Summary
Necroptosis, a programmed necrosis, shares molecular signals with apoptosis. This review details necroptosis signaling, focusing on FLIP and IAP proteins, and its role in immune homeostasis.
Area of Science:
- Cellular Biology
- Immunology
Background:
- Necroptosis is a regulated form of necrosis.
- It shares molecular components with apoptosis.
- The balance between apoptosis and necroptosis is critical for cellular health.
Purpose of the Study:
- To summarize the molecular signaling pathways of necroptosis.
- To highlight the role of FLIP and IAP proteins in regulating the apoptosis/necroptosis balance.
- To emphasize the involvement of necroptosis in physiological and pathological conditions, especially immune homeostasis.
Main Methods:
- Literature review and synthesis of existing research on necroptosis signaling.
- Focus on the regulatory mechanisms involving Fas-associated death domain (FADD), receptor-interacting protein kinase (RIPK) and mixed lineage kinase domain-like protein (MLKL).
- Analysis of the interplay between cellular inhibitor of apoptosis proteins (cIAPs) and cellular FLICE-associated protein (cFLIP) in modulating cell death pathways.
Main Results:
- Detailed overview of the necroptosis signaling cascade, including key kinases and executioners.
- Elucidation of how FLIP and IAP proteins fine-tune the decision between apoptosis and necroptosis.
- Demonstration of necroptosis's crucial role in maintaining immune homeostasis and its implication in diseases.
Conclusions:
- Necroptosis is a vital programmed cell death pathway with significant implications for immunity.
- Fine-tuning of FLIP and IAP proteins is essential for balancing apoptosis and necroptosis.
- Understanding necroptosis signaling is key for developing therapeutic strategies for immune-related disorders.

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
7.7K
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
12.0K
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...

03:14Notch Signaling Pathway
4.6K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

01:17The Extrinsic Apoptotic Pathway
6.2K
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...
