L'hypoxie moléculaire comme stratégie thérapeutique pour la maladie de Parkinson (description en anglais)

Objectifs

The overall objective of this project is to determine to effect of an hypoxia-mimicking drug in rodent models of Parkinson’s disease.

Résumé

Parkinson’s disease is a multifactorial disease characterized by the progressive loss of nigral dopamine neurons. Interestingly, a large percentage of patients report improvements in symptoms when mountain hiking or during flights at high altitude which could be due to the hypoxic environment. It could also explain why smoking, which produces transient hypoxia, is protective in Parkinson’s disease. Experimental hypoxia has been shown to provide therapeutic benefit in several conditions. However, at sea level, the clinical translation of hypoxia is challenging and can only be performed using hypobaric chambers that can replicate the effect of altitude. Drugs targeting components of the hypoxic response fail to mimic the entire molecular cascade.
In this project, we propose to test a new molecule that strengthens the binding of oxygen to hemoglobin thereby closely replicating an hypoxic state. This drug will be tested in two complementary models of Parkinson’s disease.
