ATP, UTP, ADP and ADP‐β‐S elicited Ca2+‐signals in cultured aortic smooth muscle cells
although ADP, UDP and ADP‐β‐S gave∼ 40% of the maximal response seen with ATP and …

Effects of extraluminal UTP were studied and compared with vascular responses to ATP and
its analogs in rat cerebral-penetrating arterioles. UTP, UDP, 2-methylthio-ATP, and α, β …

The dilator effect of extracellular adenosine triphosphate (ATP) has mainly been
characterized as a direct effect on smooth muscle or as an endothelium‐dependent effect …

It has recently been demonstrated that two types of ATP receptors, the P2y and P2u
receptors, are coexpressed on bovine aortic endothelial cells. The aim of the present study …

Mitogenic effects of the extracellular nucleotides ATP and UTP are mediated by P2Y1, P2Y2,
and P2Y4 receptors. However, it has not been possible to examine the highly expressed …

Background and purpose: P2Y receptors evoke Ca2+ signals in vascular smooth muscle
cells and regulate contraction and proliferation, but the roles of the different P2Y receptor …

Objective—A solid body of evidence supports a role of extracellular ATP and its P2 receptors
in innate and adaptive immunity. It promotes inflammation as a danger signal in various …

1 Vasoconstrictor responses of the isolated and perfused canine epicardial coronary artery
to uridine 5′‐triphosphate (UTP) were analysed pharmacologically. 2 At basal perfusion …

Extracellular nucleotides have been shown to induce vasodilatation of conductance arteries
by release of the endothelium‐derived hyperpolarizing factor (EDHF). As small resistance …
