Insights

Fusarium mycotoxins like Fumonisin B1 can trigger cell death (apoptosis) in various human and animal cells. Complex mechanisms involving sphingolipids and signaling pathways may underlie this toxicity.

Area of Science:

  • Toxicology
  • Cell Biology
  • Biochemistry

Background:

  • Fusarium mycotoxins are toxic secondary metabolites produced by fungi.
  • Several Fusarium mycotoxins, including Fumonisin B1, T-2 toxin, Fusarenon-X, and Deoxynivalenol, are known to affect cellular health.
  • Apoptosis, or programmed cell death, is a critical cellular process implicated in various physiological and pathological conditions.

Purpose of the Study:

  • To investigate the potential of specific Fusarium mycotoxins to induce apoptosis in different cell types.
  • To explore the complex molecular mechanisms potentially involved in Fusarium mycotoxin-induced apoptosis.

Main Methods:

  • Exposure of various human and animal cell lines (liver, kidney, gastrointestinal epithelial, immunological cells) to Fumonisin B1, T-2 toxin, Fusarenon-X, and Deoxynivalenol.
  • Analysis of cellular responses to identify induction of apoptosis.
  • Investigation of potential molecular pathways, including sphingolipid metabolism, p21 gene expression, protein kinase activity, cAMP signaling, and intracellular calcium levels.

Main Results:

  • Fumonisin B1, T-2 toxin, Fusarenon-X, and Deoxynivalenol were confirmed to induce apoptosis in liver cells, kidney cells, gastrointestinal epithelial cells, and immunological cells.
  • Apoptosis was also observed in several tested human and animal cell lines.
  • Preliminary findings suggest that sphingolipids, p21 gene, protein kinases, the cAMP signaling system, and intracellular calcium levels may play roles in the observed apoptosis.

Conclusions:

  • Fusarium mycotoxins possess the ability to induce apoptosis across a range of critical cell types in humans and animals.
  • The mechanisms underlying Fusarium mycotoxin-induced apoptosis are intricate and likely involve multiple cellular pathways.
  • Further research is warranted to fully elucidate the specific roles of sphingolipids, genetic factors, and signaling cascades in Fusarium mycotoxin toxicity.

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 reduction of the tissue.
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...
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 by phagocytes.
Cellular Injury V: Apoptosis and Autophagy01:22

Cellular Injury V: Apoptosis and Autophagy

Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...
