  • A Human Stem Cell-Derived Test System for Agents Modifying Neuronal N
    Archives of Toxicology (2021) 95:1703–1722 https://doi.org/10.1007/s00204-021-03024-0 IN VITRO SYSTEMS A human stem cell‑derived test system for agents modifying neuronal 2+ N‑methyl‑D‑aspartate‑type glutamate receptor Ca ‑signalling Stefanie Klima1,2 · Markus Brüll1 · Anna‑Sophie Spreng1,3 · Ilinca Suciu1,3 · Tjalda Falt1 · Jens C. Schwamborn4 · Tanja Waldmann1 · Christiaan Karreman1 · Marcel Leist1,5 Received: 28 October 2020 / Accepted: 4 March 2021 / Published online: 13 March 2021 © The Author(s) 2021 Abstract Methods to assess neuronal receptor functions are needed in toxicology and for drug development. Human-based test systems that allow studies on glutamate signalling are still scarce. To address this issue, we developed and characterized pluripotent stem cell (PSC)-based neural cultures capable of forming a functional network. Starting from a stably proliferating neu- roepithelial stem cell (NESC) population, we generate “mixed cortical cultures” (MCC) within 24 days. Characterization by immunocytochemistry, gene expression profling and functional tests (multi-electrode arrays) showed that MCC contain various functional neurotransmitter receptors, and in particular, the N-methyl-D-aspartate subtype of ionotropic glutamate receptors (NMDA-R). As this important receptor is found neither on conventional neural cell lines nor on most stem cell- derived neurons, we focused here on the characterization of rapid glutamate-triggered Ca2+ signalling. Changes of the intra- 2+ cellular free calcium ion concentration ([Ca ]i) were measured by fuorescent imaging as the main endpoint, and a method to evaluate and quantify signals in hundreds of cells at the same time was developed. We observed responses to glutamate in the low µM range.

  • 5-HT Receptor Agonist Befiradol Reduces Fentanyl-Induced
    5-HT1A Receptor Agonist Befiradol Reduces Fentanyl-induced Respiratory Depression, Analgesia, and Sedation in Rats Jun Ren, Ph.D., Xiuqing Ding, B.Sc., John J. Greer, Ph.D. ABSTRACT Background: There is an unmet clinical need to develop a pharmacological therapy to counter opioid-induced respiratory depression without interfering with analgesia or behavior. Several studies have demonstrated that 5-HT1A receptor agonists alleviate opioid-induced respiratory depression in rodent models. However, there are conflicting reports regarding their effects on analgesia due in part to varied agonist receptor selectivity and presence of anesthesia. Therefore the authors performed a Downloaded from http://pubs.asahq.org/anesthesiology/article-pdf/122/2/424/267207/20150200_0-00031.pdf by guest on 27 September 2021 study in rats with befiradol (F13640 and NLX-112), a highly selective 5-HT1A receptor agonist without anesthesia. Methods: Respiratory neural discharge was measured using in vitro preparations. Plethysmographic recording, nociception testing, and righting reflex were used to examine respiratory ventilation, analgesia, and sedation, respectively. Results: Befiradol (0.2 mg/kg, n = 6) reduced fentanyl-induced respiratory depression (53.7 ± 5.7% of control minute ven- tilation 4 min after befiradol vs. saline 18.7 ± 2.2% of control, n = 9; P < 0.001), duration of analgesia (90.4 ± 11.6 min vs. saline 130.5 ± 7.8 min; P = 0.011), duration of sedation (39.8 ± 4 min vs. saline 58 ± 4.4 min; P = 0.013); and induced baseline hyperventilation, hyperalgesia, and “behavioral syndrome” in nonsedated rats. Further, the befiradol-induced alleviation of opioid-induced respiratory depression involves sites or mechanisms not functioning in vitro brainstem–spinal cord and medul- lary slice preparations.

  • Therapy Focus – J&J Confirms Hope for New Mechanism in Depression
    May 09, 2018 Therapy focus – J&J confirms hope for new mechanism in depression Amy Brown The first look at late-stage data on Johnson & Johnson’s hotly-tipped novel antidepressant esketamine came at a medical conference last weekend, and the results were not quite as strong as many were hoping to see. Encouraging signals could be certainly be found, however, and J&J seems undeterred from trying to seek regulatory approval. Others pursing NMDA modulation in depression are also likely to draw comfort in the results, which provide the first phase III validation of this mechanism, and a clear bar to beat (see table below). Hopes for esketamine and other products like it lie in their similarity to ketamine, which at low doses displays antidepressant effects that kick in very quickly. Traditional antidepressants which act via the serotonergic system – selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) – can take weeks to have an effect; a large proportion of patients fail to respond at all. Hence the need for both faster acting agents – for example in suicidal patients – and novel mechanisms to treat those who need different options. A new target NMDA receptor modulation is a novel mechanism in depression. Over the last decade researchers have become increasingly convinced that dysregulation of glutamate, a neurotransmitter which signals through NMDA, plays an important role in the condition. This system is already known to be a factor in cognitive function and neurodegeneration and Namenda, the NMDA antagonist mematine, has been available as a treatment for Alzheimer’s dementia for several years.

    Cigna National Formulary Coverage Policy Prior Authorization Cushing’s – Isturisa® (osilodrostat tablets) Table of Contents Product Identifier(s) National Formulary Medical Necessity ................ 1 64705 Conditions Not Covered....................................... 2 Background .......................................................... 2 References .......................................................... 3 Revision History ................................................... 3 INSTRUCTIONS FOR USE The following Coverage Policy applies to health benefit plans administered by Cigna Companies. Certain Cigna Companies and/or lines of business only provide utilization review services to clients and do not make coverage determinations. References to standard benefit plan language and coverage determinations do not apply to those clients. Coverage Policies are intended to provide guidance in interpreting certain standard benefit plans administered by Cigna Companies. Please note, the terms of a customer’s particular benefit plan document [Group Service Agreement, Evidence of Coverage, Certificate of Coverage, Summary Plan Description (SPD) or similar plan document] may differ significantly from the standard benefit plans upon which these Coverage Policies are based. For example, a customer’s benefit plan document may contain a specific exclusion related to a topic addressed in a Coverage Policy. In the event of a conflict, a customer’s benefit plan document always supersedes the information in the Coverage Policies. In the absence of a controlling federal or state coverage mandate, benefits are ultimately determined by the terms of the applicable benefit plan document. Coverage determinations in each specific instance require consideration of 1) the terms of the applicable benefit plan document in effect on the date of service; 2) any applicable laws/regulations; 3) any relevant collateral source materials including Coverage Policies and; 4) the specific facts of the particular situation.

The goal of treatment is to rapidly control cortisol excess and achieve long-term remission, to reverse the clinical features and reduce long-term complications associated with increased mortality. While pituitary surgery remains first line therapy, pituitary radiotherapy and bilateral adrenalectomy have traditionally been seen as second-line therapies for persistent hypercortisolism. Medical therapy is now recognized to play a key role in the control of cortisol excess. In this review, all currently available medical therapies are summarized, and novel medical therapies in phase 3 clinical trials, such as osilodrostat and levoketoconazole are discussed, with an emphasis on indications, efficacy and safety. Emerging data suggests increased efficacy and better tolerability with these novel therapies and combination treatment strategies, and potentially increases the therapeutic options for treatment of CD. New insights into the pathophysiology of CD are highlighted, along with potential therapeutic applications. Future treatments on the horizon such as R-roscovitine, retinoic acid, epidermal growth factor receptor inhibitors and somatostatin-dopamine chimeric compounds are also described, with a focus on potential
