[FAS ligand is a TNF family, type II transmembrane protein expressed on many cell types and secreted from T-cells upon TCR ligation by MHC/peptide complexes residing on antigen presenting cells. FAS ligand triggers cell death by binding to the cell surface receptor FAS, another transmembrane protein member of the TNF receptor family. FAS ligand is expressed in activated splenocytes and thymocytes, consistent with its involvement in T-cell-mediated cytotoxicity, and in the liver, lung, ovary, and heart, where its function is unclear.
