Several novel interleukin (IL)-10-related cytokines have recently been discovered. These include IL-22, IL-26, and the interferon-lambda (IFN-lambda) proteins IFN-lambda1 (IL-29), IFN-lambda2 (IL-28A), and IFN-lambda3 (IL-28B). The ligand-binding chains for IL-22, IL-26, and IFN-lambda are distinct from that used by IL-10; however, all of these cytokines use a common second chain, IL-10 receptor-2 (IL-10R2; CRF2-4), to assemble their active receptor complexes. Thus, IL-10R2 is a shared component in at least four distinct class II cytokine-receptor complexes. IL-10 binds to IL-10R1; IL-22 binds to IL-22R1; IL-26 binds to IL-20R1; and IFN-lambda binds to IFN-lambdaR1 (also known as IL-28R). The binding of these ligands to their respective R1 chains induces a conformational change that enables IL-10R2 to interact with the newly formed ligand-receptor complexes. This in turn activates a signal-transduction cascade that results in rapid activation of several transcription factors, particularly signal transducer and activator of transcription (STAT)3 and to a lesser degree, STAT1. Activation by IL-10, IL-22, IL-26, or IFN-lambda can be blocked with neutralizing antibodies to the IL-10R2 chain. Although IL-10R2 is broadly expressed on a wide variety of tissues, only a subset of these tissues expresses the ligand-binding R1 chains. The receptors for these cytokines are often present on cell lines derived from various tumors, including liver, colorectal, and pancreatic carcinomas. Consequently, the receptors for these cytokines may provide novel targets for inhibiting the growth of certain types of cancer.
