Apoptosis as a conserved pathway Intrinsic and extrinsic pathways of apoptosis What is the difference between intrinsic and extrinsic pathway of apoptosis? There are at least two broad signaling pathways that lead to apoptosis: the intrinsic pathw...
when conditions in the extracellular environment determine that a cell must die. The intrinsic pathway of apoptosis pathway begins when an injury occurs within the cell and the resulting stress activates the apoptotic pathway. In both the intrins...
The extrinsic pathway begins outside a cell, when conditions in the extracellular environment determine that a cell must die. The intrinsic apoptosis pathway begins when an injury occurs within the cell. The injury could result in necrosis and produce an inflammatory response, but the apoptotic ...
Molecular pathways of apoptosis Two principle pathways Extrinsic pathway Intrinsic pathway (1) Extrinsic pathway: Fas Signaling Pathway Fas (also called Apo-1 or CD95) is a member of the tumor necrosis factor receptor (TNFR) superfamily. Receptor-mediated pathway of apoptosis Bcl-2 Family(...
In these instances, the number and degree of apoptotic reactions are so great that the resulting cell remains cannot be completely removed. This leads to an increased excretion of fibrogenic mediators that could be responsible for increased proliferation of fibroblasts in spite of the increased ...

The apoptotic response of cells can be induced by the intrinsic and the extrinsic pathway, the former being mediated by the mitochondria and the latter activated by ligand stimulation of death receptors at the cell surface [1]. Death receptor ligands such as tumor necrosis factor-related apoptosis...
ARC with its CARD binds to death receptors, Fas, FADD and pro-caspase-8 and inhibits the assembly of DISC, thus abrogating the extrinsic apoptotic signaling. In the extrinsic pathway of apoptosis, ARC can directly bind and inhibit caspase-8 [3], whereas in the intrinsic pathway, ARC interac...
