Abstract:
Apoptosis or programmed cell death is the physiologic, natural form of cell death, exhibiting characteristic morphological and biochemical features. Apoptosis occurs upon developmental processes and represents an important defense mechanism. Defective apoptosis can result in a variety of diseases. Rapidly growing knowledge upon this mode of cell death, especially the identification of genes involved in the regulation of apoptosis raise the hope for new therapies in the treatment of cancer, autoimmune and neurodegenerative disorders, as well as viral infections.
