2. 1. Regulation of Injury Induced Schwann Cell Proliferation Schwann Cell Proliferation

   Author : Åsa Fex Svenningsen; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; estrogen; signal transduction; insulin like growth-factors; Schwann cell; peripheral; nerve regeneration; Djurfysiologi; Animal physiology; progesterone;

   Abstract : The purpose of this study was to investigate injury induced proliferation of Schwann cells with emphasis of the effects of the insulin-like growth factors (IGF-I and IGF-II) and the sex hormones progesterone and estrogen. Proliferation, measured as [3H] thymidine incorporation, was studied in cultured segments of the rat sciatic nerve or through the use of the thymidine analogue bromo- deoxy-uridine (BrdU) in combination with immunocytochemistry.

4. 2. Cell models for evaluation of adult and developmental neurotoxicity : Focus on acrylamide

   Author : Kristina Attoff; Anna Forsby; Åsa Fex-Svenningsen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

   Abstract : This thesis is aimed at summarizing some of the alternative in vitro methods and models that have been used to study both adult and developmental neurotoxicity (DNT), and also to pinpoint some of the important aspects of using alternative in vitro methods. The aim of the papers included in this thesis was to challenge the hypothesis that neurotoxicity and DNT of chemicals can be studied using robust endpoints for proliferation and neural differentiation, such as neurite outgrowth, mRNA expression and protein expression, in two different cell lines.

5. 3. Neuron-glial Interaction in the Developing Peripheral Nervous System

   Author : Mikael Corell; Åsa Fex Svenningsen; Klas Kullander; Helgi Schöith; Heape Anthony; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Schwann cell; nonmyelinating Schwann cell; myelinating Schwann cell; development; proliferation; differentiation; myelin; neural stem cell; central nervous system; peripheral nervous system; enteric nervous system; N-cadherin; GABA; GAD; GABA B receptor; baclofen; CGP55485; Neuroscience; Neurovetenskap; Neuroscience; Neurovetenskap;

   Abstract : The nervous system, including the brain, is the most sophisticated organ in the mammalian body. In such a complex network, neuron-glial interaction is essential and controls most developmental processes, such as stem cell fate determination, migration, differentiation, synapse formation, ensheathment and myelination.

6. 4. Neuroblastoma SH-SY5Y and neural progenitor C17.2 cell lines as models for neurotoxicological studies​

   Author : Jessica Lundqvist; Anna Forsby; Åsa Fex Svenningsen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SH-SY5Y; C17.2; in vitro neurotoxicity; cell culture conditions; biomarkers; in vitro developmental neurotoxicity; whole genome microarray; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

   Abstract : We are surrounded by chemicals, thus understanding how exposure to these chemicals affect us during our life is of great social importance. In order to predict human acute toxicity of chemicals, cosmetics or drugs, development of novel in vitro test strategies is required. READ MORE

7. 5. Autosomal Dominant Leukodystrophy with Autonomic Symptoms and Rippling Muscle Disease : Translational Studies of Two Neurogenetic Diseases

   Author : Jimmy Sundblom; Anja Smits; Raili Raininko; Niklas Dahl; Klas Kullander; Åsa Fex-Svenningsen; Marianne de Visser; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inborn genetic diseases; Leukoencephalopathies; Lamin type B; Muscular disease; Caveolin 3; Neurology; Neurologi;

   Abstract : There is a large variety of diseases caused by single-gene mutations. Although most of these conditions are rare, together they impose a significant burden to the population. READ MORE
