Glucocorticoid Receptors are intracellular receptor proteins that serve as the primary mediators for the profound systemic effects of glucocorticoid hormones, such as cortisol. These receptors are widely distributed across nearly all cell types in the body, functioning as ligand-activated transcription factors that directly regulate the expression of a vast network of target genes. Their activation is a central component of the body’s stress response and is the target of all therapeutic corticosteroid medications.
Origin
The term combines “glucocorticoid,” referring to the class of steroid hormones that profoundly influence glucose metabolism, and “receptor,” denoting the specific binding molecule for these hormones. The rigorous identification and molecular characterization of these specific nuclear receptors were seminal achievements in endocrinology and molecular pharmacology in the mid-20th century. This discovery provided the definitive molecular basis for understanding cortisol’s diverse and widespread systemic actions.
Mechanism
The mechanism of action begins when a glucocorticoid hormone binds to the receptor, inducing a conformational change that causes the complex to dissociate from chaperone proteins. The activated hormone-receptor complex then translocates from the cytoplasm into the cell nucleus. Inside the nucleus, the complex binds to specific DNA sequences known as glucocorticoid response elements, leading to either the transcriptional activation or repression of target genes, thereby regulating cellular processes related to inflammation, energy homeostasis, and immune function.
