Enhanced axonal Neuregulin-1 type-III signaling ameliorates neurophysiology and hypomyelination in a Charcot-Marie-Tooth type 1B mouse model.

Hum Mol Genet 2018 Nov 27. Epub 2018 Nov 27.

DIBIT, Divisions of Genetics and Cell Biology.

Charcot-Marie-Tooth neuropathies (CMTs) are a group of genetic disorders that affect the peripheral nervous system (PNS) with heterogeneous pathogenesis and no available treatment. Axonal Neuregulin 1 type III (Nrg1TIII) drives peripheral nerve myelination by activating downstream signaling pathways such as PI3K/Akt and MAPK/Erk that converge on master transcriptional regulators of myelin genes, such as Krox20. We reasoned that modulating Nrg1TIII activity may constitute a general therapeutic strategy to treat CMTs that are characterized by reduced levels of myelination. Read More

Anthracycline and taxane-based chemotherapy versus docetaxel and cyclophosphamide in the adjuvant treatment of HER2-negative breast cancer patients: a systematic review and meta-analysis of randomized controlled trials.

Breast Cancer Res Treat 2018 Nov 21. Epub 2018 Nov 21.

Department of Medical Oncology, Institut Jules Bordet and Université Libre de Bruxelles (ULB), Boulevard de Waterloo 121, 1000, Brussels, Belgium.

Purpose: Standard adjuvant chemotherapy for HER2-negative breast cancer consists generally in an anthracycline and taxane-based regimen (A+T). The TC (docetaxel and cyclophosphamide) regimen arises as a potential alternative, although individual randomized controlled trials (RCTs) could not demonstrate the non-inferiority of TC over A+T. This is a systematic review and meta-analysis of RCTs comparing 6 cycles of TC versus sequential A+T in the adjuvant treatment of HER2-negative breast cancer. Read More

The conceptual introduction of the "demyelinating Schwann cell" in peripheral demyelinating neuropathies.

Glia 2018 Oct 30. Epub 2018 Oct 30.

INSERM U1051, Institut des Neurosciences de Montpellier (INM), Université de Montpellier, Montpellier, France.

Myelinating Schwann cells undergo irreversible demyelination in many demyelinating neuropathies that show complete demyelination of the internode. Dedifferentiation, reprogramming, and myelin clearance processes-which are specifically discussed in this article-appear to be shared by various demyelinating peripheral conditions, such as Wallerian degeneration, immune-mediated, and toxic demyelinating diseases. We propose to introduce the concept of the "demyelinating Schwann cell (DSC)" as a novel cell phenotype, which has specific properties required for myelin sheath clearance. Read More

Carboplatin/Paclitaxel Induction in Ovarian Cancer: The Finer Points.

Oncology (Williston Park) 2018 08;32(8):418-20, 422-4

The carboplatin/paclitaxel doublet remains the chemotherapy backbone for the initial treatment of ovarian cancer. This two-drug regimen, with carboplatin dosed using the Calvert formula, yielded convincing noninferior outcomes when compared with the prior, more toxic, regimen of cisplatin/paclitaxel. Carboplatin's dose-limiting toxicity is thrombocytopenia; however, when this drug is properly dosed and combined with paclitaxel, the doublet's cycle 1 dose in chemotherapy-naive women is generally safe.

The Antidiabetic Drug Liraglutide Minimizes the Non-Cholinergic Neurotoxicity of the Pesticide Mipafox in SH-SY5Y Cells.

Neurotox Res 2018 Aug 7. Epub 2018 Aug 7.

Departamento de Análises Clínicas, Toxicológicas e Bromatológicas, Faculdade de Ciências Farmacêuticas de Ribeirão Preto-FCFRP, Universidade de São Paulo, USP, Avenida do Café s/n, Ribeirão Preto, SP, 14040-903, Brazil.

Organophosphorus (OPs) compounds have been widely used in agriculture, industry, and household, and the neurotoxicity induced by them is still a cause of concern. The main toxic mechanism of OPs is the inhibition of acetylcholinesterase (AChE); however, the delayed neuropathy induced by OPs (OPIDN) is mediated by other mechanisms such as the irreversible inhibition of 70% of NTE activity (neuropathy target esterase) that leads to axonal degeneration. Liraglutide is a long-lasting GLP-1 analog clinically used as antidiabetic. Read More

Sustained Expression of Negative Regulators of Myelination Protects Schwann Cells from Dysmyelination in a Charcot-Marie-Tooth 1B Mouse Model.

J Neurosci 2018 May 2;38(18):4275-4287. Epub 2018 Apr 2.

Division of Genetics and Cell Biology, San Raffaele Scientific Institute, DIBIT, Milan, Italy 20132,

Schwann cell differentiation and myelination in the PNS are the result of fine-tuning of positive and negative transcriptional regulators. As myelination starts, negative regulators are downregulated, whereas positive ones are upregulated. Fully differentiated Schwann cells maintain an extraordinary plasticity and can transdifferentiate into "repair" Schwann cells after nerve injury. Read More

Assessment of metal concentrations in the SOD1 mouse model of amyotrophic lateral sclerosis and its potential role in muscular denervation, with particular focus on muscle tissue.

Mol Cell Neurosci 2018 04 7;88:319-329. Epub 2018 Mar 7.

Wollongong Isotope Geochronology Laboratory and School of Earth and Environmental Sciences, University of Wollongong, Australia.

Background: Amyotrophic lateral sclerosis (ALS) is among the most common of the motor neuron diseases, and arguably the most devastating. During the course of this fatal neurodegenerative disorder, motor neurons undergo progressive degeneration. The currently best-understood animal models of ALS are based on the over-expression of mutant isoforms of Cu/Zn superoxide dismutase 1 (SOD1); these indicate that there is a perturbation in metal homeostasis with disease progression.

Plexin-Semaphorin Signaling Modifies Neuromuscular Defects in a Model of Peripheral Neuropathy.

Front Mol Neurosci 2018 22;11:55. Epub 2018 Feb 22.

MRC Functional Genomics Unit, Department of Physiology, Anatomy and Genetics, University of Oxford, Oxford, United Kingdom.

Dominant mutations in , encoding the ubiquitous enzyme glycyl-tRNA synthetase (GlyRS), cause peripheral nerve degeneration and Charcot-Marie-Tooth disease type 2D (CMT2D). This genetic disorder exemplifies a recurring paradigm in neurodegeneration, in which mutations in essential genes cause selective degeneration of the nervous system. Recent evidence suggests that the mechanism underlying CMT2D involves extracellular neomorphic binding of mutant GlyRS to neuronally-expressed proteins. Read More

Mitochondrial damage and "plugging" of transport selectively in myelinated, small-diameter axons are major early events in peripheral neuroinflammation.

J Neuroinflammation 2018 Feb 27;15(1):61. Epub 2018 Feb 27.

Department of Neuroinflammation, Institute of Neurology (Queen Square), University College London, 1 Wakefield Street, London, WC1N 1PJ, UK.

Background: Small-diameter, myelinated axons are selectively susceptible to dysfunction in several inflammatory PNS and CNS diseases, resulting in pain and degeneration, but the mechanism is not known.

Methods: We used in vivo confocal microscopy to compare the effects of inflammation in experimental autoimmune neuritis (EAN), a model of Guillain-Barré syndrome (GBS), on mitochondrial function and transport in large- and small-diameter axons. We have compared mitochondrial function and transport in vivo in (i) healthy axons, (ii) axons affected by experimental autoimmune neuritis, and (iii) axons in which mitochondria were focally damaged by laser induced photo-toxicity.

Polyneuropathies.

Dtsch Arztebl Int 2018 Feb;115(6):83-90

Department of Neurology, University Hospital Würzburg; DRK Pain Center Mainz; Department of Sleep Medicine and Neuromuscular Disorders, Münster University; University Orthopedic Clinic Erlangen; Department of Neurology, University Hospital Mainz; Friedrich-Baur Institute, Department of Neurology, Ludwig-Maximilians-Universität Munich.

Background: Polyneuropathies (peripheral neuropathies) are the most common type of disorder of the peripheral nervous system in adults, and specifically in the elderly, with an estimated prevalence of 5-8%, depending on age. The options for treatment depend on the cause, which should therefore be identified as precisely as possible by an appropriate diagnostic evaluation.

Methods: This review is based on the current guidelines and on large-scale cohort studies and randomized, controlled trials published from 2000 to 2017, with an emphasis on non-hereditary types of polyneuropathy, that were retrieved by a selective search in PubMed. Read More
