Two principal modes of cell death are now recognized, namely necrosis and apoptosis. Both may follow cell injury but the nature of the two types of death are quite different. Mode # 1. Cell Necrosis: The changes in cells undergoing necrosis are essentially a continuation of those described above, in cell injury. However, they are, of course, more profound and [...]
After reading this article you will learn about the process of apoptosis which is characterised by chromatin condensation, with the help of suitable diagrams. Apoptosis, the programmed cell death is characterized by chromatin condensation and cell shrinkage in the early stage and then the nucleus and cytoplasm fragment, forming membrane-bound apoptotic bodies which can be engulfed by phagocytes. In contrast, [...]
In this article we will discuss about:- 1. Introduction to Apoptosis 2. Cellular Events of Apoptosis 3. Mechanism 4. Importance. Introduction to Apoptosis: Every normal living cell of animals, plants and even bacteria are mortal. I.e., they must die after some time. Cell death is a finely tuned programme inherent in the cells genetic machinery. This normal cell death which [...]
