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.[1] It is also known to be required for normal development of Peyer's patches.[2]
Lymphotoxin is homologous to Tumor Necrosis Factor beta, but secreted by T-cells. It is paracrine due to the small amounts produced. The effects are similar to TNF-alpha, but TNF-beta is also important for the development of lymphoid organs.
