Team 3 – Biology and physiopathology of the spinal cord
Our team focuses on the biology and physiopathology of the spinal cord, as well as the peripheral nervous system. Our research strategy is built around four main axes:
- Modulation of excitability and inflammation in amyotrophic lateral sclerosis (ALS),
- The role of neuromuscular junctions in motoneuron degeneration,
- The effects of magnetic stimulation on regeneration and repair following spinal cord injury (SCI) and in ALS,
- The effects of electrical stimulation on the growth and guidance of peripheral nerves after complete injury and axonal outgrowth in vitro.
These projects combine in vitro and in vivo approaches, utilizing cutting-edge methods such as in vivo electrophysiology, chemogenetics, single-nucleus RNA sequencing, advanced imaging, and electroactive biomaterials. As a cross-cutting innovative approach, we are developing a scalable, non-invasive method for continuous 24/7 monitoring of motor activity in mice.
Our overarching goal is to generate fundamental insights with strong translational potential for incurable diseases such as ALS, peripheral nerve injuries, and SCI.
