apoptosis

[‚ā·pō′tō·səs]
(cell and molecular biology)
Death of cells triggered by extracellular signals or genetically programmed events, carried out by processes within the cell, and characterized by systemic breakdown of cellular constituents, in particular chromosomal deoxyribonucleic acid; may be involved in normal development and aging, or may serve to eliminate defective or damaged cells. Also known as programmed cell death.

One of the major mechanisms of sepsis-induced immunosuppression is due to apoptosis of the cells of the adaptive immune system (5).
Apoptosis es una forma controlada de muerte celular que sirve como mecanismo regulador de diversos procesos biologicos.
The fragments were fixed, embedded in paraffin, and cut into serial 5-[micro]m-thick sections that were used for confirmation of the diagnosis, immunohistochemistry for the detection of TNF-[alpha], IFN-[gamma], Bcl-2, Fas, and iNOS, and detection of apoptosis by the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) technique.
Programmed death is the feature that distinguishes apoptosis from the accidental death of necrosis.
Aegera has taken this technology to the clinic with an antisense therapeutic, AEG35156, targeting just one of their IAPs named the X-linked inhibitor of apoptosis (XIAP) protein, a target which inhibits apoptosis using duel mechanisms.
An advantage of this test is that it measures cellular material released into the circulation by dying or dead cancer cells as a result of apoptosis.
In vitro apoptosis in individual cells was determined by terminal desoxyriboxyl-desoxyriboxyl transferase-mediated DVTP nick-end labeling (TUNEL) assay with the In Situ Cell Death Assay Kit (Roche Diagnostic Corp.

Quite distinctive from necrosis is a second method of cell death, apoptosis, which is a highly regulated and systematic form of programed cell death [8, 9].
first generation indirect apoptogens (established drugs such as cytotoxics which have turned out to rely on apoptosis for part of their efficacy)
Apoptosis is a recognized mechanism for the elimination of redundant cells, although it may also inhibit cell proliferation.
In a process called apoptosis, many damaged or no-longer-needed cells kill themselves.
