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

open access: yes, 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

Adenosine receptors and cancer

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2011
Adenosine is a ubiquitous signaling molecule whose physiological functions are mediated by its interaction with four G-protein-coupled receptor subtypes, termed A(1), A(2A), A(2B) and A(3). As a result of increased metabolic rates, this nucleoside is released from a variety of cells throughout the body in concentrations that can have a profound impact ...

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

open access: yes, 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 ...

Adenosine Receptor-Mediated Cardioprotection—Current Limitations and Future Directions

open access: yesFrontiers in Pharmacology, 2018
Since the seminal reports of adenosine receptor-mediated cardioprotection in the early 1990s, there have been a multitude of such reports in various species and preparations.

The implication of adenosine receptor expression in prediction of methotrexate clinical response in Egyptian rheumatoid arthritis patients

open access: yesEgyptian Rheumatology and Rehabilitation, 2022
Background Adenosine signaling is now an accepted explanation for the therapeutic mechanism of Methotrexate (MTX) in rheumatoid arthritis (RA). Adenosine receptors categorized into four subclasses: adenosine A1 receptor (ADORA1), adenosine 2a receptor ...

Adenosine Receptors and the Kidney [PDF]

open access: yes, 2009
The autacoid, adenosine, is present in the normoxic kidney and generated in the cytosol as well as at extracellular sites. The rate of adenosine formation is enhanced when the rate of ATP hydrolysis prevails over the rate of ATP synthesis during increased tubular transport work or during oxygen deficiency.

Dual acting antioxidant A1 adenosine receptor agonists [PDF]

open access: yes, 2007
Herein we report the synthesis and biological evaluation of some potent and selective A1 adenosine receptor agonists, which incorporate a functionalised linker attached to an antioxidant moiety.

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

open access: yesImmunity & 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.

Adenosine Receptors and Asthma [PDF]

open access: yes, 2009
The pathophysiological processes underlying respiratory diseases like asthma are complex, resulting in an overwhelming choice of potential targets for the novel treatment of this disease. Despite this complexity, asthmatic subjects are uniquely sensitive to a range of substances like adenosine, thought to act indirectly to evoke changes in respiratory ...

Adenosine Receptors and Wound Healing

open access: yesThe 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 ...
