  1. 1. Generation of Dopaminergic Neurons from Human Embryonic Stem Cells

    Author : Tandis Vazin; Joakim Lundeberg; Ernest Arenas; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human; dopaminergic; embryonic stem cells; differentiation; stromal cells; PA6 cells; dopamine; neurons; Neuroscience; Neurovetenskap; Neurobiology; Neurobiologi; Molecular neurobiology; Molekylär neurobiologi;

    Abstract : Since the first successful derivation of human embryonic stem cells (hESC), rapid progress has been attained in the development of strategies in differentiation of these cells into various neural lineages, with the fundamental objective of using these cells for replacement and repair of damaged neuronal circuits in the central nervous system (CNS). Of particular interest are midbrain dopaminergic (mDA) neurons, which play a central role in regulation of voluntary movement. READ MORE

  2. 2. Physiological Studies of Native and Stem Cell-Derived Islets

    Author : Daniel Norman; Per-Ola Carlsson; Daniel Espes; Helge Ræder; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Irisin; CART; Islet blood flow; Islets of Langerhans; Stem cell-derived islets; Fysiologi; Physiology; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : In type 1 and type 2 diabetes, the β-cells of the islets of Langerhans are either destroyed by the immune system or stressed due to peripheral insulin resistance. To improve the life of patients with these diseases, new treatments are needed. READ MORE

  3. 3. Brain Stem Involvement in Immune and Aversive Challenge

    Author : Jakob Paues; Anders Blomqvist; Finn Hallböök; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lipopolysaccharide; Lithium Chloride; anorexia; aversion; parabrachial; brain stem; melanocortin; CGRP; enkephalin; Neurobiology; Neurobiologi;

    Abstract : Activation of the immune system by e.g. bacteria induces the acute-phase-response and sickness behaviour. The latter encompasses among other things fever, lethargy, anorexia and hyperalgesia. READ MORE

  4. 4. Role of GABA and GABAA Channels in T lymphocytes and Stem cells

    Author : Suresh Kumar Mendu; Bryndis Birnir; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : GABA (gamma-aminobutyric acid) is best known for its physiological function in the central nervous system.  In the brain GABA is the main inhibitory neurotransmitter where it decreases excitability of neurons and neuronal networks. READ MORE

  5. 5. Ethanol-mediated effects on astroglial cells in primary culture. With a focus on acute changes in intracellular Ca2+, cell volume, actin filaments, and gap junction coupling

    Author : Louise Adermark; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; astrocyte; BaCl2; cell swelling; fura-2; furosemide; ouabain; scrape loading; volume estimation;

    Abstract : The astroglial cells are abundant in the central nervous system (CNS), where they control and regulate the homeostasis of the extracellular milieu. A change in astroglial cell volume, mediated through activation of neuroactive substances or changes in osmolarity, leads to changes in the size and geometry of the extracellular space volume, which could affect the diffusion and concentration of neuroactive substances.
