Summary
Cellular and environmental microparticles trigger inflammation and disease by activating inflammasome signaling pathways. Targeting these pathways offers potential treatments for various inflammatory disorders.
Area of Science:
- Immunology
- Cell Biology
- Pathology
Background:
- Microparticle accumulation is implicated in numerous inflammatory diseases affecting joints, lungs, kidneys, cardiovascular system, and brain.
- A conserved inflammasome signaling pathway activated by microparticles has recently been identified.
Purpose of the Study:
- To review disease-promoting microparticles and their mechanisms of inflammasome activation.
- To highlight the unique nature of microparticle-induced inflammasome responses.
- To discuss therapeutic strategies targeting inflammasomes for microparticle-driven diseases.
Main Methods:
- Literature review of microparticle-induced inflammasome activation.
- Analysis of mechanisms triggering inflammasome complexes and interleukin-1β (IL-1β) generation.
- Examination of inflammasome and cell death responses.
Main Results:
- Microparticles activate inflammasome complexes, leading to IL-1β production and cell death.
- Microparticle-induced inflammasome activation differs from canonical activators.
- These pathways are crucial in various inflammatory conditions.
Conclusions:
- Microparticles are significant initiators of inflammatory diseases via inflammasome activation.
- Understanding these mechanisms is key to developing novel therapies.
- Targeting inflammasomes presents a promising therapeutic avenue for microparticle-related diseases.

01:17The Extrinsic Apoptotic Pathway
7.7K
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...

01:30Overview of Cell Death
8.9K
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...

01:17Phagocytosis of Apoptotic Cells
4.6K
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.

01:31The Intrinsic Apoptotic Pathway
7.9K
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
13.5K
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...
