Lymphotoxin (previously known as tumor necrosis factor-beta) is a lymphokine cytokine.It is a protein that is produced by Th1 type T-cells and induces vascular endothelial cells to change their surface adhesion molecules to allow phagocytic cells to bind to them. It is also known to be required for normal development of Peyer’s patches. Lymphotoxin is homologous to Tumor Necrosis Factor beta but secreted by T-cells.
