IL-6 Family & Receptor Background

Interleukin-6 (IL-6) family of cytokines includes IL-6, IL-11, leukemia inhibitory factor (LIF), oncostatin M (OSM), ciliary neurotrophic factor (CNTF), cardiotrophin-like cytokine (CLC) and cardiotrophin-1 (CT-1). The IL-6 family cytokines exhibit a four-helix bundle structure. In addition, the receptors of the IL-6 family cytokines share a receptor subunit, which explains one of the mechanisms of functional redundancy. Members of the IL-6 family cytokines utilize one or both of the shared receptor signal transducing subunits, gp130 and LIF receptor (LIFR). IL-31 has also been placed in IL-6 family due to its four-helix bundle structure. IL-6 family binding of gp130 activates the JAK/STAT signaling pathway. Cytokines belonging to the IL-6 family function in many biological processes. IL-6 and IL-16 receptor have been implicated in prostate cancer progression.

Leptin, the ob (obese) gene product, has a structure similar to that of the IL-6 family of cytokines. Furthermore, its receptor (Ob-R) is homologous to gp130. Both Janus kinases and signal transducers and activators of transcription are involved as downstream components of leptin and IL-6 signaling, which demonstrates several similarities between leptin and the IL-6 family.
