Background

Fas Ligand (FasL), also known as CD178, CD95L, or TNFSF6, is a transmembrane protein homotrimer that binds to Fas/CD95 and triggers apoptosis in the Fas-expressing cell. Fas Ligand also binds the soluble decoy receptor DcR3. It is expressed on activated Th1 cells, CD8+ cytotoxic T cells, and NK cells. A soluble form can be released which remains trimeric and retains the ability to bind Fas. Fas Ligand-induced apoptosis plays a central role in the development of immune tolerance and the maintenance of immune privileged sites. Tumor cells can evade immune surveillance by up-regulating Fas Ligand to kill tumor infiltrating lymphocytes. In mice, a Fas Ligand point mutation is the cause of severe lymphoproliferation and systemic autoimmunity.
