Emerging key roles for P2X receptors in the kidney [PDF]

open access: yes, 2013
P2X ionotropic non-selective cation channels are expressed throughout the kidney and are activated in a paracrine or autocrine manner following the binding of extracellular ATP and related extracellular nucleotides. Whilst there is a wealth of literature

P2X7 receptor antagonism suppresses epileptiform‐like activity in an inflammation‐primed human iPSC‐derived neuron model of drug‐resistant epilepsy

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 2, Page 296-312, January 2026.
Background and Purpose Neuroinflammation is increasingly recognised to contribute to drug‐resistant epilepsy. Activation of ATP‐gated P2X7 receptors has emerged as an important upstream mechanism, and increased P2X7 receptor expression is present in the seizure focus in rodent models and patients. Pharmacological antagonists of P2X7 receptors attenuate

Functional Compartmentation of Endothelial P2Y Receptor Signaling [PDF]

open access: yesCirculation Research, 2002
The presence of multiple receptors for disparate nucleotides on endothelial cells makes it unclear how the endothelium differentiates among these signals. We propose that endothelial P2Y receptors are organized into cholesterol-rich signaling domains, such as caveolae and respond to nucleotide agonists by mobilizing intracellular calcium.

Piezo2 in Mechanosensory Biology: From Physiological Homeostasis to Disease‐Promoting Mechanisms

open access: yesCell Proliferation, Volume 59, Issue 1, January 2026.
Piezo2 channels are essential mechanotransducers regulating touch, proprioception and visceral mechanosensation across physiological systems, emerging as therapeutic targets for pathological mechanical hypersensitivity and neurogenic disorders. ABSTRACT Piezo2, a mechanically activated ion channel, serves as the key molecular transducer for touch ...

Adenosine and acute low oxygen conditions suppress urinary bladder contractility through the activation of adenosine 2B receptors and large‐conductance calcium‐activated potassium channels

open access: yesThe Journal of Physiology, Volume 604, Issue 1, Page 379-394, 1 January 2026.
Abstract figure legend Detrusor smooth muscle surrounding the urinary bladder produces transient pressure events essential for sensing bladder fullness during the filling phase. We investigated the role of adenosine, a ubiquitous signalling molecule, in regulating bladder smooth muscle function.

The favorable kinetics and balance of nebivolol-stimulated nitric oxide and peroxynitrite release in human endothelial cells [PDF]

open access: yes, 2013
Background: Nebivolol is a third-generation beta-blocker used to treat hypertension. The vasodilation properties of nebivolol have been attributed to nitric oxide (NO) release.

Infrared Neural Stimulation Elicits Distinct Molecular Pathways in Astrocytes Based on Laser Pulse Parameters

open access: yesAdvanced Biology, Volume 9, Issue 12, December 2025.
Infrared (IR) light evokes distinct calcium and water transport responses in astrocytes, depending on stimulation duration and protocol. This study uses widefield imaging and pharmacology to reveal differential engagement of astroglial signaling pathways.

Immunogold electron microscopic evidence of in situ formation of homo- and heteromeric purinergic adenosine A1 and P2Y2 receptors in rat brain

open access: yesBMC Research Notes, 2010
Background Purines such as adenosine and ATP are now generally recognized as the regulators of many physiological functions, such as neurotransmission, pain, cardiac function, and immune responses.
