The dynamics of single spike-evoked adenosine release in the cerebellum [PDF]

open access: yes, 2010
The purine adenosine is a potent neuromodulator in the brain, with roles in a number of diverse physiological and pathological processes. Modulators such as adenosine are difficult to study as once released they have a diffuse action (which can affect ...

The Adenosinergic Signaling: A Complex but Promising Therapeutic Target for Alzheimer’s Disease

open access: yesFrontiers in Neuroscience, 2018
Alzheimer’s disease (AD) is the most common neurodegenerative disorder in elderly people. AD is characterized by a progressive cognitive decline and it is neuropathologically defined by two hallmarks: extracellular deposits of aggregated β-amyloid (Aβ ...

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.

Adenosine Dysfunction and Adenosine Kinase in Epileptogenesis [PDF]

open access: yesThe 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

Impulse oscillometry identifies peripheral airway dysfunction in children with adenosine deaminase deficiency. [PDF]

open access: yes, 2015
Adenosine deaminase-deficient severe combined immunodeficiency (ADA-SCID) is characterized by impaired T-, B- and NK-cell function. Affected children, in addition to early onset of infections, manifest non-immunologic symptoms including pulmonary ...

Mycobacterial adenosine kinase is not a typical adenosine kinase [PDF]

open access: yesFEBS Letters, 2009
Adenosine kinase (AK) is only found in eukaryotes. Recently, a Mycobacterium tuberculosis (MTub) protein exhibiting greater sequence similarity to ribokinases (RK) was identified as AK. We have expressed AKs from MTub, human and Chinese hamster (CH) cells in Escherichia coli and also AK from human and MTub in AK‐deficient CH cells. While both E.

Adenosine and Adenosine Receptors: Advances in Atrial Fibrillation

open access: yesBiomedicines, 2022
Atrial fibrillation (AF) is the most common arrhythmia in the world. Because the key to developing innovative therapies that limit the onset and the progression of AF is to fully understand the underlying molecular mechanisms of AF, the aim of the present narrative review is to report the most recent advances in the potential role of the adenosinergic ...

Adenosine A2a receptor promotes lymphangiogenesis and lymph node metastasis

open access: yesOncoImmunology, 2019
The formation of new lymphatic vessels, or lymphangiogenesis, is a critical step of the tissue repair program. In pathological conditions involving chronic inflammation or tumorigenesis, this process is often dysregulated and can contribute to disease ...

Adenosine Overcomes Triple-Negative Breast Cancer Resistance to Platinum-Derived Chemotherapeutic Drugs

open access: yesMedical Sciences Forum, 2022
Triple-negative breast cancer (TNBC), a poor survival cancer has high resistance to therapy, with low-drug efficacy. Adenosine is present in high concentrations in the tumor microenvironment.

Simultaneous quantification of 12 different nucleotides and nucleosides released from renal epithelium and in human urine samples using ion-pair reversed-phase HPLC [PDF]

open access: yes, 2012
Nucleotides and nucleosides are not only involved in cellular metabolism but also act extracellularly via P1 and P2 receptors, to elicit a wide variety of physiological and pathophysiological responses through paracrine and autocrine signalling pathways.
