Insights

This review examines the NRF2/Keap1 pathway

Area of Science:

  • Gastroenterology and Immunology
  • Molecular Biology
  • Drug Discovery

Background:

  • Oxidative stress (OS) is a key factor in inflammatory bowel disease (IBD) pathogenesis.
  • Previous clinical trials targeting OS in IBD have shown inconsistent outcomes.
  • The NRF2/Keap1 pathway regulates cellular antioxidant defenses and is implicated in IBD.

Purpose of the Study:

  • To review human evidence on modulating the NRF2/Keap1 pathway in IBD.
  • To explore the NRF2/Keap1 pathway as a therapeutic target for IBD.
  • To present compounds that activate this pathway for potential clinical use.

Main Methods:

  • Literature review of studies investigating the NRF2/Keap1 pathway in IBD.
  • Analysis of existing human data on NRF2/Keap1 modulation.
  • Identification and summary of compounds targeting the NRF2/Keap1 axis.

Main Results:

  • Dysregulation of the NRF2/Keap1 pathway is observed in IBD.
  • Activation of NRF2/Keap1 may enhance antioxidant responses, potentially mitigating IBD.
  • Evidence for direct clinical modulation of NRF2/Keap1 in IBD is currently limited.

Conclusions:

  • The NRF2/Keap1 pathway represents a promising therapeutic target for IBD.
  • Further research and clinical trials are needed to validate compounds targeting this pathway.
  • Modulating NRF2/Keap1 offers a potential strategy to improve IBD treatment outcomes.

NF-κB-dependent Signaling Pathway02:26

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.

Inflammatory Bowel Disease IV: Pharmacological Management

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF01:24

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Drugs for Treatment of Ulcerative Colitis in IBD01:29

Drugs for Treatment of Ulcerative Colitis in IBD

Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...
