Evidence for coordinated induction and repression of ecto-5'-nucleotidase (CD73) and the A2a adenosine receptor in a human B cell line [PDF]

open access: yes, 2003
In the human B cell line P493-6 two mitogenic signals, the EpsteinBarr virus nuclear antigen 2 (EBNA2) and myc, can be independently regulated by means of an estrogen receptor fusion construct or an inducible expression vector, respectively.

Adenosine regulation of the immune system

open access: yes, 2018
Adenosine is an endogenous nucleoside, released into the extracellular space in response to metabolic stress and cell damage and critically involved in the maintenance of tissue integrity by modulation of the immune system.

Biosensor measurement of purine release from cerebellar cultures and slices [PDF]

open access: yes, 2010
We have previously described an action-potential and Ca2+-dependent form of adenosine release in the molecular layer of cerebellar slices. The most likely source of the adenosine is the parallel fibres, the axons of granule cells. Using microelectrode

Activation of Adenylyl Cyclase Causes Stimulation of Adenosine Receptors

open access: yesCellular Physiology and Biochemistry, 2018
Background/Aims: Signaling of Gs protein-coupled receptors (GsPCRs) is accomplished by stimulation of adenylyl cyclase, causing an increase of the intracellular cAMP concentration, activation of the intracellular cAMP effectors protein kinase A (PKA) and

Models for the PET quantitative imaging of the adenosine receptor radioligand [11C] SCH442416 in humans [PDF]

open access: yes, 2010
Positron Emission Tomography is an important imaging technique, that enables regional function to be assayed in a fully quantitative and noninvasive manner. It is based on the use of radioactive tracers: [11C]SCH442416, which is the compound of interest

Unlocking the adenosine receptor mechanism of the tumour immune microenvironment

open access: yesFrontiers in Immunology
The suppressive tumour microenvironment significantly hinders the efficacy of immunotherapy in treating solid tumors. In this context, stromal cells, such as tumour-associated fibroblasts, undergo changes that include an increase in the number and ...

Endothelial and Neuronal Nitric Oxide Activate Distinct Pathways on Sympathetic Neurotransmission in Rat Tail and Mesenteric Arteries. [PDF]

open access: yesPLoS ONE, 2015
Nitric oxide (NO) seems to contribute to vascular homeostasis regulating neurotransmission. This work aimed at assessing the influence of NO from different sources and respective intracellular pathways on sympathetic neurotransmission, in two vascular ...

Adenosine receptors and reperfusion injury of the heart

open access: yes, 2009
Adenosine, a catabolite of ATP, exerts numerous effects in the heart, including modulation of the cardiac response to stress, such as occurs during myocardial ischemia and reperfusion.

Adenosine Receptors and Wound Healing, Revised

open access: yesThe Scientific World Journal, 2006
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 ...

Purinergic Receptors in Adipose Tissue As Potential Targets in Metabolic Disorders

open access: yesFrontiers in Pharmacology, 2017
Extracellular nucleosides and nucleotides, such as adenosine and adenosine triphosphate (ATP), are involved in many physiological and pathological processes in adipose tissue (AT).
