Frontiers in Immunology, 2022 Adenosine is a purine nucleoside that, via activation of distinct G protein-coupled receptors, modulates inflammation and immune responses. Under pathological conditions and in response to inflammatory stimuli, extracellular ATP is released from damaged ...

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,

Extracellular adenosine triphosphate and adenosine in cancer [PDF]
Oncogene, 2010 Adenosine triphosphate (ATP) is actively released in the extracellular environment in response to tissue damage and cellular stress. Through the activation of P2X and P2Y receptors, extracellular ATP enhances tissue repair, promotes the recruitment of immune phagocytes and dendritic cells, and acts as a co-activator of NLR family, pyrin domain ...

Frontiers in Neuroscience, 2020 Background and Purpose: Adenosine dysregulation is associated with the occurrence of the epilepsy and equilibrative nucleoside transporters-1 (ENT-1) functions as an important regulator of extracellular adenosine in the brain.

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

Frontiers in Physiology, 2022 The spontaneous action potential (AP) firing rate of sinoatrial nodal cells (SANC) is regulated by a system of intracellular Ca2+ and membrane ion current clocks driven by Ca2+-calmodulin-activated adenylyl cyclase-protein kinase-A signaling. The mean AP-

Expanding a fluorescent RNA alphabet: synthesis, photophysics and utility of isothiazole-derived purine nucleoside surrogates. [PDF]
, 2017 A series of emissive ribonucleoside purine mimics, all comprised of an isothiazolo[4,3-d]pyrimidine core, was prepared using a divergent pathway involving a key Thorpe-Ziegler cyclization.

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.

Adenosine and adenosine antagonism in asthma [PDF]
Thorax, 1998 I read with interest the excellent update on adenosine by Polosa and Holgate.1 An important use of this challenge agent is demonstrated and adenosine antagonism as a potential treatment for asthma is revisited. However, the role of adenosine as a mediator of asthma is somewhat inconsistent with several functional observations.
