CD95, also known as FAS or Apo-1, is a member of the tumor necrosis factor receptor superfamily (TNFR) and is found on the surface of many normal and neoplastically transformed cells. Its ligand, CD95L (FASL/Apo-1L), is able to induce apoptosis in CD95-expressing cells upon binding. CD95 and CD95L are up-regulated on lymphocytes upon activation and are known to play a key role in the regulation of an inflammatory response: Juxtocrine “fratricide” of neighbouring lymphocytes via mutual CD95 and CD95L expression helps to terminate immune responses, while apoptosis of pro-inflammatory cells via CD95 helps maintain immune privilege in sites such as the eye, where CD95L is found to be expressed in the retina and cornea. Cross-linking of CD95 receptors by DX2 monoclonal antibody has been described to induce apoptosis in certain target cells.
