Biotinylated LILRA5/CD85f/ILT11 Protein

Quality Statement:
Leukocyte immunoglobulin-like receptor A5 (LILRA5) belongs to a family of receptors known to regulate leukocyte activation, which encoded within the leukocyte receptor cluster (LRC) on human chromosome 19. LIRs are transmembrane proteins containing either two or four extracellular immunoglobulin domains, and most family members are expressed predominantly on myeloid cell lineages. Cross-linking of LILRA5 on monocytes induced production of pro-inflammatory cytokines, suggesting that LILRA5 plays a role in inflammation. Furthermore, LILRA5 induced selective production of pro-inflammatory cytokines as well as IL-10. LILRA5 mRNA and protein expression was tightly regulated by TNF-α, IL-10 and IFN-γ. Increased expression of LILRA5 in rheumatoid tissue, together with its ability to induce key cytokines involved in RA, suggests that this novel receptor may contribute to disease pathogenesis.
