Adenosine and Adenosine Receptors
American Journal of Respiratory Cell and Molecular Biology, 1990In the last decade, there has been renewed interest in extracellular signaling by adenosine and adenine nucleotides. The potent cardiovascular effects of these agents were originally described by Drury and Szent-Gy6rgyi in 1929 (1). This report was followed by a flurry of interest in the use of adenosine as an antihypertensive agent, which subsided ...

Trends in Pharmacological Sciences, 1993
The numerous and widespread effects of adenosine provide both an opportunity for the development of novel therapeutic agents acting via adenosine receptors and the challenge of achieving selectivity of action. The feasibility of achieving selectivity is enhanced if receptor subtypes can be identified.

Adenosine receptors and their modulators
Pharmaceutica Acta Helvetiae, 1993The identification and characterization of adenosine receptors and the development of potent, receptor subtype-selective agonists and antagonists has been an active area of research for the past 20 years. Major recent advances in the field have been the cloning of several adenosine receptor subtypes of different species, including the discovery of a ...

Adenosine Receptors and Inflammation
2009Extracellular adenosine is produced in a coordinated manner from cells following cellular challenge or tissue injury. Once produced, it serves as an autocrine- and paracrine-signaling molecule through its interactions with seven-membrane-spanning G-protein-coupled adenosine receptors.

Adenosine and ATP Receptors in the Brain
Current Topics in Medicinal Chemistry, 2011There is a widespread presence of both adenosine (P1) and P2 nucleotide receptors in the brain on both neurones and glial cells. Adenosine receptors play a major role in presynaptic neuromodulation, while P2X receptors are involved in fast synaptic transmission and synaptic plasticity. P2Y receptors largely mediate presynaptic activities.

Abstract Adenosine is not a neurotransmitter but rather a paracrine neuromodulator. This obviously does not mean that adenosine is not biologically important—it just means that we must think differently about its role compared to, for example, dopamine or noradrenaline.

Adenosine receptors and their ligands
Naunyn-Schmiedeberg's Archives of Pharmacology, 2000The regulatory actions of adenosine are mediated via four subtypes of G protein-coupled receptors distinguished as A1, A2A, A2B and A3 receptors. Their presence on basically every cell makes them an interesting target for the pharmacological intervention in many pathophysiological situations.

Adenosine and ATP, via P1 and P2 receptors respectively, can modulate pain transmission under physiological, inflammatory, and neuropathic pain conditions. Such influences reflect peripheral and central actions and effects on neurons as well as other cell types.

Adenosine Receptors on Human Lymphocytes
1986Evidence is accumulating that adenosine functions as an important immunoregulatory autacoid (1,2). Adenosine inhibits the mitotic response of human lymphocytes (3,4), lymphocyte-mediated cytolysis (5), superoxide anion generation by neutrophils (6), platelet aggregation (7) and mediator release from human basophils (8-10). The nucleoside has been shown
