Where this comes from

Abstract

The role of the cytokine interleukin-6 (IL-6) in metabolic homeostasis is the subject of conjecture. Recent work in Nature Medicine (Ellingsgaard et al., 2011) demonstrates that IL-6 released from skeletal muscle during exercise mediates crosstalk between insulin-sensitive tissues, intestinal L cells, and pancreatic islets to adapt to changes in insulin demand.
