tumor necrosis factor receptor superfamily member 25 (TNFRSF25), also known as death receptor 3 (DR3) TNFRSF25 (also known as death receptor 3 (DR3), death domain receptor 3 (DDR3), apoptosis-mediating receptor, lymphocyte associated receptor of death (LARD), apoptosis inducing receptor (AIR), APO-3, translocating chain-association membrane protein (TRAMP), WSL-1, WSL-LR or TNFRSF12) is preferentially expressed in thymocytes and lymphocytes, and may play a role in regulating lymphocyte homeostasis. It has been detected in lymphocyte-rich tissues such as colon, intestine, thymus and spleen, as well as in the prostate. Various death domain containing adaptor proteins mediate the signal transduction of this receptor; it activates nuclear factor kappa-B (NFkB) and induces cell apoptosis by associating with TNFRSF1A-associated via death domain (TRADD), which is known to mediate signal transduction of tumor necrosis factor receptors. DR3 associates with tumor necrosis factor (TNF)-like cytokine 1A (TL1A also known as TNFSF15) on activated lymphocytes and induces pro-inflammatory signals; TL1A also binds decoy receptor DcR3 (also known as TNFRSF6B). DR3/DcR3/TL1A expression is increased in both serum and inflamed tissues in autoimmune diseases such as in several autoimmune diseases, including inflammatory bowel disease (IBD), rheumatoid arthritis (RA), allergic asthma, experimental autoimmune encephalomyelitis, type 1 diabetes, ankylosing spondylitis (AS), and primary biliary cirrhosis (PBC), making modulation of TL1A-DR3 interaction a potential therapeutic target. |
