GPR80/99, proposed to be the P2Y15 receptor activated by adenosine and AMP, is not a P2Y receptor [PDF]

open access: yesPurinergic Signalling, 2004
The orphan receptor GPR80 (also called GPR99) was recently reported to be the P2Y(15) receptor activated by AMP and adenosine and coupled to increases in cyclic AMP accumulation and intracellular Ca(2+) mobilization (Inbe et al. J Biol Chem 2004; 279: 19790-9). However, the cell line (HEK293) used to carry out those studies endogenously expresses A(2A)

Dual control of vascular tone and remodelling by ATP released from nerves and endothelial cells [PDF]

open access: yes, 2008
Purinergic signalling is important both in short-term control of vascular tone and in longer-term control of cell proliferation, migration and death involved in vascular remodelling.

Transcriptional and translational differences of microglia from male and female brains [PDF]

open access: yes, 2019
Sex differences in brain structure and function are of substantial scientific interest because of sex-related susceptibility to psychiatric and neurological disorders. Neuroinflammation is a common denominator of many of these diseases and thus microglia

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

open access: yesCell 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 ...

The human colon: Evidence for degenerative changes during aging and the physiological consequences

open access: yesNeurogastroenterology &Motility, Volume 37, Issue 8, August 2025.
Reduced nociceptor innervation can explain diminished abdominal pain among the elderly. Degenerative changes occur within the colon wall, especially ascending colon. Mechanisms may include senescence‐like activity and inflammaging. Constipation is more likely to occur during age‐related challenges affecting functions of the bowel that now have reduced ...

Development of selective agonists and antagonists of P2Y receptors [PDF]

open access: yesPurinergic Signalling, 2008
Although elucidation of the medicinal chemistry of agonists and antagonists of the P2Y receptors has lagged behind that of many other members of group A G protein-coupled receptors, detailed qualitative and quantitative structure–activity relationships (SARs) were recently constructed for several of the subtypes.

Resetting intrinsic purinergic modulation of neural activity: an associative mechanism? [PDF]

open access: yes, 2002
The purines, ATP and adenosine, control the rundown and termination of swimming in the Xenopus embryo. This intrinsic purinergic modulation, unavoidably present during every swimming episode, could lead to stereotyped inflexible behavior and consequently

S-Nitrosothiols modulate G protein-coupled receptor signaling in a reversible and highly receptor-specific manner

open access: yesBMC Cell Biology, 2005
Background Recent studies indicate that the G protein-coupled receptor (GPCR) signaling machinery can serve as a direct target of reactive oxygen species, including nitric oxide (NO) and S-nitrosothiols (RSNOs).

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

open access: yesNeurogastroenterology &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 ...
