TY - JOUR. T1 - Decreased vesicular monoamine transporter 2 (VMAT2) and dopamine transporter (DAT) function in knockout mice affects aging of dopaminergic systems. AU - Hall, F S. AU - Itokawa, K. AU - Schmitt, A. AU - Moessner, R. AU - Sora, I. AU - Lesch, K P. AU - Uhl, G R. N1 - Published by Elsevier Ltd.. PY - 2014/1. Y1 - 2014/1. N2 - Dopamine (DA) is accumulated and compartmentalized by the dopamine transporter (DAT; SLC3A6) and the vesicular monoamine transporter 2 (VMAT2; SLC18A2). These transporters work at the plasma and vesicular membranes of dopaminergic neurons, respectively, and thus regulate levels of DA in neuronal compartments that include the extravesicular cytoplasmic compartment. DA in this compartment has been hypothesized to contribute to oxidative damage that can reduce the function of dopaminergic neurons in aging brains and may contribute to reductions in dopaminergic neurochemical markers, locomotor behavior and responses to dopaminergic drugs that are found in aged ...

The vesicular monoamine transporter (VMAT) is a transport protein integrated into the membrane of synaptic vesicles of presynaptic neurons. It acts to transport monoamine neurotransmitters - such as dopamine, serotonin, norepinephrine, epinephrine, and histamine - into the vesicles, which release the neurotransmitters into synapses as chemical messages to postsynaptic neurons. VMATs utilize a proton gradient generated by V-ATPases in vesicle membranes to power monoamine import. Pharmaceutical drugs that target VMATs have possible applications for many conditions, leading to a plethora of biological research. These applications include hypertension, drug addiction, psychiatric disorders, Parkinsons disease, and other neurological disorders. Many drugs that target VMAT act as inhibitors and alter the kinetics of the protein. Much research regarding the effects of altered VMATs on biological systems is still ongoing. The two VMAT isoforms are: VMAT1 VMAT2 Monoamines transported by VMATs are mainly ...

Wilson, J.M.; Carroll, M.E.; Kish, S.J., 1995: The vesicular monoamine transporter, in contrast to the dopamine transporter, is not regulated following chronic cocaine self-administration

In this study we investigated the regulation of the activity of the vesicular monoamine transporters VMAT1 and VMAT2 by heterotrimeric G-proteins. In the human neuroendocrine cell line BON both transporters are expressed. They colocalize in these cells with the a-subunit of the heterotrimeric G-protein Go2 predominantely on Large Dense Core Vesicles (LDCVs). The activity of both VMAT1 and VMAT2 is regulated by Gao2. G-protein activation results in a down-regulation of vesicular monoamine uptake. VMAT2 appears to be more sensitive towards the observed G-protein regulation than VMAT1. Serotonergic raphe neurons in primary culture express VMAT2 as the neuronal form of the transporter. In these neurons VMAT2 predominantely localizes to Small Synaptic Vesicles (SSVs). Here, VMAT2 colocalizes with Gao2 on SSVs. In these neurons Gao2-dependent down-regulation of VMAT2 activity was observed, too. Immunoelectron microscopic analysis confirmed a localization of VMAT2 and Gao2 on SSVs from serotonergic ...

The vesicular monoamine transporter 1 (VMAT1) is essential for storage of monoamines, such as epinephrine and serotonin, in secretory vesicles of neuroendocrine cells. Recently the VMAT1 protein was detected in human and mouse brain, and mutations of the VMAT1 gene at single DNA nucleotides (single nucleotide polymorphisms or SNPs) were associated with schizophrenia. In this study, Chinese hamster ovarian cells were stably transfected with either human VMAT1 DNA (GenBank: #NM_003053.1 or DNA with the Thr4Pro SNP, which results in a threonine to proline change in amino acid number 4 of the VMAT1 protein. Western blot analysis revealed that cells with the SNP produced immunoreactive human VMAT1 proteins of altered molecular size, suggesting that SNP Thr4Pro modifies either folding or processing of the VMAT1 protein. This finding is the first evidence for biochemical consequences of a mutation in the human VMAT1 gene.

Positron emission tomography (PET) visualization of brain components in vivo is a rapidly growing field. Molecular imaging with PET is also increasingly used in drug development, especially for the determination of drug receptor interaction for CNS-active drugs. This gives the opportunity to relate clinical efficacy to per cent receptor occupancy of a drug on a certain targeted receptor and to relate drug pharmacokinetics in plasma to interaction with target protein. In the present review we will focus on the study of transporters, such as the monoamine transporters, the P-glycoprotein (Pgp) transporter, the vesicular monoamine transporter type 2, and the glucose transporter using PET radioligands. Neurotransmitter transporters are presynaptically located and in vivo imaging using PET can therefore be used for the determination of the density of afferent neurons. Several promising PET ligands for the noradrenaline transporter (NET) have been labeled and evaluated in vivo including in man, but a ...

In general, DA, after its synthesis, is taken up and stored in specialized subcellular organelles, the storage granules, to ensure its regulated release via exocytosis. Most information about the granular transport mechanism(s) and storage mechanism(s) of DA (and monoamines in general) has been obtained by using chromaffin granules isolated from adrenal medullary cells or PC12 cells as experimental substrate (Roda et al., 1980). Thus, it is presently known that the DAergic granular transport system consists of at least two components: (1) a so-called vesicular monoamine transporter (VMAT), structurally distinct from the plasma membrane DA transporter, and (2) a vacuolar-type ATP-driven H+ pump, which provides the electrochemical gradient on which the transporter depends for its function (Johnson, 1988; Schuldiner, 1994). Drugs such as reserpine and tetrabenazine deplete intracellular DA stores by selectively interfering with transmitter uptake via the VMAT. In the present set of experiments, we ...

Aromatic l-amino acid decarboxylase (AADC) converts l-5-hydroxytryptophan to 5HT; it is widely distributed and has broad substrate specificity. The synthesized product, 5HT, is accumulated in secretory granules by a vesicular monoamine transporter (VMAT2); vesicular 5HT is released by exocytosis from serotonergic neurons. In the nervous system, the action of released 5HT is terminated via neuronal uptake by a specific 5HT transporter (SERT), localized in the membrane of serotonergic axon terminals and in the membrane of platelets. This uptake system is the means by which platelets acquire 5HT, since they lack the enzymes required for 5HT synthesis. The amine transporters are distinct from VMAT2, which concentrates amines in intracellular storage vesicles and is a nonspecific amine carrier, whereas the 5HT transporter is specific. ...

The effects of lobeline on the acute and long-term effects of a high-dose METH regimen were examined. Preadministration of lobeline did not alter METH-induced dopamine release in vivo but attenuated the hyperthermia produced by METH, the rapid decrease in VMAT immunoreactivity, and the long-term depletions in striatal dopamine and 5HT content. Administration of lobeline at time points after METH when hyperthermia had dissipated also protected against METH-induced decreases in VMAT immunoreactivity and the long-term depletions of dopamine and 5HT content.. Systemic administration of lobeline did not affect basal or METH-induced increases in extracellular dopamine (Fig. 1). These results appear to be in contrast to previous findings indicating that intrastriatal infusion of lobeline increased dopamine release (Lecca et al., 2000), whereas systemic lobeline administration attenuated the locomotor hyperactivity after METH and decreased METH self-administration (Harrod et al., 2001; Miller et al., ...

Antisera. An affinity-purified rabbit polyclonal antiserum directed against a synthetic peptide [(C)SYPIGDDEESESD] at the C terminus of VMAT2 was raised in rabbits as described previously (Peter et al., 1995). The specificity of this antiserum has been demonstrated by Western blot analysis and immunocytochemistry (Nirenberg et al., 1995; Peter et al., 1995). A well characterized mouse monoclonal antiserum directed against TH was purchased from Incstar (Stillwater, MN).. Tissue preparation. The methods for tissue preparation and immunolabeling were based on those of Leranth and Pickel (1989). Four adult male Sprague-Dawley rats (250-400 gm; Taconic Farms, Germantown, NY) were anesthetized with sodium pentobarbital (50 mg/kg, i.p.) and perfused through the ascending aorta with 40 ml of heparin (1000 U/ml heparin in 0.15 m NaCl) and 50 ml of 3.75% acrolein, followed by 200 ml of 2% paraformaldehyde in 0.1 m phosphate buffer (PB), pH 7.4. The brains were removed and postfixed for 30 min in 2% ...

The idea of targeting cancer therapeutics towards specific mutations or abnormalities in tumor cells which are not found in normal tissues has the potential advantages of high selectivity for the tumor and correspondingly low secondary toxicities. pathways of Ras such as growth factor receptors or PI3-Kinase and Raf/MAP kinases. We previously reported that aberrant activation of Ras signaling sensitizes cells to apoptosis when the activity of the PKCδ isozyme is usually suppressed and that PKCδ suppression is not harmful to cells with normal levels of p21Ras signaling. We demonstrate here that inhibition of PKCδ by a number of unbiased means including hereditary systems (shRNA) or little molecule inhibitors can effectively and selectively repress the development of individual neuroendocrine cell lines produced from bronchopulmonary foregut or hindgut tumors. PKCδ inhibition in these tumors efficiently induced apoptosis also. Contact with small-molecule Troxacitabine inhibitors Rabbit ...

The Conus genus includes around 500 species of marine mollusks using a peculiar production of venomous peptides referred to as conotoxins (CTX). S1) living generally in the tropical marine areas. About 700 species of Cone snails express hundreds of peptide toxins collectively known as conotoxins (CTX) aimed to self-defense, competition and predation of other marine species by means of stingCstructures that were reported to be fatal for human since from 300 years ago. CTX, however, do not exert only venomous activity but have a lot of pharmacological properties with specific bioactivity in the treatment of neurological disorders and the associated pain belief [1,2,3]. The presence of disulfide bonds is the important characteristic for natural function of CTX that enable to separate CTX into two primary types, the disulfide-rich peptides and no-disulfide-rich types; the foremost is generally composed of no more than 30 proteins and the next contains as much as 80 proteins. CTX are grouped into ...

Parkinsons Disease (PD) is a complex, chronic, progressive, and debilitating neurodegenerative disorder. Neither a cure nor effective long-term therapy exist and the lack of knowledge of the molecular mechanisms responsible for PD development is a major impediment to therapeutic advances. The protein alphaSynuclein is a central component in PD pathogenesis yet its cellular targets and mechanism of toxicity remains unknown. Mitochondrial dysfunction is also a common theme in PD patients and this review explores the strong possibility that alphaSynuclein and mitochondrial dysfunction have an inter-relationship responsible for underlying the disease pathology. Amplifying cycles of mitochondrial dysfunction and alphaSynuclein toxicity can be envisaged, with either being the disease-initiating factor yet acting together during disease progression. Multiple potential mechanisms exist in which mitochondrial dysfunction and alphaSynuclein could interact to exacerbate their neurodegenerative properties.

The dopamine (DAT), serotonin (SERT), and norepinephrine (NET) transporters, which are collectively referred to as monoamine transporters (MATs), play significant roles in regulating the neuronal response to these neurotransmitters

The aim of the present study was to analyze and to compare quantitative aspects of inward and outward transport of substrates by the human SERT to obtain more insight into the mechanisms of carrier-mediated release. As in our previous study on the rat (Sitte et al., 2000) and human SERT (Scholze et al., 2000), we used the natural substrate 5-HT, and MPP+, a commonly used substrate for all monoamine transporters (Wall et al., 1995). 5-HT and MPP+ differ in theirK m value for the hSERT by a factor of about 25 (0.6 versus 17 μM, respectively) and in their lipophilicity. These differences are the cause of some typical findings, which have been partly discussed previously (Scholze et al., 2000; Sitte et al., 2000) and will be reviewed here because of their relevance for the present findings. Because the cells used in the present experiments do not possess a vesicular storage mechanism, accumulated 5-HT will leave the cytoplasm by diffusion, but is partly subject to reuptake because of its high ...

Mast cells donate to allergy through IgE-dependent activation the high-affinity IgE receptor FcεRI. receptor gain-of-function human mast cell line HMC-1. Unlike MS4A2 MS4A2trunc did not traffic to the cytoplasmic membrane but instead was associated with the nuclear membrane. Overexpression of MS4A2trunc induced human lung mast cell death and profoundly inhibited HMC-1 cell proliferation by inducing G2-phase cell cycle arrest and apoptosis. Thus we have identified a novel splice variant of MS4A2 that might be important in the regulation of human mast cell proliferation and survival. This finding demonstrates that the MS4A2 gene has multiple roles extending beyond the rules of acute sensitive reactions. By understanding the systems regulating its function it could be feasible to induce its manifestation in mast cells cells had been then transformed using the MS4A2 clones and plated from agar plates including 100 μg/ml ampicillin with 100 μl of IPTG and 20 μl of X-galactose added.

Recent publications, however, reported unexpected toxicity after utilizing viral-mediated shRNA knockdown in vivo. Thus, it is currently unclear whether shRNA-mediated knockdown strategy can be used as a safe and efficient tool for gene silencing. In this study, we have generated rAAV vectors expressing shRNAs targeting the rat tyrosine hydroxylase (TH) mRNA (shTH) for testing the efficacy of in vivo TH knockdown in the nigral dopaminergic neurons. At high titers, not only the shTH vectors but also the scrambled and green fluorescence protein (GFP)-only controls caused cell death. In a dose-response study, we identified a dose window leading to >60% decrease in TH(+) neurons without any change in vesicular monoamine transporter-2 (VMAT2) expression. Moreover, using the safe and efficient dose, we ...

The vesicular monoamine transporter acts to accumulate cytosolic monoamines into vesicles, using the proton gradient maintained across the vesicular membrane. Its proper function is essential to the correct activity of the monoaminergic systems that have been implicated in several human neuropsychiatric disorders. The transporter is a site of action of important drugs, including reserpine and tetrabenazine (Peter et al., 1993 [PubMed 7905859]). See also SLC18A2 (MIM 193001).[supplied by OMIM, Mar 2008 ...

DESCRIPTION (provided by applicant): The goal of this CUTTING EDGE BASIC RESEARCH AWARD (CEBRA) application, submitted in response to PAR-09-222, is to determine the extent to which the G protein-coupled trace amine-associated receptor 1 (TAAR1) contributes to intravenous (i.v.) methamphetamine (METH) self-administration (SA). METH consumption is declining nation-wide yet significant use persists in specific demographics of the United States and around the world in spite of the overwhelmingly negative personal, familial, societal, and legal consequences associated with its use and abuse. For more than 50 years psychostimulant research has attempted to identify the biological substrates mediating METHs abuse potential. In spite of clarifying some of the biological mechanisms underlying METHs actions (e.g. interference with monoamine oxidase activity as well as dopamine, norepinephrine and vesicular monoamine transporter functions) there is still no widely accepted pharmacologic approach to ...

Introduction: The most abundant neuroendocrine (NE) cell population of the human oxyntic mucosa is the enterochromaffin-like (ECL) cells, followed by ghrelin, somatostatin and serotonin cells, respectively. All types of ECL cell carcinoids (ECL-CCs) contain serotonin cells but in a varying frequency. Hitherto, only foci of ECL and ghrelin cell hyperplasia have been described in the peritumorous mucosa of types I and II ECL-CCs. It is established that hypergastrinaemia can cause ECL cell hyperplasia but it does not affect serotonin cells. The vesicular monoamine transporter 2 (VMAT 2) is used as an immunohistochemical marker for ECL cells ...

MATs (monoamine transporters) are protein structures that function as integral plasma-membrane transporters to regulate concentrations of extracellular monoamine neurotransmitters. Three major classes of MATs (SERT, DAT, NET) are responsible for the reuptake of their associated amine neurotransmitters (serotonin, dopamine, norepinephrine). MATs are located just outside the synaptic cleft (peri-synaptically), transporting monoamine transmitter overflow from the synaptic cleft back to the cytoplasm of the pre-synaptic neuron. MAT regulation generally occurs throughphosphorylation and posttranslational modification. Due to their significance in neuronal signaling, MATs are commonly associated with drugs used to treat mental disorders as well as recreational drugs.

The God gene hypothesis proposes that human spirituality is influenced by heredity and that a specific gene, called vesicular monoamine transporter 2 (VMAT2), predisposes humans towards spiritual or mystic experiences. The idea has been proposed by geneticist Dean Hamer in the 2004 book called The God Gene: How Faith is Hardwired into our Genes. The God gene hypothesis is based on a combination of behavioral genetic, neurobiological and psychological studies. The major arguments of the hypothesis are: (1) spirituality can be quantified by psychometric measurements; (2) the underlying tendency to spirituality is partially heritable; (3) part of this heritability can be attributed to the gene VMAT2; (4) this gene acts by altering monoamine levels; and (5) spirituality provides an evolutionary advantage by providing individuals with an innate sense of optimism. According to the God Gene hypothesis, spirituality has a genetic component, of which (VMAT2) comprises one component by contributing to ...

Provoked vestibulodynia, the most common form of vulvodynia (unexplained pain of the vulva), is a prevalent, idiopathic pain disorder associated with a history of recurrent candidiasis (yeast infections). It is characterized by vulvar allodynia (painful hypersensitivity to touch) and hyperinnervation. We tested whether repeated, localized exposure of the vulva to a common fungal pathogen can lead to the development of chronic pain. A subset of female mice subjected to recurrent Candida albicans infection developed mechanical allodynia localized to the vulva. The mice with allodynia also exhibited hyperinnervation with peptidergic nociceptor and sympathetic fibers (as indicated by increased protein gene product 9.5, calcitonin gene-related peptide, and vesicular monoamine transporter 2 immunoreactivity in the vaginal epithelium). Long-lasting behavioral allodynia in a subset of mice was also observed after a single, extended Candida infection, as well as after repeated vulvar (but not hind paw) ...

Vesicular Neurotransmitter Transport Proteins: A family of neurotransmitter transporter proteins that are INTEGRAL MEMBRANE PROTEINS of the LIPID BILAYER of SECRETORY VESICLES. They are ANTIPORTERS that exchange vesicular PROTONS for cytoplasmic NEUROTRANSMITTER and play an essential role in regulating neurotransmission.

Federal drug regulators gave the go ahead for the drug, tetrabenazine, to help with one of the most prominent symptoms of Huntingtons disease, chorea.

A primary interest of our lab is to understand how nerve cells make and recycle neurotransmitters, the small molecules that they use to communicate with each other. In better defining these processes we hope to achieve our long-term goal of identifying novel sites for treatment of diseases such as epilepsy and Parkinson Disease. In our studies on neurotransmitter metabolism we have focused our efforts on transporters, a functional class of proteins that move neurotransmitters and other small molecules across membranes in cells. Transporters have many characteristics that make them excellent pharmacological targets, and not surprisingly some of the most effective treatments for neuropsychiatric disorders are directed at transporters. We are specifically focusing on two groups of transporters vesicular neurotransmitter transporters that package neurotransmitters into vesicles for release, and glutamine transporters that shuttle glutamine, a precursor for two major neurotransmitters glutamate and ...

그러나, 다른 이론은 monoamine의 정지가 총 민감성을 회복하기 위해 뇌의 monoamine 수용기를 되찾을 수 있게 하기 위해 요구 되는 것이라고 주장한다. 만약 렘 수면이 반복적으로 중단된 사람은 다음 기회에 Rebound sleep 으로 더 긴 렘 수면을 보상 받을 것이다. 그 유일한 치료방법은 일찍 자는 것이다. 특정 신경전달물질의 불균형과 관계 되어 나타나는 우울증의 경우일 때, 예리한 렘 수면 손실은 그 특정 우울증을 야기한다고 주장된다. 그러나 이것은 증명되지 않았다. 화학적 불균형의 가설을 증명할 실험도 알려지지 않았다. 대부분 항 우울증은 monoamine영향으로 인해 선택적으로 렘 수면을 제어한다. 그러나 그 효과는 오랜 기간 지나면 효과가 감소한다. 일부 연구자들은 렘 수면이 조류와 포유류의 생존을 위한 중요 기능을 돕는 것과 같은 복잡한 과정의 ...

But having dopamine floating around inside cells is actually stressful for them. The dopamine is unstable and can damage the cells machinery. Millers team has been studying a protein called VMAT2. It packages dopamine into membrane-clothed bags called vesicles. The vesicles sequester the dopamine in a safe container before it is spritzed outside to do its job of signaling to other brain cells.. Researchers already knew that having inadequate levels of VMAT2 leads to a Parkinsons-like condition in mice. But until this paper, nobody had looked at what happens if mice are forced to make more VMAT2 than usual.. Brain cells from mice with an extra VMAT2 gene take up more dopamine and package it better. Their vesicles are larger. The authors write that they hypothesized that the mice would display increased anxiety-like or mania-like behaviors, but this didnt turn out to be the case.. The mice that make extra VMAT2 were more resistant to MPTP, a toxin that is often used to produce a model of ...
