Included in this group are all natural monoamines formed by the enzymatic decarboxylation of natural amino acids.Receptors, Biogenic Amine: Cell surface proteins that bind biogenic amines with high affinity and regulate intracellular signals which influence the behavior of cells. Biogenic amine is a chemically imprecise term which, by convention, includes the catecholamines epinephrine, norepinephrine, and dopamine, the indoleamine serotonin, the imidazolamine histamine, and compounds closely related to each of these.Amine Oxidase (Copper-Containing): A group of enzymes including those oxidizing primary monoamines, diamines, and histamine. They are copper proteins, and, as their action depends on a carbonyl group, they are sensitive to inhibition by semicarbazide.Biogenic Amines: A group of naturally occurring amines derived by enzymatic decarboxylation of the natural amino acids. Many have powerful physiological effects (e.g., histamine, serotonin, epinephrine, tyramine).

The trace amine para-tyramine is structurally and functionally related to the amphetamines and the biogenic amine neurotransmitters. It is currently thought that the biological activities elicited by trace amines such as p-tyramine and the psychostimulant amphetamines are manifestations of their ability to inhibit the clearance of extracellular transmitter and/or stimulate the efflux of transmitter from intracellular stores. Here we report the discovery and pharmacological characterization of a rat G protein-coupled receptor that stimulates the production of cAMP when exposed to the trace amines p-tyramine, beta-phenethylamine, tryptamine, and ...
The catecholamines norepinephrine and epinephrine regulate important physiological functions in vertebrates. In insects; these neuroactive substances are functionally replaced by the phenolamines octopamine and tyramine. Phenolamines activate specific guanine nucleotide-binding (G) protein-coupled receptors (GPCRs). Type 1 tyramine receptors are better activated by tyramine than by octopamine. In contrast; type 2 tyramine receptors are almost exclusively activated by tyramine. Functionally; activation of type 1 tyramine receptors leads to a decrease in the intracellular concentration of cAMP ([cAMP]i) whereas type 2 tyramine receptors can mediate Ca2+ signals or both Ca2+ signals and effects on [cAMP]i. Here; we report that the American ...
The southern cattle tick (Rhipicephalus (Boophilus) microplus) is a hematophagous external parasite that vectors the causative agents of bovine babesiosis or cattle tick fever, Babesia bovis and B. bigemina, and anaplasmosis, Anaplasma marginale. The southern cattle tick is a threat to the livestock industry in many locations throughout the world. Control methods include the use of chemical acaricides including amitraz, a formamidine insecticide, which is proposed to activate octopamine receptors. Previous studies have identified a putative octopamine receptor from the southern cattle tick in Australia and the Americas. Furthermore, this putative octopamine receptor could play a role in acaricide resistance to amitraz. Recently, sequence data indicated that this putative octopamine receptor is probably a type-1 tyramine receptor (TAR1). In this study, the putative TAR1 was heterologously expressed in Chinese hamster ovary ...
The putative role of the N-terminal region of rhodopsin-like 7 transmembrane biogenic amine receptors in agonist-induced signaling has not yet been clarified despite recent advances in 7 transmembrane receptor structural biology. Given the existence of N-terminal nonsynonymous polymorphisms (R6G;E42G) within the HTR2B gene in a drug-abusing population, we assessed whether these polymorphisms affect 5-hydroxytryptamine 2B (5-HT2B) receptor in vitro pharmacologic and coupling properties in transfected COS-7 cells. Modification of the 5-HT2B receptor N terminus by the R6G;E42G polymorphisms increases such agonist signaling pathways as inositol phosphate accumulation as assessed by either classic or operational models. The N-terminal R6G;E42G mutations of the 5-HT2B receptor also increase cell proliferation and slow its desensitization kinetics compared with the wild-type receptor, further supporting a role for the N terminus in transduction efficacy. ...
One main line of research in my laboratory is aimed at understanding the structural bases of agonist and antagonist binding and specificity in the dopamine D2-like receptors and related biogenic amine receptor, how agonist binding is transduced into G protein activation, and the structural basis for G protein-coupled receptor (GPCR) oligomerization and its role in signaling. In the pursuit of these objectives we are carrying out research on the dopamine D2 receptor as well as several other GPCRs. The D2 receptor is the principal target of antipsychotic drugs used in the treatment of schizophrenia.. Other research in my laboratory is focused on determining the structural bases of the transport of substrate by the dopamine transporter and its inhibition by drugs such as cocaine and amphetamine. We are also studying regulation of the trafficking and function of the dopamine transporter and its ...

Astrocytes associate with synapses throughout the brain and express receptors for neurotransmitters that can increase intracellular calcium (Ca2+). Astrocytic Ca2+ signalling has been proposed to modulate neural circuit activity, but the pathways that regulate these events are poorly defined and in vivo evidence linking changes in astrocyte Ca2+ levels to alterations in neurotransmission or behaviour is limited. Here we show that Drosophila astrocytes exhibit activity-regulated Ca2+ signalling in vivo. Tyramine and octopamine released from neurons expressing tyrosine decarboxylase 2 (Tdc2) signal directly to astrocytes to stimulate Ca2+ increases through the octopamine/tyramine receptor (Oct-TyrR) and the transient receptor potential (TRP) channel Water witch (Wtrw), and astrocytes in turn modulate downstream dopaminergic neurons. Application of tyramine or octopamine to ...
Some neurons in Aplysia have receptors which are much more sensitive to octopamine than any other structurally related compound. Most such receptors mediate a hyperpolarizing conductance increase to K(+). These responses when considered with the octopamine content of whole ganglia and single neurons strongly suggest that octopamine is a neurotransmitter in Aplysia.
In vertebrates, biogenic amines such as dopamine, serotonin, epinephrine and norepinephrine act physiologically as neurotransmitters, neuromodulators and neurohormones to regulate many important processes. In contrast, norepinephrine and epinephrine do not appear to be present in insects, as they lack dopamine β-hydroxylase that converts dopamine to norepinephrine. In fact, their role is fulfilled by their invertebrate counterparts, the monoamines tyramine and octopamine. The insect biogenic amines carry out many of the physiological roles such as reproduction, development, growth, circadian rhythms, endocrine secretion, and behaviors. They exert their effects by binding to specific receptor proteins that belong to the superfamily of G-protein coupled receptors (GPCRs), many of which have ...
OBJECTIVES: To serially assess changes in lumbar CSF biogenic amines, radiographic characteristics, and neurological signs in 34 patients with dominantly inherited ataxia. METHODS: Mutational analysis was used to identify genetic subgroups. Annual assessment of lumbar CSF monoamine metabolites using a gas chromatographic/mass spectrometric method and morphometric measurements of the cerebellum, pons, and the cervical spinal cord on MRI were analysed for each patient and compared with normal controls. RESULTS: Patients with CAG trinucleotide repeat expansions on chromosome 6p (mutSCA1) and chromosome 14q (mutSCA3) had only about one half the normal concentrations of lumbar CSF homovanillic acid (HVA) whereas, 5-hydroxyindoleacetic acid (5-HIAA) concentrations were similar to those in age matched normal subjects. The HVA and 5-HIAA concentrations in clinically similar patients without mutSCA1 or mutSCA3 were normal. One year after the first ...

Upon pathogen infection, the nervous system regulates innate immunity to confer coordinated protection to the host. However, the precise mechanisms of such regulation remain unclear. Previous studies have demonstrated that OCTR-1, a putative G protein-coupled receptor for catecholamine, functions in the sensory neurons designated "ASH" to suppress innate immune responses in Caenorhabditis elegans. It is unknown what molecules act as OCTR-1 ligands in the neural immune regulatory circuit. Here we identify neurotransmitter octopamine (OA) as an endogenous ligand for OCTR-1 in immune regulation and show that the OA-producing RIC neurons function in the OCTR-1 neural circuit to suppress innate immunity. RIC neurons are deactivated in the presence of pathogens but transiently activated by nonpathogenic bacteria. Our data support a model whereby an octopaminergic immunoinhibitory pathway is tonically active under normal conditions to maintain immunological ...
For PCR and RACE PCR, RNA preparation from bee brains was carried out using the RNeasy Mini Kit (Qiagen, Hilden, Germany). Synthesis of cDNA, PCR and cloning of cDNA fragments was performed as described previously (Thamm et al., 2010). SMARTer RACE cDNA Amplification Kit (Takara Bio Europe/Clontech, Saint-Germain-en-Laye, France) was used to amplify the 5′-UTR of the Amtyr1 mRNAs. Primer sequences are given in Table 1. Sequencing of cloned cDNA fragments was executed by GATC Biotech (Konstanz, Germany).. For qPCR, the following regions of the brain were dissected: suboesophageal ganglion (SOG), optic lobes (OL) and mushroom bodies (MB). Samples of the different brain tissues were collected from each bee and immediately frozen in liquid nitrogen. Total RNA extraction was carried out using peqGOLD Total RNA (Peqlab, Erlangen, Germany). From each total RNA sample, two independent cDNA syntheses were performed using SuperScript III First-Strand Synthesis SuperMix for qRT-PCR (Life Technologies, ...
The purpose of the present study was to examine the combined effects of aging and lifelong ethanol exposure on the levels of monoamine neurotransmitters in different regions of the brain. This work is part of a project addressing interactions of aging and lifelong ethanol consumption in alcohol-preferring AA (Alko Alcohol) line of rats, selected for high voluntary consumption of ethanol. Intake of ethanol on the level of 4.5-5 g/kg/day for about 20 months induced only limited changes in the neurotransmitter levels; the concentration of noradrenaline was significantly reduced in the frontal cortex. There was also a trend towards lower levels of dopamine and 5-hydroxytryptamine (5-HT) in the frontal cortex, and towards a lower noradrenaline level in the dorsal cortex. Aging was associated with a decreased concentration of dopamine in the dorsal cortex and with a declining trend in the striatum. The levels of 5-HT in the limbic ...
Trace amines are an endogenous group of trace amine-associated receptor 1 (TAAR1) agonists - and hence, monoaminergic neuromodulators - that are structurally and metabolically related to classical monoamine neurotransmitters. Compared to the classical monoamines, they are present in trace concentrations. They are distributed heterogeneously throughout the mammalian brain and peripheral nervous tissues and exhibit high rates of metabolism. Although they can be synthesized within parent monoamine neurotransmitter systems, there is evidence that suggests that some of them may comprise their own independent neurotransmitter systems. Trace amines play significant roles in regulating the quantity of monoamine neurotransmitters in the synaptic cleft of ...
Spinal cord neurons active during locomotion are innervated by descending axons that release the monoamines serotonin (5-HT) and norepinephrine (NE) and these neurons express monoaminergic receptor subtypes implicated in the control of locomotion. The timing, level and spinal locations of release of these two substances during centrally-generated locomotor activity should therefore be critical to this control. These variables were measured in real time by fast-cyclic voltammetry in the decerebrate cats lumbar spinal cord during fictive locomotion, which was evoked by electrical stimulation of the mesencephalic locomotor region (MLR) and registered as integrated activity in bilateral peripheral nerves to hindlimb muscles. Monoamine release was observed in dorsal horn (DH), intermediate zone/ventral horn (IZ/VH) and adjacent white matter (WM) during evoked locomotion. Extracellular peak levels (all sites) increased above ...
Clinically effective antidepressants are thought to exert their therapeutic effects by facilitating central monoamine neurotransmission. However, recent data showing that neurokinin-1 receptor (NK1R) antagonists have antidepressant properties in both animal and clinical studies raise the possibility that classical antidepressants may also influence NK1R expression in the brain. To test this hypothesis, rats were treated with desipramine, paroxetine, venlafaxine, tranylcypromine or vehicle for 14-42 days. NK1R binding sites and mRNA were determined in a wide variety of brain areas using in situ hybridization and quantitative receptor autoradiography. In all areas examined, the abundance of NK1R binding sites was unchanged after 14 days of treatment. None of the treatments altered the number of NK1R binding sites following 42 days treatment with the exception that an increase was found in the locus coeruleus with tranylcypromine. Taken together, we report that ...
Triple reuptake inhibitors (TRIs) are compounds designed to block the serotonin, noradrenaline, and dopamine transporters, enhancing monoaminergic neurotransmission, and are seen as a promising advance in the treatment of neuropsychiatric disorders (Marks et al., 2008). GSK1360707 is a novel TRI that has been shown to be potent and selective, with excellent in vitro and in vivo profiles [see compound 17 in Micheli et al. (2010); for structure, see Teller and Furstner (2011)].. Until recently, GSK1360707 was being developed for the treatment of major depressive disorder. Current therapies for major depressive disorders typically have response rates of 50-65% (Weinmann et al., 2008) and clinically meaningful activity only after 2 to 4 weeks (Montgomery, 1997). It is hypothesized that the blockade of the three monoamine transporters will improve tolerability, speed of onset, response, and remission rates. An effective TRI could reduce the need to use multiple ...
This review summarizes the major discussion points of a symposium on stress modulation of cognitive and affective processes, which was held during the 2010 workshop on the neurobiology of stress (Boulder, CO, USA). The four discussants addressed a number of specific cognitive and affective factors that are modulated by exposure to acute or repeated stress. Dr David Morilak discussed the effects of various repeated stress situations on cognitive flexibility, as assessed with a rodent model of attentional set-shifting task, and how performance on slightly different aspects of this test is modulated by different prefrontal regions through monoaminergic neurotransmission. Dr Serge Campeau summarized the findings of several studies exploring a number of factors and brain regions that regulate habituation of various autonomic and neuroendocrine responses to repeated audiogenic stress exposures. Dr Kerry Ressler discussed a body of work exploring the modulation and extinction of fear memories in ...
Lofepramine, (N-methyl-N-[4-chlorobenzoylmethyl]-3-[10,11-dihydro-5H-dibenz(b,f)-azepin-5-yl]-propylamine hydrochloride), is a new antidepressant with low toxicity and no peripheral anticholinergic activity. Its effect on 5-hydroxytryptamine (5-HT) and noradrenaline uptake into rat brain monoaminergic neurons was studied and compared with that of other antidepressants, particularly with that of imipramine and desipramine. Lofepramine inhibited both 5-HT and noradrenaline uptake into synaptosomal fractions in vitro but was 4 times more potent in inhibiting noradrenaline than 5-HT uptake, indicating the effect resembles that of desipramine. Noradrenaline uptake was also preferentially inhibited in synaptosomes from brain of rats treated previously with lofepramine or desipramine (i.p.). Pretreatment with SKF 525A (i.p.) did not diminish the ...
Altered concentrations of monoamine neurotransmitters and metabolites have been repeatedly found in people with Down syndrome (DS, trisomy 21). Because of the limited availability of human post-mortem tissue, DS mouse models are of great interest to study these changes and the underlying neurobiological mechanisms. Although previous studies have shown the potential of Ts65Dn mice - the most widely used mouse model of DS to model noradrenergic changes, a comprehensive monoaminergic characterization in multiple brain regions has not been performed so far. Here, we used RP-HPLC with electrochemical detection to quantify (nor)adrenergic (NA, adrenaline and MHPG), dopaminergic (DA, HVA and DOPAC), and serotonergic compounds (tryptophan, 5-HT and 5-HIAA) in ten regionally dissected brain regions of Ts65Dn mice, as well as in Dp1Tyb mice - a novel DS mouse model. Comparing young adult aneuploid mice (2.5-5.5 months) with their euploid WT litter ...
TY - JOUR. T1 - Individual differences in amphetamine sensitization, behavior and central monoamines. AU - Scholl, Jamie L.. AU - Feng, Na. AU - Watt, Michael J.. AU - Renner, Kenneth J.. AU - Forster, Gina L.. PY - 2009/3/2. Y1 - 2009/3/2. N2 - Repeated amphetamine treatment results in behavioral sensitization in a high percentage of rats. Alterations to plasma corticosterone, neural monoamines and stress behavior can accompany amphetamine sensitization. Whether these changes occur following repeated amphetamine treatment in the absence of behavioral sensitization is not known. Male Sprague-Dawley rats were treated with amphetamine (2.5 mg/kg, i.p.) or saline once daily for 6 days. Amphetamine-induced locomotion and stereotypy, open-field anxiety behavior, plasma corticosterone and limbic monoamines were ...
The primary research focus of my laboratory is to understand the role of the central monoaminergic systems in brain function and behavior. More specifically we are concerned with the anatomy, physiology, and molecular biology of the brainstem noradrenergic and serotonergic efferent systems as they relate to executive functions and the sensory processing capabilities of the organism. These studies employ a broad spectrum of neuroanatomical, electrophysiological, and molecular profiling techniques including single and multi-unit extracellular recording from anesthetized and waking animals, computer based acquisition and analysis of spike train data, mapping of monoamine projections from source nuclei using retrograde tracer substances, single cell laser capture and qRT-PCR profiling of specific neuronal sub-types. The underlying theme of this work is that synaptically released norepinephrine and serotonin operate in mammalian brain as ...
A neurochemical is a small organic molecule or peptide that participates in neural activity. The science of neurochemistry studies the functions of neurochemicals. Glutamate is the most common neurotransmitter. Most neurons secrete with glutamate or GABA. Glutamate is excitatory, meaning that the release of glutamate by one cell usually causes adjacent cells to fire an action potential. (Note: Glutamate is chemically identical to the MSG commonly used to flavor food.) GABA is an example of an inhibitory neurotransmitter. Monoamine neurotransmitters: Dopamine is a monoamine neurotransmitter. It plays a key role in the functioning of the limbic system, which is involved in emotional function and control. It also is involved in cognitive processes associated with movement, arousal, executive function, body temperature regulation, and pleasure and reward, and other processes. Norepinephrine, also known as noradrenaline, is a monoamine ...

INTRODUCTION: Incessant increase in the frequency and distribution of anxiety disorders stipulates searching, research and study of the mechanism of action of new substances for their correction, including the group of 2-oxoindolin-3-glyoxylic acid derivatives. THE AIM: To research the effect of N-(1-naphthyl) amide-2-oxoindolin-3-glyoxylic acid on monoaminergic system of subjected to experimental neurosis of rats. MATERIALS AND METHODS: The experiments were performed on male Wistar rats, who have weight 180-220g and were researching the effect of 2-hydro-N-naphthalen-1-yl-2-(2-oxy-1,2-dihydroindol-3-ylidene)-acetamide (compound 18) at a dose (12 mg/kg), by intragastric drug injection of subjected to experimental neurosis rats, during 30 days (1 time in three days), for monoamines content (epinephrine, norepinephrine, dopamine and serotonin) in the blood, their decay products (homovanillic acid, vanillylmandelic acid and 5-oxyindolacetic ...
Concentrations of homovanillic acid (HVA) and 5-hydroxyindoleacetic acid (5-HIAA) were significantly higher in CSF obtained after injection of air during pneumoencephalography (PEG) than in lumbar CSF, as drawn before the injection. There was a high correlation between levels in the `mixed and lumbar samples of CSF in the case of each of the two acids. The concentration of lumbar HVA, but not that of 5-HIAA, was negatively correlated with CSF pressure. 5-HIAA levels were low in both samples of CSF in a group of epileptics, by comparison with controls. In two patients with Kufs disease and in one with Niemann-Pick disease, the concentration of HVA was very low in the lumbar sample. The application of a standardized PEG technique in the study of monoamine metabolism in man is suggested.. ...

Clinical studies have shown that lamotrigine has some beneficial antidepressant effects in major depressive episodes (Normann et al., 2002; Barbosa et al., 2003; Barbee et al., 2011), whereas currently there are no clinical studies for the use of carisbamate in mood disorders. However, carisbamate and lamotrigine present some similarities in that their main mechanism of action is at VGSCs, and they both have antidepressant-like effects in the FST model of depression; hence their comparison may allow a better understanding of their preclinical and clinical effects.. Carisbamate and lamotrigine administration for both 2 and 14 days resulted in a decrease in DRN 5-HT neuronal firing activity. The latter result may not be due to an acute increase in 5-HT, as it was reported that lamotrigine (20 mg/kg), when administered systemically, dose-dependently decreases the extracellular 5-HT levels in the DRN (Tanahashi et al., 2012). Alternatively, previous in vitro evidence indicates that ionotropic ...
Milnacipran, an antidepressant that inhibits monoamine reuptake, is widely used in the treatment of depression and fibromyalgia. In this study, we sou
Neurotransmitter transporters terminate synaptic neurotransmission by accumulating neurotransmitters once again after release in a sodium- and chloride-dependent fashion. The availability of the cloned neurotransmitter transporters has allowed investigation into the roles of these transporters in neuronal function. Molecular biological and protein engineering studies including in vitro site-directed mutagenesis, chimera formation of several transporter clones, or epitope-tagging various regions of transporter proteins, have revealed the topology and functionally mapped the transporter proteins. Monoamine neurotransmitter transporters such as those for dopamine, norepinephrine and serotonin are of interest, since they are a target of drugs of abuse and are involved in neuronal disorders including Parkinsons disease and depression. Therefore, elucidating the molecular basis of these transporters may clarify these problems and help develop treatments with which to combat these ...

Since the ADHD group and the healthy controls differed in age (F = 18.99, df = 1,64, p , .001), and since the control group itself was heterogeneous in age (children: n = 13, mean age 10.5 SD 3.9 years; adults: n = 11, mean age 36.7 SD 11.3 years; F = 62.01, df = 1,22, p , .001), we subsequently performed an ANCOVA with the covariate age. Additionally, because of differences in the ADHD group in medication status (24 without versus 18 with) and co-existing psychiatric problems (26 without versus 16 with) two further covariates were included. There were significant effects of the covariates medication status (F = 11.53, df = 1, p , .001) and additional psychiatric diagnoses (F = 7.80, df = 1, p , .01) only for N-methyl-salsolinolfree. However, the same results as obtained using ANOVA were found for all measured TIQfree derivatives (ANCOVA, Table 1). In addition to the TIQfree derivatives, also the concentrations of norsalsolinoltotal, norsalsolinolbound and N-methyl-norsalsolinoltotal ...
Article first published online: 8 SEP 2015. LINK. "The CI1 Orgueil meteorite is a highly aqueously altered carbonaceous chondrite. It has been extensively studied, and despite its extensive degree of aqueous alteration and some documented instances of contamination, several indigenous organic compounds including amino acids, carboxylic acids, and nucleobases have been detected in its carbon-rich matrix. We recently developed a novel gas chromatographic method for the enantiomeric and compound-specific isotopic analyses of meteoritic aliphatic monoamines in extracts and have now applied this method to investigate the monoamine content in Orgueil. We detected 12 amines in Orgueil, with concentrations ranging from 1.1 to 332 nmol g−1 of meteorite and compared this amine content in Orgueil with that of the CM2 Murchison meteorite, which experienced less parent-body aqueous alteration. ...
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 ...
article{9a61eb3f-8c54-482b-b9ab-17e99c703a0d, abstract = {,p,Monoamine neurotransmitters play an important role in the modulation of sensory, motor and autonomic functions in the spinal cord. Although traditionally it is believed that in mammalian spinal cord, monoamine neurotransmitters mainly originate from the brain, accumulating evidence indicates that especially when the spinal cord is injured, they can also be produced in the spinal cord. In this review, I will present evidence for a possible pathway for two-step synthesis of dopamine and serotonin in the spinal cord. Published data from different sources and unpublished data from my own ongoing projects indicate that monoenzymatic cells expressing aromatic L-amino acid decarboxylase (AADC), tyrosine hydroxylase (TH) or tryptophan hydroxylase (TPH) are present in the spinal cord and that these TH and THP cells often lie in close proximity to AADC cells. Prompted by the above evidence, I hypothesize ...
Our present neurochemical and behavioral data show, for the first time, that (1) insulin enhances cocaine-sensitive monoamine transporter function in rat NAc, thereby displaying brain-region specificity, and (2) NAc insulin reduces impulsive behavior and enhances cocaine-induced impulsivity, in agreement with the crucial role of monoamine neurotransmission in the NAc in inhibitory response control. Therefore, the pancreatic hormone insulin may play a role in inhibitory control deficits such as that observed in drug abuse, obesity, and attention deficit hyperactivity disorder (ADHD).. Considering the involvement of insulin in cognitive and motivational processes that depend on DA neurotransmission, insulin receptors and their downstream substrates (IRS-2 and PI3K) in rat brain are densely expressed in DA neurons within the ventral tegmental area (VTA) and activation of these receptors enhances PI3K activity and DAT mRNA expression (Figlewicz et al., 1994; Pardini et al., ...

AU - Katoh, Yoshimitsu. AU - Chihara, Takeshi. AU - Shimpo, Kan. PY - 2016/6/15. Y1 - 2016/6/15. N2 - Although it has been suggested that the combination of exercise and bryostatin-1 administration may induce greater functional recovery than exercise alone, the detailed molecular mechanisms are not well known. Here, we examined the relationship between this combination treatment and monoamine dynamics in the cerebral cortex peri-infarction area to promote our understanding of these molecular mechanisms. Experimental cerebral cortex infarctions were produced by photothrombosis in rats. Voluntary exercise was initiated 2 days after surgery. Motor performance was then measured using the rotarod test. Monoamine concentrations in the perilesional cortex were analyzed by ...
Major depressive disorder (MDD) is a chronic condition that affects one in six adults in the US during their lifetime. The current practice of antidepressant medication prescription is a trial-and-error process. Additionally, over a third of patients with MDD fail to respond to two or more antidepressant treatments. There are no valid clinical markers to personalize currently available antidepressant medications, all of which have similar mechanisms targeting monoamine neurotransmission. The goal of this review is to summarize the recent findings of immune dysfunction in patients with MDD, the utility of inflammatory markers to personalize treatment selection, and the potential of targeting inflammation to develop novel antidepressant treatments ...

Theories about the aetiology of unipolar depression have been dominated by biological formulations which stress the role of abnormal neurotransmitter pathways in its development and maintenance. Among the brain neurotransmitters involved in depression, serotonin (5-HT), noradrenalin (NA) and dopamine (DA; the monoamine neurotransmitter) remain the main ones which are also implicated in the regulation of sleep cycles, motivation and appetite. Recent theories about neurotransmitter dysfunction have asserted that abnormalities in receptor density and sensitivity results in changes in neurotransmitter availability. Other recent theories have implicated hyperactivity in the hypothalamic-pituitary-adrenal (HPA) axis in the development of depression. Overactivity of the HPA axis, which results in the over-production of stress hormones such as cortisol, affects the way in which monoamine neurotransmitters work in the brain. These are intriguing ideas that warrant ...
The etiopathogenesis of depression is a highly complex process characterized by several neurobiological alterations including decreased monoamine neurotransmission in the brain, dysregulated hypothalamic-pituitary-adrenal axis activity, decreased neuronal plasticity, and chronic inflammation in the brain and peripheral tissues. Experimental and clinical studies indicate that the vagus nerve may influence these processes. The importance of the vagus nerve in the etiopathogenesis of depression is further supported by its involvement in the induction of sickness behavior, as well as by clinical studies confirming a beneficial effect of vagus nerve stimulation in depressed patients. The aim of this article is to describe current knowledge of aferent and efferent vagal pathways role in the development and progression of depression ...
Amphetamine and many of its immediate derivatives (i.e., the substituted amphetamines) are also both non-competitive and competitive inhibitors of the dopamine transporter (DAT), norepinephrine transporter (NET), and serotonin transporter (SERT) proteins. Amphetamine itself has comparatively low affinity for SERT relative to DAT and NET. Consequently, amphetamine is usually classified as an NDRI instead of an SNDRI. However, the substituted amphetamines have a very diverse effects profile, and many of them have significant inhibiting effects on the SERT. Amphetamine and many of the other substituted amphetamines are inhibitors of VMAT2 and potent agonists of the trace amine-associated receptor 1 (TAAR1); agonism of TAAR1 triggers phosphorylation events that result in both non-competitive ...

This study will evaluate the effects of an experimental drug called NS2330 on Parkinsons disease symptoms and on dyskinesias (involuntary movements) that develop as a result of long-term treatment with levodopa. This drug prevents the neurotransmitter dopamine from entering nerve cells.. Patients between 18 and 75 years old who have moderately advanced Parkinsons disease and motor problems resulting from levodopa therapy may be eligible for this 5-week study. Candidates will have a complete medical history and physical examination with a detailed neurological evaluation. If needed, some patients will undergo a magnetic resonance imaging (MRI) or computerized tomography (CT) scan of the brain and a chest X-ray. All patients will have blood and urine tests and an electrocardiogram (EKG) and will take a written test for evaluation of depression.. Patients enrolled in the study will, if possible, stop taking all antiparkinson medications except levodopa (Sinemet) for one month before the study ...
The effects of chronic treatment with verapamil(VP) on monoamine release and metabolism in rat brain in vivo were compared with the effects of methamphetamine(MAP) and reserpine(RES). These drugs were administered to rats in drinking water for two weeks. The contents of monoamines (DA and 5HT) and their major metabolites(DOPAC, HVA and 5HIAA) in eight discrete brain regions were measured by HPLC-ECD. After treatment with VP, DA levels decreased in the nucleus accumbens(N.ACC) and the suprachiasmatic nucleus(SCN), but no significant changes were demonstrated in the metabolites(DOPAC, HVA). 5HT levels decreased in the N.ACC, SCN and amygdara(AMY), and 5HIAA levels decreased in the raphe dorsalis(RD). GABA contents were increased in the N.ACC. After treatment with MAP, DA levels decreased in the N.ACC, striatum(STR) and ventro-medial hypothalamic regions(VMH). No significant change was shown in the metabolites. 5HT contents decreased in the ...

The spontaneously hypertensive rat (SHR) has been proposed as an animal model for attention-deficit hyperactivity disorder (ADHD). The behavioural problems have been suggested to be secondary to altered reinforcement mechanisms in which nucleus accumbens dopaminergic activity plays an important role. Interaction between the noradrenergic and dopaminergic system in the nucleus accumbens has been implicated in the locomotor hyperactivity and impaired discriminative performance of SHR. The present study therefore investigated whether there was any change in the α2-adrenoceptor mediated inhibition of dopamine release from nucleus accumbens slices of SHR in comparison with their normotensive Wistar-Kyoto (WKY) controls. The electrically stimulated release of [3H]dopamine (DA) from nucleus accumbens slices was decreased to a similar extent by UK14,304, an α2-adrenoceptor agonist, in SHR and WKY. Basal norepinephrine (NE) levels were increased in ...

The monoamine neurotransmitters (dopamine [DA], norepinephrine [NE], epinephrine, serotonin, and histamine), the related small molecule neurotransmitter, acetylcholine (ACh), and the neuropeptides, orexin A and B, have an unusual but functionally significant organization in the brain. Their cell bodies are restricted to a small number of nuclei in the brainstem, hypothalamus, and basal forebrain, but their axons project widely throughout the central nervous system. This widely projecting organization permits each of these neurotransmitters to modulate activity in diverse circuits, sometimes in a coordinated fashion. ...
Ribosomal s6 kinase 2 is a growth factor activated serine/threonine kinase and member of the ERK signaling pathway. Mutations in the Rsk2 gene cause Coffin-Lowry syndrome, a rare syndromic form of intellectual disability. The Rsk2 KO mouse model was shown to have learning and memory defects. We focused on the investigation of the emotional behavioral phenotype of Rsk2 KO mice mainly in the IntelliCage. They exhibited an anti-depressive, sucrose reward seeking phenotype and showed reduced anxiety. Spontaneous activity was increased in some conventional tests. However, KO mice did not show defects in place learning, working memory and motor impulsivity. In addition, we found changes of the monoaminergic system in HPLC and qRT-PCR experiments. Taken together, RSK2 not only plays a role in cognitive processes but also in emotional and reward-related behaviors. ...
Serotonin is a monoamine neurotransmitter that has long been implicated in the etiology of Autism. Serotonin was originally identified as playing a role in Autism in the 1960s when a study found that a significant number of Autistic individuals had increased levels of blood platelet serotonin [18]. Subsequent studies have found that changes in serotonin levels during development can affect white and grey matter density and overall brain morphology. Research also suggests that there may be an asymmetry in serotonin synthesis in the brain, which has been associated with deficiencies in language and communication (which are two of the core symptoms of Autism) [8]. A number of serotonin transporter gene polymorphisms have also been associated with Autism however, there is not a single gene variant responsible for Autism [11]. Most studies in past have implicated excess serotonin in the aberrant development in Autism in both the brain and the periphery. However, newer studies also suggest that ...
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 ...
Serotonin (5-Hydroxytryptamine, 5-HT) is a monoamine neurotransmitter that plays important roles in physiological functions such as learning and memory, emotion, sleep, pain, motor function and endocrine secretion, as well as in pathological states including abnormal mood and cognition. Once released from presynaptic axonal terminals, 5-HT binds to receptors, which have been divided into 7 subfamilies on the basis of conserved structures and signaling mechanisms. These families include the ionotropic 5-HT3 receptors and G-protein-coupled 5-HT receptors, the 5-HT1 (Gi /Go -coupled), 5-HT2(Gq-coupled), 5-HT4/6/7 (Gs-coupled) and 5-HT5 receptors. Presynaptically localized 5-HT1B receptors are thought to be the autoreceptors that suppress excess 5-HT release. 5-HTs actions are terminated by transporter- mediated reuptake into neurons, leading to catabolism by monoamine oxidase ...

Monoamine oxidase or MAO, an enzyme that catalyzes the oxidation of monoamines, has been correlated with the regulation of various neurochemicals, such as norepinephrine, serotonin, and dopamine, which in turn, reflect behavior. A defect in the MAO-A gene, leading to a shorter version of the gene and less expression of the enzyme is linked to higher levels of norepinephrine and serotonin, since these monoamine neurotransmitters cannot be broken down at the post-synaptic cell. High levels of norepinephrine and serotonin, combined with maltreatment, lead to individuals with higher anxiety, agitation, aggression, and anti-social behavior. These behavioral disorders caused by the shorter MAO gene, also known as the warrior gene, have been associated with an increase in criminal behaviors in individuals³. Studies using animal models have shown a correlation between higher norepinephrine and serotonin levels and ...

Introduction: This study was conducted against a background of the following four points: a) increased drinking behavior in children with attention-deficit hyperactivity disorder (ADHD), b) the parallel between some behaviours associated with ADHD and with hypertension, c) the use of the spontaneously hypertensive rat as a model for ADHD, and d) similarities in the changes of neuropeptide-Y (NPY) and catecholamine in the studies of hypertension and drinking, Methods: Measures of NPY, catecholamines and electrolyte balance were compared in the plasma and urine of healthy children and those with ADHD. Drinking was monitored during three hours of neuropsychological tests over two days in 14 ADHD (mean 9.8 years-of-age) and 9 healthy children (10.6 years-of-age). Results: Patients drank 4 times more water and showed twice the levels of NPY in controls.

Recent pharmacological discovery on trace amine-associated receptor, type 1(TAAR1) has emphasized importance of trace amines in pathogenesis of psychoses, such as schizophrenia. TAAR1 has many ligands, including tyramine, β-phenylethylamine (PEA), amphetamines, and 3-iodothyronamine. So-called D-neurons are putative producer of trace amines, endogenous ligands of TAAR1. The D-neuron is defined
Consequences of pain include stimulation of some behaviors (e.g. vocalization, reflexive withdrawal from stimuli), and depression of others (e.g. exercise, and work). Pain-related decreases in behavior are among the primary diagnostic and treatment concerns for physicians, but preclinical research has often ignored this important endpoint. This discrepancy between basic research and clinical application may be one obstacle to the development of new pain treatments. In the present study, we modeled pain-related depression of behavior by examining nesting behavior in male ICR mice. Nest building is an innate mouse behavior that is sensitive to depression by a pain stimulus, and pain-related depression of nesting is blocked by the clinically effective nonsteroidal anti-inflammatory drug (NSAID) ketoprofen. This project examines effects of monoamine uptake inhibitors with varying selectivity for serotonin (5HT), norepinephrine (NE) and dopamine ...

The effect of systemic administration of desmethylimipramine (DMI), an inhibitor of the noradrenaline (NA) reuptake carrier, and of GBR 12909, an inhibitor of the dopamine (DA) reuptake carrier, on the in vivo extracellular concentrations of dopamine (DA) was studied by transcerebral dialysis in the prefrontal cortex and in the dorsal caudate of freely moving rats. In the NA-rich prefrontal cortex only DMI increased extracellular DA concentrations whereas in the dorsal caudate only GBR 12909 was effective. Haloperidol increased extracellular DA concentrations more effectively in the dorsal caudate than in the prefrontal cortex. Pretreatment with DMI, which failed to modify the effect of haloperidol in the dorsal caudate, potentiated its action in the prefrontal cortex. The reverse was obtained after GBR 12909 + haloperidol in the two areas. 6-hydroxydopamine lesioning of the dorsal NA bundle ...

This study has investigated the transcriptional regulation of MAO A and B genes. MAO A and B are a crucial pair of oxidative isoenzymes, which degrade biogenic and dietary amines, including monoamine neurotransmitters, and produce hydrogen peroxide. Abnormal MAO A or B activity has been implicated in numerous neurological and psychiatric disorders. These two isoenzymes have different but overlapping substrate and inhibitor selectivity. There is a 70% amino acid sequences identity and different tissue- and cell-specific expression between the two enzymes. MAO A and B promoters share approximately 60% sequence identity with distinct organization. Both MAO A and B are regulated by Sp-family proteins, such as Sp1 and Sp3. MAO B is uniquely regulated by protein kinase C and mitogen-activated protein kinase signaling pathways, whereas MAO A is involved in the c-Myc-induced proliferative signaling pathway.; This study further demonstrates the ...
The findings concerning the probable importance of the monoamine oxidases in the sleep mechanism raise the hope that it may soon be possible to build a bridge between neurophysiology and biochemistry in the investigation of sleep. If it is indeed a fact that these enzymes play an important role in sleep, this tends to strengthen the hypothesis that serotonin and noradrenalin, which are monoamines, are involved in the two states of sleep-serotonin in light sleep and noradrenalin in paradoxical sleep. There are other bits of chemical evidence that support the same view. For example, the drug reserpine, which is known to prevent the accumulation of monoamines at places where these compounds are usually deposited, has been found to be capable of producing some specific electrical signs of paradoxical sleep in experimental animals. Further, the injection of certain precursors involved in the synthesis of ...
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 ...
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 ...

In summary, we show that deletion of the MIF gene led to reduced behavioural despair in mice of both sexes, as assessed in the FST and with a similar trend in the TST. The IFN-γ mRNA levels were reduced in the hippocampus of the MIF KO mice, and sex-specific alterations of IFN-γ in the PFC and blood serum were found. Moreover, we observed significant changes in the monoamine- and monoamine metabolite levels in the MIF KO mice. Importantly, lower serum IFN-γ levels predicted higher DA levels, and the DA levels were directly associated with the reduced behavioural despair in the FST in all animals. The results we observed in the TST were very similar to the results in the FST, although they were only trending towards significance. Thus, in this study we have detected a reduced behavioural despair by deleting the MIF gene. The effect was mediated by decreased levels of IFN-γ, which predicted higher levels of brain dopamine.. Our finding that the MIF KO mice ...

Data also have demonstrated that inflammatory cytokines can interact with multiple pathways known to be involved in the development of depression, including monoamine metabolism, neuroendocrine function, synaptic plasticity, and neurocircuits relevant to mood regulation …. Psychosocial stress, diet, obesity, a leaky gut and an imbalance between regulatory and pro-inflammatory T cells also contribute to inflammation and may serve as a focus for preventative strategies relevant to both the development of depression and its recurrence.". This indicates that depression occurs as a result of the attempt of the body to protect against inflammation, and this involves hormones and neurotransmitters.. Depressive symptoms linked to chronic inflammation include metabolic changes, flat mood, slowed thinking, avoidance, and alterations in perception..

Phentermine has some similarity in its pharmacodynamics with its mum or dad compound, amphetamine, as they each are TAAR1 agonists,[six] wherever the activation of TAAR1 in monoamine neurons facilitates the efflux or, release into the synapse, of those neurochemicals; at clinically pertinent doses, phentermine largely acts to be a releasing agent of norepinephrine in neurons, Even though, to some lesser extent, it releases dopamine and serotonin into synapses likewise.[5][7] Phentermine may set off the discharge of monoamines from VMAT2, which can be a typical pharmacodynamic influence among the substituted amphetamines ...
The brain contains billions and billions of neurons. These cells communicate with one another by releasing small endogenous chemical messengers, called neurotransmitters, into the synapse, where they are then taken up by specific receptors on neighboring cells. There are many types of neurotransmitters in the brain-what they have in common is that they are produced inside a neuron, released into the synapse, and then cause an excitatory or inhibitory effect on receptor cells, helping to propagate or downgrade action potentials.[i]. Neurotransmitters are often classified into two types: small-molecule transmitters and neuropeptides. Small-molecule transmitters can be further differentiated into monoamines like dopamine and amino acids like glutamate. The neuropeptide class includes endorphins, insulin, and oxytocin. Typically, small-molecule transmitters are direct actors on neighboring cells. Neuropeptides, on the other hand, are better suited for more ...
