Purinergic receptor expression in neuronal, bladder smooth muscle and urothelial cells: characterization and inhibition by low molecular weight antagonists [PDF]

, 2009
P2 purinoceptors comprise ionotropic (P2X) and metabotropic (P2Y) receptor families, responsive to nucleotide ligands and diversely distributed on virtually every mammalian cell. Most cells and tissues co-express multiple subtypes of purinoceptor; thus,

Current status and future perspectives of platelet function‐guided precision antiplatelet therapy for patients with cerebral infarction

Neuroprotection, EarlyView.
Antiplatelet agents target the cyclooxygenase‐1 (COX‐1)/thromboxane A2 (TXA2) and adenosine diphosphate (ADP)‐P2Y12 (cytochrome P450 2C19 [CYP2C19]‐metabolized) platelet activation pathways, resulting in either drug resistance or over‐inhibition. The individualized therapeutic window balances ischemic risk (triggered by high on‐treatment platelet ...

New insights into purinergic receptor signaling in neuronal differentiation, neuroprotection, and brain disorders [PDF]

, 2007
Ionotropic P2X and metabotropic P2Y purinergic receptors are expressed in the central nervous system and participate in the synaptic process particularly associated with acetylcholine, GABA, and glutamate neurotransmission. As a result of activation, the

P2X4 purinergic receptor loss alters macrophage homeostasis, cytokine secretion, and phagocytosis in a myeloid-specific P2X4 purinergic receptor knockout mouse

Frontiers in Immunology
IntroductionThe P2X4 purinergic receptor is robustly expressed on tumor-associated macrophages; however, the role of P2X4 purinergic receptors on macrophages is not fully defined.

Sodium Ions Affect GPR17 Conformational States and Functionality

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Sodium is an allosteric modulator of several class‐A GPCR regulating active versus inactive conformation state and may be a critical issue for the optimization of crystallization procedures. Herein, the role of Na+ in the regulation of GPR17 conformational states was studied through MD simulations of GPR17 wild‐type and mutated on two ...

Ontogeny of purinergic receptor-regulated Ca2+ signaling in mouse cortical collecting duct epithelium [PDF]

, 2002
Changes in ATP-induced increase in {[}Ca2+], during collecting duct ontogeny were studied in primary monolayer cultures of mouse ureteric bud (UB) and cortical collecting duct (CCD) cells by Fura-PE3 fluorescence ratio imaging.

Impact of sleep insufficiency and recovery on cancer development

Sleep Research, EarlyView.
Abstract Sleep plays a critical role in overall health, and modern lifestyles, such as shift work and late‐night activities, can significantly impact sleep condition. Insufficient sleep has been associated with various adverse health outcomes, including an increased risk of tumor development.

Metabotropic purinergic receptors in lipid membrane microdomains

, 2013
There is broad evidence that association of transmembrane receptors and signalling molecules with lipid rafts/caveolae provides an enriched environment for protein-protein interactions necessary for signal transduction, and a mechanism for the modulation

Synthesis and Structure-Activity Relationships of Pyridoxal-6-arylazo-5'-phosphate and Phosphonate Derivatives as P2 Receptor Antagonists. [PDF]

, 1998
Novel analogs of the P2 receptor antagonist pyridoxal-5'-phosphate-6-phenylazo-2',4'-disulfonate (PPADS) were synthesized. Modifications were made through functional group substitution on the sulfophenyl ring and at the phosphate moiety through the ...

Adenosine—A Regulator of Human Testicular Peritubular Cells

Andrology, EarlyView.
ABSTRACT Background Extracellular purines, in particular ATP and adenosine, are regulators of physiological and pathophysiological processes throughout the human body. Roles in the human testis are emerging and include actions on peritubular cells, which form the wall of seminiferous tubules.
