Background
Interleukin-10 Receptor alpha (IL-10 R alpha ), also known as IL-10 R1, is a 90-110 kDa transmembrane glycoprotein member of the class II cytokine receptor family (1). IL-10 R alpha is required for mediating the effects of IL-10, a critical molecule in the control of microbial infections, allergic and autoimmune inflammation, and cancer (2-5). Whereas human IL-10 is active on mouse cells, mouse IL-10 does not act on human cells (6). IL-10 R alpha is the ligand specific subunit of the IL-10 receptor complex. Noncovalent dimers of IL-10 bind to IL‑10 R alpha , resulting in the recruitment of IL-10 R beta (6-8). IL-10 R beta is a ubiquitously expressed transmembrane protein that does not bind IL-10 by itself but is required for signal transduction and in vivo IL-10 responsiveness (7, 9). IL-10 R beta also associates with IL-20 R alpha , IL-22 R alpha , or IL-28 R alpha to form the receptor complexes for IL-22, IL-26, IL-28, and IL-29 (1). Immunosuppressive signal transduction through the IL-10 receptor complex can be inhibited by activation of TLR2, 4, or 9, enabling strengthened immune responses during infection (10). Polymorphisms of human IL-10 R alpha may limit viral immune evasion by retaining full responsiveness to human IL-10 but responding weakly to the cytomegalovirus homolog of IL-10 (11). Mature human IL-10 R alpha consists of a 214 amino acid (aa) extracellular domain (ECD), a 21 aa transmembrane segment, and a 322 aa cytoplasmic domain (12). Within the ECD, human IL-10 R alpha shares 59% aa sequence identity with mouse and rat IL-10 R alpha .
