Central mineralocorticoid receptors mediate impairing effects of corticosterone on memory retrieval in rats

Introduction: Previous studies have indicated that stress levels of glucocorticoid hormones induce impairment of long term memory retrieval, but the underlying mechanisms (genomic or non-genomic) are not clear. To clarify this issue, we investigated the involvement of brain corticosteroid receptors and protein synthesis in the glucocorticoid-induced impairment of memory retrieval. Methods: 140 ...

Divergent effects of amygdala glucocorticoid and mineralocorticoid receptors in the regulation of visceral and somatic pain.

Elevated amygdala activity and increased responsiveness of the hypothalamic-pituitary-adrenal axis have been observed in irritable bowel syndrome (IBS) patients. Recently, we demonstrated that corticosterone (Cort) placed on the amygdala induced anxiety-like behavior coupled with decreased thresholds for visceral and somatic pain in rats. Moreover, these studies suggested that the effects of Co...

Predator stress-induced persistent emotional arousal is associated with alterations of plasma corticosterone and hippocampal steroid receptors in rat.

To investigate the long-term effects of psychological stress on emotionality, the emotional arousal of rats in 4 months after predator stress was assessed in both an open field environment and elevated plus maze. We also assessed the levels of plasma corticosterone (CORT) by radioimmunoassay, the distributions of brain glucocorticoid receptor (GR) and mineralocorticoid receptor (MR) by immunohi...

Repeated blockade of mineralocorticoid receptors, but not of glucocorticoid receptors impairs food rewarded spatial learning.

Corticosteroids from the adrenal cortex influence a variety of behaviours including cognition, learning and memory. These hormones act via two intracellular receptors, the mineralo-corticoid receptor (MR) and the glucocorticoid receptor (GR). These two receptor types display a high concentration and distinct distribution in the hippocampus, a brain region which is directly involved in the regul...

Prenatal stress programs neuroendocrine stress responses and affective behaviors in second generation rats in a sex-dependent manner

An adverse environment in early life is often associated with dysregulation of the hypothalamo-pituitary-adrenal (HPA) axis and higher rates of mood disorders in adulthood. In rats, exposure to social stress during pregnancy results in hyperactive HPA axis responses to stress in the adult offspring and heightened anxiety behavior in the males, but not the females. Here we tested whether, withou...
