Dual control of vascular tone and remodelling by ATP released from nerves and endothelial cells [PDF]

open access: yes, 2008
Purinergic signalling is important both in short-term control of vascular tone and in longer-term control of cell proliferation, migration and death involved in vascular remodelling.

Pharmacological characterization of P2X1 and P2X3 purinergic receptors in bovine chondrocytes [PDF]

open access: yes, 2008
SummaryObjectiveThe aim of the present study is that of characterizing, for the first time in a quantitative way, from a biochemical, physico chemical and functional point of view P2X1 and P2X3 purinergic receptors in bovine chondrocytes.

Purinergic Receptors in Neurological Diseases With Motor Symptoms: Targets for Therapy

open access: yesFrontiers in Pharmacology, 2018
Since proving adenosine triphosphate (ATP) functions as a neurotransmitter in neuron/glia interactions, the purinergic system has been more intensely studied within the scope of the central nervous system.

Exosome as bioactive nanovesicle for diagnostic and therapeutic applications in periodontitis

open access: yesBMEMat, EarlyView.
This review introduces the mechanism that exosomes participate in the pathogenesis of periodontitis and their potential as biomarkers for early diagnosis and summarizes the application of cell‐ or plant‐derived exosomes or engineered exosomes in periodontitis or periodontal regeneration while proposing the perspective of translational application of ...

Enhancing antitumor immunity through the combination of cholesterolized TLR7 agonist liposomes and radiotherapy: a role for IL‐1β and the inflammasome pathway

open access: yesCancer Communications, EarlyView.
Abstract Background Radiotherapy (RT) is a key treatment modality in cancer therapy, utilizing high‐energy radiation to directly kill tumor cells. Recent research has increasingly highlighted RT's potential to indirectly enhance antitumor immunity. However, this immune activation alone often fails to generate sustained systemic antitumor responses.

Resetting intrinsic purinergic modulation of neural activity: an associative mechanism? [PDF]

open access: yes, 2002
The purines, ATP and adenosine, control the rundown and termination of swimming in the Xenopus embryo. This intrinsic purinergic modulation, unavoidably present during every swimming episode, could lead to stereotyped inflexible behavior and consequently

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

SARS-CoV-2 Spike protein alters microglial purinergic signaling

open access: yesFrontiers in Immunology, 2023
Despite long-term sequelae of COVID-19 are emerging as a substantial public health concern, the mechanism underlying these processes still unclear. Evidence demonstrates that SARS-CoV-2 Spike protein can reach different brain regions, irrespective of ...

P2X1 and P2X5 subunits form the functional P2X receptor in mouse cortical astrocytes [PDF]

open access: yes, 2008
ATP plays an important role in signal transduction between neuronal and glial circuits and within glial networks. Here we describe currents activated by ATP in astrocytes acutely isolated from cortical brain slices by non-enzymatic mechanical ...

Purinergic receptors P2RX4 and P2RX7 in familial multiple sclerosis

open access: yesHuman Mutation, 2017
Genetic variants in the purinergic receptors P2RX4 and P2RX7 have been shown to affect susceptibility to multiple sclerosis (MS). In this study, we set out to evaluate whether rare coding variants of major effect could also be identified in these ...
