Summary
Programmed necrosis, including necroptosis, is a regulated cell death process crucial for immunity and development. This review details its molecular mechanisms, focusing on RIP kinases and TNF signaling.
Area of Science:
- Molecular Biology
- Cell Death Pathways
- Immunology
Background:
- Programmed necrosis is essential for organism development and immune system regulation.
- It plays a role in pathologies and challenges the view of necrosis as a passive process.
- Current understanding of programmed necrosis molecular regulation is limited due to pathway complexity and terminology issues.
Purpose of the Study:
- To review the current state of knowledge on the molecular mechanisms of programmed necrosis.
- To specifically discuss necroptosis, a common form of programmed necrosis.
- To elucidate the roles of RIP1 and RIP3 kinases and TNFα signaling in cell fate decisions.
Main Methods:
- Literature review of programmed necrosis and necroptosis.
- Analysis of molecular signaling pathways involved in programmed necrosis.
- Examination of the roles of RIP kinases and tumor necrosis factor receptor 1 (TNFR1) signaling.
Main Results:
- Programmed necrosis is an active, gene-dependent process with significant physiological roles.
- RIP1 and RIP3 kinases are key regulators of programmed necrosis, particularly necroptosis.
- Tumor necrosis factor α (TNFα) ligation to TNFR1 can trigger cell survival, apoptosis, or necroptosis.
Conclusions:
- Necroptosis is a critical regulated cell death pathway with implications in health and disease.
- Understanding RIP kinases and TNFα signaling is vital for deciphering programmed necrosis.
- Further research is needed to clarify the complex molecular landscape of programmed necrosis.

7.2K
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
11.1K
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...

01:30Apoptosis
16.9K
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...

01:31The Intrinsic Apoptotic Pathway
9.2K
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...

01:18Autophagic Cell Death
5.0K
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.

01:17The Extrinsic Apoptotic Pathway
9.3K
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...
