In which of the following pathological processes caspases are involved in?
Apoptosis can be initiated by external signals that have features in common with those used by ligands such as TNF- or by an internal pathway activated by DNA damage, improperly folded proteins, or withdrawal of cell survival factors. Regardless of the mode of initiation, the apoptotic program is carried out by a large family of cysteineproteases termed caspases. The caspases are highly specific cytoplasmic proteases that are inactive in normal cells but become activated by apoptotic signals. Ref: Blumenthal D.K., Garrison J.C. (2011). Chapter 3.
