Apoptosis is an active process of programmed cell death. Fas is a cell-surface protein which is expressed on activated lymphocytes and known as CD95, TNFRSF6 or APO-1. Fas-L is ligand of Fas and known as CD95 LG or TNFSF6. Apoptosis or cell death is a result of binding of Fas-L to Fas which is expressed on the surfaces of these cells. Cancer cells escape this binding by overexpression of Fas-L ...
Autoimmune lymphoproliferative syndrome is frequently caused by mutations in genes involved in the Fas death receptor pathway, but for 20-30% of patients the genetic defect is unknown. We observed that treatment of healthy T cells with interleukin-12 induces upregulation of Fas ligand and Fas ligand-dependent apoptosis. Consistently, interleukin-12 could not induce apoptosis in Fas ligand-defic...
We wondered whether the apoptosis known to occur after UV-B irradiation might involve the Fas/Fas ligand (FasL) signaling pathway. We exposed PBLs from normal individuals, and also the Jurkat (E6-1) and U937 cell lines, to graded doses of UV-B irradiation and observed a prompt and marked increase in Fas expression at doses as low as 0.5 mJ/cm2. Increased Fas expression did not require new prote...
OBJECTIVES To examine whether the Fas/Fas ligand system is involved in the pathogenesis of acute myocardial infarction (AMI), we measured the levels of the soluble form of the Fas ligand (sFasL) in the plasma of patients with AMI and stable or unstable angina pectoris (AP). BACKGROUND The Fas ligand (FasL) is rapidly cleaved off by a metalloproteinase from the cell membrane to become a solubl...
Fas ligand (FasL) is a death factor that induces apoptosis in cells bearing its receptor, Fas. Fas and FasL have been detected in the vessel wall, and it has been proposed that Fas-mediated apoptosis has a role in physiological and pathological cell turnover in the vasculature. Here, we evaluated the expression of Fas in the presence and absence of cytokines on both endothelial cells (ECs) and ...
Recent evidence has emphasized the importance of apoptosis in the maintenance of tissue homeostasis and the pathogenesis of malignant and immune diseases. Autoimmune thyroid diseases such as Hashimoto's thyroiditis and Graves' disease, as well as other autoimmune endocrine diseases, have been associated with dysregulation of apoptotic signaling pathways. In particular, dysfunction of the Fas ap...
The Fas/Fas ligand (Fas-L) system has been established as one of the regulatory pathways of apoptotic cell death. Fas is a type I membrane protein which belongs to the tumour necrosis factor/nerve growth factor receptor family and mediates apoptosis. A soluble form of Fas (sFas) found in sera of human subjects is thought to block apoptosis by inhibition of binding between Fas and the antibody t...
