| Programmed cell death (PCD) or apoptosis, an active process of cell death, plays a central role in normal tissue development and organogenesis, as well as in the pathogenesis of different diseases. Although it occurs in diverse cells and tissues under the influence of a remarkable variety of inducing agents, the resultant ultrastructural and biochemical changes are extremely monotonous, indicating the existence of a common biological mechanism underlying its occurrence. It is generally accepted that a developmental program leading to cell death cannot be advantageous to unicellular organisms and that PCD appeared in evolution to fulfill the organizational needs of multicellular life. However, the recent description of apoptotic death occurring in three... |
