IL27RA

IL-27R alpha (Interleukin 27 receptor alpha) is a subunit of the interleukin-27 receptor, an inflammatory cytokine that possesses extensive immunological functions[1]. IL-27Rα is specific for IL-27 and is primarily expressed on the cell surface of inflammatory cells, including T, B, and NK lymphocytes, neutrophils, monocytes, and mast cells, although it is found at lower levels in macrophages, hepatocytes, keratinocytes, and endothelial cells. IL-27R alpha can be used as a natural IL-27 antagonist[1].IL-27Rα (WSX-1) and gp130 compose the IL-27 receptor-signaling complex. Binding of IL-27 to its heterodimeric receptor complex leads to the intracellular recruitment and activation of the Janus kinase (JAK)/STAT-1 and STAT-3 pathways, suppress the expression of inflammatory cytokines. IL-27R alpha can be used as a natural IL-27 antagonist[1]. IL-27R alpha can be used as an independent prognostic aGVHD biomarker[2]. IL-27/IL-27RA signaling can suppress the expression of inflammatory cytokines, IL-6 and IL-8, induced by LPS stimulation, leads to phosphorylation of STAT1 and STAT3[3].
