Abstract We investigated the mechanisms of stress-induced alterations in adrenocorticotrophin (ACTH) release. Tandem parachutists received either a placebo or the β-adrenoceptor antagonist propranolol prior to a first time parachute jump. Blood samples were drawn 4 h before, immediately after, and 1 h after the jump. Cortisol and catecholamine concentrations displayed a significant stress-induced increase in both groups. The ACTH plasma concentrations significantly increased in the placebo and… 
No Effect of 5-Day Treatment with Acetylsalicylic Acid (Aspirin) or the Beta-Blocker Propranolol (Inderal) on Free Cortisol Responses to Acute Psychosocial Stress: A Randomized Double-Blind, Placebo-Controlled Study
TLDR
Neither short-term treatment with aspirin nor propranolol altered the acute free cortisol response to psychological stress in healthy adults.
Psychosocial stress and cardiovascular disease: The role of the hypothalamic-pituitary-adrenal axis
TLDR
A body of work indicates that alterations in HPA axis function play a role in CVD and that the serotonergic system likely plays a roles in stress-related dysregulation of the HPA Axis, thereby having therapeutic implications for stress- related illness such as CVD.
Inflammation and cortisol response in coronary artery disease
TLDR
Previous studies of glucocorticoids in coronary atherosclerosis and myocardial infarction consistently point towards a dysregulated cortisol secretion that may involve a failure to contain inflammatory activity.
Characterization of thymocyte phenotypic alterations induced by long-lasting β-adrenoceptor blockade in vivo and its effects on thymocyte proliferation and apoptosis
TLDR
It is suggested that pharmacological manipulations with β-AR signaling, or chemically evoked alterations in catecholamine release, may interfere with the regulation of thymocyte selection, and consequently with the immune response.
Dehydroepiandrosterone decreases mortality rate and improves cellular immune function during polymicrobial sepsis
TLDR
It is demonstrated that DHEA administration leads to an increased survival following a septic challenge and may, therefore, be beneficial in systemic inflammation.
Reactivity and recovery from different types of work measured by catecholamines and cortisol: a systematic literature overview
TLDR
In occupational settings it was found that relatively few studies were conclusive about recovery, which formed a contrast with sports research, and more research is needed on the course of recovery relative to health effects in occupational settings.
Impaired cortisol response to acute stressors in patients with coronary disease. Implications for inflammatory activity
TLDR
It is hypothesized that an altered hypothalamic‐pituitary adrenal adrenal axis activity was linked to a disinhibited inflammatory activity in patients with coronary artery disease (CAD).

Adrenergic mechanisms in the control of corticotrophin secretion.
TLDR
In both man and rat, activation of central alpha-1 adrenoceptors is followed by increased ACTH secretion and this mechanism is important in the control of secretion of this hormone under some physiological circumstances.
THE EFFECT OF PERIPHERAL CATECHOLAMINE CONCENTRATIONS ON THE PITUITARY‐ADRENAL RESPONSE TO CORTICOTROPHIN RELEASING FACTOR IN MAN
TLDR
Results show that modulation of peripheral plasma catecholamine levels within physiological limits does not affect CRF‐stimulated release of ACTH or the adrenal response in normal man.
Adrenergic regulation of α-MSH secretion in man : evidence for a stimulatory role of β-receptors
TLDR
The results indicate that in man the adrenergic system stimulates alpha- MSH-LI release through beta-receptors, and that alpha-MSH- LI secretion is dissociated from that of ACTH and cortisol, which suggests that separate neuroregulatory mechanisms exist for the melanotrope and corticotroPE cells.

Epinephrine or norepinephrine fail to influence pituitary-adrenal secretion in man.
TLDR
In man, physiologic increases in circulating catecholamines have no influence on pituitary-adrenal hormone concentrations as observed during intense psychological stress or exhausting physical exercise.
Cardiovascular and sympathoadrenal responses to mental stress: influence of beta-blockade.
TLDR
The results suggest that mental stress accelerates the heart through neurogenic mechanisms and that peripheral vasodilatation is achieved through the concerted actions of reduced vasoconstrictor activity and elevated circulating Epi.

β-Adrenoceptor activation mediates stress-induced secretion of β-endorphin-related peptides from intermediate but not anterior pituitary
TLDR
In rat the β-adrenoceptor antagonist (−)propranolol reduces or abolishes the rapid increase of immunoreactive β-endorphin levels during some stress stimuli but not during others (ether, formalin, laparotomy).
