Modulation of tubuloglomerular feedback responsiveness by extracellular ATP

American Journal of Physiology-Renal Physiology, 1993
Experiments were performed in pentobarbital sodium-anesthetized rats to determine the effects of activation of P2 purinoceptors sensitive to ATP on glomerular capillary pressure, as estimated from proximal tubule stop-flow pressure (SFP) measurements, and on the magnitude of maximal tubuloglomerular feedback-mediated reductions in SFP.

Extracellular ATP Stimulates Norepinephrine Uptake in PC12 Cells

Journal of Neurochemistry, 1989
Abstract: This study examined the effects of extracellular ATP on norepinephrine (NE) uptake, using PC12 cells as a model of noradrenergic neurons. Previous experiments with syn‐aptosomes led to the hypothesis that extracellular ATP can regulate NE uptake via an ecto‐protein kinase.

Extracellular ATP regulation of airway secretion

Drug Development Research, 2001
AbstractBoth the superficial epithelium and submucosal glands play a role in airway secretion. Electrophysiological experiments showed that extracellular ATP induced an initial transient increase in Cl– secretion followed by a prolonged inhibition of Na+ absorption in rabbit tracheal epithelium, which lacks submucosal glands.

Sheng li ke xue jin zhan [Progress in physiology], 2003
The change of extracellular adenosine triphosphate (ATP) concentration affects many important physiological functions significantly. As a transmitter, ATP acts on neuro-effector junction directly and/or modulates the release of other neurotransmitters.

Electrophysiological Actions of Extracellular ATP Application

1993
Considerable progress has been made in defining the receptors activated by adenosine, using selective agonists and antagonists. Our understanding of P2 receptor subtypes, where ATP or another phosphorylated nucleoside is thought to be the endogenous ligand is much less precise (1). Highly selective agonists and antagonists are not available. This makes
