise-induced IL–6. Furthermore, the IL–1 responsive inflammatory markers CRP, cortisol and MCP–1 remained largely unaffected by exercise and anakinra. We conclude that the beneficial effect of muscle-induced IL–6 is not meaningfully affected by IL–1 antagonism.
