Synergistic Effects of Adenosine A2A Antagonist and L-DOPA on Rotational Behaviors in 6-Hydroxydopamine-Induced Hemi-Parkinsonian Mouse Model

Journal of Pharmacological Sciences, 2007
In this study, we examined the combination effects of L-DOPA and adenosine receptor antagonists on rotational behaviors in a hemi-Parkinsonian mouse model induced by unilateral 6-hydroxydopamine (6-OHDA) injection. The adenosine A2A antagonist SCH-58261,

CD73-A2a adenosine receptor axis promotes innate B cell antibody responses to pneumococcal polysaccharide vaccination. [PDF]

PLoS ONE, 2018
Many individuals at risk of streptococcal infection respond poorly to the pneumococcal polysaccharide vaccine Pneumovax 23. Identification of actionable pathways able to enhance Pneumovax responsiveness is highly relevant.

Agonist-bound adenosine A2A receptor structures reveal common features of GPCR activation

Nature, 2011
Adenosine receptors and β-adrenoceptors are G-protein-coupled receptors (GPCRs) that activate intracellular G proteins on binding the agonists adenosine or noradrenaline, respectively.

Adenosine A_2A receptor binding profile of two antagonists, ST1535 and KW6002: consideration on the presence of atypical adenosine A_2A binding sites

Frontiers in Psychiatry, 2010
Adenosine A2A receptors seem to exist in typical (more in striatum) and atypical (more in hippocampus and cortex) subtypes. In the present study, we investigated the affinity of two adenosine A2A receptor antagonists, ST1535 [2 butyl -9-methyl-8-(2H-1,2 ...

Adenosine A2A receptor antagonists: from caffeine to selective non‐xanthines

British Journal of Pharmacology, 2020
A long evolution of knowledge of the psychostimulant caffeine led in the 1960s to another purine natural product, adenosine and its A2A receptor. Adenosine is a short‐lived autocrine/paracrine mediator that acts pharmacologically at four different ...

Adenosine Receptors and Wound Healing

The Scientific World Journal, 2004
Recent studies have demonstrated that application of topical adenosine A2A receptor agonists promotes more rapid wound closure and clinical studies are currently underway to determine the utility of topical A2A adenosine receptor agonists in the therapy ...

Low expression of CD39 and CD73 genes in centenarians compared with octogenarians

Immunity & Ageing, 2017
Ageing involves a progressive decline of the body’s regulatory systems including immune system. Adenosine regulates immune function by interaction with its receptors, mainly adenosine A2A receptor, present on the surface of immune cells.

Structure of the adenosine A2A receptor bound to an engineered G protein

Nature, 2016
G-protein-coupled receptors (GPCRs) are essential components of the signalling network throughout the body. To understand the molecular mechanism of G-protein-mediated signalling, solved structures of receptors in inactive conformations and in the active

ATP- and Adenosine-Mediated Signaling in the Central Nervous System: Adenosine Stimulates Glutamate Release From Astrocytes via A2a Adenosine Receptors

Journal of Pharmacological Sciences, 2004
Adenosine enhanced intracellular Ca2+ concentrations in astrocytes via A2a adenosine receptors involving protein kinase A (PKA) activation. The Ca2+ rise is inhibited by brefeldin A, an inhibitor of vesicular transport; but not by neomycin and U73122 ...
