Research Abstract |
Chondroitin sulfate (CS) chains are major components of extracellular matrix in nervous system, and have a broad impact on various neurobiological phenomena. In this project, regulatory roles of CS in neuritogenesis were investigated using several model systems, and the key findings are as follows : 1) A plasma membrane-tethered cell adhesion molecule, contactin-1, can function as a neuronal cell-surface CS receptor, and mediates neurite extension promoted by an oversulfated CS variant, CS-E. 2) A morpholino-based knockdown of chondroitin 4-O-sulfotransferase-1, which contributes substantially to the in vivo construction of 4-O-sulfated CS, revealed the functional importance of the characteristic CS sulfation codes in motor axon guidance in zebrafish embryogenesis.
