TNF receptor 2-deficient CD8 T cells are resistant to Fas/Fas ligand-induced cell death.
Apoptotic cell death plays a fundamental role in the maintenance of tissue homeostasis in complex biological systems. It is also a major mechanism for keeping immune reactions in check. Members of the TNF family of receptors and cytokines are implicated in the regulation of apoptotic signals that shape the immune system. In this study, we have examined the role of three members of the TNFR fami...
متن کاملFas receptor and neuronal cell death after spinal cord ischemia.
Cell death from spinal cord injury is mediated in part by apoptotic mechanisms involving downstream caspases (e.g., caspase-3). Upstream mechanisms may involve other caspases such as procaspase-8, a 55 kDa apical caspase, which we found constitutively expressed within spinal cord neurons along with Fas. As early as 1.5 hr after transient ischemia, activated caspase-8 (p18) and caspase-8 mRNA ap...
متن کاملNecrotic Death Pathway in FAS Receptor Signaling
A caspase 8-deficient subline (JB6) of human Jurkat cells can be killed by the oligomerization of Fas-associated protein with death domain (FADD). This cell death process is not accompanied by caspase activation, but by necrotic morphological changes. Here, we show that the death effector domain of FADD is responsible for the FADD-mediated necrotic pathway. This process was accompanied by a los...
متن کاملLysosomes and Fas-mediated liver cell death.
A number of studies, mostly performed ex vivo, suggest that lysosomes are involved in apoptosis as a result of a release of their cathepsins into the cytosol. These enzymes could then contribute to the permeabilization of the outer mitochondrial membrane; they could also activate effector caspases. The present study aims at testing whether the membrane of liver lysosomes is disrupted during Fas...
متن کاملT cell receptor ligation triggers novel nonapoptotic cell death pathways that are Fas-independent or Fas-dependent.
Short-term culture of activated T cells with IL-2 renders them highly susceptible to apoptotic death triggered by TCR cross-linking. Activation-induced apoptosis is contingent upon caspase activation and this is mediated primarily by Fas/Fas ligand (FasL) interactions that, in turn, are optimized by p38 mitogen-activated protein kinase (MAPK)-regulated signals. Although T cells from mice bearin...
