Pericyte-mediated regulation of capillary diameter: a component of neurovascular coupling in health and disease [PDF]

open access: yes, 2010
Because regional blood flow increases in association with the increased metabolic demand generated by localised increases in neural activity, functional imaging researchers often assume that changes in blood flow are an accurate read-out of changes in ...

Effect of diabetes/hyperglycemia on the rat retinal adenosinergic system. [PDF]

open access: yesPLoS ONE, 2013
The early stages of diabetic retinopathy (DR) are characterized by alterations similar to neurodegenerative and inflammatory conditions such as increased neural apoptosis, microglial cell activation and amplified production of pro-inflammatory cytokines.

Therapeutic potential of adenosine kinase inhibition-Revisited. [PDF]

open access: yesPharmacol Res Perspect, 2019
AbstractAdenosine (ADO) is an endogenous protective regulator that restores cellular energy balance in response to tissue trauma. Extracellular ADO has a half‐life of the order of seconds thus restricting its actions to tissues and cellular sites where it is released.

Modulation of plant growth in vivo and identification of kinase substrates using an analog-sensitive variant of CYCLIN-DEPENDENT KINASE A;1 [PDF]

open access: yes, 2016
BACKGROUND: Modulation of protein activity by phosphorylation through kinases and subsequent de-phosphorylation by phosphatases is one of the most prominent cellular control mechanisms.

In vitro biosynthesis of ATP from adenosine and polyphosphate

open access: yesBioresources and Bioprocessing, 2021
Adenosine triphosphate (ATP) acts as a crucial energy currency in vivo, and it is a widely used energy and/or phosphate donor for enzyme-catalyzed reactions in vitro.

Adenosine Kinase Mediates High Affinity Adenosine Salvage in Trypanosoma brucei [PDF]

open access: yesJournal of Biological Chemistry, 2008
African sleeping sickness is caused by Trypanosoma brucei. This extracellular parasite lacks de novo purine biosynthesis, and it is therefore dependent on exogenous purines such as adenosine that is taken up from the blood and other body fluids by high affinity transporters. The general belief is that adenosine needs to be cleaved to adenine inside the

Regulation of peripheral inflammation by spinal p38 MAP kinase in rats. [PDF]

open access: yes, 2006
BackgroundSomatic afferent input to the spinal cord from a peripheral inflammatory site can modulate the peripheral response. However, the intracellular signaling mechanisms in the spinal cord that regulate this linkage have not been defined.

Regulation of endothelial intracellular adenosine via adenosine kinase epigenetically modulates vascular inflammation

open access: yesNature Communications, 2017
The molecular mechanisms underlying vascular inflammation are unclear. Here the authors show that pro-inflammatory stimuli lead to endothelial inflammation by increasing adenosine kinase expression, and that its knockdown in endothelial cells inhibits ...

Cyclic AMP signalling in pancreatic islets [PDF]

open access: yes, 2010
Cyclic 3'5'AMP (cAMP) is an important physiological amplifier of glucose-induced insulin secretion by the pancreatic islet β-cell, where it is formed by the activity of adenylyl cyclases, which are stimulated by glucose, through elevation in ...
