Fas and Fas ligand (FasL) are implicated in programmed cell death or apoptosis. In the immunological field, they are particularly important in auto-immunity, graft rejection and anti-tumoral response. Fas ligand expression on thymocytes, activated T lymphocytes, and in sites of immune privilege, suggests the importance of Fas/FasL interactions in negative control of the immune response. The recent description of FasL expression by tumoral cells, represents a new mechanism of immune escape for different cancer, and has been well studied in colon adenocarcinoma.
