Summary
The NLRP3 inflammasome (NLRP3) activates pyroptosis and other cell death pathways. Aberrant NLRP3 activation links to inflammatory diseases, suggesting cell death effectors as therapeutic targets.
Area of Science:
- Immunology
- Cell Biology
- Pathology
Background:
- The NLRP3 inflammasome, a cytosolic complex, initiates immune responses.
- It activates caspase-1, inducing pyroptosis and releasing IL-1β/IL-18 for defense.
- Dysregulated NLRP3 inflammasome activation is implicated in inflammatory diseases like diabetes, cancer, and Alzheimer's.
Purpose of the Study:
- To review the intricate relationship between NLRP3 inflammasome activation and various cell death modalities.
- To explore how cell death effectors influence NLRP3 inflammasome activation.
- To discuss therapeutic strategies targeting cell death in NLRP3-associated diseases.
Main Methods:
- Literature review of recent studies on NLRP3 inflammasome and cell death.
- Analysis of the interplay between inflammasome components and cell death pathways.
- Synthesis of findings on therapeutic targets.
Main Results:
- NLRP3 inflammasome activation is linked to pyroptosis, apoptosis, necroptosis, and ferroptosis.
- Cell death effectors reciprocally regulate NLRP3 inflammasome activation.
- A complex crosstalk exists between NLRP3 inflammasome and diverse cell death mechanisms.
Conclusions:
- The NLRP3 inflammasome and cell death pathways are inextricably linked.
- Targeting cell death effectors presents a promising therapeutic avenue for NLRP3-driven inflammatory conditions.

01:17The Extrinsic Apoptotic Pathway
6.9K
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...

01:31The Intrinsic Apoptotic Pathway
7.1K
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...

01:31Regulation of the Unfolded Protein Response
2.7K
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...

01:16Necrosis
5.1K
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”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

01:30Overview of Cell Death
8.1K
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...

01:24Caspases
12.9K
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...
