Project description
Investigating mechanisms of Tau fibril disaggregation in real time
The extension of the human life span made age-related neurodegenerative diseases, including Alzheimer’s disease (AD) and other dementias, the second leading cause of death in high-income countries. The Tau amyloid aggregation in the brain closely correlates with cognitive impairment in AD and other dementias. Recent cell model studies showed that the ATPase complex of valosin-containing protein (VCP) can mediate the disaggregation of Tau fibrils. Funded by the Marie Skłodowska-Curie Actions programme, the Tau DG RT-imaging will utilise live cell fluorescence imaging and single-molecule tracking to investigate the mechanism of VCP regulation of Tau disaggregation in real time. The project aims to contribute to the development of new therapeutic strategies for tauopathies.
Objective
Age-dependent neurodegenerative diseases associated with protein aggregation represent one of the most important medical and socio-economic challenges of our time. With the extension of human life span, the prevalence of this group of diseases has markedly increased. Among them, Alzheimer’s diseases (AD) and other dementias have become the second leading cause of death in high-income countries. As a pathological hallmark, Tau amyloid aggregation in the brain has been determined to be closely related to the cognitive impairment in AD and related dementias. Despite major research efforts world-wide, the mechanism of Tau pathology and how its manifestation is prevented in healthy cells is not yet understood.
This project builds on recent findings in the host laboratory that the AAA+ ATPase complex of VCP can mediate the disaggregation of Tau fibrils in a cellular model. Consistently, autosomal dominant VCP hypomorph mutations have been found to exacerbate Tau pathology in patients. I will use live cell fluorescence imaging and advanced single-molecule tracking to investigate the mechanism of VCP and cooperating factors in Tau disaggregation in real time. Stable reporter cell lines will be generated in which components of interest carry self-labeling affinity tags to introduce fluorescence signals for single-molecule monitoring. The planned research will provide new insights into the cellular pathways of fibril decomposition and may benefit the development of new therapeutic strategies for tauopathies. The experimental approach to be established in this study can be applied to investigate disaggregation in other neurodegenerative disorders, including Huntington’s and Parkinson’s disease.
