One protein, many faces: characterization of tau protein oligomers involved in Alzheimer’s disease and other tauopathies
PhD defence. Wednesday, 19 April 2017. Angela de Poli
Neurodegenerative conditions, such as Alzheimer’s disease and progressive supranuclear palsy, are associated with the accumulation of aggregates made of a protein called tau. The small tau oligomeric species appearing at early stages in these pathologies are considered to play the main cytotoxic role in the brain. For this reason, they represent a good target for the development of therapies to slower or even reverse the disease course. However, the heterogeneous and transient nature of the oligomers makes their study rather challenging. During her PhD studies, Angela de Poli prepared homogeneous tau oligomers in vitro and extensively studied their physicochemical properties through different biochemical and biophysical techniques. She then tested the aggregates in cell cultures and investigated their ability to act as “seeds” able to spread the pathology.
The new research findings expand the knowledge on the properties of tau oligomers and on their pathological role in neuronal degeneration. The oligomers coming from this study will hopefully be used as biomarkers for the development of viable therapies to cure different neurodegenerative conditions.
Angela de Poli conducted part of her PhD studies at Crossbeta Biosciences, Utrecht, the Netherlands. The PhD degree was completed at the Interdisciplinary Nanoscience Center (iNANO), Science and Technology, Aarhus University.
This résumé was prepared by the PhD student.
