What is Fas ligand?
Fas ligand (FasL or CD95L or CD178) is a type-II transmembrane protein that belongs to the tumor necrosis factor (TNF) family. Its binding with its receptor induces apoptosis. Fas ligand/receptor interactions play an important role in the regulation of the immune system and the progression of cancer.
Which cells express Fas ligand?
In particular, FasL is expressed by astrocytes, oligodendrocytes, and macrophages, while Fas is mainly expressed by macrophages, T cells, and oligodendrocytes (69, 70). Several studies have addressed the role of the Fas–FasL system in experimental autoimmune encephalomyelitis (EAE), the murine model of MS (71–75).
How does Fas binding to the Fas death receptor impact apoptosis in the target cell?
Their interaction leads to apoptosis of thymocytes that fail to rearrange correctly their T cell receptor (TCR) genes and of those that recognize self-antigens, a process called negative selection; moreover, Fas–FasL interaction leads to activation-induced cell death, a form of apoptosis induced by repeated TCR …
What does Fas stand for in apoptosis?

What is the Fas pathway?
What is the Fas pathway and its role in cells? The Fas cell signaling pathway has a central role in the physiological regulation of programmed cell death (also called apoptosis) and has been implicated in the pathogenesis of various malignancies and diseases of the immune system.
Where is Fas located?
chromosome 10
FAS receptor gene is located on the long arm of chromosome 10 (10q24. 1) in humans and on chromosome 19 in mice. The gene lies on the plus (Watson strand) and is 25,255 bases in length organized into nine protein encoding exons.
Where is the Fas ligand found?
Fas ligand (FasL) is a type II membrane protein that belongs to the TNF superfamily. It is found in the eye and can induce apoptotic cell death in cells that express Fas. Fas is part of the TNF receptor family and is found on lymphocytes. It is believed that apoptosis is one method of immune privilege in the eye.
Where is FasL found?
What role does the death receptor Fas play in the immune system?
Studies with mutant mice and cells from human patients have shown that FAS plays critical roles in the immune system, including the killing of pathogen-infected cells and the death of obsolete and potentially dangerous lymphocytes. FAS triggers apoptosis through FADD-mediated recruitment and activation of caspase-8.
What cells express Fas receptors?
1 Fas Pathway Fas, which belongs to the TNF-R family, is expressed in lymphoid, myeloid, and nonhematopoietic cell types, while FasL is primarily expressed in CD8+ or activated CD4+ T cells.
What is FAS type?
Fetal alcohol spectrum disorders (FASDs) are a group of conditions that can occur in a person who was exposed to alcohol before birth. These effects can include physical problems and problems with behavior and learning. Often, a person with an FASD has a mix of these problems.

What is a Fas ligand?
From Wikipedia, the free encyclopedia Fas ligand (FasL or CD95 L or CD178) is a type-II transmembrane protein that belongs to the tumor necrosis factor (TNF) family. Its binding with its receptor induces apoptosis. Fas ligand/receptor interactions play an important role in the regulation of the immune system and the progression of cancer.
What is apoptosis and Fas-Fas ligand binding?
Apoptosis triggered by Fas-Fas ligand binding plays a fundamental role in the regulation of the immune system. Its functions include: T-cell homeostasis: the activation of T-cells leads to their expression of the Fas ligand.
What is the CID code for Fas ligand?

What is the role of Fas ligand in allergic encephalomyelitis?
Fas and Fas ligand enhance the pathogenesis of experimental allergic encephalomyelitis, but are not essential for immune privilege in the central nervous system. J Immunol (1997) 159 (7):3096–9. 74. Waldner H, Sobel RA, Howard E, Kuchroo VK.
