Summary
Necroptosis, a regulated cell death, causes early plasma membrane rupture and releases danger-associated molecular patterns (DAMPs), driving inflammation. Understanding necroptosis mechanisms may offer new therapeutic strategies for related diseases.
Area of Science:
- Cellular biology
- Immunology
- Pathology
Background:
- Necroptosis is a regulated form of cell death.
- It is implicated in various pathological conditions.
- Necroptosis involves early plasma membrane rupture, leading to inflammation via danger-associated molecular patterns (DAMPs) release.
Purpose of the Study:
- To elucidate the mechanisms of plasma membrane rupture (PMR) in necroptosis.
- To understand the release of danger-associated molecular patterns (DAMPs).
- To explore the therapeutic potential of targeting necroptosis signaling pathways.
Main Methods:
- Review of recent studies on necroptosis mechanisms.
- Analysis of stimuli inducing necroptosis (e.g., TNF, viral infection).
- Investigation of necrosome formation and its role in PMR.
Main Results:
- Necroptosis triggers early plasma membrane rupture, distinct from apoptosis.
- The release of intracellular contents (DAMPs) from ruptured cells induces strong inflammatory responses.
- Mutations in necroptosis-related genes are linked to hereditary autoinflammatory syndromes.
Conclusions:
- Necroptosis is a key driver of inflammation through DAMPs release.
- Targeting necroptosis pathways presents a potential therapeutic avenue for diseases associated with this cell death process.

4.5K
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”.

01:30Overview of Cell Death
7.3K
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...

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.

01:17Phagocytosis of Apoptotic Cells
3.8K
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.

12.5K
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...
