We investigated the effects of intraperitoneal injection of alpha- and beta-adrenergic antagonists on psychological stress-induced responses in free-moving rats. Psychological stress was induced by immersion in 2-cm-deep water. The intraperitoneal injection of the alpha-adrenergic blocker, phentolamine (10 mg/kg), attenuated the stress-induced rise in body temperature and hypertension but enhanced tachycardia. In contrast, intraperitoneal injection of the beta-adrenergic blocker, propranolol (1 mg/kg), suppressed tachycardia but had no effect on rise in body temperature and hypertension during

The dopamine plasma level was elevated only in the case of adrenergic urticaria. The symptoms could be reproduced by intradermal injection of adrenalin and noradrenalin and treated successfully with propanolol, a blocker of beta-adrenergic receptors.

These increases are significant because 1) all brain regions are often affected, i.e., certain stressful events have global effects on cerebral blood flow and energy metabolism; and 2) various stressful events appear to have a common adrenergic mechanism for increasing cerebral blood flow and energy metabolism.

Abstract Adrenergic stress promotes tumor progression by several mechanisms. Mice housed at standard housing temperature (ST, 22°C) experience chronic adrenergic cold stress sufficient to elevate norepinephrine levels compared to mice housed at thermoneutrality (TT, 30°C) and we found that tumors grow faster at ST. We have also previously reported that the anti-tumor immune response is suppressed at ST. Tumor infiltrating CD8+ T cells from these mice have reduced expression of activation and effector function markers. These deficits are reversed by housing mice at TT which reduced adrenergic s

Rainbow trout, Oncorhynchus mykiss, were injected with an adrenergic agonist, an adrenergic antagonist, or a cholinergic antagonist, via a dorsal aorta cannula. Spleen size and haemoglobin content were measured at rest and, for antagonists, following an air exposure stress. Injection of phentolamine (an α-antagonist) blocked the spleen contraction induced by air exposure, suggesting that control is mediated by α-adrenergic receptors. Air exposure effects were unaffected by β-adrenergic blockade or muscarinic cholinergic blockade.

Previous studies have indicated that the adrenergic receptor signaling pathway plays a fundamental role in chronic stress-induced cancer metastasis. In this study, we investigated whether an ethanol extract of Perilla frutescens leaves (EPF) traditionally used to treat stress-related symptoms by moving Qi could regulate the adrenergic agonist-induced metastatic ability of cancer cells. Our results show that adrenergic agonists including norepinephrine (NE), epinephrine (E), and isoproterenol (ISO) increased migration and invasion of MDA-MB-231 human breast cancer cells and Hep3B human hepatoce

Abstract We have shown previously that host adrenergic stress (model of standard ambient temperature-induced chronic stress) slows tumor progression by enhancing CD8+ T-cell activation and limiting the suppressive function of myeloid-derived suppressor cells in the tumor microenvironment (TME). We also found that reducing/blocking β-adrenergic receptor (β-AR) signaling significantly improves anti-tumor immune responses and efficacy of immune checkpoint immunotherapy. It has been reported that expression of immune checkpoint receptors (e.g. PD-1, TIM3, LAG3) is characteristic of exhausted T-cel

Background Stress has paradoxical effects on pain, causing stress-induced analgesia but also exacerbating pain via poorly understood mechanisms. Adrenergic neurotransmission is integral in pathways that regulate the response to both pain and stress. Hyperalgesia is often associated with enhanced adrenergic sensitivity of primary afferents, but sympathetic nervous system outflow has not been demonstrated to exacerbate pain perception after stress.

Background: Exercise has beneficial effects on cancer and its treatment, but the underlying mechanisms are poorly understood. Some studies have linked the positive impact of exercise to catecholamine signaling. In contrast, cancer stress studies have typically reported that catecholamines worsen cancer hallmarks and outcomes. Here, we aimed to investigate whether adrenergic receptor isoform expression can explain the contradictory effects of catecholamines in cancer.

Abstract Prolonged maternofetal stress stunts placental development and causes fetal programming that reduces fetal growth and birthweight. Low birthweight due to intrauterine growth restriction (IUGR) of the fetus increases perinatal mortality. More commonly, however, it results in lifelong impairment of muscle growth capacity and metabolic function. In humans, low birthweight increases risk for obesity, diabetes, and other metabolic disorders by an estimated 18-fold. Similarly, low birthweight livestock exhibit greater early death loss, poor growth efficiency, and lower-quality carcasses at

On the one hand, sustained β-adrenergic stress is a hallmark of heart failure (HF) and exerts maladaptive cardiac remodelling. On the other hand, acute β-adrenergic stimulation maintains cardiac function under physiological stress. However, it is still incompletely understood to what extent the adaptive component of β-adrenergic signaling contributes to the maintenance of cardiac function during chronic β-adrenergic stress. We developed an experimental catecholamine-based protocol to distinguish adaptive from maladaptive effects. Mice were for 28 days infused with 30 mg/kg body weight/day isop

Abstract In this review we discuss the adrenergic pathways for alpha 1 and alpha 2 receptors and the current as well as potential future medication targeting these receptors. Overall, there is ongoing research into a multitude of directions with a promising outlook for alpha 1 and alpha 2 adrenergic receptors. The alpha 1-adrenergic receptor subfamily is currently modulating only a modest number of nervous system functions due the fact, that only a relatively small number of selective commercial products are available. Chronic stress can affect the long-term depression of alpha 1 receptors. Re

After exposure to cold stress, animals enhance the production of beige adipocytes and expedite thermogenesis, leading to improved metabolic health. Although brown adipose tissue in rodents is primarily induced by β3-adrenergic receptor (ADRB3) stimulation, the activation of major β-adrenergic receptors (ADRBs) in pigs has been a topic of debate. To address this, we developed overexpression vectors for ADRB1, ADRB2, and ADRB3 and silenced the expression of these receptors to observe their effects on the adipogenic differentiation stages of porcine preadipocytes.

To examine the influence of alpha-adrenergic vasoconstriction on the aerobic capacity of dogs, we calculated O2 consumption (VO2) by the Fick method during submaximal and maximal exertion before and during alpha-adrenergic blockade with phentolamine. Regional blood flow was measured with radioactive microspheres. alpha-Adrenergic receptor blockade reduced VO2 by 12.9% during submaximal and 17.9% during maximal exercise. Arterial and venous lactic acid approximately doubled during both levels of stress in the presence of alpha-adrenergic receptor blockade. Calculated VO2 decreased because arter

ABSTRACT Stress has long been correlated with susceptibility to microbial infection. One explanation for this phenomenon is the ability of pathogens to sense and respond to host stress-related catecholamines, such as norepinephrine (NE). In Gram-negative enteric pathogens, it has been proposed that NE may facilitate growth by mediating iron supply, or it may alter gene expression by activating adrenergic sensor kinases. The aim of this work was to investigate the relative importance of these processes in a model in which NE alters the outcome of Salmonella enterica serovar Typhimurium infectio

The fetus mounted a brisk insulin response to hyperglycemia but with only a minimal change in the glucose-to-insulin ratio, indicating a tight coupling between insulin secretion and plasma glucose. In well-oxygenated fetuses, α2-adrenergic blockade by idazoxan effected no change in fetal insulin concentration, indicating the a

Abstract Chronic stress significantly impacts cancer progression by fostering an immunosuppressive microenvironment that promotes tumor growth and diminishes therapeutic efficacy. Dysregulated stress hormones, like norepinephrine, mediate β-adrenergic stimulation, orchestrating a cascade of immunomodulatory events within the tumor microenvironment (TME). In estrogen receptor-positive (ER+) breast cancer, immunosuppression presents a challenge due to resistance to immunotherapy driven by molecular characteristics dampening antitumor immune responses.
