A depletable pool of adenosine in area CA1 of the rat hippocampus [PDF]

, 2001
Adenosine plays a major modulatory and neuroprotective role in the mammalian CNS. During cerebral metabolic stress, such as hypoxia or ischemia, the increase in extracellular adenosine inhibits excitatory synaptic transmission onto vulnerable neurons via

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,

Adenosine-Related Mechanisms in Non-Adenosine Receptor Drugs

Cells, 2020
Many ligands directly target adenosine receptors (ARs). Here we review the effects of noncanonical AR drugs on adenosinergic signaling. Non-AR mechanisms include raising adenosine levels by inhibiting adenosine transport (e.g., ticagrelor, ethanol, and ...

A population of immature cerebellar parallel fibre synapses are insensitive to adenosine but are inhibited by hypoxia [PDF]

, 2011
The purine adenosine plays an important role in a number of physiological and pathological processes and is neuroprotective during hypoxia and ischemia.

ATP- and Adenosine-Mediated Signaling in the Central Nervous System: Adenosine Receptor Activation by ATP Through Rapid and Localized Generation of Adenosine by Ecto-nucleotidases

Journal of Pharmacological Sciences, 2004
Extracellular ATP is now recognized as a neurotransmitter or neuromodilator in the nervous system, producing diverse physiological effects by activating multiple P2 receptors.

Upregulation of inducible NO synthase by exogenous adenosine in vascular smooth muscle cells activated by inflammatory stimuli in experimental diabetes [PDF]

, 2016
BACKGROUND: Adenosine has been shown to induce nitric oxide (NO) production via inducible NO synthase (iNOS) activation in vascular smooth muscle cells (VSMCs). Although this is interpreted as a beneficial vasodilating pathway in vaso-occlusive disorders,

Adenosine Receptors and Cancer [PDF]

, 2009
The A(1), A(2A), A(2B) and A(3) G-protein-coupled cell surface adenosine receptors (ARs) are found to be upregulated in various tumor cells. Activation of the receptors by specific ligands, agonists or antagonists, modulates tumor growth via a range of signaling pathways.

Hypoxia-inducible factor 1-dependent expression of adenosine receptor 2B promotes breast cancer stem cell enrichment

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance In order for a single breast cancer cell to form a recurrent tumor after therapy or a metastasis at a distant site such as the lung, it must have the properties of a breast cancer stem cell. In this paper, we show that adenosine receptor 2B (

Discovery of benzothiazolylquinoline conjugates as novel human A3 receptor antagonists: biological evaluations and molecular docking studies [PDF]

Royal Society Open Science, 2018
Adenosine is known as an endogenous purine nucleoside and it modulates a wide variety of physiological responses by interacting with adenosine receptors. Among the four adenosine receptor subtypes, the A3 receptor is of major interest in this study as it

Anti-Hair Loss Effect of Adenosine Is Exerted by cAMP Mediated Wnt/β-Catenin Pathway Stimulation via Modulation of Gsk3β Activity in Cultured Human Dermal Papilla Cells

Molecules, 2022
In the present study, we investigated the molecular mechanisms of adenosine for its hair growth promoting effect. Adenosine stimulated the Wnt/β-catenin pathway by modulating the activity of Gsk3β in cultured human dermal papilla cells. It also activated
