Finding a therapy against Parkinson’s disease remains a major challenge. The project proposed by this research team aims to explore the therapeutic potential of specific classes of bioactive compounds extracted from venoms of vipers and scorpions for the treatment of Parkinson’s disease. The project builds on the partners’ unique expertise and is a perfect example of the win-win benefits of conducting South-North collaborative research, as promoted by EXAF.
Parkinson’s disease (PD) is the second most prevalent neurodegenerative disorder for which there are no effective treatments today. PD is caused by the loss of dopamine-producing neurons in specific brain regions but eventually spreads to different brain regions as the disease progresses.
One key characteristic feature of the disease is the accumulation of proteinaceous aggregates, composed of the protein alpha-synuclein (α-syn) in the affected brain regions. Increasing evidence suggests that the aggregation of the α-syn and its cell-to-cell propagation in the brain play central roles in the initiation and progression of PD and several other neurodegenerative diseases that are collectively known as synucleinopathies. Alpha-syn aggregates are toxic and bind to cell surface receptors such as integrins, matrix metalloproteases, or ionic channels on neuron and/or microglia, leading to chronic neuroinflammation and neuronal damage. Accordingly, we hypothesise that specific ligands of integrins, matrix metalloproteases, and/or ionic channels could have a therapeutic effect on Parkinson’s disease.
In this project, we aim to use an integrated platform of validated preclinical models and drug discovery assay developed in the Lashuel lab. The objective is to screen, identify and validate anti-PD drugs from vipers and scorpions venoms and assess their therapeutic potential for the treatment of Parkinson’s disease and other synucleinopathies.
