Wnt-Ryk signaling in the establishment of major axon tracts in the embryonic mouse brain (2007–2009)

The corpus callosum is the major interhemispheric commissure in the human brain, comprising approximately 3 million myelinated fibers which connect homologous regions in the neocortex. To date more than 50 different human congenital syndromes have been described in which the corpus callosum does not form leading to epilepsy and mental retardation. We have identified a new guidance molecule (Ryk) which is crucial for corpus callosum formation. This project aims to dissect that molecular mechanisms controlling Ryk signaling during corpus callosum development. Our analysis of Ryk function will advance our understanding of the molecular mechanisms underlying the formation of this important commissure.
