LTA (lymphotoxin alpha) or TNFB (tumor necrosis factor beta) is a member of the tumor necrosis factor superfamily (TNFSF1). LTA/TNFSF1 is a cytokine produced by lymphocytes. LTA is highly inducible, secreted, and forms heterotrimers with LTB/TNFSF3 (lymphotoxin-beta), which anchor LTA/TNFSF1 to the cell surface. LTA/TNFSF1 also mediates a large variety of inflammatory, immunostimulatory, and antiviral responses, is involved in the formation of secondary lymphoid organs during development and plays a role in apoptosis. Genetic variations in the LTA gene are associated with susceptibility to leprosy type 4, myocardial infarction, non-Hodgkin's lymphoma, and psoriatic arthritis.
