Human TL1A/TNFSF15 OneStep ELISA Kit

Human TL1A (also known as TNFSF15) is a cytokine belonging to the tumor necrosis factor (TNF) superfamily, primarily expressed by vascular endothelial cells, macrophages, and dendritic cells. It functions by binding to its cognate receptor DR3 (Death Receptor 3) on activated T cells and innate lymphoid cells, delivering a potent co-stimulatory signal that strongly enhances the production of interferon-gamma and other inflammatory cytokines. This signaling axis plays a crucial role in amplifying and sustaining immune responses, particularly in mucosal tissues such as the intestines. Genetic studies have firmly established that variants in the TNFSF15 gene are significant risk factors for the development of chronic inflammatory bowel diseases, including Crohn's disease and ulcerative colitis. Beyond gut inflammation, TL1A is implicated in the pathogenesis of other autoimmune and inflammatory conditions, such as rheumatoid arthritis and psoriasis. Given its central role in driving pathogenic inflammation, the TL1A/DR3 pathway has emerged as a highly promising therapeutic target, with several neutralizing antibodies and inhibitors currently under clinical investigation.
