Autolysis (biology)
In biology, autolysis, more commonly known as self-digestion, refers to the destruction of a cell through the action of its own enzymes. It may also refer to the digestion of an enzyme by another molecule of the same enzyme.
The term derives from the Greek words αὐτο- ("self") and λύσις ("splitting").
== Cell destruction ==
Autolytic cell destruction is uncommon in living adult organisms and usually occurs in injured cells or dying tissue. Autolysis is initiated by the cells' lysosomes releasing digestive enzymes into the cytoplasm. These enzymes are however released due to the cessation of active processes in the cell, not as an active process. In other words, though autolysis resembles the active process of digestion of nutrients by live cells, the dead cells are not actively digesting themselves as is often claimed and as the synonym ''self-digestion'' of autolysis seems to imply. Autolysis of individual cell organelles can be lessened if the organelle is stored in ice-cold isotonic buffer after cell fractionation.
