Summary
Pyroptosis is programmed cell death initiated by gasdermin proteins forming pores. These pores cause cell swelling and rupture, releasing danger signals (DAMPs) that trigger inflammation.
Area of Science:
- Cellular Biology
- Immunology
- Molecular Mechanisms of Cell Death
Background:
- Pyroptosis is a programmed necrosis pathway activated by cellular danger signals.
- It involves cell swelling, lysis, and the release of inflammatory molecules.
- Gasdermin proteins are key executors of pyroptosis.
Purpose of the Study:
- To review the historical context of pyroptosis research.
- To detail recent advancements in understanding gasdermin activation and function.
- To explore the cellular outcomes and physiological relevance of pyroptosis.
Main Methods:
- Literature review of pyroptosis mechanisms.
- Analysis of gasdermin protein family structure and function.
- Examination of cellular consequences of gasdermin pore formation.
Main Results:
- Gasdermins form pores in cellular membranes, leading to pyroptosis.
- Ninjurin-1 (NINJ1) activation contributes to plasma membrane rupture.
- Released DAMPs mediate inflammatory responses.
Conclusions:
- Gasdermin-mediated pore formation is central to pyroptosis.
- Pyroptosis plays roles in host defense and various diseases.
- Further research into gasdermins and pyroptosis is crucial for understanding inflammation and disease.

01:30Overview of Cell Death
5.6K
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
5.7K
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...

01:30Apoptosis
10.1K
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...

01:17The Extrinsic Apoptotic Pathway
5.5K
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...

11.5K
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...

01:16Necrosis
3.7K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
