The glucocorticoid hypothesis of depression: History and prospects

The purpose of this review was to analyze the available published data on the effects of stress and glucocorticoids on the expression of GRs in the hippocampus, which is traditionally considered as the most sensitive to stress brain structure, and the implication of the interplay ofGRs and BDNF in the pathogenesis of stress-related disorders.

A double-hit model of stress dysregulation in rats: implications for limbic corticosteroid receptors and anxious behavior under amitriptyline treatment

The differential effects among groups could mean that MS would promote an alternative phenotype that is expressed when facing CVS (a double hit) later in life.

Rapid non-genomic effects of corticosteroids and their role in the central stress response.

The recent literature on non-genomic actions of corticosteroids on neuronal activity and functioning in selected limbic brain targets is reviewed, and an essential role for the 'classical' mineralocorticoid and glucoc Corticosteroid receptors in a novel membrane-associated mechanism is found.

Stress Research : Past , Present , and Future

The evolution of the stress concept and the discovery of mediators that coordinate highlighting stress adaptation are discussed and five highlights that illustrate the serendipitous nature of stress research are presented, which culminates in reflections on the role of stress in mental health.

The infralimbic mineralocorticoid blockage prevents the stress-induced impairment of aversive memory extinction in rats

It is observed that acutely restraint-stressed male Wistar rats showed high corticosterone (CORT) levels, and previous intra-IL-spironolactone administration (a selective MR antagonist) decreased it 60 min after the stress started, suggesting that the IL-MR activity controls CORT concentration, and it is crucial to the establishment of late extinction impairment.

Stress effects on memory: An update and integration

The Developmental Psychobiology of Stress and Emotion in Childhood

Under what conditions does stress exposure in childhood induce vulnerability, and when does it promote resilience? In this chapter we review what is known about the developmental psychobiology of

As an adjunct to pharmaceutical therapy, social and behavioral interventions such as regular physical activity and social support reduce the chronic stress burden and benefit brain and body health and resilience.

Stress and the brain: from adaptation to disease

New candidate susceptibility genes that serve as markers for the prediction of vulnerable phenotypes are now being identified in genetically predisposed individuals.

Protective and Damaging Effects of Mediators of Stress: Elaborating and Testing the Concepts of Allostasis and Allostatic Load

Allostatic load reflects not only the impact of life experiences but also of genetic load; individual habits reflecting items such as diet, exercise, and substance abuse; and developmental experiences that set life‐long patterns of behavior and physiological reactivity.

Brain corticosteroid receptor balance in health and disease.

The balance in actions mediated by the two corticosteroid receptor types in these neurons appears critical for neuronal excitability, stress responsiveness, and behavioral adaptation and Dysregulation of this MR/GR balance brings neurons in a vulnerable state with consequences for regulation of the stress response and enhanced vulnerability to disease in genetically predisposed individuals.

Physiological functions of glucocorticoids in stress and their relation to pharmacological actions.

It is proposed that stress-induced increases in glucocorticoid levels protect not against the source of stress itself but rather against the body's normal reactions to stress, preventing those reactions from overshooting and themselves threatening homeostasis.
