Summary
Caspases are key proteins in cell death and inflammation. New research reveals their complex roles and interactions, crucial for developing therapies for diseases like cancer and inflammatory disorders.
Area of Science:
- Molecular Biology
- Cell Biology
- Immunology
Background:
- Caspases are cysteine proteases vital for programmed cell death and inflammation.
- Activation occurs through signaling complexes inducing procaspase autoactivation.
- Specific caspases dictate the type of cell death executed.
Purpose of the Study:
- To review mechanisms of caspase activation and programmed cell death.
- To highlight recent advances in caspase cross-talk.
- To emphasize caspase-driven gasdermin D-induced pyroptosis.
Main Methods:
- Literature review of pioneering research.
- Analysis of caspase activation pathways.
- Focus on molecular mechanisms of cell death regulation.
Main Results:
- Caspases have distinct roles in regulating programmed cell death, inflammation, and innate immunity.
- Caspase cross-talk significantly influences cellular responses.
- Gasdermin D-mediated pyroptosis is a key caspase-executed cell death pathway.
Conclusions:
- Understanding caspase mechanisms is essential for therapeutic target development.
- Precise targeting can address autoinflammatory disorders, infectious diseases, and cancer.
- Further research into caspase cross-talk and pyroptosis holds therapeutic promise.

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...

01:30Overview of Cell Death
9.1K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

01:31The Intrinsic Apoptotic Pathway
8.1K
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...

01:17The Extrinsic Apoptotic Pathway
7.9K
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
13.7K
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...

01:17Phagocytosis of Apoptotic Cells
4.8K
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or immature dendritic cells. Non-professional phagocytes such as epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes.
