Autophagy degrades damaged organelles, cell membranes and proteins, and insufficient autophagy is thought to be one of the main reasons for the accumulation of damaged cells and aging. [87] Autophagy and autophagy regulators are involved in response to lysosomal damage, often directed by galectins such as galectin-3 and galectin-8 .
Programmed cell death (PCD; sometimes referred to as cellular suicide [1]) is the death of a cell as a result of events inside of a cell, such as apoptosis or autophagy. [2] [3] PCD is carried out in a biological process, which usually confers advantage during an organism's lifecycle.
Autolysis is uncommon in living adult organisms and usually occurs in necrotic tissue as enzymes act on components of the cell that would not normally serve as substrates. These enzymes are released due to the cessation of active processes in the cell that provide substrates in healthy, living tissue; autolysis in itself is not an active process.

Necrosis (from Ancient Greek νέκρωσις (nékrōsis) 'death') is a form of cell injury which results in the premature death of cells in living tissue by autolysis. [1] The term "necrosis" came about in the mid-19th century and is commonly attributed to German pathologist Rudolf Virchow , who is often regarded as one of the founders of ...

Atg1 is a kinase upregulated upon induction of autophagy. Atg13 regulates Atg1 and together they form a complex called Atg13:Atg1, which receives signals from the master of nutrient sensing – Tor. Atg1 is also important in late stages of autophagosome formation. [8]
Visible changes caused by decomposition are limited during the fresh stage, although autolysis may cause blisters to appear at the surface of the skin. [ 13 ] The small amount of oxygen remaining in the body is quickly depleted by cellular metabolism and aerobic microbes naturally present in respiratory and gastrointestinal tracts, creating an ...
