Summary
Caspases, enzymes crucial for apoptosis, also manage cellular stress without causing cell death. Understanding these non-lethal roles is key for human health and disease, though caspase therapies face limitations due to incomplete knowledge.
Area of Science:
- Cellular biology
- Molecular medicine
- Biochemistry
Background:
- Cellular stress is a major factor in human diseases.
- Dysfunctional cells must be removed via cell death pathways like apoptosis to maintain organ function.
- Caspases are key proteases in apoptosis.
Purpose of the Study:
- To discuss the role of caspases as cellular stress managers.
- To explore the impact of non-lethal caspase functions on human health and disease.
- To highlight limitations in caspase-based therapies.
Main Methods:
- Literature review of caspase functions.
- Analysis of non-apoptotic roles of caspases.
- Discussion of implications for disease and therapy.
Main Results:
- Caspases can regulate cellular processes without inducing cell death.
- Some non-lethal caspase activities may restore cellular balance under stress.
- Caspase functions extend beyond apoptosis.
Conclusions:
- Caspases act as crucial cellular stress managers.
- Further research into non-apoptotic caspase roles is needed for therapeutic development.
- Current understanding of caspases limits the efficacy of caspase-based therapies.

Caspase, a family of cysteine proteases, serve as effectors in apoptosis. The ced3 gene in C.elegans was first identified to be involved in apoptosis. This gene encodes the ced-3 caspase that is similar to the interleukin-1-beta converting enzyme or ICE in mammals. In addition to apoptosis, caspases also function in the inflammatory response. Inflammatory caspases are essential in activating pro-inflammatory cytokines that recruit immune cells and block the replication of pathogens inside...

01:31The Intrinsic Apoptotic Pathway
6.6K
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

01:31Regulation of the Unfolded Protein Response
2.4K
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

01:17The Extrinsic Apoptotic Pathway
6.4K
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

01:30Apoptosis
11.5K
Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size...

01:18Autophagic Cell Death
3.4K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
