Background

DcR3 (Decoy Receptor 3), also known as TR6 and TNFRSF6B is a 35-40 kDa secreted member of the TNF Receptor superfamily (1). Mature cynomolgus DcR3 contains four tandem TNFR cysteine-rich domains and shares 92% amino acid sequence identity with human DcR3. It binds to the TNF superfamily ligands Fas Ligand, TL1A, and LIGHT (2-5) and interferes with their respective interactions with Fas, DR3, or HVEM and Lymphotoxin beta R (2-4). It blocks apoptosis triggered through either Fas Ligand, TL1A, or LIGHT (2, 3, 5, 6). DcR3 is up-regulated in a variety of cancers and enhances tumor cell immune evasion (2, 3, 7). It also promotes immune suppression by inducing dendritic cell apoptosis (8), inhibiting NK cell and CD8+ T cell activity (2, 4), and inhibiting the production of inflammatory cytokines during viral infection or autoimmunity (9, 10). In humans, proteolytic removal of the C-terminal 53 amino acids generates a shortened DcR3 that retains the ability to block LIGHT but not Fas Ligand induced apoptosis (11). DcR3 can also induce osteoclast formation from monocytes (12).
