Fields of research

Neurological and psychiatric diseases

Research Theme

Our project is driven by two major complementary objectives:

1) to characterize the mechanisms involved in the progression of nerve cell death in neurodegenerative disorders and especially Parkinson’s disease (PD);

2) to identify functional alterations underlying key clinical symptoms in these disorders. To that aim, we concentrate on the populations of dopaminergic (DA) and cholinergic neurons that are preferentially affected in PD. Our hope is to identify therapeutic targets to slow the progression of neuronal loss and to alleviate symptoms originating from non-DA lesions which represent two major unmet needs for patients suffering from PD. The main targets analyzed are oxidative stress, the role of calcium homeostasis, electrical activity and neuroinflammatory processes.

Pathological spreading of patient-derived Synuclein fibrils in mouse

Project

Our working hypothesis is that alpha-synuclein (SYN) assemblies with different structural characteristics or ‘strains’ display distinct spreading, tropism, clearance and neurotoxicity. The goal of the project is to test in vivo (mouse) the pathological spreading capacity of different fibrillary SYN assemblies obtained by protein misfolding cyclic amplification (PMCA) of patient-derived brain aggregates (PD, MSA, DLB). Technics such as stereotaxic brain injections, immunohistochemistry and image analysis will be employed.
