Dysregulation of Astrocytic ATP/Adenosine Release in the Hippocampus Cause Cognitive and Affective Disorders: Molecular Mechanisms, Diagnosis, and Therapy. [PDF]
Reactive astrocytes release various molecules, which play a role in maintaining central nervous system (CNS) homeostasis. (1) Gliotransmitters, such as glutamate, γ‐aminobutyric acid (GABA), ATP, and D‐serine, are secreted by vesicular exocytosis. In addition, astrocytes can also release ATP and glutamate through (2) P2X7Rs, (3) connexin‐43 (Cx43 ...

The bumpy road of purinergic inhibitors to clinical application in immune-mediated diseases. [PDF]
Purinergic signaling plays important roles throughout the body in the regulation of organ functions during and following the disruption of homeostasis. This is also reflected by the widespread expression of two families of purinergic receptors (P1 and P2)

The effect of P2 receptor antagonists and ATPase inhibition on sympathetic purinergic neurotransmission in the guinea‐pig isolated vas deferens [PDF]
Intracellular microelectrodes were used to record the transmembrane potential and excitatory junction potentials (e.j.p.s) produced by sympathetic nerve stimulation (1 Hz) in smooth muscle cells of the guinea‐pig isolated vas deferens. The symmetrical 3′‐urea of 8‐(benzamido)naphthalene‐1,3,5‐trisulphonic acid (NF023) produced a concentration ...

Extracellular ATP released by osteoblasts is a key local inhibitor of bone mineralisation [PDF]
Previous studies have shown that exogenous ATP (>1µM) prevents bone formation in vitro by blocking mineralisation of the collagenous matrix. This effect is thought to be mediated via both P2 receptor-dependent pathways and a receptor-independent ...

Identification of atropine-and P2X1 receptor antagonist-reistant, neurogenic contractions of the urinary bladder [PDF]
Acetylcholine and ATP are excitatory cotransmitters in parasympathetic nerves. We used P2X1 receptor antagonists to further characterize the purinergic component of neurotransmission in isolated detrusor muscle of guinea pig urinary bladder.

Purinergic mechanosensory transduction and visceral pain [PDF]
In this review, evidence is presented to support the hypothesis that mechanosensory transduction occurs in tubes and sacs and can initiate visceral pain.

ATP as a presynaptic modulator [PDF]
© 2000 Elsevier Science Inc.There is considerable evidence that ATP acts as a fast transmitter or co-transmitter in autonomic and sensory nerves mostly through activation of ionotropic P2X receptors but also through metabotropic P2Y receptors. By analogy,

Activity-dependent release of Adenosine: a critical re-evaluation of mechanism [PDF]
Adenosine is perhaps the most important and universal modulator in the brain. The current consensus is that it is primarily produced in the extracellular space from the breakdown of previously released ATP.

P2X receptors: epithelial ion channels and regulators of salt and water transport. [PDF]
When the results from electrophysiological studies of renal epithelial cells are combined with data from in vivo tubule microperfusion experiments and immunohistochemical surveys of the nephron, the accumulated evidence suggests that ATP-gated ion ...
