Cell-cell communication in the mammalian nervous system

Presentation

Research in the team focuses on elucidating mechanisms that govern development of the nervous system and how genetic alterations of this complex developmental program may lead to brain disease in the adult. 
We investigate cell-to-cell communication via the Eph/ephrin signaling pathway, mostly in the context of neurogenesis and neural progenitor specification and maintenance. Our studies combine in vivo experimentations on genetic mouse models, ex vivo experimentations on tissue explants and in vitro cultures of primary neural progenitors, brain tumor stem cells and cell lines.
