A role for apoptosis-inducing factor in T cell development
Apoptosis-inducing factor (Aif) is a mitochondrial flavoprotein that regulates cell metabolism and survival in many tissues. We report that aif-hypomorphic harlequin (Hq) mice show thymic hypocellularity and a cell-autonomous thymocyte developmental block associated with apoptosis at the β-selection stage, independent of T cell receptor β recombination. No abnormalities are observed in the B ce...
متن کاملRole of apoptosis-inducing factor (Aif) in the T cell lineage
Multiple checkpoints regulating finely balanced death-versus-survival decisions characterize both thymic development and peripheral homeostasis of T lymphocytes. While exploring the mechanisms of T cell death involved at various stages during the life of a T cell, we have observed and reported a variety of non-redundant roles for apoptosis inducing factor (Aif), a mitochondrial flavoprotein. Ai...
متن کاملTumor necrosis factor-related apoptosis-inducing ligand in T cell development: sensitivity of human thymocytes.
TRAIL (tumor necrosis factor-related apoptosis-inducing ligand) is a recently identified member of the tumor necrosis factor cytokine superfamily. TRAIL has been shown to induce apoptosis in various tumor cell lines, whereas most primary cells seem to be resistant. These observations have raised considerable interest in the use of TRAIL in tumor therapy. Yet little is known about the physiologi...
متن کاملCritical Role for Tumor Necrosis Factor–related Apoptosis-inducing Ligand in Immune Surveillance Against Tumor Development
Natural killer (NK) cells and interferon (IFN)-gamma have been implicated in immune surveillance against tumor development. Here we show that tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) plays a critical role in the NK cell-mediated and IFN-gamma-dependent tumor surveillance. Administration of neutralizing monoclonal antibody against TRAIL promoted tumor development in mice s...
متن کاملApoptosis-inducing factor
Although the seminal paper by Kerr, Wyllie and Currie (Kerr et al., 1972), who coined the word ‘apoptosis’, stated that only nuclei but not cytoplasmic organelles would undergo major modifications in the dying cell, recent evidence suggests that no cellular compartment is spared (Ferri and Kroemer, 2001). Mitochondria are particularly affected early during the apoptotic process, and they are no...
