| Outline of Final Research Achievements |
We analyzed the functions of proteoglycans in the nervous system using two model organisms: Drosophila melanogaster and mouse. We revealed that syndecan (Sdc) and glypican (Dlp) play opposing roles in the neurotransmission at Drosophila neuromuscular junction and in the locomotion of larvae. We also found that Dlp regulates synaptic plasticity at the neuromuscular junction. Furthermore, we found that chondroitin sulfate proteoglycans play critical roles in the neuronal migration and polarization of excitatory neurons in the developing mouse neocortex
