Several DcRs have been identified that play a role in the pathogenesis of autoimmune diseases such as DcR3/TR6, interleukin‐1 receptor 2 (IL‐1RII), tumor necrosis factor (TNF)‐related apoptosis‐inducing ligand receptors (TRAIL receptors), soluble TNF receptors (sTNFRs), IL‐18 binding protein (IL‐18BP), vascular endothelial growth factor receptor‐1 (VEGFR‐1), and atypical chemokine receptors (ACKRs) [9]. The gene discussed is TNFRSF6B; the disease is autoimmune disease.
