It occurs via two main pathways: the Extrinsic and the Intrinsic pathways. The Extrinsic Pathway is triggered by external signals, where death receptors on the cell surface bind to specific ligands, leading to the activation of caspases that dismantle the cell. This pathway plays a pivotal role in the immune system's ability to destroy harmful cells. On the other hand, the Intrinsic Pathway, also known as the mitochondrial pathway, is initiated from within the cell in response to stress signals, such as DNA damage or oxidative stress. This pathway involves the release of cytochrome c from mitochondria, which then forms a complex with Apaf-1 and procaspase-9, ultimately activating the caspase cascade leading to cell death. Both pathways are essential for maintaining the balance between cell survival and death, with implications in disease processes, including cancer and neurodegeneration.
