It is a part of the DNA and the main degradation product of the central currency of energy metabolism in humans and animals – adenosine triphosphate (ATP). Under pathological conditions like hypoxia, the adenosine concentration can rise severalfold – up to micromolar concentrations. The net effect of adenosine on excitable tissue is inhibitory affecting the release of classical neurotransmitters like glutamate, GABA (gamma-aminobutyric acid), and dopamine. The widely used neurostimulant caffeine exerts its effects as an antagonist at adenosine receptors. Four different types of adenosine receptors have been described in mammals: A1, A2A, A2B, and A3 which are all G-protein-coupled receptors. Over the last 25 years, adenosine receptor ligands, agonists as well as antagonists, have emerged as a class of useful therapeutics. For the A1 and A2A subtypes several antagonist radioligands have been used successfully for PET imaging in humans and animals especially for the brain.}, cin = {INM-2 / INM-5}, cid = {I:(DE-Juel1)INM-2-20090406 / I:(DE-Juel1)INM-5-20090406}, pnm = {333 - Pathophysiological Mechanisms of Neurological and Psychiatric Diseases (POF2-333)}, pid = {G:(DE-HGF)POF2-333}, typ = {PUB:(DE-HGF)7}, doi = {10.1007/978-3-642-42014-6_7}, url = {https://juser.fz-juelich.de/record/151761}, }
