In some cases, one factor can come to the fore, and the rest are just a background for the development of this pathology. Starvation atrophy – This type of atrophy is due to lack of food and using stored food. The decreased blood flow will also activate the renin-angiotensin-aldosterone system, because the kidney will think the blood pressure is low in the whole body. It has no known effect on function, and is described as being expected or normal in aging. Regarding atrophy and hypertrophy: hypertrophy refers to an increase in the number of cells in an organ or tissue. B.The phenotype of an individual cell may be altered in hypertrophy. Guy Brown is Professor of Cellular Biochemistry at the University of Cambridge, where he teaches and directs research at the Laboratory of Cell Physiology & Pathology, which researches: microglia, phagocytosis & inflammation in brain pathology.
