Anti-platelet therapy: ADP receptor antagonists. [PDF]

open access: yes, 2011
The P2Y(12) receptor on platelets with which ADP interacts has an important role in promoting platelet function and thereby platelet involvement in both haemostasis and thrombosis.

Spatio‐Temporal Diversity of Calcium Activity in Microglia

open access: yesGlia, Volume 74, Issue 3, March 2026.
Ca2+ activity mostly occurs in microglial processes and stays localized. When it spreads, it often shows a directional bias and is constrained by branch points. Activity strongly relies on P2Y12 receptors and is shaped by neuronal activity. ABSTRACT Microglia, the brain's innate immune cells, possess complex, highly motile branched processes. These act

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

open access: yes, 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 (

Metabolic reprogramming of efferocytosis in the tumour microenvironment: From apoptotic‐cell clearance to therapeutic targeting

open access: yesClinical and Translational Medicine, Volume 16, Issue 2, February 2026.
This review systematically deconstructs the pathological efferocytic—metabolic axis in tumours, framing it as a three‐stage, self‐reinforcing cycle: from metabolite‐driven macrophage recruitment, through hijacked surface recognition, to post‐phagocytic metabolic reprogramming that locks in immunosuppression.

GPR99, a new G protein-coupled receptor with homology to a new subgroup of nucleotide receptors

open access: yesBMC Genomics, 2002
Background Based on sequence similarity, the superfamily of G protein-coupled receptors (GPRs) can be subdivided into several subfamilies, the members of which often share similar ligands.

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

open access: yesPLoS 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

Simultaneous quantification of 12 different nucleotides and nucleosides released from renal epithelium and in human urine samples using ion-pair reversed-phase HPLC [PDF]

open access: yes, 2012
Nucleotides and nucleosides are not only involved in cellular metabolism but also act extracellularly via P1 and P2 receptors, to elicit a wide variety of physiological and pathophysiological responses through paracrine and autocrine signalling pathways.

Stromal Cell‐Mast Cell Communication Orchestrates Anti‐Viral Immunity in the Meninges

open access: yesAdvanced Science, Volume 13, Issue 5, 27 January 2026.
This study delineates the spatial distribution and postnatal maturation of meningeal mast cells and uncovers their essential role in antiviral immunity. Using genetic models, mast cells are shown to promote CD8⁺ T cell infiltration and viral clearance via IL‐33 receptor signaling and synergistic activation by IL‐33 and ATP from infected stromal cells ...

Beyond the surface: P2Y receptor downstream pathways, TLR crosstalk and therapeutic implications for infection and autoimmunity

open access: yesPharmacological Research
A successful immune response must effectively obtain pathogen clearance upon infection while preventing excessive collateral tissue damage. It is therefore essential to achieve a nuanced fine regulation of pro- and anti-inflammatory signals to ...

Activation of Extracellular-signal Regulated Kinase (ERK1/2) by Fluid Shear is Ca\u3csup\u3e2+\u3c/sup\u3e- and ATP-dependent in MC3T3-E1 Osteoblasts [PDF]

open access: yes, 2008
To determine the role of Ca2+ signaling in activation of the Mitogen-Activated Protein Kinase (MAPK) pathway, we subjected MC3T3-E1 pre-osteoblastic cells to inhibitors of Ca2+ signaling during application of fluid shear stress (FSS).
