Post-doc position

Myelination of axons is an essential step to ensure the rapid propagation of action potentials by saltatory conduction, a mechanism that relies on the nodes of Ranvier. These short unmyelinated axonal domains are highly enriched in voltage-gated sodium channels (Nav), which allow the regeneration and propagation of the action potentials by depolarization of the plasma membrane. Multiple Sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system (CNS), which corresponds to the first source of non-traumatic neurological handicap in young adults in Europe and the USA. It is a complex disease with an inflammatory process associated to demyelinating attacks, followed by repair of the lesioned brain and spinal cord. The repair process (remyelination), relying on precursor cells of the oligodendrocytes (the myelinating glial cells of the CNS) can be extensive, but remains most of the time insufficient, leading to irreversible damages of the denuded axons associated with permanent neurological deficits. Treatments available presently only target the immune aspect of MS, and although they allow to decrease the frequency of relapses, their efficiency on long term progression of the disease is not proven. Promoting repair in order to protect axons and limit handicap progression is thus one of the key challenges in MS.

Our research group focuses on the mechanisms underlying (re)myelination in the central nervous system. We are in particular interested in how to promote an adequate repair following demyelination, using various models ranging from in vitro primary cell cultures to demyelinating models in mouse.

In the present project, supported by an ANR Jeunes Chercheurs, we want to focus on the mechanisms of early node of Ranvier reassembly following demyelination and how it could participate in the dialog between demyelinated neurons and the various surrounding glial cell types participating in the remyelination process. In particular, we want to evaluate whether these interactions could have an impact on remyelination modulation and neuroprotection.

Applicants should have completed a PhD in Neurosciences (see detailed profile below) and have less than 1 year post-doctoral experience.
