Purinergic receptor expression in neuronal, bladder smooth muscle and urothelial cells: characterization and inhibition by low molecular weight antagonists [PDF]

open access: yes, 2009
P2 purinoceptors comprise ionotropic (P2X) and metabotropic (P2Y) receptor families, responsive to nucleotide ligands and diversely distributed on virtually every mammalian cell. Most cells and tissues co-express multiple subtypes of purinoceptor; thus,

Flow cytometry identifies an early stage of platelet apoptosis produced by agonists of the P2X1 and P2X7 receptors

open access: yesPlatelets, 2022
Platelets express P2X1 receptors and our data also show the expression of P2X7 receptors. We studied the role of both receptors in platelet apoptosis by incubation of PRP with P2X agonists, then centrifuged to remove viable platelets, and analyzed the ...

Ion Channel Dysfunction and Therapeutic Targeting in Salivary Gland Disorders

open access: yesOral Diseases, EarlyView.
ABSTRACT Objective Salivary gland hypofunction and xerostomia represent major clinical complications of radiation therapy, autoimmune disorders such as Sjögren's disease, and inherited epithelial ion transport defects. This review integrates current knowledge on ion channel dysfunction as a central mechanistic driver of salivary gland pathology and ...

Evolution of P2X receptors [PDF]

open access: yesWiley Interdisciplinary Reviews: Membrane Transport and Signaling, 2012
AbstractPurines appear to be the most primitive and widespread chemical messengers in all kingdoms of the Domain Eucarya. There is evidence for purinergic signaling in plants, invertebrates, and lower vertebrates from protozoa to birds. Much is based on pharmacological studies, but important recent papers have utilized the techniques of molecular ...

TMEM16A channel signalling microdomains in the regulation of vascular function

open access: yesThe 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,

Bradykinin Contributes to Sympathetic and Pressor Responses Evoked by Activation of Skeletal Muscle Afferents P2X in Heart Failure

open access: yesCellular 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).

Anatomical and functional mapping of vagal nociceptive sensory nerve subsets innervating the mouse lower airways by intersectional genetics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We used an intersectional approach with recombinase‐expressing mice and adeno‐associated virus to map and modulate distinct nociceptive afferents in the vagal ganglia. TRPV1+P2X2+ neurons resided in the nodose ganglion (N), innervated the lungs (many projected into the alveoli) but not the trachea, and projected to the nucleus ...

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

open access: yesThe 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.

Slow Neuromodulation Mediated by ATP P2X Receptors [PDF]

open access: yes, 2014
ATP-gated P2X receptors are widely expressed in the nervous system, but their physiological roles are not fully understood. New insights from Pougnet et al.
