The Role of FasL and TNF in the Homeostatic Regulation of Immune Responses
The Fas/APO-1 protein (CD95) is expressed on a wide variety of cells and tissues, including monocytes, myelocytes, activated or transformed lymphocytes, thymus, liver, ovary and heart1. It is a member of the TNF receptor/nerve growth factor receptor family of cell-surface receptors2–4. Early studies had indicated that ligation of this receptor in mAb resulted in the death of certain transformed cell lines via a process known as apoptosis5, 6 This process is characterized by cytoplasmic condensation, plasma membrane convolution, nuclear condensation and DNA fragmentation7.
