Abstract
Ca2+ is an essential trigger for most forms of synaptic plasticity. Ca2+ signaling occurs not only by Ca2+ entry via plasma membrane channels but also via Ca2+ signals generated by intracellular organelles. These organelles, by dynamically regulating the spatial and temporal extent of Ca2+ elevations within neurons, play a pivotal role in determining the downstream consequences of neural signaling on synaptic function. Here, we review the role of three major intracellular stores: the endoplasmic reticulum, mitochondria, and acidic Ca2+ stores, such as lysosomes, in neuronal Ca2+ signaling and plasticity. We provide a comprehensive account of how Ca2+ release from these stores regulates short- and long-term plasticity at the pre- and postsynaptic terminals of central synapses.

Abstract
Since the discovery of the Ca(2+) mobilizing effects of the pyridine nucleotide metabolite, nicotinic acid adenine dinucleotide phosphate (NAADP), this molecule has been demonstrated to function as a Ca(2+) mobilizing intracellular messenger in a wide range of cell types. In this review, I will briefly summarize the distinct principles behind NAADP-mediated Ca(2+) signalling before going on to outline the role of this messenger in the physiology of specific cell types. Central to the discussion here is the finding that NAADP principally mobilizes Ca(2+) from acidic organelles such as lysosomes and it is this property that allows NAADP to play a unique role in intracellular Ca(2+) signalling. Lysosomes and related organelles are small Ca(2+) stores but importantly may also initiate a two-way dialogue with other Ca(2+) storage organelles to amplify Ca(2+) release, and may be strategically localized to influence localized Ca(2+) signalling microdomains. The study of NAADP signalling has created a new and fruitful focus on the lysosome and endolysosomal system as major players in calcium signalling and pathophysiology.

Abstract
Nicotinic acid adenine dinucleotide phosphate (NAADP) is an endogenous Ca2+ mobilizing nucleotide presented in various species. NAADP mobilizes Ca2+ from acidic organelles through two pore channel 2 (TPC2) in many cell types and it has been previously shown that NAADP can potently induce neuronal differentiation in PC12 cells. Here we examined the role of TPC2 signaling in the neural differentiation of mouse embryonic stem (ES) cells. We found that the expression of TPC2 was markedly decreased during the initial ES cell entry into neural progenitors, and the levels of TPC2 gradually rebounded during the late stages of neurogenesis. Correspondingly, TPC2 knockdown accelerated mouse ES cell differentiation into neural progenitors but inhibited these neural progenitors from committing to neurons. Overexpression of TPC2, on the other hand, inhibited mouse ES cell from entering the early neural lineage. Interestingly, TPC2 knockdown had no effect on the differentiation of astrocytes and oligodendrocytes of mouse ES cells. Taken together, our data indicate that TPC2 signaling plays a temporal and differential role in modulating the neural lineage entry of mouse ES cells, in that TPC2 signaling inhibits ES cell entry to early neural progenitors, but is required for late neuronal differentiation.

Abstract
The intracellular free calcium concentration subserves complex signaling roles in brain. Calcium cations (Ca(2+)) regulate neuronal plasticity underlying learning and memory and neuronal survival. Homo- and heterocellular control of Ca(2+) homeostasis supports brain physiology maintaining neural integrity. Ca(2+) fluxes across the plasma membrane and between intracellular organelles and compartments integrate diverse cellular functions. A vast array of checkpoints controls Ca(2+), like G protein-coupled receptors, ion channels, Ca(2+) binding proteins, transcriptional networks, and ion exchangers, in both the plasma membrane and the membranes of mitochondria and endoplasmic reticulum. Interactions between Ca(2+) and reactive oxygen species signaling coordinate signaling, which can be either beneficial or detrimental. In neurodegenerative disorders, cellular Ca(2+)-regulating systems are compromised. Oxidative stress, perturbed energy metabolism, and alterations of disease-related proteins result in Ca(2+)-dependent synaptic dysfunction, impaired plasticity, and neuronal demise. We review Ca(2+) control processes relevant for physiological and pathophysiological conditions in brain tissue. Dysregulation of Ca(2+) is decisive for brain cell death and degeneration after ischemic stroke, long-term neurodegeneration in Alzheimer's disease, Parkinson's disease, Huntington's disease, inflammatory processes, such as in multiple sclerosis, epileptic sclerosis, and leucodystrophies. Understanding the underlying molecular processes is of critical importance for the development of novel therapeutic strategies to prevent neurodegeneration and confer neuroprotection.

NAADP-mediated channel 'chatter' in neurons of the rat medulla oblongata. Biochem J 2009; 419:91-7, 2 p following 97.

Abstract
NAADP (nicotinic acid-adenine dinucleotide phosphate) is a potent Ca(2+)-mobilizing messenger that stimulates Ca(2+) release in a variety of cells. NAADP-sensitive Ca(2+) channels are thought to reside on acidic Ca(2+) stores and to be functionally coupled to IP(3) (inositol 1,4,5-trisphosphate) and/or ryanodine receptors located on the endoplasmic reticulum. Whether NAADP-sensitive Ca(2+) channels 'chatter' to other channels, however, is not clear. In the present study, we have used a cell-permeant NAADP analogue to probe NAADP-mediated responses in rat medulla oblongata neurons. NAADP-AM (NAADP-acetoxymethyl ester) evoked global cytosolic Ca(2+) signals in isolated neurons that were reduced in amplitude by removal of external Ca(2+), abolished by disruption of acidic compartments and substantially inhibited by blockade of ryanodine receptors. In rat medullary slices, NAADP-AM depolarized neurons from the nucleus ambiguus in the presence of intracellular EGTA, but not of the faster Ca(2+) chelator BAPTA [1,2-bis-(o-aminophenoxy)ethane-N,N,N',N'-tetra-acetic acid]. Depolarization was also dependent upon extracellular Ca(2+), acidic stores and ryanodine receptors. In voltage-clamp mode, NAADP-AM induced an inward current with a reversal potential of approx. 0 mV. The results of the present study reveal the presence of acidic NAADP-sensitive Ca(2+) stores in medulla neurons, the mobilization of which results not only in global Ca(2+) signals but also in local signals that activate non-selective cation channels on the cell surface resulting in depolarization. Thus NAADP is capable of co-ordinating channels both within the cell interior and at the cell membrane representing a novel mechanism for excitation of central neurons.

Abstract
Many physiological processes are controlled by a great diversity of Ca2+ signals that depend on Ca2+ entry into the cell and/or Ca2+ release from internal Ca2+ stores. Ca2+ mobilization from intracellular stores is gated by a family of messengers including inositol-1,4,5-trisphosphate (InsP3), cyclic ADP-ribose (cADPR), and nicotinic acid adenine dinucleotide phosphate (NAADP). There is increasing evidence for a novel intracellular Ca2+ release channel that may be targeted by NAADP and that displays properties distinctly different from the well-characterized InsP3 and ryanodine receptors. These channels appear to localize on a wider range of intracellular organelles, including the acidic Ca2+ stores. Activation of the NAADP-sensitive Ca2+ channels evokes complex changes in cytoplasmic Ca2+ levels by means of channel chatter with other intracellular Ca2+ channels. The recent demonstration of changes in intracellular NAADP levels in response to physiologically relevant extracellular stimuli highlights the significance of NAADP as an important regulator of intracellular Ca2+ signaling.

Abstract
Nicotinic acid adenine dinucleotide phosphate (NAADP) is a potent intracellular Ca2+ signalling second messenger, but the mechanism of NAADP-induced Ca2+ release is still poorly understood. The present study tested the hypothesis that NAADP induces Ca2+ release from the lysosomal store via a TRP-ML1 (transient receptor potential-mucolipin 1)-mediated Ca2+ release channel in coronary arterial myocytes (CAMs). RT-PCR and Western blot analyses demonstrated that TRP-ML1 was present in CAMs, and fluorescence resonance energy transfer (FRET) detection revealed that the TRP-ML1 was closely associated with some lysosomal proteins in these CAMs. ET-1, a well-known NAADP stimulator, was found to induce a local Ca2+ burst from lysosomes followed by a global Ca2+ release. This lysosome-associated Ca2+ release was significantly inhibited in the TRP-ML1 siRNA pre-treated CAMs by 46.8 ± 12.6% in the local Ca2+ burst and 73.3 ± 14.9% in the global Ca2+ wave. In the reconstituted lysosomal channels from CAMs, NAADP activated Ca2+ release channels at concentrations of 1–1000 nM, but neither activators (1 μM IP3, 5 μM Rya) nor blockers (100 μM 2-APB, 50 μM Rya) of sarcoplasmic reticulum (SR) Ca2+ release channels had effect on the channel activity. Moreover, TRP-ML1 gene silencing reduced this NAADP-sensitive Ca2+ release channel activity in lysosomes by 71.5 ± 18.5%. Immunoprecipitation or blockade of TRP-ML1 by anti-TRP-ML1 antibodies almost abolished NAADP-induced activation of lysosomal Ca2+ channels (to 14.0 ± 4.4% of control). These results for the first time provide direct evidence that an NAADP-sensitive Ca2+ release channel is characteristic of TRP-ML1 channels.

Abstract
In neurons, voltage-gated Ca(2+) channels and nuclear Ca(2+) signaling play important roles, such as in the regulation of gene expression. However, the link between electrical activity and biochemical cascade activation involved in the generation of the nuclear Ca(2+) signaling is poorly understood. Here we show that depolarization of Aplysia neurons induces the translocation of ADP-ribosyl cyclase, a Ca(2+) messenger synthesizing enzyme, from the cytosol into the nucleus. The translocation is dependent on Ca(2+) influx mainly through the voltage-dependent L-type Ca(2+) channels. We report also that specific nucleoplasmic Ca(2+) signals can be induced by three different calcium messengers, cyclic ADP-ribose, nicotinic acid adenine dinucleotide phosphate (NAADP), both produced by the ADP-ribosyl cyclase, and inositol 1,4,5-trisphosphate (IP(3)). Moreover, our pharmacological data show that NAADP acts on its own receptor, which cooperates with the IP(3) and the ryanodine receptors to generate nucleoplasmic Ca(2+) oscillations. We propose a new model where voltage-dependent L-type Ca(2+) channel-induced nuclear translocation of the cytosolic cyclase is a crucial step in the fine tuning of nuclear Ca(2+) signals in neurons.

Abstract
Nuclear calcium regulation is essential for controlling nuclear processes such as gene expression. Recent studies, mostly performed on immortalized or transformed cell lines, reported the presence of a nucleoplasmic reticulum (NR). It has been suggested that NR acts as a storage organelle having an important role in nuclear Ca2+ signalling. However, whether NR is present and necessary in primary neurons for generation of nuclear Ca2+ signalling has never been investigated. Here, we show, by confocal microscopy and by electronic microscopy, that nuclei in intact neurons or isolated nuclei are not endowed with NR. Finally, our experiments performed on isolated nuclei from Aplysia giant neurons show that the nuclear envelope acts as a functional Ca2+ store which can be mobilized by the second messenger cyclic ADPribose to elicit a nucleoplasmic Ca2+ elevation. Our study provides evidence that nuclear Ca2+ signals can be independent of the presence of NR in neurons.

Abstract
It remains unclear how different intracellular stores could interact and be recruited by Ca(2+)-releasing messengers to generate agonist-specific Ca(2+) signatures. In addition, refilling of acidic stores such as lysosomes and secretory granules occurs through endocytosis, but this has never been investigated with regard to specific Ca(2+) signatures. In pancreatic acinar cells, acetylcholine (ACh), cholecystokinin (CCK), and the messengers cyclic ADP-ribose (cADPR), nicotinic acid adenine dinucleotide phosphate (NAADP), and inositol 1,4,5-trisphosphate (IP(3)) evoke repetitive local Ca(2+) spikes in the apical pole. Our work reveals that local Ca(2+) spikes evoked by different agonists all require interaction of acid Ca(2+) stores and the endoplasmic reticulum (ER), but in different proportions. CCK and ACh recruit Ca(2+) from lysosomes and from zymogen granules through different mechanisms; CCK uses NAADP and cADPR, respectively, and ACh uses Ca(2+) and IP(3), respectively. Here, we provide pharmacological evidence demonstrating that endocytosis is crucial for the generation of repetitive local Ca(2+) spikes evoked by the agonists and by NAADP and IP(3). We find that cADPR-evoked repetitive local Ca(2+) spikes are particularly dependent on the ER. We propose that multiple Ca(2+)-releasing messengers determine specific agonist-elicited Ca(2+) signatures by controlling the balance among different acidic Ca(2+) stores, endocytosis, and the ER.
