  1. 41. Preclinical PET imaging and therapy of Alzheimer's disease

    Författare :Silvio R. Meier; Stina Syvänen; Dag Sehlin; Greta Hultqvist; Matthias Brendel; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer s disease; amyloid-beta; positron emission tomography PET ; bispecific antibody; BACE-1; TREM2; GFAP; Molekylär medicin; Molecular Medicine; Neuroscience; Neurovetenskap;

    Sammanfattning : The main histopathological hallmarks of Alzheimer’s disease are extracellular amyloid-beta (Aβ) plaques and intracellular neurofibrillary tangles, containing tau protein. Because of misfolded and aggregated proteins, activated microglia and astroglia react with a neuroinflammatory response, which may contribute to disease progression and severity. LÄS MER

  3. 42. Stress steroids as accelerators of Alzheimer's disease. : Effects of chronically elevated levels of allopregnanolone in transgenic AD models

    Författare :Sara Bengtsson; Mingde Wang; Torbjörn Bäckström; Maja Johansson; Caroline Graff; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Allopregnanolone; Alzheimer s disease; beta-amyloid; synaptophysin; chronic stress; Morris water maze; obstetrik och gynekologi; Obstetrics and Gynaecology; medicinsk farmakologi; Medical Pharmacology; Neurology; neurologi; Geriatrics; geriatrik; medical behavioral science; medicinsk beteendevetenskap;

    Sammanfattning : Background Alzheimer’s disease (AD) and dementia are devastating con­ditions not only for the affected patients but also for their families.  The economical costs for the society are tremendous. LÄS MER

  4. 43. Mutational effects on protein structure and function

    Författare :Jonas Carlsson; Persson Bengt; Uwe Sauer; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mutation; prediction; phenotypes; homology model; virtual screening; molecular dynamics; amyloid; cancer; membrane protein; Bioinformatics; Bioinformatik;

    Sammanfattning : In this thesis several important proteins are investigated from a structural perspective. Some of the proteins are disease related while other have important but not completely characterised functions. LÄS MER

  5. 44. The choreography of protein vibrations : Improved methods of observing and simulating the infrared absorption of proteins

    Författare :Eeva-Liisa Karjalainen; Andreas Barth; Astrid Gräslund; Timothy A. Keiderling; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Infrared spectroscopy; FTIR; protein; atpase; amyloid; caged compound; amide I; transition dipole coupling; exciton theory; simulation; Molecular biophysics; Molekylär biofysik; Biophysics; biofysik;

    Sammanfattning : The work presented in this thesis has striven toward improving the capability to study proteins using infrared (IR) spectroscopy. This includes development of new and improved experimental and theoretical methods to selectively observe and simulate protein vibrations. LÄS MER

  7. 45. Developing a Porcine Model to Study the Glymphatic System

    Författare :Nicholas Bechet; Glia-Immune Interactions; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glymphatic system; cerebrospinal fluid; Porcine; in vivo imaging; amyloid beta; Alzheimer disease;

    Sammanfattning : The glymphatic system is a brain-wide solute clearance system that has developed in the brain to clear metabolic waste during sleep. This clearance is mediated by advective fluxes of cerebrospinal fluid (CSF) along perivascular spaces (PVS) and through the brain. LÄS MER
