Abstract
The classical small molecule neurotransmitters are essential for cell-cell signaling in the nervous system for regulation of behaviors and physiological functions. Metabolomics approaches are ideal for quantitative analyses of neurotransmitter profiles but have not yet been achieved for the repertoire of 14 classical neurotransmitters. Therefore, this study developed targeted metabolomics analyses by full scan gas chromatography/time-of-flight mass spectrometry (GC-TOF) and hydrophilic interaction chromatography-QTRAP mass spectrometry (HILIC-MS/MS) operated in positive ionization mode for identification and quantitation of 14 neurotransmitters consisting of acetylcholine, adenosine, anandamide, aspartate, dopamine, epinephrine, GABA, glutamate, glycine, histamine, melatonin, norepinephrine, serine, and serotonin. GC-TOF represents a new metabolomics method for neurotransmitter analyses. Sensitive measurements of 11 neurotransmitters were achieved by GC-TOF, and three neurotransmitters were analyzed by LC-MS/MS (acetylcholine, anandamide, and melatonin). The limits of detection (LOD) and limits of quantitation (LOQ) were assessed for linearity for GC-TOF and LC-MS/MS protocols. In neurotransmitter-containing dense core secretory vesicles of adrenal medulla, known as chromaffin granules (CG), metabolomics measured the concentrations of 9 neurotransmitters consisting of the catecholamines dopamine, norepinephrine, and epinephrine, combined with glutamate, serotonin, adenosine, aspartate, glycine, and serine. The CG neurotransmitters were constitutively secreted from sympathoadrenal chromaffin cells in culture. Nicotine- and KCl-stimulated release of the catecholamines and adenosine. Lithium, a drug used for the treatment of bipolar disorder, decreased the constitutive secretion of dopamine and norepinephrine and decreased nicotine-stimulated secretion of epinephrine. Lithium had no effect on other secreted neurotransmitters. Overall, the newly developed GC-TOF with LC-MS/MS metabolomics methods for analyses of 14 neurotransmitters will benefit investigations of neurotransmitter regulation in biological systems and in human disease conditions related to drug treatments.

Abstract
There is widespread involvement of purinergic signalling in endocrine biology. Pituitary cells express P1, P2X and P2Y receptor subtypes to mediate hormone release. Adenosine 5'-triphosphate (ATP) regulates insulin release in the pancreas and is involved in the secretion of thyroid hormones. ATP plays a major role in the synthesis, storage and release of catecholamines from the adrenal gland. In the ovary purinoceptors mediate gonadotrophin-induced progesterone secretion, while in the testes, both Sertoli and Leydig cells express purinoceptors that mediate secretion of oestradiol and testosterone, respectively. ATP released as a cotransmitter with noradrenaline is involved in activities of the pineal gland and in the neuroendocrine control of the thymus. In the hypothalamus, ATP and adenosine stimulate or modulate the release of luteinising hormone-releasing hormone, as well as arginine-vasopressin and oxytocin. Functionally active P2X and P2Y receptors have been identified on human placental syncytiotrophoblast cells and on neuroendocrine cells in the lung, skin, prostate and intestine. Adipocytes have been recognised recently to have endocrine function involving purinoceptors.

Abstract
In nerve-smooth muscle preparations beta-nicotinamide adenine dinucleotide (beta-NAD) has emerged as a novel extracellular substance with putative neurotransmitter and neuromodulator functions. beta-NAD is released, along with noradrenaline and adenosine 5'-triphosphate (ATP), upon firing of action potentials in blood vessels, urinary bladder and large intestine. At present it is unclear whether noradrenaline, ATP and beta-NAD are stored in and released from common populations of synaptic vesicles. The answer is unattainable in complex systems such as nerve-smooth muscle preparations. Adrenal chromaffin cells are thus used here as a single-cell model to examine mechanisms of concomitant neurosecretion. Using high-performance liquid chromatography techniques with electrochemical and fluorescence detection we simultaneously evaluated secretion of dopamine (DA), ATP, adenosine 5'-diphosphate, adenosine 5'-monophosphate, adenosine, beta-NAD and its immediate metabolites ADP-ribose and cyclic ADP-ribose in superfused nerve growth factor-differentiated rat pheochromocytoma PC12 cells. beta-NAD, DA and ATP were released constitutively and upon stimulation with high-K(+) solution or nicotine. Botulinum neurotoxin A tended to increase the spontaneous secretion of all substances and abolished the high-K(+)-evoked release of beta-NAD and DA but not of ATP. Subcellular fractionation by continuous glycerol and sucrose gradients along with immunoblot analysis of the vesicular marker proteins synaptophysin and secretogranin II revealed that beta-NAD, ATP and DA are stored in both small synaptic-like vesicles and large dense-core-like vesicles. However, the three substances appear to have different preferential sites of release upon membrane depolarization including sites associated with SNAP-25 and sites not associated with SNAP-25.

Abstract
This review is focused on purinergic neurotransmission, i.e., ATP released from nerves as a transmitter or cotransmitter to act as an extracellular signaling molecule on both pre- and postjunctional membranes at neuroeffector junctions and synapses, as well as acting as a trophic factor during development and regeneration. Emphasis is placed on the physiology and pathophysiology of ATP, but extracellular roles of its breakdown product, adenosine, are also considered because of their intimate interactions. The early history of the involvement of ATP in autonomic and skeletal neuromuscular transmission and in activities in the central nervous system and ganglia is reviewed. Brief background information is given about the identification of receptor subtypes for purines and pyrimidines and about ATP storage, release, and ectoenzymatic breakdown. Evidence that ATP is a cotransmitter in most, if not all, peripheral and central neurons is presented, as well as full accounts of neurotransmission and neuromodulation in autonomic and sensory ganglia and in the brain and spinal cord. There is coverage of neuron-glia interactions and of purinergic neuroeffector transmission to nonmuscular cells. To establish the primitive and widespread nature of purinergic neurotransmission, both the ontogeny and phylogeny of purinergic signaling are considered. Finally, the pathophysiology of purinergic neurotransmission in both peripheral and central nervous systems is reviewed, and speculations are made about future developments.

Abstract
ATP is an excitatory neurotransmitter in the central and peripheral nervous system. We investigated ATP accumulation in highly purified brain synaptic vesicles (SVs). Based on the amount of ATP accumulated in SVs under the conditions used, ATP is not transported against a concentration gradient but rather appears to have a Delta mu H(+)-independent mechanism. ATP transport was inhibited by DIDS and NEM, but was not affected by Mg(2+) or by pre-incubation with nucleotides. These results suggest a unique transport mechanism that does not involve exchange with other nucleotides or protons, unlike other known neurotransmitter transport systems.

Abstract
We investigated the endogenous control through vesicular contents of voltage-dependent Ca2+ channels (VDCCs) in cultured porcine adrenal chromaffin cells. To examine paracrine regulation of VDCCs, catecholamine release was monitored amperometrically together with patch-clamp recording under culture conditions at different cell densities. A depolarizing pulse evoked Ca(2+)- (ICa) and Ba(2+)-currents (IBa) in Ca(2+)- and Ba(2+)-containing solutions, respectively. In cells cultured at high density, stop-flow of the external solution decreased the I(Ba) concomitant with a sustained increase of amperometric current (Iamp), but not in cells at low density, suggesting the endogenous modulation of VDCCs in a paracine fashion. The degree of the prepulse facilitation was similar regardless of the flow condition. Application of noradrenaline (NA), ATP, methionine-enkephalin (ENK) or protons decreased IBa. The extent of the prepulse facilitation of the endogenous VDCC inhibition was similar to those induced by NA and ATP. GDPbetaS, pertussis toxin (PTX), blockers for alpha-adrenoceptors and P2-purinoceptors significantly reduced the endogenous VDCC inhibition. These results suggest that VDCCs are regulated by vesicular substances in a paracrine fashion, at least by noradrenaline and ATP, through activation of alpha-adrenoceptors and P2-purinoceptors, respectively, in porcine adrenal chromaffin cells.

Abstract
The amounts and time courses of dopamine and ATP released from perfused PC12 cells were examined using a simultaneous on-line recording system. High KCl (60 mM) caused dopamine and ATP release with similar time courses. The relative amount of dopamine to ATP in the effluent was 9.5. In PC12 cells cultured with dexamethasone, reserpine or bafilomycin A1 for 2 days, these drugs did not affect increases of intracellular Ca2+ in response to high KCl. Dexamethasone doubled the amount of dopamine release induced by high KCl without changing the amount of ATP release. High KCl failed to cause dopamine release in reserpine-treated cells but evoked ATP release. Bafilomycin A1 decreased both high KCl-induced dopamine and ATP release. The ratio of released ATP to total adenine nucleotides and adenosine in response to high KCl was not changed by treatment with the drugs. These results suggest that dopamine and ATP are simultaneously released from secretory vesicles of PC12 cells, in which they are stored via different pathways. Similar to dopamine uptake into secretory vesicles, the H+-gradient across the vesicular membrane developed by vacuolar ATPase may play an important role in the vesicular uptake of ATP.
