Insights

Disulfidptosis is a new cell death pathway. It involves NADPH depletion and cystine accumulation, causing disulfide bonds in actin and cell death, distinct from other programmed cell death types.

Area of Science:

  • Cell Biology
  • Biochemistry
  • Pathology

Background:

  • Discovered a novel cell death pathway termed disulfidptosis.
  • Distinguishable from apoptosis, pyroptosis, autophagy, ferroptosis, and oxeiptosis.
  • Characterized by rapid nicotinamide adenine dinucleotide phosphate (NADPH) depletion and solute carrier family 7 member 11 (SLC7A11) upregulation during glucose starvation.

Purpose of the Study:

  • To review the mechanisms, influencing factors, and disease associations of disulfidptosis.
  • To compare disulfidptosis with established programmed cell death pathways.
  • To explore the application prospects and future research directions for disulfidptosis.

Main Methods:

  • Literature review of disulfidptosis.
  • Analysis of molecular mechanisms.
  • Comparison with other cell death modalities.

Main Results:

  • Disulfidptosis is triggered by glucose starvation, leading to NADPH depletion and SLC7A11 overexpression.
  • Abnormal cystine accumulation results in aberrant disulfide bond formation in actin.
  • Actin cytoskeleton collapse is the terminal event in disulfidptosis.

Conclusions:

  • Disulfidptosis represents a distinct programmed cell death pathway.
  • Understanding disulfidptosis mechanisms offers potential therapeutic targets for related diseases.
  • Further research is needed to fully elucidate its role and applications.

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...

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...

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...

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...

Cell Motility through Blebbing01:16

Cell Motility through Blebbing

Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.
