Uridine adenosine tetraphosphate (Up4A) as a novel coronary vasodilator in health and disease: Role of purinergic P1 and P2 receptors

open access: yesThe FASEB Journal, 2012
Up4A is a potent endothelium‐derived contracting factor that contains purine and pyrimidine moieties and activates purinergic P2X and P2Y receptors. Up4A has recently been found to also have vasodilator effects. Here, we evaluated Up4A in isolated coronary small arteries from normal (N) swine and swine after myocardial infarction ...

Functions of Purinergic Receptors [PDF]

open access: yesReceptors P1 and P2 as Targets for Drug Therapy in Humans, 2019
Purinergic receptors, also known as purinoceptors, are a family of plasma membrane molecules found in many mammalian tissues. Purinergic receptors are transmembrane receptors consisting of two main categories.

The P2X7 Receptor and Its Relation to Neglected Tropical Diseases: Focusing on Chagas Disease. [PDF]

open access: yesJ Trop Med
Chagas disease, caused by Trypanosoma cruzi, is a neglected tropical disease (NTD) that can lead to severe cardiac complications, including chronic Chagas cardiomyopathy. While NTDs are caused by a variety of pathogens—such as protozoa, bacteria, viruses, and helminths, Chagas disease remains underexplored, particularly regarding host immune responses.

Purinergic enzymes on extracellular vesicles: immune modulation on the go

open access: yesFrontiers in Immunology
An increase in the extracellular concentration of ATP as a consequence of cellular stress or cell death results in the activation of immune cells. To prevent inflammation, extracellular ATP is rapidly metabolized to adenosine, which deploys an anti ...

Adenosine receptors as emerging therapeutic targets for diabetic kidney disease [PDF]

open access: yesKidney Research and Clinical Practice, 2022
Diabetic kidney disease (DKD) is now a pandemic worldwide, and novel therapeutic options are urgently required. Adenosine, an adenosine triphosphate metabolite, plays a role in kidney homeostasis through interacting with four types of adenosine receptors

Expression profiles of purinergic P1 and P2 receptors in cultured bovine aortic endothelial cells, bovine aortic smooth muscle cells, and human vascular endothelial EA.hy926 cells

open access: yesThe Journal of Toxicological Sciences
Purinergic signaling plays an important role in vascular biology by vascular tone, inflammation, and remodeling through extracellular nucleotides that activate the P1 and P2 receptors.

The adenosinergic machinery in cancer: In-tandem insights from basic mechanisms to therapy

open access: yesFrontiers in Immunology, 2023
Extracellular adenosine (eADO) signaling has emerged as an increasingly important regulator of immune responses, including tumor immunity. eADO is mainly produced from extracellular ATP (eATP) hydrolysis.

Role of P1 purinergic receptors in myocardial ischemia sensory transduction [PDF]

open access: yesCardiovascular Research, 2002
To characterize the role that cardiac sensory P(1) purinergic (adenosine A(1) or A(2)) receptors play in transducing myocardial ischemia.Porcine nodose ganglion cardiac sensory neuron adenosine A(1) or A(2) receptor function was studied in situ during control states as well as in the presence of the peptides bradykinin and substance P or focal ...
