Detailed explanation-1: -Apoptosis maintains the constancy of cell number in an organism. The unwanted cells are eliminated from the body by apoptosis. The dangerous T-lymphocytes are eliminated by apoptosis. Programmed cell death is crucial for cell development.
Detailed explanation-2: -(A-pop-TOH-sis) A type of cell death in which a series of molecular steps in a cell lead to its death. This is one method the body uses to get rid of unneeded or abnormal cells. The process of apoptosis may be blocked in cancer cells. Also called programmed cell death.
Detailed explanation-3: -It is generally accepted that there are two major pathways of apoptotic cell death induction: extrinsic signaling through death receptors that leads to the formation of the death-inducing signaling complex (DISC), and intrinsic signaling mainly through mitochondria which leads to the formation of the apoptosome.
Detailed explanation-4: -Apoptosis: is a form of cell death that prevents immune activation. Apoptotic cells have a particular microscopic appearance. The cell activates proteins called caspases that are normally dormant. These caspases dismantle the cell from within.
Detailed explanation-5: -Apoptosis is a regulated cellular suicide mechanism characterized by nuclear condensation, cell shrinkage, membrane blebbing, and DNA fragmentation. Caspases, a family of cysteine proteases, are the central regulators of apoptosis.
