Summary:

The overall aim of this proposal is to lay the groundwork for the successful application of regenerative medicine in central
nervous system (CNS) disorders involving neuronal loss. The adult CNS has potential to produce new neurons and regenerate after injury. In practice, however CNS injury favors the generation of new astroglial cells and the glial scar versus axonal outgrowth and neurogenesis. Inhibition of astrogliogenesis and the glial scar could therefore contribute to CNS repair.

First, we will unravel the pathways that regulate astrogliogenesis by means of largescale genetic and pharmacological screenings on novel cellular models of this process. Second, we will create innovative optogenetic systems to target and control the behavior and fate of specific subpopulations of neurons and glia. And third, we will adapt new microfluidic devices to the study of astrogliogenesis.

We expect to provide new putative therapeutic targets and strategies for CNS regeneration. However, our proposal could have great impact on a wide range of scientific fields beyond regenerative medicine.
