Lymphotoxin

Lymphotoxin (pronounced: lim-foh-tox-in), also known as tumor necrosis factor beta (TNF-beta), is a cytokine that plays an essential role in the body's immune response.

Etymology

The term "lymphotoxin" is derived from the words "lymphocyte," a type of white blood cell, and "toxin," referring to a poisonous substance. It was named for its ability to kill certain types of cancer cells in vitro.

Function

Lymphotoxin is produced by lymphocytes and is involved in the body's immune response. It is a member of the tumor necrosis factor (TNF) family, a group of cytokines that stimulate the acute phase reaction. Lymphotoxin aids in the formation of lymph nodes and Peyer's patches, which are essential for the body's defense against pathogens.
