TLDR
Fas ligand (FasL), a cell surface molecule belonging to the tumor necrosis factor family, binds to its receptor Fas, thus inducing apoptosis of Fas-bearing cells.Abstract:
Fas ligand (FasL), a cell surface molecule belonging to the tumor necrosis factor family, binds to its receptor Fas, thus inducing apoptosis of Fas-bearing cells. Various cells express Fas, whereas FasL is expressed predominantly in activated T cells. In the immune system, Fas and FasL are involved in down-regulation of immune reactions as well as in T cell-mediated cytotoxicity. Malfunction of the Fas system causes lymphoproliferative disorders and accelerates autoimmune diseases, whereas its exacerbation may cause tissue destruction.read more

Apoptosis by death factor.
TL;DR: This work was supported in part by Grants-in-Aid from the Ministry of Education, Science, and Culture of Japan and by a Research Grant from the Princess Takamatsu Cancer Research Fund, and performed in part through Special Coordination Funds of the Science and Technology Agency of the Japanese Government.

TL;DR: It is reported here that, except for cells of the macrophage lineage, normal human tissues do not express B7-H1 and the findings have implications for the design of T cell–based cancer immunotherapy.

The TNF and TNF receptor superfamilies: integrating mammalian biology.
TL;DR: The authors regret the inability to cite all of the primary literature contributing to this review due to length considerations, but wish to thank F. Chan, T. Migone, and J. Wang for insightful comments on the manuscript.

TL;DR: A caspase-activated deoxyribonuclease (CAD) and its inhibitor (ICAD) have now been identified in the cytoplasmic fraction of mouse lymphoma cells and seems to function as a chaperone for CAD during its synthesis, remaining complexed with CAD to inhibit its DNase activity.

TL;DR: This work utilized nano-electrospray tandem mass spectrometry to identify CAP3 and CAP4, components of the CD95 (Fas/APO-1) death-inducing signaling complex, and found a novel 55 kDa protein, designated FLICE, which has homology to both FADD and the ICE/CED-3 family of cysteine proteases.

Programmed cell death and the control of cell survival: lessons from the nervous system
TL;DR: This neurotrophic strategy for the regulation of neuronal numbers may be only one example of a general mechanism that helps to regulate the numbers of many other vertebrate cell types, which also require signals from other cells to survive.
Journal ArticleDOI
A novel domain within the 55 kd TNF receptor signals cell death.
TL;DR: Alanine-scanning mutagenesis of TNF-R1 confirmed that many of the amino acids conserved with Fas antigen are critical for the cytotoxic signal and is likely to define a novel domain (death domain) that signals programmed cell death.

Lpr and gld: single gene models of systemic autoimmunity and lymphoproliferative disease.
TL;DR: The autosomal recessive lpr and gld genes induce in mice multiple autoantibodies and the progressive accumulation of large numbers of non-malignant CD4- CD8- T lymphocytes, and the mechanism whereby these two genes induce autoimmunity and lymphoproliferation remains obscure.

Apoptosis and Programmed Cell Death in Immunity
TL;DR: In the immune system there are many examples of programmed cell death, during development of lymphocytes as well as at later stages, after interaction with antigen, which display the morphology of apoptosis.

TL;DR: Levels of soluble Fas were elevated in patients with systemic lupus erythematosus, and mice injected with soluble Fas displayed autoimmune features.
