Summary
Corticotropin-releasing factor (CRF) regulates stress responses via pituitary hormones. CRF receptors are key to these effects and implicated in various disorders, highlighting their therapeutic potential.
Area of Science:
- Neuroendocrinology
- Stress Physiology
- Molecular Pharmacology
Background:
- Corticotropin-releasing factor (CRF) is central to the body's stress response, controlling pituitary hormone release.
- CRF influences endocrine, autonomic, behavioral, and immune systems.
- CRF's role extends to psychiatric and neurodegenerative disorders.
Purpose of the Study:
- To provide a comprehensive overview of Corticotropin-releasing factor (CRF) receptors.
- To discuss the tissue specificity, regulation, and characteristics of CRF receptors.
- To explore the implications of CRF receptors in neuroimmune, neuroendocrine, and behavioral functions, and their role in disease.
Main Methods:
- Literature review synthesizing four decades of research on CRF and its receptors.
- Analysis of molecular-biological, biochemical, and pharmacological data.
- Examination of clinical data implicating CRF in various disorders.
Main Results:
- CRF mediates diverse physiological responses through two distinct CRF receptors.
- CRF receptors are expressed in specific brain areas and various non-neuronal tissues.
- Recent research includes cloning receptor subtypes and discovering new CRF-related ligands.
Conclusions:
- CRF receptors are critical regulators of stress adaptation and physiological homeostasis.
- Dysregulation of the CRF system is linked to numerous endocrine and psychiatric conditions.
- Understanding CRF receptors offers potential therapeutic targets for stress-related disorders.
