Abstract:
Death Receptor 3 (DR3) and its cognate ligand TL1A belong to the tumor necrosis factor superfamily (TNFSF). This sophisticated network of receptor-ligand systems controls innumerable biological processes. For many (if not all) TNFSF ligands and receptors, a role in conditions such as inflammation, tissue development, proliferation, and cell death has been firmly established. However, relatively little is known about DR3 and TL1A. Here, we review novel aspects of DR3 signaling and DR3-associated signaling pathways before summarizing the function of DR3 in the immune system. The emerging role of DR3 in disease will be addressed before we finally critically discuss the potential therapeutic exploitation of this receptor-ligand pair.

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
