Glycans are involved in a variety of important physiological events, including cell-cell recognition, adhesion, signal transduction, and quality control. Dr. Tanaka, a Chief Scientist in Biofunctional Synthetic Chemistry Laboratory, RIKEN, proposes "cluster heterogeneity" and "pattern recognition" of glycoclusters as new mechanisms for highly selective interaction in biosystems, and developed glycocluster-based drug delivery systems (DDS).
By combining Dr. Tanaka's glycocluster DDS and manufacturing technology of human type glycans by GlyTech, Inc., our team aims to develop innovative in vivo targeting technology and drug discovery supports.
