Insights

Myofibroblasts (MFs) are key drivers of chronic fibrotic diseases. Targeting conserved MF signaling pathways offers a promising strategy for developing new antifibrotic therapies.

Area of Science:

  • Cell Biology
  • Pathology
  • Immunology

Background:

  • Myofibroblasts (MFs) are crucial in chronic inflammatory and fibroproliferative diseases across various organs.
  • Fibrosis results from persistent injury, inflammation, and profibrogenic interactions involving MFs, precursor cells, and immune cells.
  • MFs exhibit conserved phenotypic traits, including proliferation, extracellular matrix production, migration, and modulation of inflammation and angiogenesis.

Purpose of the Study:

  • To elucidate the critical role of myofibroblasts in fibrotic disease progression.
  • To identify conserved signaling pathways involving MFs and their interactions with other cells in fibrotic tissues.
  • To explore the potential of targeting these pathways for antifibrotic therapeutic strategies.

Main Methods:

  • Review of existing literature on liver, lung, and kidney fibrosis.
  • Analysis of molecular mediators and signaling pathways involved in MF differentiation and function.
  • Identification of conserved regulatory pathways across different fibrotic organs.

Main Results:

  • MFs are central to the initiation and perpetuation of fibrosis through complex cellular interactions.
  • Specific signaling pathways regulating MF differentiation and activity are conserved across different fibrotic organs.
  • These conserved pathways represent potential therapeutic targets for antifibrotic interventions.

Conclusions:

  • Myofibroblast-centric signaling pathways are critical in driving fibrosis.
  • Understanding these conserved pathways is essential for developing effective antifibrotic treatments.
  • Targeting MFs and their associated signaling offers a promising avenue for treating chronic fibrotic diseases.

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...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

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...

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...
