The term of apoptosis, programmed cell death, was firstly coined to distinguish with necrosis, pathologic cell death, by Kerr in 1972. Although various pathogenic factors are able to occur apoptosis, ti is essential process for normal development and physiology in the animals. Recently in the field of medicine, apoptosis researeh is especially focused in serveral Kind of pathopoiesis problems including cancer, immunodeficiency associated HIV and other virus, autommunity, alzheimer and congenital anormality. The information obtained from the animal model system for apoptosis should be directly applicable to both life science for understanding of development and medicine for practical the rapy. To know the common mechanism of apoptosis, it is prerequisite that the genes and factors responsible for apoptosis should be defined and characterized on the molecular level. The study of apoptosis should contribute largely to biology inculuding cell physiology and development, and both basic and clinical medicine to understand cause of diseases for therapy as well as congenital defect.
