Insights

Fibrotic diseases lack treatments. Targeting the transforming growth factor beta (TGFβ) pathway is difficult, but the jagged/Notch pathway may offer a new therapeutic approach for fibrosis.

Area of Science:

  • Fibrosis research
  • Cell signaling pathways
  • Molecular medicine

Background:

  • Fibrotic diseases remain untreatable, posing significant health challenges.
  • Transforming growth factor beta (TGFβ) is a key driver of fibrogenesis.
  • Directly targeting TGFβ is complicated by its diverse biological functions.

Purpose of the Study:

  • To comment on recent findings suggesting a novel therapeutic strategy for fibrosis.
  • To explore the role of the jagged/Notch pathway in mediating TGFβ's fibrogenic effects.
  • To evaluate the potential of targeting the jagged/Notch pathway for treating fibrotic conditions.

Main Methods:

  • Review and commentary on published research (Kavian et al. 2010; Nyhan et al. 2010).
  • Analysis of the proposed mechanism involving the jagged/Notch pathway.
  • Discussion of implications for fibrotic disease treatment.

Main Results:

  • Recent studies indicate the jagged/Notch pathway selectively mediates TGFβ's fibrogenic properties.
  • This pathway presents a potential alternative to direct TGFβ targeting.
  • The findings offer new insights into the molecular mechanisms of fibrosis.

Conclusions:

  • The jagged/Notch pathway represents a promising novel therapeutic target for fibrotic diseases.
  • Targeting this pathway could overcome limitations associated with broad TGFβ inhibition.
  • This approach holds potential for treating conditions like scleroderma and kidney fibrosis.

Notch Signaling Pathway03:14

Notch Signaling Pathway

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 until 1985...
Introduction to Fibroblasts01:09

Introduction to Fibroblasts

Rudolph Virchow discovered spindle-shaped cells called fibroblasts in 1858. Inactive fibroblasts, called fibrocytes, become activated by various stimuli, such as growth factors and inflammatory cytokines. Activated fibroblasts play a crucial role in wound healing, inflammation, formation of new blood vessels, and cancer progression. Uncontrolled activation of fibroblasts results in fibrosis, the excess deposition of fibrous tissue, which can lead to scarring and affect normal organs. This...
TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...
Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...
Tissue Renewal without Stem Cells01:23

Tissue Renewal without Stem Cells

After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.
However, failure of such a system...
