Summary
Nuclear receptors, like the glucocorticoid receptor (GR), play a crucial role in regulating inflammation. These transcription factors can repress inflammatory genes, offering therapeutic potential for chronic inflammatory diseases.
Area of Science:
- Molecular Biology
- Immunology
- Endocrinology
Background:
- Inflammation is a critical biological response to injury and infection.
- Dysregulated inflammatory pathways contribute to chronic diseases like autoimmune and neurodegenerative disorders.
- Nuclear receptors (NRs) are key transcription factors with known anti-inflammatory properties.
Purpose of the Study:
- To explore the established and emerging roles of Nuclear Receptors (NRs) in inflammation.
- To elucidate the mechanisms by which NRs, particularly the glucocorticoid receptor (GR), regulate inflammatory gene expression.
Main Methods:
- Review of established and emerging literature on Nuclear Receptors and inflammation.
- Focus on the molecular mechanisms of GR in repressing pro-inflammatory gene transcription.
Main Results:
- NRs, including GR, are potent regulators of inflammatory signaling pathways.
- GR directly represses the expression of genes encoding pro-inflammatory mediators like cytokines and chemokines.
- NRs modulate transcription factor activity, cofactors, and chromatin remodeling to control inflammation.
Conclusions:
- Nuclear receptors, especially GR, represent significant targets for managing chronic inflammatory conditions.
- Understanding NR-mediated repression of inflammatory genes is vital for developing novel anti-inflammatory therapies.

01:31Transducer 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:

02:04Co-activators and Co-repressors
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

02:26NF-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.

01:26Signal Transduction: Overview
Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.
Typically, signal transduction involves three...

01:28Inflammatory 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,...
