Transmission to interneurons is via slow excitatory synaptic potentials mediated by P2Y(1) receptors during descending inhibition in guinea-pig ileum. [PDF]

PLoS ONE, 2013
BACKGROUND: The nature of synaptic transmission at functionally distinct synapses in intestinal reflex pathways has not been fully identified. In this study, we investigated whether transmission between interneurons in the descending inhibitory pathway ...

P2Y receptors in bone [PDF]

Wiley Interdisciplinary Reviews: Membrane Transport and Signaling, 2012
AbstractBones are formed and remodeled by the coordinated actions of three key cell types. Osteoblasts, specialized connective tissue cells, deposit and then mineralize the collagenous bone matrix. Osteoclasts, which are derived from promonocytes, resorb mineralized matrix by excavating characteristic pits on bone surfaces.

The potential for biased signalling in the P2Y receptor family of GPCRs

British Journal of Pharmacology, EarlyView.
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora

Purinergic Receptors in Spinal Cord-Derived Ependymal Stem/Progenitor Cells and Their Potential Role in Cell-Based Therapy for Spinal Cord Injury

Cell Transplantation, 2015
Spinal cord injury (SCI) is a major cause of paralysis with no current therapies. Following SCI, large amounts of ATP and other nucleotides are released by the traumatized tissue leading to the activation of purinergic receptors that, in coordination ...

TMEM16A channel signalling microdomains in the regulation of vascular function

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,

Role of P2 Receptors as Modulators of Rat Eosinophil Recruitment in Allergic Inflammation. [PDF]

PLoS ONE, 2016
ATP and other nucleotides are released from cells through regulated pathways or following the loss of plasma membrane integrity. Once outside the cell, these compounds can activate P2 receptors: P2X ionotropic receptors and G protein-coupled P2Y ...

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

Myocardial stretch‐induced ROS production is enhanced prior to the development of heart failure under TAC‐induced pressure overload

The Journal of Physiology, EarlyView.
Abstract figure legend To elucidate the relationship between oxidative stress in heart failure induced by chronic mechanical overload and physiological NOX2‐derived stretch‐induced reactive oxygen species (ROS) that support myocardial contractility during acute stretch, we investigated the changes in stretch‐induced ROS following transverse aortic ...

Gi- and Gq-coupled ADP (P2Y) receptors act in opposition to modulate nociceptive signaling and inflammatory pain behavior

Molecular Pain, 2010
Background Investigations of nucleotide signaling in nociception to date have focused on actions of adenosine triphosphate (ATP). Both ATP-gated ion channels (P2X receptors) and G protein-coupled (P2Y) receptors contribute to nociceptive signaling in ...

NCI-H295R, a human adrenal cortex-derived cell line, expresses purinergic receptors linked to Ca²⁺-mobilization/influx and cortisol secretion. [PDF]

PLoS ONE, 2013
Purinergic receptor expression and involvement in steroidogenesis were examined in NCI-H295R (H295R), a human adrenal cortex cell line which expresses all the key enzymes necessary for steroidogenesis. mRNA/protein for multiple P1 (A(2A) and A(2B)), P2X (
