Biochem/physiol Actions

Lymphotoxin-α (LT-α), also known as tumor necrosis factor-β (TNF-β), and lymphotoxin-β (LT-β) are members of the TNF family. Secreted LT-α complexes with the membrane-associated LT-β to generate two types of heterotrimers, LTα1/β2 and LTα2/β1. The predominant membrane-bound heterotrimer LTα1/β2 binds and activates only to the lymphotoxin β receptor (LT-βR). The other heterotrimer LTα2/β1 binds and activates TNF RI, TNF RII, and LT-βR. LT is critical for normal lymphoid organ development. LT is expressed by activated naive CD4 cells, unpolarized IL-2-secreting effectors, and Th1 effector cells.

Mutations in LTA (lymphotoxin-α) are associated with myasthenia gravis.
