Glucocorticoid receptors (GR) regulate gene expression and immune responses. Understanding GR action, including its interaction with NF-kB, is key to immune homeostasis and potential clinical applications.
Area of Science:
- Molecular Biology
- Endocrinology
- Immunology
Context:
- Glucocorticoid hormones regulate cellular processes and physiological responses via intracellular receptors.
- Hormone-receptor complexes activate gene networks, influencing cell function and differentiation.
- Glucocorticoid receptor (GR) analysis provides insight into transcriptional control and cell identity.
Purpose:
- To elucidate the general molecular mechanisms of glucocorticoid action.
- To detail how hormone-receptor complexes control differential gene expression patterns (positive and negative).
- To review the role of GR in cellular functions, including immune responses, and emerging clinical aspects.
Summary:
- Glucocorticoid receptors (GR) mediate hormone action by binding to DNA and regulating gene expression.
- The interplay between GR and NF-kB pathways governs immune and inflammatory responses, crucial for immune homeostasis.
- Beyond receptor number and properties, receptor isoforms and transcription factors modulate glucocorticoid responsiveness.
Impact:
- Understanding GR mechanisms is vital for comprehending transcriptional control and cell function.
- Insights into GR and NF-kB interactions offer potential therapeutic targets for immune-related diseases.
- This review highlights emerging clinical aspects of molecular glucocorticoid action, paving the way for novel treatments.
