The glucocorticoid receptor (GR or GCR) also known as NR3C1 (nuclear receptor subfamily 3, group C, member 1) is the receptor to which cortisol and other glucocorticoids bind. (wikipedia.org)
After the receptor is bound to glucocorticoid, the receptor-glucocorticoid complex can take either of two paths. (wikipedia.org)
The endogenous glucocorticoid hormone cortisol diffuses through the cell membrane into the cytoplasm and binds to the glucocorticoid receptor (GR) resulting in release of the heat shock proteins. (wikipedia.org)
In central nervous system structures, the glucocorticoid receptor is gaining interest as a novel representative of neuroendocrine integration, functioning as a major component of endocrine influence - specifically the stress response - upon the brain. (wikipedia.org)
Dexamethasone and other corticosteroids are agonists, while mifepristone and ketoconazole are antagonists of the GR. Anabolic steroids also prevent cortisol from binding to the glucocorticoid receptor. (wikipedia.org)
Moreover, these HFD effects were normalized by treatment with glucocorticoid receptor (GR) antagonists. (nature.com)
At the cellular level, the actions of glucocorticoids are mediated by a 94-kd protein, the glucocorticoid receptor (GR). The human (h) GR belongs to the steroid/thyroid/retinoic acid superfamily of nuclear receptors and functions as a ligand-dependent transcription factor that regulates the expression of glucocorticoid-responsive genes positively or negatively.

The glucocorticoid receptor (GR) is essential for the correct functioning of the HPA axis, thus alterations in the expression of the GR through altered methylation of the GR gene ( NR3C1 ) (and more specifically exon 1F) might contribute to the development of NSSI in individuals with a history of ACEs, as has been reported for different other mental disorders.
