Neurons of the central nervous system (CNS) do not normally regenerate injured axons. This regenerative failure causes severe consequences for victims suffering from traumatic injuries, stroke or certain neurodegenerative/neuroinflammatory diseases. The Fischer lab is involved with research to understand the molecular mechanisms underlying the failure of axonal regeneration in the CNS. Another goal is the development of novel strategies for CNS repair. To reach these goals the following approaches are used: 1) Screening and identification of novel neuroprotective and axon growth-promoting drugs/factors; 2) Identification and characterization of genes and signaling pathways associated with neuroprotection and axon regeneration; 3) The development and optimization of gene-therapeutic approaches aiming to improve axon regeneration in vivo.
