BackgroundTNF-ligand-related molecule 1A (TL1A), is an endothelium-derived T cell costimulator and a ligand for tumor necrosis factor receptor superfamily members DR3 and decoy receptor 3.1 TL1A binds to the death-domain receptor (DR)3 and provides costimulatory signals to activated lymphocytes. Through this interaction, TL1A induces secretion of IFN-γ. Blockade of the TL1A/DR3 pathway may offer therapeutic opportunities in Crohn's disease.2 Protein DetailsPurity >95% by SDS-PAGE and analyzed by silver stain. Endotoxin Level <0.1 EU/µg as determined by the LAL method Biological Activity Measured by its ability to induce apoptosis of TF‑1 human erythroleukemic cells.3 The ED50 for this effect is 15-75 ng/mL.
