Various studies contributed to discover novel mechanisms of central arginine vasopressin (AVP) system responsible for the behaviour albeit endogenous vasopressin activation. We established a novel transgenic rat line which expresses both human muscarinic acetylcholine receptors (hM3Dq), of which ligand is clozapine-N-oxide (CNO), and mCherry fluorescence specifically in AVP neurons. The mCherry neurons that indicate the expression of the hM3Dq gene were observed in the suprachiasmatic (SCN), supraoptic (SON), and paraventricular nuclei (PVN)...

OBJECTIVE: Aberrant neutrophil extracellular trap (NET) formation has been implicated as a mechanism to induce auto-reactivity in at-risk individuals. The study objective was to assess whether medications implicated in cases of drug-induced autoimmunity (hydralazine and procainamide) and medications less commonly associated with drug-induced autoimmunity (minocycline and clozapine) induce NET formation and/or prevent NET degradation. METHODS: Human neutrophils were incubated with the drugs of interest and resultant NET formation was quantified by fluorescent microscopy...

While some second-generation antipsychotics have shown efficacy on patients with borderline personality disorder (BPD), limited data exist regarding the effect of clozapine. Thus, we aimed to investigate the effects of clozapine on naturalistic outcomes in BPD patients with a 2-year mirror-image model. Among 25,916 patients with BPD, 1,107 redeemed ≥ 1 clozapine prescription. Of these, 18,188 were "specific" BPD patients, and 102 redeemed ≥ 1 clozapine prescription. During a mean observation period of 598...

REVIEW
X-F Huang, K Weston-Green, Y Yu
Second generation antipsychotics (SGAs), notably atypical antipsychotics including olanzapine, clozapine and risperidone, can cause weight gain and obesity side effects. Antagonism of serotonin 2c receptors (5-HT2cR) and activation of ghrelin receptor type 1a (GHSR1a) signalling have been identified as a main cause of SGA induced obesity. Here we review the pivotal regulatory role of the 5-HT2cR in ghrelin-mediated appetite signalling. The 5-HT2cR dimerizes with GHSR1a to inhibit orexigenic signalling, while 5-HT2cR antagonism reduces dimerization and increases GHSR1a-induced food intake...

WHAT IS KNOWN AND OBJECTIVE: Hypertension, a major risk factor for adverse cardiovascular events, such as stroke and myocardial infarction, affects 80 million American adults. The aetiology of hypertension is multifaceted and difficult to identify. Dopamine receptors, especially those in the kidneys, play a role in blood pressure regulation, and alterations in their function can cause hypertension. The objective of this review was to investigate the association between the use of dopamine antagonists with hypertension focusing especially on second-generation antipsychotics, like clozapine that is D4 receptor antagonist...

OBJECTIVE: The risk of gastrointestinal hypomotility (GIHM) with the use of antipsychotic medications in patients with schizophrenia remains inadequately recognized. The aim of this study was to explore the incidence of GIHM and its risks in patients with schizophrenia treated with antipsychotics. METHODS: We conducted a retrospective cohort study using the National Health Insurance Research Database. We identified adult (≥ 20years of age) patients with a first-time diagnosis of schizophrenia or schizoaffective disorder in the Registry for Catastrophic Illness Patients during the period from 2001 to 2011...

OBJECTIVE: Glucagon-like peptides are co-released from enteroendocrine L cells in the gut and preproglucagon (PPG) neurons in the brainstem. PPG-derived GLP-1/2 are probably key neuroendocrine signals for the control of energy balance and glucose homeostasis. The objective of this study was to determine whether activation of PPG neurons per se modulates glucose homeostasis and insulin sensitivity in vivo. METHODS: We generated glucagon (Gcg) promoter-driven Cre transgenic mice and injected excitatory hM3Dq-mCherry AAV into their brainstem NTS...

We performed a systematic review and Bayesian network meta-analysis to determine atypical antipsychotics that are effective and safe for the treatment of psychosis in Parkinson's disease (PD). We conducted a comprehensive literature search using PubMed/MEDLINE, Cochrane Library, and Japana Centra Revuo Medicina (Ichu-shi Web). We used randomized controlled trials evaluating the utility of atypical antipsychotics for the treatment of psychosis in PD using the Brief Psychiatric Rating Scale (BPRS) and the Unified PD rating Scale parts III (UPDRS-III) as the endpoints...

Clozapine is a second-generation antipsychotic typically reserved for refractory psychotic disorders due to its high-risk side effect profile to include agranulocytosis, with its attendant need for regular blood draws. While reports of extrapyramidal symptoms (EPS), including acute dystonic reactions, are exceedingly rare, we present the case of a 44-year-old male with a long-standing history of treatment-resistant schizoaffective disorder and no history of EPS who experienced an acute buccal dystonic reaction in the setting of clozapine initiation and discontinuation of depot and oral risperidone...

Clozapine, a representative atypical antipsychotic, has superior efficacy compared to other antipsychotic agents and is used for the treatment of severe psychotic disorders. Therefore, studies on its mechanisms of action are important for understanding the mechanisms of therapeutic approaches to psychosis. Adenosine monophosphate-activated protein kinase (AMPK) is a serine-threonine kinase that plays a major role in maintaining metabolic homeostasis. Unc-51-like kinase 1 (ULK1) and Beclin1 are downstream substrates of AMPK and activate the autophagic process...

Ai-Jun Li, Qing Wang, Sue Ritter
Catecholamine (CA) neurons in the ventrolateral medulla (VLM) contribute importantly to glucoregulation during glucose deficit. However, it is not known which CA neurons elicit different glucoregulatory responses or whether selective activation of CA neurons is sufficient to elicit these responses. Therefore, to selectively activate CA subpopulations, we injected male or female Th-Cre+ transgenic rats with the Cre-dependent DREADD construct, AAV2-DIO-hSyn-hM3D(Gq)-mCherry, at one of 4 rostrocaudal levels of the VLM: rostral C1 (C1r), middle C1 (C1m), the area of A1 and C1 overlap (A1/C1) or A1...

INTRODUCTION: Many psychopharmacologic agents are used as primary or adjunct agents in pain management. Atypical antipsychotics (AAs) have also been used as adjuncts in pain management regimens in a variety of manners; however, their efficacy in this capacity is unclear. METHODS: A systematic review of all studies examining AA use for pain was conducted. Three literature databases were utilized to search for word combinations of "pain" and a variety of commonly-prescribed AAs (olanzapine, quetiapine, risperidone, aripiprazole, ziprasidone, clozapine, paliperidone, iloperidone, lurasidone)...

BACKGROUND: Severe and persistent mental illnesses, such as schizophrenia and bipolar disorder, are associated with increased risk of obesity compared to the general population. While the association of lurasidone and lower risk of weight gain has been established in short and longer-term clinical trial settings, information about lurasidone's association with weight gain in usual clinical care is limited. This analysis of usual clinical care evaluated weight changes associated with lurasidone treatment in patients with schizophrenia or bipolar disorder...

OBJECTIVE: Treatment resistance is a challenge for the management of schizophrenia. It is not always clear whether inadequate response is secondary to medication ineffectiveness, as opposed to medication underexposure due to non-adherence or pharmacokinetic factors. We investigated the prevalence of subtherapeutic antipsychotic plasma levels in patients identified as treatment-resistant by their treating clinician. METHOD: Between January 2012 and April 2017, antipsychotic plasma levels were measured in 99 individuals provisionally diagnosed with treatment-resistant schizophrenia by their treating clinicians, but not prescribed clozapine...
