ATP as a presynaptic modulator [PDF]

open access: yes, 2000
© 2000 Elsevier Science Inc.There is considerable evidence that ATP acts as a fast transmitter or co-transmitter in autonomic and sensory nerves mostly through activation of ionotropic P2X receptors but also through metabotropic P2Y receptors. By analogy,

Dependence of Purinergic P2X Receptor Activity on Ectodomain Structure [PDF]

open access: yesJournal of Biological Chemistry, 2003
Purinergic receptors (P2XRs) activate and desensitize in response to the binding of extracellular nucleotides in a receptor- and ligand-specific manner, but the structural bases of their ligand preferences and channel kinetics have been incompletely characterized. Here we tested the hypothesis that affinity of agonists for binding domain accounts for a

Purinergic signaling in the modulation of redox biology

open access: yesRedox Biology, 2021
Purinergic signaling is a cell communication pathway mediated by extracellular nucleotides and nucleosides. Tri- and diphosphonucleotides are released in physiological and pathological circumstances activating purinergic type 2 receptors (P2 receptors ...

Expression of P2 receptors in human B cells and Epstein-Barr virus-transformed lymphoblastoid cell lines

open access: yesBMC Immunology, 2006
Background Epstein-Barr virus (EBV) infection immortalizes primary B cells in vitro and generates lymphoblastoid cell lines (LCLs), which are used for several purposes in immunological and genetic studies. Purinergic receptors, consisting of P2X and P2Y,

Purinergic Signaling During Hyperglycemia in Vascular Smooth Muscle Cells

open access: yesFrontiers in Endocrinology, 2020
The activation of purinergic receptors by nucleotides and/or nucleosides plays an important role in the control of vascular function, including modulation of vascular smooth muscle excitability, and vascular reactivity.

Purinergic receptor mediated calcium signalling in urothelial cells [PDF]

open access: yes, 2019
Non-neuronal ATP released from the urothelium in response to bladder stretch is a key modulator of bladder mechanosensation. Whilst non-neuronal ATP acts on the underlying bladder afferent nerves to facilitate sensation, there is also the potential for ...

Purinergic Receptors of the Central Nervous System: Biology, PET Ligands, and Their Applications

open access: yesMolecular Imaging, 2020
Purinergic receptors play important roles in central nervous system (CNS). These receptors are involved in cellular neuroinflammatory responses that regulate functions of neurons, microglial and astrocytes.

The adenosinergic machinery in cancer: In-tandem insights from basic mechanisms to therapy

open access: yesFrontiers in Immunology, 2023
Extracellular adenosine (eADO) signaling has emerged as an increasingly important regulator of immune responses, including tumor immunity. eADO is mainly produced from extracellular ATP (eATP) hydrolysis.

Pathophysiological Role of Extracellular Purinergic Mediators in the Control of Intestinal Inflammation

open access: yesMediators of Inflammation, 2015
Purinergic mediators such as adenosine 5′-triphosphate (ATP) are released into the extracellular compartment from damaged tissues and activated immune cells. They are then recognized by multiple purinergic P2X and P2Y receptors.

Purinergic Signaling in Mast Cell Degranulation and Asthma

open access: yesFrontiers in Pharmacology, 2017
Mast cells are responsible for the majority of allergic conditions. It was originally thought that almost all allergic events were mediated directly only via the high-affinity immunoglobulin E receptors.
