Programmed cell death is a normal physiological process in which cells in our body die in a programmed and controlled way. It is also known as apoptosis or cell suicide. There are several synonyms for programmed cell death, including regulated cell death, controlled cell death, and coordinated cell death. These terms describe the same process of cell death that occurs in a programmed and controlled manner. Other related terms include intrinsic apoptosis, extrinsic apoptosis, and necroptosis. These synonyms are commonly used in biomedical research, where understanding the mechanisms of cell death is important for developing therapies for diseases such as cancer and autoimmune disorders.
