After completing my PhD on the Duchenne dystrophy gene (DMD) in Dr A Kahn's lab at the Cochin Hospital in Paris, I joined Michel Lazdunski's lab in Sophia Antipolis as a post-doc to work on K+ channels. In this lab, I cloned a new family of voltage-gated K+ channels which need to associate with other subunits to generate fully functional channels (Hugnot, EMBO, 1996). I also contributed to the cloning of several members of inward-rectifier K+ channels (Lesage, FEBS Letter, 1994).
I then redirected my research topic to the neural stem cell field by joining Dr J Sinden and Dr J Price’s lab at the institute of psychiatry (IoP) in London and then Dr A Privat’s lab in Montpellier. In these labs, I focused on the control of self-renewal and differentiation of neural stem cells especially in the adult spinal cord. My main interest was the role of extracellular signals (cytokines) and transcription factors in the control of the differentiation process (Deleyrolle L, Stem cells, 2006, Dromard, Stem Cells, 2007). I provided an in depth description of the neural stem cell niche located around the central canal of the spinal cord (Sabourin, Stem Cells, 2009) and in collaboration with the Montpellier Hospital (Dr L Bauchet), we showed for the first time the presence of neural stem cells in the adult human spinal cord (Dromard, JNR, 2008). In the spinal cord, the niche is in a dormant state but can be reactivated by lesions. One current project aims at deciphering the molecular mechanisms underlying the balance between dormancy and activation of the niche.
More recently, I teamed up with Pr H Duffau, neurosurgeon, and Pr N Bakalara, biochemist, to create a new team dedicated to gliomas, the most frequent type of brain tumors. High grade gliomas contain a subpopulation of cancer stem cells which are thought to be responsible for tumor recurrence after treatment. We showed that these cells lose their tumorigenic potential and can be differentiated in electrophysiologically-active neurons by the expression of a single neurogenic gene (Ngn2) (Guichet, Glia, 2013 + patent). More recently, we found that activation of the Notch pathway in these cells dramatically stimulated the angiogenic tumoral process (Guichet, Stem Cells, 2013, in revision). A large part of my project is now dedicated to low grade gliomas (grade II WHO). We have identified a 22 gene signature which allows a better prediction of patient survival compared to the WHO grade II/III glioma classification (Reme, Plos One, 2013). We are currently developing in vitro models for low grade gliomas using patient’s resection so as to set up innovative therapeutic strategies.
