Several signaling pathways are involved in apoptosis, with the two main pathways being the intrinsic (mitochondrial) pathway and the extrinsic (death receptor) pathway.

Dec 23, 2025 · Study the intricate machinery of the apoptosis signaling pathway. Click here to learn more and gain insights into programmed cell death mechanisms.

Dec 18, 2023 · During apoptosis, a cascade of caspase activation mediates signal transduction and cellular destruction, whereas pyroptosis occurs when activated caspases cleave …

Weak external signals may also activate the intrinsic pathway of apoptosis. [7] Both pathways induce cell death by activating caspases, which are proteases, or enzymes that degrade …

In the initiation stage of programmed cell death, the cell receives a signal that activates the apoptosis pathway, either from internal stresses or extracellular triggers. In the execution …

Apoptosis is a regulated cellular suicide mechanism, which is initiated either through a specific class of death receptors or intrinsic factors such as DNA damage and is driven by caspase …
