Objectives: The aim of the present study was to analyze whether beta3-adrenoceptors (β3-
ARs) were effectively present and functional in the human internal mammary artery (IMA) …

[alpha]-Adrenoceptor agonists and antagonists are widely used perioperatively for internal
mammary artery (IMA)-coronary artery bypass operations. To determine subtypes of a …

Objectives: The goal was to identify alpha-1-adrenergic receptor (AR) subtypes in human
coronary arteries. Background: The α1-ARs regulate human coronary blood flow. The α1 …

The sympathetic nervous system is central for the neurohumoral regulation of the
cardiovascular system and is largely involved in many cardiovascular diseases affecting …

Background—Coronary vessel tone is modulated in part by β-adrenergic relaxation.
However, the implication of specific β-adrenoceptor subtypes and their downstream …

The internal mammary artery (IMA) is currently the preferred conduit for myocardial
revascularization. However, perioperative vasospasm and a hypoperfusion state during …

Catecholamines released by the orthosympathetic system play a major role in the short-and
long-term regulation of cardiovascular function. Beta1-and beta2-adrenoreceptors (ARs) …

We have previously demonstrated that β3‐adrenoceptor (β3‐AR) stimulation induces
endothelium‐dependent vasorelaxation in rat aorta through the activation of an endothelial …

The third isotype of beta-adrenoreceptors (β3-AR) has recently come (back) into focus after
the observation of its expression in white and beige human adipocytes and its implication in …

Abstract Alpha-1-adrenergic receptors (α1-ARs) regulate coronary arterial blood flow by
binding catecholamines, norepinephrine (NE), and epinephrine (EPI), causing …
