Background
TheInterleukin-6 receptor (IL-6R) consists of an 80-kDa IL-6 binding protein (αchain) (CD126) and gp130. The alpha-chain CD126 is a glycoprotein that containsthe ligand-binding site. The human IL-6R protein contains 468 amino acids,which includes a signal peptide, an extracellular region, a transmembranedomain, and a short cytoplasmic domain of 19, 339, 28, and 82 amino acids,respectively. IL-6R are present on several types of tumor cells, includingmultiple myeloma, hepatocellular carcinoma, prostate carcinoma , and epidermoidcarcinoma. The IL-6/IL-6R signal pathway promotes the tumor growth in variouscancers, especially for glioma. Hence, IL-6R not only can be used as a targetsite for transporting drugs, but also as a therapeutic site. Primary humancartilage cells express IL-6R, which is further induced in the presence ofIL-6. This makes cartilage cells direct targets or effectors of IL-6.
