Macrophages play an integral role in eliminating infection during the inflammatory response. Catecholamines are known to alter macrophage function by binding to adrenergic receptors on the macrophage membrane. Stimulation through β-adrenergic receptors (β-AR) is known to decrease macrophage function while stimulation through the α-adrenergic receptor (α-AR) is thought to have a stimulatory effect on immune function. The RAW264.7 murine macrophage cell line is used as a model of macrophage function, but little is known about the expression of adrenergic receptors on these cells. In these studies, macrophages were treated with the catecholamine norepinephrine, the non-selective α-adrenergic receptor agonist clonidine, or the selective α2-adrenergic receptor antagonist RS79948 (RS), prior to lipopolysaccharide (LPS) activation, and then analyzed for the production of the proinflammatory cytokines TNF-α and IL-6. Low concentrations of clonidine increased cytokine production while RS reversed these
TY - JOUR. T1 - α-1 Adrenergic receptors stimulation induces the proliferation of neural progenitor cells in vitro. AU - Hiramoto, Takeshi. AU - Ihara, Yoshiaki. AU - Watanabe, Yasuhiro. PY - 2006/11/6. Y1 - 2006/11/6. N2 - The proliferation of neural progenitor cells (NPCs) is regulated by classical neurotransmitters such as dopamine, serotonin and acetylcholine, via its own receptors. Previous studies have reported that the depletion of l-norepinephrine decreases the proliferation of NPCs in the adult rat hippocampus and it has been suggested that l-norepinephrine regulates the proliferation of NPCs. However, it remains unknown whether or not adrenergic receptors are involved in the increased proliferation of NPCs. In the present study, an MTT cell proliferation assay was carried out in order to investigate the roles played by adrenergic receptors in the proliferation of NPCs. We demonstrated that l-epinephrine enhanced the proliferation of embryonic NPCs in vitro. In addition, the α-1 ...

The mechanisms of desensitization and resensitization of the dopamine D1 receptor are not well understood. Although the high homology of the D1 receptor with the β2-adrenergic receptor might indicate that similar mechanisms regulate the responsiveness of the receptors, even subtypes of β-adrenergic receptors differ substantially in this respect (Shiina et al., 2000). For β-adrenergic receptors, a distinction has been made between desensitization that is homologous (resulting from stimulation of the same receptor) or heterologous (resulting from stimulation of a different receptor subtype, or nonreceptor-mediated activation of a second messenger) (Harden, 1983). A mechanism for heterologous desensitization is phosphorylation of the receptor by PKA (Clark et al., 1989; Hausdorff et al., 1989), whereas homologous desensitization of the β2-adrenergic receptor involves phosphorylation of the agonist-occupied receptor by both GRK (Benovic et al., 1986) and PKA (Post et al., 1996; Moffett et al., ...

Genomics has significantly improved our understanding of chronic obstructive pulmonary disease (COPD) over the past decade. Genome-wide association studies have identified a number of genetic variants associated with lung function and susceptibility to COPD,1 2 and have helped explain why only some smokers develop COPD and why never-smokers can also be affected by the disease. Once COPD is diagnosed, reducing the burden of respiratory exacerbations is a clinical priority because these events are associated with accelerated lung function decline3 and increased mortality.4 However, not all patients with COPD experience exacerbations.5 6 Therefore, identifying individuals at increased risk of exacerbations may help target management and improve outcomes. Beyond the susceptibility to COPD, genomics may also help inform the morbidity of COPD. A previously reported twin study suggests that more than 60% of the risk of severe COPD exacerbations can be attributed to genetic factors.7 Among those, ...
alpha(1B)-Adrenergic receptors mediate many of the actions of the natural catecholamines, adrenaline and noradrenaline. They belong to the seven transmembrane domains G protein-coupled receptor superfamily and exert their actions mainly through activation of Gq proteins and phosphoinositide turnover/calcium signaling. Many hormones and neurotransmitters are capable of inducing alpha(1B)-adrenergic receptor phosphorylation and desensitization; among them: adrenaline and noradrenaline, phorbol esters, endothelin-I, bradykinin, lysophosphatidic acid, insulin, EGF, PDGF, IGF-I, TGF-beta, and estrogens. Key protein kinases for these effects are G protein coupled receptor kinases and protein kinase C. The lipid/protein kinase, phosphoinositide-3 kinase also appears to play a key role, acting upstream of protein kinase C. In addition to the agents employed for cells stimulation, we observed that paracrine/autocrine mediators also participate; these processes include EGF transactivation and ...
We11,12 and others13-15 have shown that βAR stimulation in cardiac myocytes results in apoptosis that is mediated by ROS-dependent activation of JNK and the mitochondrial death pathway.16 This study demonstrates that βAR-stimulated JNK activation and apoptosis in ARVMs require Rac1. We further show for the first time that statins inhibit βAR-stimulated JNK activation and apoptosis and that these effects are due to inhibition of βAR-stimulated Rac1 activation.. A new finding of this study is that βAR stimulation causes Rac1 activation. Furthermore, adenoviral overexpression of the N17Rac1 dominant-negative mutant inhibited βAR-stimulated apoptosis and 3 known steps in the signaling pathway leading to βAR-stimulated apoptosis: JNK activation, cytochrome C release, and caspase-3 activation. Thus, in cardiac myocytes, βAR stimulation couples to Rac1 activation, which is upstream of JNK in the mitochondrial death pathway and necessary for βAR-stimulated apoptosis.. Little is known about the ...

The deubiquitinase ubiquitin-specific protease 20 is a positive modulator of myocardial β1-adrenergic receptor expression and signaling.
Similar to the scenario in neonatal rat cardiomyocytes, β1-AR stimulation with isoproterenol induces a robust increase in cAMP accumulation that is associated with an increase in the amplitude and an acceleration of the kinetics of both the calcium transient and the twitch in adult rat ventricular myocytes. In contrast, only rather high concentrations of the β2-AR agonist zinterol (10-5 mol/L) modulate contractile function in adult rat ventricular myocytes (Figure 2⇑). Parenthetically, 2 laboratories have presented data to support the theoretical argument that 10-5 mol/L zinterol (in the absence of a β1-AR blocker) acts as a mixed β1-/β2-AR agonist; β2-AR selectivity is achieved only if a β1-AR blocker (such as CGP 20712A) is included in the assay.11 73 In contrast, Xiao and Lakatta74 maintain that the effects of high concentrations of zinterol (even without a β1-AR blocker) are attributable entirely to the minor population of β2-ARs in the preparation, and they present results to ...

BACKGROUND--Failure of the donor (graft) heart is the main cause of mortality in the first month after orthotopic cardiac transplantation. In a preliminary study marked downregulation of cardiac beta adrenoceptor density was found in apparently normal donor hearts of recipients who developed severe cardiac failure soon after implantation. Cardiac beta adrenoceptors are an important factor in the development of cardiac failure in the human heart. The aim of this study therefore was to determine whether fatal graft failure in the first month after transplantation is associated with downregulation of beta adrenoceptor density in the donor heart. PATIENTS AND METHODS--Right ventricular endomyocardial biopsy specimens were taken from consecutive adult donor patients immediately before implantation. A previously described radioligand binding method was used to determine beta adrenoceptor density in consecutive patients who developed fatal graft failure and died within 1 month of transplantation and in ...

AU - Iwata, M.. AU - Wainai, Y.. AU - Suzuki, M.. AU - Ogawa, S.. PY - 2000/1/1. Y1 - 2000/1/1. N2 - Background: In vivo administration of norepinephrine fails to cause β-adrenergic receptor desensitization. However, short-term exposure of cultured cells to norepinephrine induces the phenomenon in vitro. We sought to identify the local regulatory mechanisms responsible for in vivo β-adrenergic receptor desensitization in congestive heart failure. Methods and Results: Control rabbits received norepinephrine (n = 7) or saline (n = 7) for 1 week, and rabbits with chemical denervation induced by 6-hydroxydopamine also received norepinephrine (n = 7) or saline (n = 7). Myocardial norepinephrine content decreased 80% in both groups of denervated rabbits. β1-Adrenergic receptor density in denervated ...
The alpha-2B adrenergic receptor (α2B adrenoceptor), is a G-protein coupled receptor. It is a subtype of the adrenergic receptor family. The human gene encoding this receptor has the symbol ADRA2B. ADRA2B orthologs have been identified in several mammals. α2-adrenergic receptors include 3 highly homologous subtypes: α2A, α2B, and α2C. These receptors have a critical role in regulating neurotransmitter release from sympathetic nerves and from adrenergic neurons in the central nervous system. This gene encodes the α2B subtype, which was observed to associate with eIF-2B, a guanine nucleotide exchange protein that functions in regulation of translation. A polymorphic variant of the α2B subtype, which lacks 3 glutamic acids from a glutamic acid repeat element, was identified to have decreased G protein-coupled receptor kinase-mediated phosphorylation and desensitization; this polymorphic form is also associated with reduced basal metabolic rate in obese subjects and may therefore contribute ...
