Details

The proinflammatory cytokine IL-6 is one of the most important mediators in the regulation of the immune response, hematopoiesis, and inflammation [1]. It plays roles in chronic inflammation, autoimmune diseases, and cancer. In addition, it has been reported to be involved in the cytokine storm triggered by the corona virus disease 2019 (COVID-19) [2].
 

IL-6 exerts its action by first binding to the IL-6 receptor (IL-6R). The complex of IL-6 and IL-6R associates with the signal-transducing membrane protein gp130, thereby inducing its dimerization (figure 1). This leads to the downstream activation by phosphorylation of certain tyrosine kinases within the Janus family (JAK1, JAK2, and Tyk2). Subsequently, activated JAKs induce phosphorylation, dimerization and translocation of the signal transducer and activator of transcription 3 (STAT3) to the nucleus where it binds enhancer elements of IL-6 inducible genes [3]. Considering the various properties of this pleiotropic cytokine, the IL-6–STAT3 signaling axis is now considered a major target for the treatment of inflammatory diseases [2].
