Purines and Carotid Body: New Roles in Pathological Conditions

open access: yesFrontiers in Pharmacology, 2017
It is known that adenosine and adenosine-5′-triphosphate (ATP) are excitatory mediators involved in carotid body (CB) hypoxic signaling. The CBs are peripheral chemoreceptors classically defined by O2, CO2, and pH sensors.

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

open access: yes, 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,

Inosine as a Tool to Understand and Treat Central Nervous System Disorders: A Neglected Actor?

open access: yesFrontiers in Neuroscience, 2021
Since the 1970s, when ATP was identified as a co-transmitter in sympathetic and parasympathetic nerves, it and its active metabolite adenosine have been considered relevant signaling molecules in biological and pathological processes in the central ...

Stimulation of endothelial adenosine Al receptors enhances adhesion of neutrophils in the intact guinea pig coronary system [PDF]

open access: yes, 1994
Objective: The primary aim was to determine the action of pathophysiologically relevant adenosine concentrations (0.1-1 μM) on adhesion of neutrophils to coronary endothelium.

A3 Adenosine Receptors Modulate Hypoxia-inducible Factor-1a Expression in Human A375 Melanoma Cells

open access: yesNeoplasia: An International Journal for Oncology Research, 2005
Hypoxia-inducible factor-1 (HIF-1) is a key regulator of genes crucial to many aspects of cancer biology. The purine nucleoside, adenosine, accumulates within many tissues under hypoxic conditions, including that of tumors. Because the levels of both HIF-

Adenosine and adenosine antagonism in asthma [PDF]

open access: yesThorax, 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.

Adenosine and preeclampsia [PDF]

open access: yesMolecular Aspects of Medicine, 2017
Adenosine is an endogenous nucleoside with pleiotropic effects in different physiological processes including circulation, renal blood flow, immune function, or glucose homeostasis. Changes in adenosine membrane transporters, adenosine receptors, and corresponding intracellular signalling network associate with development of pathologies of pregnancy ...

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

Effects of Adenosine Extract from Pholiota adiposa (Fr.) Quel on mRNA Expressions of Superoxide Dismutase and Immunomodulatory Cytokines

open access: yesMolecules, 2013
Pholiota adiposa is a kind of edible mushroom which has long been known for its health care applications. To reveal the exact mechanism of its protective functions in humans, in this study we isolated and identified the active compound PB3 of P.

Safety profile of adenosine stress cardiac MRI in a tertiary hospital in India

open access: yesIndian Journal of Radiology and Imaging, 2020
Background: Coronary artery disease (CAD) is a major cause of morbidity and mortality in India. Stress Cardiac Magnetic Resonance (CMR) using vasodilator agent is well established in assessing the functional significance of CAD.
