Interleukin-6 (IL-6) is a member of the IL-6 family, which consists of polypeptide cytokines with a four–α-helix structure and a molecular mass of 21 to 28 kDa.
Re: Interleukin-6
The molecular cloning of the cDNAs encoding B cell stimulatory factor 2 (BSF-2), interferon β2, and 26 kDa protein showed that all these molecules are identical. Furthermore, hybridoma/plasmacytoma growth factor (HPGF) and hepatocyte-stimulating factor (HSF) were also found to be identical to this molecule and, therefore, this molecule has been called IL-6.
