Wakefulness affects synaptic and network activity by increasing extracellular astrocyte-derived adenosine [PDF]

, 2012
Loss of sleep causes an increase in sleep drive and deficits in hippocampal-dependent memory. Both of these responses are thought to require activation of adenosine A1 receptors (adorA1Rs) and release of transmitter molecules including ATP, which is ...

Adenosine and Migraine [PDF]

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 1998
ABSTRACT:Background:Adenosine is a powerful natural vasodilator that participates in the control of cerebral and meningeal blood flow. In this context, it could be involved in the pathophysiology of migraine, since it was previously reported that intravenous adenosine can precipitate crises in migraine patients.Methods:We have investigated circulating ...

Intracellular ATP influences synaptic plasticity in area CA1 of rat hippocampus via metabolism to adenosine and activity-dependent activation of adenosine A1 receptors [PDF]

, 2011
The extent to which brain slices reflect the energetic status of the in vivo brain has been a subject of debate. We addressed this issue to investigate the recovery of energetic parameters and adenine nucleotides in rat hippocampal slices and the ...

Treatment With Methotrexate Associated With Lipid Core Nanoparticles Prevents Aortic Dilation in a Murine Model of Marfan Syndrome

Frontiers in Cardiovascular Medicine, 2022
In Marfan syndrome (MFS), dilation, dissection, and rupture of the aorta occur. Inflammation can be involved in the pathogenicity of aortic defects and can thus be a therapeutic target for MFS.

Adenosine Dysfunction and Adenosine Kinase in Epileptogenesis [PDF]

The Open Neuroscience Journal, 2010
Traditionally, epilepsy has been considered to be a disorder of neuronal dysfunction. Based on this dogma, drug development efforts have largely focused on neurocentric model systems to screen for compounds that affect the function of neurons. Unfortunately, about 30% of all patients with epilepsy - or more than 20 million worldwide - are refractory to

Photoresponsive adenosine derivatives for optical control of adenosine A2A receptor in living cells [PDF]

, 2023
Subtype-selective ligands with photoswitchable properties are highly desired for photopharmacology of G protein-coupled receptors (GPCRs). We developed photoswitchable ligands targeting adenosine A2A receptor (A2AR), a GPCR subtype.

Adenosine triphosphate as a modulator of protein interactions and stability. [PDF]

FEBS Open Bio
ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

Adenosine and Sleep [PDF]

Current Neuropharmacology, 2009
Over the last several decades the idea that adenosine (Ado) plays a role in sleep control was postulated due in large part to pharmacological studies that showed the ability of Ado agonists to induce sleep and Ado antagonists to decrease sleep. A second wave of research involving in vitro cellular analytic approaches and subsequently, the use of ...

Adenosine in fibrosis [PDF]

Modern Rheumatology, 2010
Adenosine is an endogenous autocoid that regulates a multitude of bodily functions. Its anti-inflammatory actions are well known to rheumatologists since it mediates many of the anti-inflammatory effects of a number of antirheumatic drugs such as methotrexate.
