Abstract

Insights

Farnesoid X receptor (FXR) is a key regulator of metabolism and inflammation. This review highlights FXR's anti-inflammatory and anti-fibrotic roles in chronic diseases, identifying it as a potential therapeutic target.

Area of Science:

  • Nuclear hormone receptor superfamily
  • Ligand-dependent transcription factor

Background:

  • FXR regulates bile acid, lipid, and carbohydrate metabolism.
  • FXR also plays a significant role in inflammatory responses.
  • Its anti-inflammatory and anti-fibrotic effects in chronic diseases require further documentation.

Purpose of the Study:

  • Review developments in farnesoid X receptor (FXR) biology.
  • Discuss FXR ligands and functions, focusing on anti-inflammatory and anti-fibrotic roles.
  • Explore FXR's potential in treating chronic inflammatory diseases.

Main Methods:

  • Literature survey conducted using PubMed database.
  • Focused on gathering information regarding FXR and its role in inflammation.

Main Results:

  • FXR is highly expressed in the liver, intestine, kidney, and adrenals.
  • Natural ligands include primary bile acids; synthetic agonists like GW4064 exist.
  • FXR is a key metabolic regulator with potential as a drug target.

Conclusions:

  • FXR demonstrates significant anti-inflammatory and anti-fibrotic properties.
  • Its role in chronic inflammatory diseases is a promising area for therapeutic development.
  • FXR represents a potential drug target for metabolic syndromes involving inflammation.

Inflammatory Response01:28

Inflammatory Response

An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Transducer Mechanism: Nuclear Receptors

Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

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.

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...

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...

Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
