  1. 1. Factors influencing transferrin receptor-mediated brain delivery : Evaluating preclinical antibody-based proteins for PET imaging in Alzheimer’s disease

    Author : Rebecca Faresjö Melander; Stina Syvänen; Dag Sehlin; Robert Thorne; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain delivery; bispecific antibody; transferrin receptor; Alzheimer s Disease; amyloid-beta; aging; single domain antibody; PET; Biofarmaci; Biopharmaceutics; Neurology; Neurologi; Molekylär medicin; Molecular Medicine; Biofarmaci; Biopharmaceutics;

    Abstract : Antibody-based proteins targeting amyloid-beta (Aβ) could be used as radioligands in positron emission tomography (PET) to study Alzheimer’s disease (AD) pathology in the living brain. The prospective advantages of antibody-based PET are to detect pathology earlier, with higher sensitivity, and to evaluate treatment effects of emerging immunotherapies against Aβ. READ MORE

  2. 2. Aβ Conformation Dependent Antibodies and Alzheimer's Disease

    Author : Dag Sehlin; Lars Lannfelt; Frida Ekholm Pettersson; David Teplow; Uppsala universitet; []
    Keywords : Alzheimer s disease; amyloid-beta; protofibrils; conformation; monoclonal antibody; ELISA; MEDICINE; MEDICIN; Geriatrics; Geriatrik;

    Abstract : Soluble intermediates of the amyloid-β (Aβ) aggregation process are suggested to play a central role in the pathogenesis of Alzheimer’s disease (AD) by causing synaptic dysfunction and neuronal loss. In this thesis, soluble Aβ aggregates have been studied with a particular focus on the Aβ protofibril, which has served as the antigen for developing conformation dependent monoclonal antibodies.

  3. 3. Preclinical PET imaging of Alzheimer's disease progression

    Author : Xiaotian T. Fang; Stina Syvänen; Dag Sehlin; Lars Lannfelt; Merja Haaparanta-Solin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer s disease; transgenic mice; PET; antibody-based tracer; mGluR5; ABP688; di-scFv; amyloid-β;

    Abstract : Amyloid PET imaging with [11C]PIB enabled detection of Aβ for the first time in vivo. However, [11C]PIB is a small molecule that binds only the insoluble Aβ plaque. Rather, the soluble Aβ aggregates are considered the cause of Alzheimer’s disease (AD). READ MORE

  4. 4. Preclinical PET imaging and therapy of Alzheimer's disease

    Author : Silvio R. Meier; Stina Syvänen; Dag Sehlin; Greta Hultqvist; Matthias Brendel; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. Cellular responses to amyloid-beta protofibrils : Focus on astrocytes, extracellular vesicles and antibody treatment

    Author : Elisabeth Nikitidou; Anna Erlandsson; Martin Ingelsson; Gunnar K. Gouras; Uppsala universitet; []
    Keywords : Alzheimer’s disease; Amyloid-beta; Protofibrils; Astrocytes; Extracellular vesicles; Antibody; Neurons; Degradation; Medicinsk vetenskap; Medical Science;

    Abstract : Knowledge about the cellular mechanisms behind the initiation and propagation of Alzheimer’s disease (AD) is limited. Decades of research have focused on neuronal abnormalities in AD, but recently more attention has been given to the glial cells. READ MORE
