ATP-Gated P2X Receptor Channels: Molecular Insights into Functional Roles.
Annual Review of Physiology, 2019 In the nervous system, ATP is co-stored in vesicles with classical transmitters and released in a regulated manner. ATP from the intracellular compartment can also exit the cell through hemichannels and following shear stress or membrane damage.

P2X receptors in neuroglia [PDF]
Wiley Interdisciplinary Reviews: Membrane Transport and Signaling, 2012 AbstractDifferent types of ionotropic P2X purinoceptors are expressed in all major types of neuroglia, where they mediate a variety of physiological and pathological signaling. Cortical astrocytes express specific P2X1/5 heteromeric receptors that are activated by ongoing synaptic transmission and can trigger fast local signaling through elevation in ...

BMC Cancer, 2009 Background The study tested the hypothesis that apoptosis can prevent and control growth of neoplastic cells. Previous studies in-vitro have shown that the pro-apoptotic P2X7 receptor regulates growth of epithelial cells.

Research progress in the role of P2X receptors in oral maxillofacial pain
口腔疾病防治, 2018 Oral maxillofacial pain is one of the most common symptoms that greatly influences patients′ quality of life. Infectious diseases, nerve injuries and tumors in the oromaxillofacial region can cause facial pain.

médecine/sciences, 2013 P2X purinergic receptors are receptors which, after ATP binding, form a channel permeant to monovalent and divalent cations. Acinar and ductal cells from salivary glands express P2X4 and P2X7 receptors. The P2X4 receptor has a high affinity for ATP, rapidly desensitizes and is mostly located on the basal membrane of acinar cells.

Introduction and perspective, historical note
Frontiers in Cellular Neuroscience, 2013 P2 nucleotide receptors were proposed to consist of two subfamilies based on pharmacology in 1985, named P2X and P2Y receptors. Later, this was confirmed following cloning of the receptors for nucleotides and studies of transduction mechanisms in the ...

Cellular Physiology and Biochemistry, 2016 Background/Aims: Published data suggest that purinergic P2X receptors of muscle afferent nerves contribute to the enhanced sympathetic nervous activity (SNA) and blood pressure (BP) responses during static exercise in heart failure (HF).

Subunit Arrangement in P2X Receptors [PDF]
The Journal of Neuroscience, 2003 ATP-gated ionotropic receptors (P2X receptors) are distributed widely in the nervous system. For example, a hetero-oligomeric receptor containing both P2X2and P2X3subunits is involved in primary afferent sensation. Each subunit has two membrane-spanning domains.

Molecular Pain, 2010 Background To evaluate whether P2X receptors are involved in responses to noxious pulp stimulation, the P2X3 and P2X2/3 receptor agonist α,β-methyleneATP (α,β-meATP) was applied to the molar tooth pulp and nocifensive behavior and extracellular-signal ...
