Purinergic effects on Na,K-ATPase activity differ in rat and human skeletal muscle. [PDF]

PLoS ONE, 2014
P2Y receptor activation may link the effect of purines to increased maximal in vitro activity of the Na,K-ATPase in rat muscle. The hypothesis that a similar mechanism is present in human skeletal muscle was investigated with membranes from rat and human

Use of Human In Vitro Gut Specimens for Translational Neurogastroenterology and Motility in the 21st Century

Neurogastroenterology &Motility, Volume 37, Issue 8, August 2025.
In vitro studies with GI surgical specimens or biopsy are a critical step in translating preclinical studies in animals to humans before testing potential therapeutic interventions in expensive clinical trials. Routine availability of human gut specimens, in combination with technological advances and powerful new in vitro models of the human ENS from ...

Regional differences in store-operated Ca2+ entry in the epithelium of the intact human lens [PDF]

, 2009
An elevated level of Ca2+ is an important factor in cataract, yet precisely how Ca2+ enters the lens is unknown. Lens epithelial cells contain a range of G-protein–coupled receptors and receptor tyrosine kinases that induce increases in intracellular Ca2+

Transcriptomic profiling of dorsal root ganglia in atopic and healthy dogs: A comparative RNA sequencing study with implications in cutaneous itch research

Veterinary Dermatology, Volume 36, Issue 4, Page 401-411, August 2025.
Background – Itch is a common symptom in skin disorders. While the neural pathways of itch transmission from the skin to the brain are well‐understood in rodents, the same pathways in dogs remain unclear. The knowledge gap hinders the development of effective treatments for canine itch‐related disorders.

Potent P2Y(6 )receptor mediated contractions in human cerebral arteries [PDF]

, 2003
BACKGROUND: Extracellular nucleotides play an important role in the regulation of vascular tone and may be involved in cerebral vasospasm after subarachnoidal haemorrhage.

Non‐ionotropic NMDAR signalling activates Panx1 to induce P2X4R‐dependent long‐term depression in the hippocampus

The Journal of Physiology, Volume 603, Issue 15, Page 4367-4381, 1 August 2025.
Abstract figure legend Stimulation of the Shaffer collateral pathway at 3 Hz activates non‐ionotropic NMDA receptors. This subsequently leads to Src kinase mediated phosphorylation of pannexin‐1 (Panx1), which releases ATP from the postsynaptic cell. ATP acts as a ligand for P2X4 receptors to induce long‐term depression (LTD). Abstract In recent years,

Purinergic signalling: past, present and future [PDF]

, 2009
The discovery of non-adrenergic, non-cholinergic neurotransmission in the gut and bladder in the early 1960's is described as well as the identification of adenosine 5'-triphosphate (ATP) as a transmitter in these nerves in the early 1970's.

State-Dependent and -Independent Effects of Dialyzing Excitatory Neuromodulator Receptor Antagonists into the Ventral Respiratory Column [PDF]

, 2017
Unilateral dialysis of the broad-spectrum muscarinic receptor antagonist atropine (50 mM) into the ventral respiratory column [(VRC) including the pre-Bötzinger complex region] of awake goats increased pulmonary ventilation (V̇i) and breathing frequency (

Expression and function of rat urothelial P2Y receptors [PDF]

American Journal of Physiology-Renal Physiology, 2008
The control and regulation of the lower urinary tract are partly mediated by purinergic signaling. This study investigated the distribution and function of P2Y receptors in the rat urinary bladder. Application of P2Y agonists to rat urothelial cells evoked increases in intracellular calcium; the rank order of agonist potency (pEC50 ± SE) was ATP (5.10

Dual role for pannexin 1 at synapses: regulating functional and morphological plasticity

The Journal of Physiology, Volume 603, Issue 15, Page 4237-4253, 1 August 2025.
Abstract figure legend Pannexin 1 (PANX1) regulation of dendritic spines. The postnatal decrease in PANX1 expression could release key spine cytoskeleton‐regulating proteins enabling spine stabilization. Does the physiological decrease in neuronal PANX1 levels across brain development underlie dendritic spine maturation?
