Adenosine is directly linked to the energy metabolism of cells. In the central nervous system an increase in neuronal activity enhances energy consumption as well as extracellular adenosine concentrations. In most brain areas high extracellular adenosine concentrations, through A(1) adenosine receptors, decrease neuronal activity and thus the need for ...

Annual Review of Physiology, 1992
Our knowledge of A1 and A2ARs has grown dramatically since they were first defined by Burnstock. With the recent purification of the A1AR and the cDNA cloning of the A2AR, an even more rapid expansion of information regarding their structure, function, and regulation should now ensue.

Pharmacotherapy: The Journal of Human Pharmacology and Drug Therapy, 1990
Adenosine is a purine nucleoside present in every cell of the human body. It is released into the extracellular space under physiologic and pathophysiologic conditions characterized by increased oxygen demand: supply ratio. Adenosine can exert a wide spectrum of effects in various organs and tissues.

Adenosine Diphosphate, Adenosine Triphosphate
1955The increasing importance for animals and bacteria of adenosine diphosphate (ADP) and adenosine triphosphate (ATP) in energy-transfer mechanisms involving such widely diverse processes as muscular contraction, nerve conduction, fire fly luminescence, coenzyme syntheses, tumor growth, polysaccharide synthesis and many other key reactions (McElroy and ...

[Adenosine and adenosine receptors in the kidney].
Nihon rinsho. Japanese journal of clinical medicine, 1993In the kidney, adenosine plays important regulatory roles, including renal blood flow, glomerular filtration rate, renin secretion, tubuloglomerular feedback, tubular reabsorption of sodium and water, sympathetic neurotransmitter release, and erythropoietin secretion.

Immunohistochemistry of Adenosine Deaminase: Implications for Adenosine Neurotransmission
Science, 1984Immunohistochemical analysis of adenosine deaminase in rat brain revealed an extensive plexus of adenosine deaminase-containing neurons in the basal hypothalamus. These neurons converged on and were most numerous in three major centers, namely, the tuberal, caudal, and postmammillary caudal magnocellular nuclei.

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, adenosine receptors and glaucoma: An updated overview
Biochimica et Biophysica Acta (BBA) - General Subjects, 2013Glaucoma, a leading cause of blindness worldwide, is an optic neuropathy commonly associated with elevated intraocular pressure (IOP). The major goals of glaucoma treatments are to lower IOP and protect retinal ganglion cells. It has been revealed recently that adenosine and adenosine receptors (ARs) have important roles in IOP modulation and ...

The classic endogenous somnogen adenosine promotes sleep via A1 and A2A receptors. In this chapter, we present an overview of the current knowledge regarding the regulation of adenosine levels, adenosine receptors, and available pharmacologic and genetic tools to manipulate the adenosine system. This is followed by a summary of current knowledge of the
