International Journal of Molecular Sciences, 2018 Adenosine triphosphate (ATP) has been well established as an important extracellular ligand of autocrine signaling, intercellular communication, and neurotransmission with numerous physiological and pathophysiological roles. In addition to the classical exocytosis, non-vesicular mechanisms of cellular ATP release have been demonstrated in many cell ...

Exocytotic Release of ATP from Cultured Astrocytes [PDF]
Journal of Biological Chemistry, 2007 Astrocytes appear to communicate with each other as well as with neurons via ATP. However, the mechanisms of ATP release are controversial. To explore whether stimuli that increase [Ca(2+)](i) also trigger vesicular ATP release from astrocytes, we labeled ATP-containing vesicles with the fluorescent dye quinacrine, which exhibited a significant co ...

Mechanisms of constitutive and ATP-evoked ATP release in neonatal mouse olfactory epithelium
BMC Neuroscience, 2012 Background ATP is an extracellular signaling molecule with many ascribed functions in sensory systems, including the olfactory epithelium. The mechanism(s) by which ATP is released in the olfactory epithelium has not been investigated.

Quantal Release of ATP in Mouse Cortex [PDF]
The Journal of General Physiology, 2007 Transient currents occur at rest in cortical neurones that reflect the quantal release of transmitters such as glutamate and γ-aminobutyric acid (GABA). We found a bimodal amplitude distribution for spontaneously occurring inward currents recorded from mouse pyramidal neurones in situ, in acutely isolated brain slices superfused with picrotoxin.

Journal of Pharmacological Sciences, 2007 ATP has broad functions as an autocrine/paracrine molecule. The mode of ATP release and its intracellular source, however, are little understood. Here we show that bradykinin via B2-receptor stimulation induces the extracellular release of ATP via the ...

A computational model of a microfluidic device to measure the dynamics of oxygen-dependent ATP release from erythrocytes. [PDF]
PLoS ONE, 2013 Erythrocytes are proposed to be involved in blood flow regulation through both shear- and oxygen-dependent mechanisms for the release of adenosine triphosphate (ATP), a potent vasodilator.

Sphingosine-1-Phosphate Induces ATP Release via Volume-Regulated Anion Channels in Breast Cell Lines
Life, 2021 High interstitial level of ATP and its lysate adenosine in the cancer microenvironment are considered a halo mark of cancer. Adenosine acts as a strong immune suppressor. However, the source of ATP release is unclear.

ATP release through pannexon channels [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2015 Extracellular adenosine triphosphate (ATP) serves as a signal for diverse physiological functions, including spread of calcium waves between astrocytes, control of vascular oxygen supply and control of ciliary beat in the airways. ATP can be released from cells by various mechanisms.
