P1 and P2 purinergic receptor signal transduction in rat type II pneumocytes

Journal of Applied Physiology, 1989
Extracellular ATP is a potent agonist of surfactant phosphatidylcholine (PC) exocytosis from type II pneumocytes in culture. We studied P1 and P2 receptor signal transduction in type II pneumocytes. The EC50 for ATP on PC exocytosis was 10(-6) M, whereas the EC50 for ADP, AMP, adenosine, and the nonmetabolizable ATP analogue alpha,beta-methylene ATP ...

Purinergic receptors in microglia: Functional modal shifts of microglia mediated by P2 and P1 receptors

Glia, 2012
AbstractMicroglia are sensitive to environmental changes and are immediately transformed into several phenotypes. For such dynamic “modal shifts”, purinergic receptors have central roles. When microglia sense ATP/ADP leaked from injured cells by P2Y12 receptors, they are transformed into a moving phenotype, showing process extension and migration ...

Genistein, an Inhibitor of Protein Tyrosine Kinase, Is Also a Competitive Antagonist for P1-Purinergic (Adenosine) Receptor in FRTL-5 Thyroid Cells

Biochemical and Biophysical Research Communications, 1994
Genistein, a potent inhibitor for protein tyrosine kinase, remarkably inhibited the stimulatory action of N6-(L-2-phenylisopropyl)adenosine (PIA), an A1-adenosine receptor agonist, on thyrotropin (TSH)-induced phospholipase C activation in FRTL-5 thyroid cells.

On the purinergic system in rat duodenum : existence of P1and P2receptors on the smooth muscle

Archives Internationales de Physiologie et de Biochimie, 1990
In rat duodenum, in vitro, in the presence of atropine and guanethidine, ATP administration caused a tetrodotoxin-insensitive relaxation followed by a rebound contraction. A similar response was obtained also after electrical field stimulation (EFS) of non-adrenergic, non-cholinergic (NANC) nerves.

Antihypertensive effects of the Vitis vinifera grape skin (ACH09) extract consumption elicited by functional improvement of P1 (A1) and P2 (P2X1) purinergic receptors in diabetic and hypertensive rats

PharmaNutrition, 2019
Abstract Cross-talk between hypertension and diabetes associated with red wine consumption triggering cardioprotective and antihypertensive effects have been well established; nevertheless, the role of isolated total polyphenols from extracts of Vitis vinifera grape skin (ACH09) and the possible correlation with cardiovascular functionality mediated ...
