Apoptosis: A form of cell death in which a programmed sequence of events leads to the elimination of cells without releasing harmful substances into the surrounding area. Apoptosis plays a crucial role in developing and maintaining the health of the body by eliminating old cells, unnecessary cells, and unhealthy cells.
Apoptosis is essential for normal development and proceeds by the extrinsic death receptor pathway, or the intrinsic Bclâ2 blockable pathway. Both pathways activate a class of proteases termed caspases that cleave intracellular substrates resulting in cell death.
