GLP-1 secretion is regulated by IL-6 signalling: a randomised, placebo-controlled study

IL-6 is a cytokine with various effects on metabolism. In mice, IL-6 improved beta cell function and glucose homeostasis via upregulation of glucagon-like peptide 1 (GLP-1), and IL-6 release from muscle during exercise potentiated this beneficial increase in GLP-1. This study aimed to identify whether exercise-induced IL-6 has a similar effect in humans. In a multicentre, double-blind clinical trial, we randomly assigned patients with type 2...
