  1. 1. Advanced Fluorescence Microscopy to Study Plasma Membrane Protein Dynamics

    Författare :Joachim Piguet; Horst Vogel; Ruud Hovius; Jerker Widengren; Antoine Triller; Switzerland Ecole Polytechnique Fédérale de Lausanne (EPFL); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluorescence; microscopy; plasma membrane; membrane proteins; membrane proteins diffusion; single-molecule imaging; single-molecule tracking; pentameric ligand-gated ion channels; nicotinic acetylcholine receptor; serotonin receptor; synapse; neuromuscular junction; post-synaptic scaffold; rapsyn; myopathies; fluorescent proteins; Förster resonance energy transfer; FRET imaging; protein-protein interactions; protein trafficking; photo-activatable proteins; Biological Physics; Biologisk fysik;

    Sammanfattning : Membrane protein dynamics is of great importance for living organisms. The precise localization of proteins composing a synapse on the membrane facing a nerve terminus is essential for proper functioning of the nervous system. In muscle fibers, the nicotinic acetylcholine is densely packed under the motor nerve termini. LÄS MER

  3. 2. Patch-clamp studies of the GABAA receptor using microfluidic methods

    Författare :Maria Millingen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ion channel; microfluidics; GABAA receptor;

    Sammanfattning : Ion channels are membrane proteins that passively transport ions. When activated, conformational changes within the protein lead to opening of a channel pore, and the flow of ions causes a change in the membrane potential. This is the fundamental process behind the generation and transduction of nerve impulses. LÄS MER

  4. 3. Amino acid transport and receptor binding properties in neuropsychiatric disorders using the fibroblast cell model

    Författare :Jessica Johansson; Nikolaos Venizelos; Lars Oreland; Örebro universitet; []
    Nyckelord :Fibroblasts; Bipolar disorder; ADHD; Tyrosine; Tryptophan; Alanine; Transport; mAChRs; Biomedicin; Biomedicine;

    Sammanfattning : Altered transport of the catecholamines and serotonin precursor amino acids tyrosine and tryptophan, might be one explanation for the dysfunctional neurotransmission implicated in the pathophysiology of bipolar disorder and Attention Deficit/Hyperactivity Disorder (ADHD). In previous studies, an altered amino acid transport has been found in schizophrenia and autism, when using the fibroblast cell model. LÄS MER

  5. 4. Pet imaging of two monoaminergic neurotransmitter systems in brain : studies of the norepinephrine transporter and dopamine D[2] receptor

    Författare :Nicholas Seneca; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Positron emission tomography (PET) has been widely used to study non-invasively function of the brain, pathophysiology of disease and aid in the development of new drugs. PET and selective radiolabeled molecules allow imaging of certain critical components of neurotransmission, such as pre-synaptic transporters and post-synaptic receptors in living brain. LÄS MER

  7. 5. The diagnosis and protection of the auditory peripheral system

    Författare :Mao Li Duan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cochlea; inner hair cell; outer hair cell; glutamate; post-synaptic receptor; auditory brainstem response; forward masking; noise trauma; hearing loss;

    Sammanfattning : The main focus of this thesis is on the diagnosis and prevention of peripheral hearing loss. An auditory evoked response measure (forward masking) was developed that specifically tests the function of the inner hair cells, independently of the outer hair cells. LÄS MER
