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

2. Harnessing the molecular Trojan horse : Evaluating properties of preclinical Aβ immunoPET radioligands for optimized brain delivery via the transferrin receptor
Abstract : With high specificity and selectivity to targets, antibodies are prime candidates for positron emission tomography (PET) radioligands. They do not passively cross the blood-brain barrier which has hindered their development for imaging intrabrain targets, like amyloid-β (Aβ) in Alzheimer’s disease. READ MORE

3. Preclinical PET imaging of Alzheimer's disease progression
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. Factors influencing transferrin receptor-mediated brain delivery : Evaluating preclinical antibody-based proteins for PET imaging in Alzheimer’s disease
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

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