    Proliferation control of neural progenitor cells

    Neuroblasts are the progenitor cells of the Drosophila central nervous system. Proper control of their proliferation to generate the right number of neuronal cells during development is essential to finally built up a functional nervous system. We are analysing a number of mutations causing hypo- or hypertrophy of the adult nervous system. In particular, we are interested in cell cycle and growth control of neuroblasts. Recently, we extended our research to the question whether and how daytime dependent cellular metabolism has an impact on neuroblasts.
