Comprehensive Physiology, 2014 Abstract The hypothalamic‐pituitary‐adrenal (HPA) axis regulates circulating levels of glucocorticoid hormones, and is the major neuroendocrine system in mammals that provides a rapid response and defense against stress.

The hormones of the hypothalamus-pituitary-adrenal (HPA) axis influence memory in situations of acute and chronic stress. The present review tries to summarize the current state of knowledge by describing the enhancing as well as the impairing effects of stress or glucocorticoid (GC) treatment documented in animals and humans.

The HPA axis and cocaine reinforcement
Psychoneuroendocrinology, 2002Scientists have been aware of the existence of a complex relationship between stress and the subsequent activation of the hypothalamic-pituitary-adrenal (HPA) axis and the endocrine and neurobehavioral effects of cocaine for many years now. Our research program has focused on the involvement of HPA axis activation in cocaine reinforcement using the ...

The HPA axis and perinatal depression: a hypothesis
Archives of Women's Mental Health, 2006Episodes of depression and anxiety are as common during pregnancy as postpartum. Some start in pregnancy and resolve postpartum, others are triggered by parturition and some are maintained throughout. In order to determine any biological basis it is important to delineate these different subtypes.

Cytokine Activation of the HPA Axis
Annals of the New York Academy of Sciences, 2000Abstract:The observation that administration of interleukin‐1 (IL‐1) to animals activates the hypothalamo‐pituitary‐adrenocortical (HPA) axis stimulated great interest in the significance and mechanism of this response, and in whether other cytokines have similar activities.

Effects of kisspeptin on parameters of the HPA axis
Endocrine, 2011The hypothalamo-pituitary-adrenal (HPA) and hypothalamo-pituitary-gonadal (HPG) axes have an intricate cross talk that results in the inhibition of reproductive functions during periods of chronic physiological or psychological stress. Recent studies have shown that kisspeptin neurons have projections to many non-reproductive areas of the brain ...

ABSTRACT Stress is an integral part of life. Activation of the hypothalamus‐pituitary‐adrenal (HPA) axis in the adult can be viewed as mostly adaptive to restore homeostasis in the short term. When stress occurs during development, and specifically during periods of vulnerability in maturing systems, it can ...

Glucocorticoids and the HPA axis
2001The glucocorticoids, cortisol and/or corticosterone depending on the species, are steroid hormones produced by cells in the zona fasciculata of the adrenal cortex under the influence of the hypothalamo-pituitary complex (Fig. 1). In normal circumstances their serum concentrations are maintained within narrow limits with pronounced excursions occurring ...

The HPA Axis in HIV-1 Infection
JAIDS Journal of Acquired Immune Deficiency Syndromes, 2002Several lines of evidence suggest that neuroendocrine abnormalities in general and HPA axis activity in particular occur in both HIV-1 infection and individuals engaging in chronic drug use. For instance, our studies showing attenuated norepinephrine as well as ACTH and cortisol responses to a cold pressor challenge in asymptomatic HIV-1 persons ...
