NeuTARGETs: Targeting the propagation of pathogenic protein assemblies in neurodegenerative disease
Alzheimer's disease & other dementias|Parkinson's disease & PD-related disorders
Similar to prion diseases, more common fatal neurodegenerative diseases such as Alzheimers and Parkinsons disease are linked to the aggregation of different proteins (including Tau, Abeta and alpha- synuclein in the brain of affected patients. Furthermore most of the resulting brain lesions initially appear in specific brain areas and the pathology progresses along interconnected areas in a predictable manner. Interestingly, it has been shown that similar to the prion protein, these proteins are able to act as seed and to cause the aggregation of the normal protein. Therefore propagation of the aggregates in the brain could be a common mechanism for the propagation of these diseases.
In this proposal we want to identify the conditions that lead to aggregation of Abeta and a-synuclein, respectively in Alzheimers and Parkinsons and to identify possible targets to perturb the formation and the propagation of the aggregates. We will also analyze the pathway of spreading of these aggregates between neurons in order to identify specific target to stop their diffusion in the brain.
