Insights

Transforming growth factor-β (TGF-β) is a key driver of fibrosis. Targeting downstream pathways and interactions offers promising antifibrotic therapies with potentially fewer side effects than direct TGF-β inhibition.

Area of Science:

  • Fibrosis research
  • Molecular biology
  • Pharmacology

Background:

  • Transforming growth factor-β (TGF-β) is a central mediator in the development of fibrosis.
  • Direct inhibition of TGF-β signaling can lead to adverse effects.
  • TGF-β exerts profibrotic effects through various intracellular signaling cascades.

Purpose of the Study:

  • To review potential therapeutic targets within the TGF-β pathway for antifibrotic therapies.
  • To explore alternative intervention points beyond direct TGF-β inhibition.
  • To identify targets with high translational potential for treating fibrotic diseases.

Main Methods:

  • Literature review of studies on TGF-β signaling in fibrosis.
  • Analysis of intracellular cascades regulated by TGF-β.
  • Examination of interactions between TGF-β and other profibrotic pathways.
  • Identification of pharmacologic targets with translational promise.

Main Results:

  • Several intracellular signaling cascades downstream of TGF-β present viable therapeutic targets.
  • Interactions between TGF-β and other profibrotic pathways offer additional intervention strategies.
  • Targeting these alternative pathways may mitigate the adverse effects associated with direct TGF-β inhibition.

Conclusions:

  • Alternative targets within and interacting with the TGF-β pathway hold significant potential for developing novel antifibrotic therapies.
  • Pharmacologic intervention in downstream or interacting pathways represents a promising strategy for managing fibrotic diseases.
  • Further research into these targets could lead to more effective and safer antifibrotic treatments.

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...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

Cystic Fibrosis: Pathogenesis01:23

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

What is Cell Signaling?02:03

What is Cell Signaling?

Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate to respond to the environment.

Endocrine Signaling01:45

Endocrine Signaling

Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.

Paracrine Signaling01:21

Paracrine Signaling

Paracrine signaling allows cells to communicate with their immediate neighbors via secretion of signaling molecules. Such a signal can only trigger a response in nearby target cells because the signal molecules degrade quickly or are inactivated if not taken up. Prominent examples of paracrine signaling include nitric oxide signaling in blood vessels, synaptic signaling of neurons, the blood clotting system, tissue repair/wound healing, and local allergic skin reactions. Nitric oxide as a...
