Purinergic Signalling: Therapeutic Developments [PDF]

open access: yesFrontiers in Pharmacology, 2017
Purinergic signalling, i.e., the role of nucleotides as extracellular signalling molecules, was proposed in 1972. However, this concept was not well accepted until the early 1990's when receptor subtypes for purines and pyrimidines were cloned and characterised, which includes four subtypes of the P1 (adenosine) receptor, seven subtypes of P2X ion ...

Purinergic signalling in systemic sclerosis

open access: yesRheumatology, 2021
Abstract SSc is a chronic autoimmune rheumatic disease that involves numerous organs and presents major management challenges. The histopathologic hallmarks of SSc include vasculopathy, fibrosis and autoimmune phenomena involving both innate and adaptive immune systems.

Sympathetic nerve-derived ATP regulates renal medullary vasa recta diameter via pericyte cells: a role for regulating medullary blood flow? [PDF]

open access: yes, 2013
Pericyte cells are now known to be a novel locus of blood flow control, being able to regulate capillary diameter via their unique morphology and expression of contractile proteins.

The role of purinergic signaling in microglial responses

open access: yesStress and Brain, 2021
Microglia, the primary immune cells in the central nervous system (CNS), are key to the maintenance of homeostasis in the brain parenchyma. In the intact brain, microglia continuously survey the microenvironment with ramified processes.

Purinergic Signaling in the Pathophysiology and Treatment of Huntington’s Disease

open access: yesFrontiers in Neuroscience, 2021
Huntington’s disease (HD) is a devastating, progressive, and fatal neurodegenerative disorder inherited in an autosomal dominant manner. This condition is characterized by motor dysfunction (chorea in the early stage, followed by bradykinesia, dystonia ...

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.

Emerging roles of purinergic signaling in anti-cancer therapy resistance

open access: yesFrontiers in Cell and Developmental Biology, 2022
Cancer is a complex disease with a rapid growing incidence and often characterized by a poor prognosis. Although impressive advances have been made in cancer treatments, resistance to therapy remains a critical obstacle for the improvement of patients ...

The relationship between P2X4 and P2X7: a physiologically important interaction? [PDF]

open access: yes, 2013
Purinergic signaling within the kidney is becoming an important focus in the study of renal health and disease. The effectors of ATP signaling, the P2Y and P2X receptors, are expressed to varying extents in and along the nephron.

P2X receptors: epithelial ion channels and regulators of salt and water transport. [PDF]

open access: yes, 2008
When the results from electrophysiological studies of renal epithelial cells are combined with data from in vivo tubule microperfusion experiments and immunohistochemical surveys of the nephron, the accumulated evidence suggests that ATP-gated ion ...

Integrating UHPLC-MS/MS quantitative analysis and exogenous purine supplementation to elucidate the antidepressant mechanism of Chaigui granules by regulating purine metabolism

open access: yesJournal of Pharmaceutical Analysis, 2023
Chaigui granules (CG) are a compound composed of six herbal medicines with significant antidepressant effects. However, the antidepressant mechanism of CG remains unclear. In the present study, we attempted to elucidate the antidepressant mechanism of CG
