The first area of research that our team focuses on is the understanding of the mechanisms that maintain the peripheral myelin sheath, taking into account its physiological and pathological aspects. We work on deciphering the maintenance effectors – by taking three aspects that play a role here into account: (i) Schwann cells, peripheral nerve myelinating cells, (ii) relationships between Schwann cells and axons, and (iii) relationships between Schwann cells and the extracellular matrix – and also on characterizing process dysfunction under pathological conditions (genetically-determined neuropathies and acquired neuropathies, in particular inflammatory) on ill individuals and in animal models.
We also work on a second research area that focuses on therapeutics in peripheral neuropathies. This includes developing peripheral neuropathies models (in particular cellular models) which will be used for testing different therapeutic approaches, such as using hydrogels for the sustained release of bioactive molecules, and screening drug candidates. A second theme deals with small fiber peripheral neuropathies. Various approaches, on animal models and on humans, are currently developed on these frequently painful types of neuropathies, which are highly prevalent among the general population.
