| Research Abstract |
We developed various types of functional dendron-bearing lipids, which include gene delivery dendron lipids, temperature-sensitive dendron lipids, pH-sensitive dendron lipids, and MR imaging dendron lipids. We found that gene delivery dendron lipids achieved highly efficient gene transfection into culture cells through hydrophobic interaction and proton sponge effect. Temperature-dendron lipids were shown to provide a new type of temperature-responsive vesicles that undergo morphology transition at a specific temperature. pH-Sensitive dendron lipids formed highly pH-responsive vesicles with egg yolk phosphatidylcholine that release contents in the endosome of a cell. MR imaging dendron lipids were useful for detection of bio-distribution and accumulation of liposomes, which can lead to personalized chemotherapy. The dendron lipid technology is expected to contribute development of new efficient noninvasive cancer therapy.
