Summary
Necroptosis, a regulated cell death pathway involving RIPK-1/3 and MLKL, is implicated in various diseases. Targeting necroptosis offers potential therapeutic strategies for conditions like cancer and inflammatory diseases.
Area of Science:
- Molecular Biology
- Cell Biology
- Pathology
Background:
- Programmed cell death mechanisms are crucial in human health and disease.
- Necroptosis, a regulated form of necrosis, shares features with apoptosis but has distinct molecular players.
- Dysregulation of necroptosis is linked to numerous pathological conditions, including cancer, cardiovascular, inflammatory, and neurodegenerative diseases.
Purpose of the Study:
- To elucidate the molecular mechanisms of necroptosis.
- To explore the role of necroptosis-associated proteins (RIPK-1/3, MLKL) in disease pathogenesis.
- To review therapeutic strategies targeting necroptosis for disease treatment.
Main Methods:
- Review of existing genetic and pharmacological studies on necroptosis.
- Analysis of the function of key necroptosis-associated proteins.
- Discussion of natural compounds and targeted therapies affecting necroptosis.
Main Results:
- Necroptosis is executed via receptor-interacting protein kinase (RIPK)-1/3 and mixed-lineage kinase domain-like (MLKL) activation, forming a necrosome complex.
- RIPKs and MLKL are critical regulators in the progression of multiple pathological diseases.
- Targeting necroptosis can induce cancer cell death, potentially overcoming apoptosis resistance.
Conclusions:
- Understanding necroptosis mechanisms and associated proteins is vital for disease intervention.
- Therapeutic strategies modulating necroptosis show promise for treating various pathologies, particularly cancer.
- Further research into necroptosis modulators may yield novel treatments for drug-resistant diseases.

01:16Necrosis
4.7K
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”.

01:30Overview of Cell Death
7.5K
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...

01:30Apoptosis
11.8K
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
6.5K
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...

01:17Phagocytosis of Apoptotic Cells
3.9K
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.

01:18Autophagic Cell Death
3.5K
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.
