Insights

This review explores cell death mechanisms, focusing on necroptosis (programmed necrosis). Understanding necroptosis initiation and signaling is crucial for developing novel cancer therapies.

Area of Science:

  • Cell Biology
  • Molecular Biology
  • Immunology

Background:

  • Apoptosis and necrosis are well-defined cell death types.
  • Emerging necrotic pathways include pyroptosis and ferroptosis.
  • Necroptosis represents a distinct programmed necrosis pathway.

Purpose of the Study:

  • To review the discovery and mechanisms of necroptosis.
  • To explore the signaling cascades of apoptosis and necroptosis.
  • To highlight the role of necroptosis in cancer biology and therapy.

Main Methods:

  • Literature review of cell death pathways.
  • Analysis of molecular players in apoptotic and necroptotic signaling.
  • Discussion of necroptosis initiation via TNFα/TNFR1 and RIPK1/RIPK3/MLKL activation.

Main Results:

  • Necroptosis is a caspase-independent programmed necrosis.
  • TNFα/TNFR1 signaling initiates necroptosis through RIPK1/RIPK3/MLKL complex formation.
  • DAMP release propagates necroptosis, influencing the tumor microenvironment.

Conclusions:

  • Necroptosis is a critical cell death pathway with significant implications for cancer.
  • Targeting necroptosis offers a promising strategy for cancer therapy.
  • The discovery of necroptosis could revolutionize cancer treatment approaches.

Necrosis01:16

Necrosis

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...

Overview of Cell Death01:30

Overview of Cell Death

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...

Autophagic Cell Death01:18

Autophagic Cell Death

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.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and...

The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

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...

Apoptosis01:30

Apoptosis

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...

Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

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. 
Normal cells contain receptors that prevent them from being recognized...
