Purinergic neurotransmission and nucleotide receptors

, 2023
Adenosine 5′-triphosphate (ATP) is a neurotransmitter of postganglionic sympathetic nerves and nonadrenergic, noncholinergic nerves of the enteric nervous system.

Ligand-Independent Spontaneous Activation of Purinergic P2Y₆ Receptor Under Cell Culture Soft Substrate

Cells
G protein-coupled receptors (GPCRs) exist in the conformational equilibrium between inactive state and active state, where the proportion of active state in the absence of a ligand determines the basal activity of GPCRs.

Functional expression and intracellular signaling of UTP-sensitive P2Y receptors in theca-interstitial cells

Reproductive Biology and Endocrinology, 2010
Background Purinergic receptors are expressed in the ovary of different species; their physiological roles remain to be elucidated. UTP-sensitive P2Y receptor activity may regulate cell proliferation.

Cell Type‐Specific Extracellular Vesicles in Mouse Brain: Proteomic Signatures Highlight Astrocytic GlialCAM Network and GPCR Enrichment

Glia, Volume 74, Issue 10, October 2026.
Cell type–specific EVs were isolated from mouse brain and profiled by proteomics. Each EV subtype exhibited proteomic signatures consistent with the specialized functions of its cell of origin. Astrocyte‐derived EVs (ADEVs) were enriched for the GlialCAM/MLC1 network and GPCRs.

Expression of P2 receptors in human B cells and Epstein-Barr virus-transformed lymphoblastoid cell lines

BMC Immunology, 2006
Background Epstein-Barr virus (EBV) infection immortalizes primary B cells in vitro and generates lymphoblastoid cell lines (LCLs), which are used for several purposes in immunological and genetic studies. Purinergic receptors, consisting of P2X and P2Y,

Purinoreceptors and ectonucleotidases control ATP-induced calcium waveforms and calcium-dependent responses in microglia: Roles of P2 receptors and CD39 in ATP-stimulated microglia

Frontiers in Physiology, 2023
Adenosine triphosphate (ATP) and its metabolites drive microglia migration and cytokine production by activating P2X- and P2Y- class purinergic receptors.

G Protein‐Coupled Receptor in High‐Altitude Diseases: Mechanistic Insights and Therapeutic Opportunities

MedComm, Volume 7, Issue 10, October 2026.
High‐altitude hypobaric hypoxia activates multiorgan GPCR signaling networks that regulate ventilatory responses, cerebral endothelial barrier integrity, erythropoiesis and red blood cell metabolism, pulmonary vascular remodeling, and cardiac adaptation. Dysregulated GPCR pathways contribute to acute and chronic high‐altitude diseases, while clinically

Purinergic Receptor P2Y2 Regulates Neurogenesis and Functional Recovery Following Spinal Cord Injury in Zebrafish

The FASEB Journal, Volume 40, Issue 17, 15 September 2026.
Although purinergic P2Y2 receptor can regulate neural stem cell (NSC) proliferation and neurogenesis in mammals, it is downregulated following spinal cord injury (SCI). It was previously unknown whether this receptor regulates these processes in the more‐regenerative zebrafish model, where the contribution of these responses allows near‐complete ...

The Role of Purinergic P2X and P2Y Receptors in Hearing Loss

Journal of Phonetics & Audiology, 2018
Hearing loss is the most common form of sensorineural impairment, affecting 5.3% of the worldwide human population. Whereas 1 in 500 children is born with hearing disorders, sudden or progressive forms of hearing loss can appear at adult age. However, the physiological and molecular mechanisms involved in this pathological process remain unclear ...

Apical membrane P2Y4 purinergic receptor controls K⁺ secretion by strial marginal cell epithelium

Cell Communication and Signaling, 2005
Background It was previously shown that K+ secretion by strial marginal cell epithelium is under the control of G-protein coupled receptors of the P2Y family in the apical membrane.
