Brain Res 2023; 1804:148249. [PMID: 36682705 DOI: 10.1016/j.brainres.2023.148249] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Revised: 01/09/2023] [Accepted: 01/17/2023] [Indexed: 01/21/2023]
Abstract
Lower platelet monoamine oxidase (MAO) activity has been associated with problem behaviors, including criminal behavior, but not all studies agree. We have examined platelet MAO activity and antisocial behavior involving police contact in a longitudinal birth cohort study. The sample included both birth cohorts (original n = 1238) of the Estonian Children Personality Behavior and Health Study. Platelet MAO activity was measured at ages 15, 18 and 25 radioenzymatically with β-phenylethylamine as the substrate. Police contacts were self-reported in an interview and drug use in a questionnaire filled in during a laboratory visit. In cross-sectional analyses, males with the record of antisocial behavior had lower platelet MAO activity. In longitudinal mixed-effect regression models, this association was found to be independent of smoking. Furthermore, including smoking in the model revealed lower platelet MAO activity also in females with past antisocial behaviour. A further exploratory regression analysis with antisocial behavior at two levels of frequency and consideration of self-reported use of illicit drugs either in a single occasion or repeatedly demonstrated some "dose-dependency" in the relationship of antisocial behavior and platelet MAO activity. Platelet MAO activity was lower in male but not female subjects with basic education level as compared to secondary and higher education, but it was not related to non-verbal intelligence. Neither was platelet MAO activity associated with socio- economic status. In conclusion, antisocial behavior as occurring in general population is associated with low platelet MAO activity that probably reflects low capacity of the serotonergic system.

Cerebrospinal Fluid Biomarkers in Patients With Unipolar Depression Compared With Healthy Control Individuals: A Systematic Review and Meta-analysis. JAMA Psychiatry 2022; 79:571-581. [PMID: 35442429 PMCID: PMC9021989 DOI: 10.1001/jamapsychiatry.2022.0645] [Citation(s) in RCA: 33] [Impact Index Per Article: 16.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2021] [Accepted: 02/23/2022] [Indexed: 01/21/2023]
Abstract
Importance Depression has been associated with alterations in neurotransmitters, hormones, and inflammatory and neurodegenerative biomarkers, and biomarkers quantified in the cerebrospinal fluid (CSF) are more likely to reflect ongoing biochemical changes within the brain. However, a comprehensive overview of CSF biomarkers is lacking and could contribute to the pathophysiological understanding of depression. Objective To investigate differences in quantified CSF biomarkers in patients with unipolar depression compared with healthy control individuals. Data Sources PubMed, EMBASE, PsycINFO, Cochrane Library, Web of Science, and ClinicalTrials.gov were searched for eligible trials from database inception to August 25, 2021. Study Selection All studies investigating CSF biomarkers in individuals 18 years and older with unipolar depression and healthy control individuals were included. One author screened titles and abstracts, and 2 independent reviewers examined full-text reports. Studies that did not include healthy control individuals or included control individuals with recent hospital contacts or admissions that might affect CSF biomarker concentrations were excluded. Data Extraction and Synthesis Data extraction and quality assessment were performed by 2 reviewers following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guidelines. Meta-analyses were performed using standardized mean differences (SMDs) calculated with random-effects models. A third investigator was consulted if the 2 reviewers reached different decisions or when in doubt. Main Outcomes and Measures Quantifiable CSF biomarkers. Results A total of 167 studies met eligibility criteria, and 97 had available data and were included in the meta-analysis. These 97 studies comprised 165 biomarkers, 42 of which were quantified in 2 or more studies. CSF levels of interleukin 6 (7 studies; SMD, 0.35; 95% CI, 0.12 to 0.59; I2 = 16%), total protein (5 studies; SMD, 0.53; 95% CI, 0.35 to 0.72; I2 = 0%), and cortisol (2 studies; SMD, 1.23; 95% CI, 0.89 to 1.57; I2 = 0%) were higher in patients with unipolar depression compared with healthy control individuals, whereas homovanillic acid (17 studies; SMD, -0.26; 95% CI, -0.39 to -0.14; I2 = 11%), γ-aminobutyric acid (4 studies; SMD, -0.50; 95% CI, -0.92 to -0.08; I2 = 55%), somatostatin (5 studies; SMD, -1.49; 95% CI, -2.53 to -0.45; I2 = 91%), brain-derived neurotrophic factor (3 studies; SMD, -0.58; 95% CI, -0.97 to -0.19; I2 = 0%), amyloid-β 40 (3 studies; SMD, -0.80; 95% CI, -1.14 to -0.46; I2 = 0%), and transthyretin (2 studies; SMD, -0.82; 95% CI, -1.37 to -0.27; I2 = 0%) were lower. The remaining 33 biomarkers had nonsignificant results. Conclusions and Relevance The findings of this systematic review and meta-analysis point toward a dysregulated dopaminergic system, a compromised inhibitory system, hypothalamic-pituitary-adrenal axis hyperactivity, increased neuroinflammation and blood-brain barrier permeability, and impaired neuroplasticity as important factors in depression pathophysiology.

Abstract
RATIONALE Platelet monoamine oxidase (MAO) activity, a marker of central serotonergic capacity, has been associated with a variety of problem behaviours. However, studies on platelet MAO activity and addictive drugs have not consistently linked MAO activity with addiction or reported to predict illicit substance use initiation or frequency. OBJECTIVES Platelet MAO activity and illicit drug use was examined in a longitudinal birth cohort study. METHODS The sample included both birth cohorts (original n = 1238) of the Estonian Children Personality Behaviour and Health Study. Longitudinal association from age 15 to 25 years between platelet MAO activity and lifetime drug use was analysed by mixed-effects regression models. Differences at ages 15, 18 and 25 were analysed by t-test. Cox proportional hazard regression analysis was used to assess the association between platelet MAO activity and the age of drug use initiation. RESULTS Male subjects who reported at least one drug use event had lower platelet MAO activity compared to nonusers, both in cross-sectional and longitudinal analyses. Males with low platelet MAO activity had started to use drugs at a younger age. Moreover, in male subjects who had experimented with illicit drugs only once in lifetime, low platelet MAO activity was also associated with higher risk at a younger age. In females, platelet MAO activity was not associated with drug use. CONCLUSION In males, low platelet MAO activity is associated with drug abuse primarily owing to risk-taking at early age.

Sharma R, Tikka SK, Yadav AK, Bhute AR, Dhamija P, Bastia BK. Cerebrospinal fluid monoamine metabolite concentrations in suicide attempt: A meta-analysis. Asian J Psychiatr 2021; 62:102711. [PMID: 34090249 DOI: 10.1016/j.ajp.2021.102711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Revised: 05/10/2021] [Accepted: 05/21/2021] [Indexed: 10/21/2022]
Abstract
AIM The purpose of this meta-analysis was to critically examine the data from individual studies on CSF neurotransmitter metabolites to see whether there were consistencies in the results of the comparison of suicide attempters and psychiatric controls and of the comparison of attempted suicides using violent versus nonviolent methods. METHOD Systematic literature search across different electronic databases using PubMed/Google Scholar/EMBASE/Cochrane library was conducted for studies that reported concentration of CSF-neurotransmitter metabolites: 5-hydroxyindoleacetic acid (5-HIAA), homovanillic acid (HVA) and 3-methoxy-4-hydroxy phenylglycol (MHPG) in suicide attempters, from January'1981 to November'2020. Standardized mean differences (SMDs) and corresponding 95 % confidence interval (CIs) were deduced for outcome measures. I2 statistics were used to assess heterogeneity within studies. Data were analyzed using STATA software. RESULTS A total of 36 studies (N = 1987 attempted suicide and N = 1235 psychiatry control) were included for the meta-analysis. We found CSF levels of all the 3 metabolites i.e. 5-HIAA (SMD= -0.43; 95 %CI: -0.61, -0.24), HVA (SMD= -0.16; 95 %CI: -0.33, -0.00) and MHPG (SMD= -0.33; 95 %CI: -0.71, -0.05) were lower in suicide attempters. While the findings were consistent for 5-HIAA, they were inconsistent for the HVA and MHPG. CSF levels of 5-HIAA (SMD= -0.66; 95 %; CI: -1.01, -0.31), HVA (SMD= -0.14; 95 %CI: -0.45, 0.16) and MHPG (SMD= -0.12; 95 %CI: -0.56, 0.31) were significantly lower in violent suicide attempters than non-violent attempters. No significant publication bias found in any study. CONCLUSION We found a significant association between lower levels of CSF 5-HIAA in suicide attempters, particularly the violent ones, compared to psychiatric controls, whereas findings from CSF HVA and MHPG were inconsistent.

Abstract
Psychiatric diseases, like depression, largely affect the central nervous system (CNS). While the underlying neuropathology of depressive illness remains to be elucidated, several hypotheses have been proposed as molecular underpinnings for major depressive disorder, including the monoamine hypothesis and the cytokine hypothesis. The monoamine hypothesis has been largely supported by the pharmaceuticals that target monoamine neurotransmitters as a treatment for depression. However, these antidepressants have come under scrutiny due to their limited clinical efficacy, side effects, and delayed onset of action. The more recent, cytokine hypothesis of depression is supported by the ability of immune-active agents to induce "sickness behaviour" akin to that seen with depression. However, treatments that more selectively target inflammation have yielded inconsistent antidepressive results. As such, neither of these hypotheses can fully explain depressive illness pathology, implying that the underlying neuropathological mechanisms may encompass aspects of both theories. The goal of the current review is to integrate these two well-studied hypotheses and to propose a role for histamine as a potential unifying factor that links monoamines to cytokines. Additionally, we will focus on stress-induced depression, to provide an updated perspective of depressive illness research and thereby identify new potential targets for the treatment of major depressive disorder.

Abstract
BACKGROUND It remains unclear whether the dopaminergic and noradrenergic systems may be implied in suicide attempt risk. In addition, although the serotonergic system has been extensively studied, no formal meta-analysis has been performed to examine its association with suicide attempt. METHODS Using PRISMA methodology, we performed a systematic literature review and random-effects meta-analyses of the differences in cerebrospinal fluid (CSF) levels of 5-HIAA, HVA and MHPG between suicide attempters and individuals who never attempted suicide. RESULTS We identified 30 studies including 937 suicide attempters and 1128 non-attempters; 29 of them measured CSF levels of 5-HIAA, 22 measured CSF levels of HVA and 14 measured CSF levels of MHPG. CSF levels of 5-HIAA and HVA were significantly lower in suicide attempters than in non-attempters [SMD = -0.43 (95% CI: -0.71 to -0.15; p < 0.01) and SMD = -0.45 (95% CI: -0.72 to -0.19; p < 0.01), respectively]. We did not find a significant association between CSF MHPG levels and suicide attempt. LIMITATIONS Our analyses relied on a limited number of studies of good quality and most studies included small sample sizes. CONCLUSION Both serotonin and dopamine systems may play a role in suicide attempt risk. Our findings suggest that a silo approach to biomarkers should be phased out in favor of the study of multiple systems in parallel and in the same populations to progress in the identification of the biological components independently associated with suicide risk, with the goal of identifying new treatment targets and improving suicide risk prediction.

Platelet MAO activity and COMT Val158Met genotype interaction predicts visual working memory updating efficiency. Behav Brain Res 2021; 407:113255. [PMID: 33745984 DOI: 10.1016/j.bbr.2021.113255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Revised: 03/10/2021] [Accepted: 03/15/2021] [Indexed: 11/24/2022]
Abstract
The exact mechanism how serotonergic and dopaminergic systems relate to one another in working memory (WM) updating is unknown. Platelet monoamine oxidase (MAO) has been used as a marker for central serotonergic capacity, and catechol-O-methyltransferase (COMT) as a marker for central dopaminergic capacity. This study aimed to describe the interaction of platelet MAO activity and COMT Val158Met genotype in visual working memory updating: the ability to replace old information with new within hundreds of milliseconds. Previous studies suggest that platelet MAO activity and COMT Val158Met genotype could have an interaction effect on working memory. However, there are no studies that have directly examined the interaction of these biomarkers in WM updating. We used a 2-back updating task with facial expressions and defined updating efficiency as response times for correct responses. 455 subjects from a population representative sample were included. Mixed models were used for data analysis with an aim to study the interaction of COMT Val158Met genotype (Val/Val, Val/Met and Met/Met) and the level of MAO activity (high vs low). Education, IQ, sex, simple reaction times, and overall updating accuracy were included as covariates. We found that the effect of COMT Val158Met on updating efficiency depends on the level of platelet MAO activity. Low MAO in contrast to high MAO was associated with an increase in updating efficiency in Val/Met but a decrease in Met/Met. The results are discussed in the context of serotonin and dopamine functions in brain regions related to WM. The findings support the view that serotonin modulates dopaminergic activation in updating and contribute to understanding the role of serotonin in PFC, top-down inhibitory signals, and its interactions with dopamine in WM processes.

Abstract
INTRODUCTION Analyses of cerebrospinal fluid (CSF) metabolites in large, healthy samples have been limited and potential demographic moderators of brain metabolism are largely unknown. OBJECTIVE Our objective in this study was to examine sex and race differences in 33 CSF metabolites within a sample of 129 healthy individuals (37 African American women, 29 white women, 38 African American men, and 25 white men). METHODS CSF metabolites were measured with a targeted electrochemistry-based metabolomics platform. Sex and race differences were quantified with both univariate and multivariate analyses. Type I error was controlled for by using a Bonferroni adjustment (0.05/33 = .0015). RESULTS Multivariate Canonical Variate Analysis (CVA) of the 33 metabolites showed correct classification of sex at an average rate of 80.6% and correct classification of race at an average rate of 88.4%. Univariate analyses revealed that men had significantly higher concentrations of cysteine (p < 0.0001), uric acid (p < 0.0001), and N-acetylserotonin (p = 0.049), while women had significantly higher concentrations of 5-hydroxyindoleacetic acid (5-HIAA) (p = 0.001). African American participants had significantly higher concentrations of 3-hydroxykynurenine (p = 0.018), while white participants had significantly higher concentrations of kynurenine (p < 0.0001), indoleacetic acid (p < 0.0001), xanthine (p = 0.001), alpha-tocopherol (p = 0.007), cysteine (p = 0.029), melatonin (p = 0.036), and 7-methylxanthine (p = 0.037). After the Bonferroni adjustment, the effects for cysteine, uric acid, and 5-HIAA were still significant from the analysis of sex differences and kynurenine and indoleacetic acid were still significant from the analysis of race differences. CONCLUSION Several of the metabolites assayed in this study have been associated with mental health disorders and neurological diseases. Our data provide some novel information regarding normal variations by sex and race in CSF metabolite levels within the tryptophan, tyrosine and purine pathways, which may help to enhance our understanding of mechanisms underlying sex and race differences and potentially prove useful in the future treatment of disease.

Abstract
RésuméDes troubles du fonctionnement sérotoninergique ont été impliqués dans de nombreuses pathologies ou dysrégulations du système nerveux central: trouble dépressif, trouble anxieux, schizophrénie, psychopathie, agressivité, boulimie, éthylisme, etc.Le rôle de cette amine dans l’inhibition de la survenue de certains comportements est décrit depuis longtemps. Chez l’animal, ce rôle semble organiser la capacité à différer une conduite et/ou à tolérer sans réponse comportementale une situation de contrainte. Chez l’homme, la sérotonine semble réguler une capacité à contrôler les réponses impulsives dans le cadre des troubles très différents tels que passage à l’acte suicidaire, conduite boulimique, compulsions itératives, conduite éthylique, etc. Les inhibiteurs du recaptage de la sérotonine semblent améliorer l’existence de ces troubles de façon transnosologique.Nous faisons l’hypothèse que certains diagnostics pourraient être la conséquence d’un fonctionnement «limite» sur le plan biologique facilitant le passage à l’acte et des troubles de personnalité. Aucune des deux dimensions ne serait en soi pathologique. Le manque d’adaptabilité de certains fonctionnements mentaux (caractère, personnalité) ajoutée à un fonctionnement biologique «limite” (difficulté à différer sa réponse) seraient par leur coexistence responsables de la décompensation qui aboutit à ce qu’on appelle un diagnostic.

Abstract
Background Monoamine oxidase (MAO) activity has been traditionally implicated in blood pressure through its effects on biogenic amine levels such as catecholamines, serotonin, and dopamine. Nowadays, this role is considered relegated to side‐effects such as orthostatic hypotension and/or hypertensive crisis derived from MAO‐inhibitory treatments in patients with psychiatric disease. Methods In the present work we have found an association between a polymorphic variant of MAOB gene and arterial hypertension in obese hypogonadic patients. The study cases comprised a series of 219 nondiabetic males with a body mass index ≥30 kg/m2 and aged <45 years. Hypogonadism was defined as subnormal testosterone concentrations, when free testosterone values ranged <65 pg/ml. Results MAOB rs3027452‐A allele carriers were significantly over‐represented among hypertensive (HT) patients (25.49%) in comparison to either the non‐HT patients (10%, OR = 3.079 CI95 [1.364–6.952], p = .005, Chi‐square test) and the control population series of nonobese nor hypogonadic males (also 10%, p = .003 Chi‐square test). Upon adjusted, an independent association was shown with the hypogonadic group with hypertension when compared with nonhypertensive hypogonadics (Beta = 3.653, p = .005). When quantitative analysis was performed, hypertensive patients harboring rs3027452‐A allele showed higher systolic blood pressure values (p = .038, Mann–Whitney U‐test) as well as an increased Systolic‐Diastolic range despite following HT treatment (∆mmHg 54 vs. 48 for rs3027452‐A and rs3027452‐G respectively, p‐value .019, Mann–Whitney U‐test). Previous studies on MAOB revealed that rs3027452‐A allele has been correlated to a lower activity of the enzyme, what gives a functional evidence over our observation. Conclusion If this result could be extrapolated to other hypertensive patient groups, it would implicate a review of the markers and therapeutic targets on human hypertension.

Abstract
Bulimia Nervosa (BN) is a serious eating disorder, which affects 0.8-2.9% of the young population. The etiology is unknown and biomarkers would support in understanding the pathophysiology of BN, and in identifying BN patients that may benefit from medical treatment. This systematic review aims to answer whether (a) BN deviate from healthy controls in terms of serotonin (5-HT) biomarkers in blood, and whether (b) blood-based 5-HT biomarkers could be used to tailor psychopharmacological treatment in BN. A literature search using PubMed, PsycINFO and Embase was done using the following search terms: "Bulimia Nervosa" AND "serotonin" AND "blood" OR "plasma" OR "serum". 32 studies were included in this systematic review. Several biomarkers and challenge tests were identified and all studies described an association with BN and dysregulation of the 5-HT system compared to healthy controls. Several studies pointed to an association also to borderline symptoms in BN. BN deviate from healthy controls in terms of 5-HT biomarkers in blood supporting an abnormal 5-HT system in BN. 5-HT biomarkers and associated methods could be used to tailor treatment in BN although as yet, most tests described are unpractical for bedside use.

Abstract
BACKGROUND Although investigated for decades, surprisingly no systematic review has ever been published on monoamines concentrations in cerebrospinal fluid (CSF) in major depressive disorder (MDD) versus healthy individuals (HC). METHODS We did a systematic review and meta-analyses according to the PRISMA Statement based on comprehensive database searches for studies on CSF biomarkers of monoamines and their precursor and/or metabolites, and glutamine, glutamate and GABA in MDD versus HC. Risk of bias was systematically assessed. RESULTS A total of 23 studies were included. Statistically significantly decreased levels between MDD and HC were found regarding CSF 5-HIAA (n = 2/13 (15%)), HVA (n = 2/11 (18%)), MHPG (n = 1/8 (13%)), and GABA (n = 2/4 (50%)), while increased levels were reported regarding NE (n = 1/2 (50%)), MHPG (n = 1/8 (13%)) and DOPEG (n = 1/1 (100%)). A majority of the studies found no statistically significant differences between MDD and HC regarding CSF 5-HIAA, HVA, NE, MHPG, glutamine, glutamate and GABA. Meta-analyses showed: 5-HIAA (-3.85, -8.89, 1.19, 0.14), HVA (-18.02, -30.99, -5.04, 0.01), MHPG (0.11, -2.96, 3.17, 0.95) and GABA (-33.20, -51.79, -14.62, 0.00) (mean difference, lower 95% CL, upper 95% CL, p-value). Most studies were influenced by risk of bias mainly due to small sample sizes, and not considering potential confounders as age, gender, severity of depression, body height and position during lumbar puncture, analytics of biomarkers and medication. CONCLUSION The evidence for CSF 5-HIAA, HVA, NE, MHPG, DOPEG and GABA being related to the pathophysiology of MDD is poor. Future controlled studies of monoamines or metabolites should validate the null i.e., that the concentrations of these compounds are not abnormal in MDD.

Abstract
Altered monoaminergic functions have been implicated in the pathophysiology of depressive disorder. However, previously reported cerebrospinal fluid (CSF) monoamine metabolite concentrations in major depression have been inconsistent. We performed a meta-analysis of historic evidence to determine whether CSF monoamine metabolite levels were different between patients with depression and normal controls, and could be used as depression biomarkers. Relevant studies that investigated CSF 5-hydroxyindoleacetic acid (5-HIAA), homovanillic acid (HVA), and 3-methoxy-4-hydroxyphenylglycol (MHPG) levels in patients with depression and normal controls were identified in PubMed, Web of Science, PsycINFO, and Embase databases through September 5, 2017, using a synonymous search for depression, CSF, normal, control, and each monoamine metabolite name, and in the reference lists of the acquired articles. Obtained records were individually scrutinized for eligibility. Our search strategy identified 26 studies, including our own. We employed random effects modeling and adopted "Hedges's g" as an index of effect size. In the meta-analyses, no significant difference was observed in CSF 5-HIAA or MHPG levels between patients with depressive disorder and controls. In contrast, CSF HVA was significantly decreased in patients with depression (Hedges's g = -0.30, P = 0.0000025), and these results remained significant after patients with bipolar disorder were excluded (Hedges's g = -0.37, P = 0.000061). In the meta-regression, sex was significantly associated with the Hedges's g of CSF HVA (Q = 4.41, P = 0.036). This meta-analysis revealed that only CSF HVA, and not 5-HIAA or MHPG, levels were decreased in depressive disorder. The reduction in the CSF HVA concentration in patients with depression may guide future studies on depression and serve as a useful biomarker of depressive disorder.

Abstract
Alterations in monoaminergic signaling are suggested as key aspects of the pathophysiology in bipolar disorder and ADHD, but it is not known if the monoamine metabolic profile differs between these disorders. One method to study monoaminergic systems in humans is to measure monoamine end-point metabolite concentrations in cerebrospinal fluid (CSF). Here, we analyzed CSF monoamine metabolite concentrations in 103 adults with bipolar disorder, 72 adults with ADHD, and 113 controls. Individuals with bipolar disorder had significantly higher homovanillic acid (HVA, 264 ± 112 nmol/L, p < 0.001) and 5-hydroxyindoleacetic acid (5-HIAA, 116 ± 42 nmol/L, p = 0.001) concentration, but lower 3-methoxy-4-hydroxyphenylethyleneglycol (MHPG, 38 ± 8 nmol/L, p < 0.001) concentrations than controls (HVA, 206 ± 70 nmol/L; 5-HIAA, 98 ± 31 nmol/L; and MHPG, 42 ± 7 nmol/L). Higher HVA concentrations were associated with a history of psychosis in the bipolar disorder sample. Subjects with ADHD had higher HVA (240 ± 94 nmol/L, p < 0.001) concentrations compared with controls. In addition, SSRI treatment was associated with lower 5-HIAA concentrations in both patient groups. A power analysis indicated that for within-group comparisons, only large effects would be reliably detectable. Thus, there may be moderate-to-small effects caused by medication that were not detected due to the limited size of the sub-groups in these analyses. In conclusion, the present study suggests disorder-specific alterations of CSF monoamine metabolite concentrations in patients with bipolar disorder and ADHD compared with controls; these differences were independent of acute symptoms and medication effects.

Abstract
Subjects with schizophrenia or conduct disorder display a lifelong pattern of antisocial, aggressive and violent behavior and agitation. Monoamine oxidase (MAO) is an enzyme involved in the degradation of various monoamine neurotransmitters and neuromodulators and therefore has a role in various psychiatric and neurodegenerative disorders and pathological behaviors. Platelet MAO-B activity has been associated with psychopathy- and aggression-related personality traits, while variants of the MAOA and MAOB genes have been associated with diverse clinical phenotypes, including aggressiveness, antisocial problems and violent delinquency. The aim of the study was to evaluate the association of platelet MAO-B activity, MAOB rs1799836 polymorphism and MAOA uVNTR polymorphism with severe agitation in 363 subjects with schizophrenia and conduct disorder. The results demonstrated significant association of severe agitation and smoking, but not diagnosis or age, with platelet MAO-B activity. Higher platelet MAO-B activity was found in subjects with severe agitation compared to non-agitated subjects. Platelet MAO-B activity was not associated with MAOB rs1799836 polymorphism. These results suggested the association between increased platelet MAO-B activity and severe agitation. No significant association was found between severe agitation and MAOA uVNTR or MAOB rs1799836 polymorphism, revealing that these individual polymorphisms in MAO genes are not related to severe agitation in subjects with schizophrenia and conduct disorder. As our study included 363 homogenous Caucasian male subjects, our data showing this negative genetic association will be a useful addition to future meta-analyses.

Abstract
The present study was designed to understand the cigarette smoking-induced alterations in hormones and the resulting changes in platelet serotonin (5-hydroxytryptamine, 5-HT) and monoamine oxidase (MAO-B) activity in chronic smokers. Human male volunteers aged 35 ± 8 years, were divided into two groups, namely controls and smokers (12 ± 2 cigarettes per day for 7-10 years). Results showed that cigarette smoking significantly (p < 0.05) elevated plasma triiodothyronine (T3), cortisol and testosterone levels with significant (p < 0.05) reduction in plasma tryptophan and thyroxin (T4). Moreover, smokers showed reduced platelet 5-HT levels and MAO-B activity. In smokers, plasma cortisol was negatively correlated with tryptophan (r = -0.386), platelet MAO-B (r = -0.264), and 5-HT (r = -0.671), and positively correlated with testosterone (r = 0.428). However, testosterone was negatively correlated with platelet MAO-B (r = -0.315), and 5-HT (r = -.419) in smokers. Further, smokers plasma T3 levels were negatively correlated with platelet MAO-B (r = -0.398), and 5-HT (r = -0.541), whereas T4 levels were positively correlated with platelet MAO-B (r = 0.369), and 5-HT (r = 0.454). In conclusion, our study showed that altered testosterone and cortisol levels may aggravate behavior, mood disturbances and symptoms of depression by decreasing platelet 5-HT and MAO-B activity in smokers.

Abstract
AbstractAnimal research suggests that central serotonergic neurons are involved in behavioral suppression, particularly anxiety-related inhibition. The hypothesis linking decreased serotonin transmission to reduced anxiety as the mechanism in the anxiolytic activity of benzodiazepines conflicts with most clinical observations. Serotonin antagonists show no marked capacity to alleviate anxiety. On the other hand, clinical signs of reduced serotonergic transmission (low 5-HIAA levels in the cerebrospinal fluid) are frequently associated with aggressiveness, suicide attempts, and increased anxiety. The target article attempts to reconcile such human and animal findings by investigating whether anxiety reduction or increased impulsivity is more Likely to account for animal behavioral changes associated with decreased serotonergic transmission. The effects of manipulating central serotonin in experimental anxiety paradigms in animals (punishment, extinction, novelty) are reviewed and compared with the effects of antianxiety drugs. Anxiety seems neither necessary nor sufficient to induce control by serotonergic neurons on behavior. Further evidence suggests that behavioral effects of anxiolytics thought to be mediated by decreases in anxiety are not caused by the ability of these drugs to reduce serotonin transmission. Blockade of serotonin transmission, especially at the level of the substantia nigra, results in a shift of behavior toward facilitation of responding. This behavioral shift is particularly marked when there is competition between acting and restraining response tendencies and when obstacles prevent the immediate attainment of an anticipated reward. It is proposed that serotonergic neurons are involved not only in behavioral arousal but also in enabling the organism to arrange or tolerate delay before acting. Decreases in serotonin transmission seem to be associated with the increased performance of behaviors that are usually suppressed, though not necessarily because of the alleviation of anxiety, which might contribute to the suppression.

Abstract
AbstractA comparative method of studying the biological bases of personality compares human trait dimensions with likely animal models in terms of genetic determination and common biological correlates. The approach is applied to the trait of sensation seeking, which is defined on the human level by a questionnaire, reports of experience, and observations of behavior, and on the animal level by general activity, behavior in novel situations, and certain types of naturalistic behavior in animal colonies. Moderately high genetic determination has been found for human sensation seeking, and marked strain differences in rodents have been found in open-field behavior that may be related to basic differences in brain neurochemistry. Agonistic and sociable behaviors in both animals and humans and the trait measure of sensation seeking in humans have been related to certain common biological correlates such as gonadal hormones, monoamine oxidase (MAO), and augmenting of the cortical evoked potential.The monoamine systems in the rodent brain are involved in general activity, exploratory behavior, emotionality, socialization, dominance, sexual and consummately behaviors, and intracranial self-stimulation. Preliminary studies have related norepinephrine and enzymes involved in its production and degradation to human sensation seeking. A model is suggested that relates mood, behavioral activity, sociability, and clinical states to activity of the central catecholamine neurotransmitters and to neuroregulators and other transmitters that act in opposite ways on behavior or stabilize activity in the arousal systems. Stimulation and behavioral activity act on the catecholamine systems in a brain–behavior feedback loop. At optimal levels of catecholamine systems activity (CSA) mood is positive and activity and sociability are adaptive. At very low or very high levels of CSA mood is dysphoric, activity is restricted or stereotyped, and the organism is unsocial or aggressively antisocial. Novelty, in the absence of threat, may be rewarding through activation of noradrenergic neurons.

Abstract
Platelet monoamine oxidase B (MAO-B) has been proposed to be a biological marker for the properties of monoamine systems, with low activity being associated with vulnerability for high scores on personality traits such as sensation seeking, monotony avoidance, and impulsiveness, as well as for vulnerability for alcoholism. In the present study, platelet MAO-B activity was analysed in 78 rhesus macaques, and its relation to voluntary alcohol intake and behaviours after intravenous alcohol administration was observed. Monkeys with low platelet MAO-B activity had low levels of 5-hydroxyindole acetic acid in cerebrospinal fluid and showed excessive aggression after alcohol administration. A novel finding was that animals with low platelet MAO-B activity showed less intoxication following alcohol administration. As we have shown previously, they also voluntarily consumed more alcohol. We here replicate results from studies on both humans and non-human primates, showing the utility of platelet MAO as a marker for risk behaviours and alcohol abuse. Furthermore, we link platelet MAO activity to alcohol sensitivity.

Abstract
Early environment is a known determinant for individual differences in vulnerability for adult psychopathology, e.g., ethanol addiction. One underlying mechanism could be dysfunction in serotonergic neurotransmission. This study focused on the methodological considerations regarding an animal model for studying effects of early environment, maternal separation (MS), using two different paradigms. Age- and sex-specific effects on brain stem 5-hydroxytryptamine (5-HT) transporter and receptors were examined. Male and female rat pups were assigned to either litter-wise MS for 15 or 360 min (MS15l or MS360l) or individual MS for 15 or 360 min (MS15i or MS360i) daily during postnatal days 1-21. Normal animal facility reared rats were used as controls. Analyses were performed in young and adult rats. As compared to the other males, MS15l males had lower 5-HT(1A) and 5-HT(2C) receptor mRNA expression at both ages, lower 5-HT(2A) receptor mRNA when young and lower 5-HTT mRNA expression when adult. In contrast, adult MS15l females had higher 5-HT(2C) receptor mRNA expression than other female rats. The strong impact of MS15l on 5-HT-related genes was either transient or persistent depending on sex and fewer effects on gene expression were observed in females than in males. This study shows the importance of tactile contact for the consequences of short but not prolonged MS, as evidenced by major differences between MS15l and MS15i. The results suggest that MS15i is less suitable than MS15l to simulate a protective environment in studies of, for instance, ethanol addiction processes.

Abstract
AIMS To explore neuropsychological function in two differentiated patterns of platelet monoamine oxidase B (MAO B) activity in alcoholic patients. METHODS Neuropsychological examination and platelet MAO B activity extracted from blood were collected from 42 alcohol-dependent patients recruited in the alcoholism unit (NETER) of the Psychiatric Service of Santa Maria University Hospital. RESULTS Alcoholics presented significantly low levels of platelet MAO B activity, when compared with control subjects; platelet MAO B activity in alcoholics classified as "under average subgroup" showed significant lower scores in the Raven Progressive Matrix and higher scores in hostility dimension, when compared with platelet MAO B activity in "above average subgroup." CONCLUSIONS Results suggested platelet MAO B as a trait marker also to type I alcohol-dependent patients and the two observed associations between platelet MAO B activity with neurocognitive measures of executive functions (nonverbal reasoning) and psychopathological dimension such as hostility may support the notion about the effect of platelet MAO B activity in the further development of an impulsive cognitive style.

Abstract
The importance of an interaction between environment and biological factors for the expression for a particular behaviour is illustrated by results from a series of adolescents in which effects of platelet MAO activity and psychosocial environment on criminality was investigated. In a favourable environment platelet MAO-B activity was not associated with criminality, while a very strong association was found in adolescents from a bad psychosocial environment. Essentially similar findings were obtained when a MAO-A promoter polymorphism was analysed instead of platelet MAO-B activity. In boys, presence of the low functioning allele seemed to be protective against criminal activity in combination with a good environment, while it predisposed for criminality in a bad psycho-social environment. In girls, instead, homozygosity for the high activity MAO-A allele interacted with environment to predict criminality. Possible mechanisms underlying the role of monoamine oxidases for behaviour are discussed.

Abstract
We hypothesized that women with Turner syndrome (45,X) with a single X-chromosome inherited from their mother may show mentalizing deficits compared to women of normal karyotype with two X-chromosomes (46,X). Simple geometrical animation events (two triangles moving with apparent intention in relation to each other) which usually elicit mental-state descriptions in normally developing people, did not do so to the same extent in women with Turner syndrome. We then investigated the potential role in this deficit played by monoamine oxidase B enzymatic activity. MAO-B activity reflects central serotonergic activity, and by implication the functional integrity of neural circuits implicated in mentalizing. Platelet MAO-B was substantially reduced in Turner syndrome. However, contrary to prediction, in this (relatively small) sample there was no association between MAO-B enzymatic activity and mentalizing skills in participants with and without Turner syndrome.
