Apoptosis is a cell suicide mechanism that enables metazoans to control cell number in tissues and to eliminate individual cells that threaten the animals survival. Certain cells have unique sensors termed death receptors on their surface. Death receptors detect the presence of extracellular death signals and in response they rapidly ignite the cells intrinsic apoptosis machinery.
Death receptorscell surface receptors that transmit apoptosis signals initiated by specific death ligandsplay a central role in instructive apoptosis. These receptors can activate death caspases within seconds of ligand bind-ing causing an apoptotic demise of the cell within hours. Signaling and modulation - PubMed Result.

Two types of death receptors signaling and modulation complexes The first group comprises the Death-Inducing Signaling Complexes DISCs that are formed at the Fas receptor TRAILR1 or.
The second group comprises the TNFR1 DR3 DR6 and EDAR. Modulation of Death Receptor signaling There are several levels of modulation of DR signaling French and Tschopp 2003. As mentioned above decoy receptors can compete with DRs for ligand binding and FLIP blocks procaspase-8 activation at the DISC.
Further downstream IAPs inhibitors of apoptosis inhibit effector caspase activation. A Receptor-bound FADD forms a death-inducing signaling complex DISC with caspase-8 as well as with caspase-10 in human cells. The amount of caspase-8 activity generated in type I.
The TNF receptor-associated factor TRAF family is a group of adapter proteins that link a wide variety of cell surface receptors. Including the TNF and IL-1 receptor superfamily to diverse signaling cascades which lead to the activation of NF-kappaB and mitogen-activated protein kinases. In addition TRAFs interact with a variety of proteins that regulate receptor-induced cell death or survival.

The study of death receptor DR signaling has led to the discovery of new signaling paradigms including the first example of direct receptor-mediated activation of a. The term death receptor refers to those members of the TNF receptor superfamily that contain a death domain such as TNFR1 Fas receptor DR4 and DR5.
They were named after the fact that they seemed to play an important role in apoptosis programmed cell death although they are now known to play other roles as well. Tumour necrosis factor-related apoptosis-inducing ligand or Apo2 ligand TRAILApo2L is a member of the tumour necrosis factor TNF superfamily of cytokines that induces apoptosis upon binding to its death domain-containing transmembrane receptors death receptors 4 and 5 DR4 DR5. Importantly TRAIL preferentially induces apoptosis in cancer cells while exhibiting little or no toxicity.
Modulation of death receptors whose cleavage of cellular substrates leads to apoptosis. The death receptors involved in the extrinsic apoptotic pathway belong to the TNF receptor superfamily that include Fas CD95 or Apo1 TNFR1 DR3 DR4 TRAILR1 DR5 TRAILR2 and DR62 These receptors are characterized.
