Long Name Inhibiting misfolded protein propagation in neurodegenerative diseases
Description Inhibiting misfolded protein propagation in neurodegenerative diseases. Both AD and PD are characterised by the progressive loss of brain cells. Recent evidence suggests that this loss may be due to the release and uptake by brain cells of specific aggregated proteins (misfolded proteins which clump together leading to a progressive spreading of the degeneration). If these processes could be blocked, disease progression could be halted. However, the forces driving these processes are currently poorly understood. Working to change that is the IMPRiND project, which aims to understand how these aggregated proteins are handled once inside brain cells and how they are moved from cell to cell. To do this, the project team will work collaboratively to develop standardised tools and tests to establish disease-relevant mechanisms that could be targeted by drugs in the future.
Objectives 1. Identify disease-relevant misfolded assemblies, imprint their biological properties in vitro and/or in cellulo and generate homogeneous populations in order to assay and interfere with their pathogenic effects. 2. Develop and miniaturise assays to monitor up-take, secretion, clearance and oligomerisation using bimolecular fluorescence complementation of oligomeric species or transfer of untagged assemblies to fluorescently labelled fibril-naïve cells and measure markers of early proteotoxicity that are suitable for high throughput or high content screens. 3. Perform genetic screens based on disease-relevant gene/protein networks and assess druggability of identified targets. 4. Deliver robust validation assays for these molecular events in complex cellular systems with greater functional resemblance to the native milieu of the brain such as iPSC-based models and organotypic cultures or simple model organisms such as Drosophila or zebrafish. 5. Improve existing animal models in order to standardise pathological readouts for in vivo validation of modifiers, correlate them with novel peripheral or in situ markers using microdialysis to accelerate the assessment of therapeutic interventions and relevance to humans, e.g. by transplantation of human iPSC neurons in animals.
