Cooperative Research on Bioscience between Japan and Foreign Countries, especially USA and European Countries.

目前已完成以下3个项目：1. 1990年3月2日至4日，在Howaii的檀香山的东/西中心举行了关于在动物细胞中生产生物活性材料的最新进展的美日研讨会。24名与会者（两国各12名）就以下主题进行了发言和讨论：a）建立新的表达载体系统。B）蛋白质分泌的分子机制c）蛋白质的功能结构d）蛋白质分子的设计e）基因表达的分子机制f）信号转导.我们访问了位于Prais的CNRS，并与Stuyck-Taillandier博士、Rieu博士、Berthillier博士、Aubujealt女士、Volfin博士和Prdo博士讨论了未来的合作研究体系和科学领域。我们还参观了位于斯特拉斯堡和马赛的CNRS研究所。五位年轻的研究者（K.石川岛Kubo，M. Yoshida，A.土屋和Y. Nishimura）访问了美国的几个研究所和大学，如洛杉矶大学，索尔克学院，麻省理工学院，加州大学，DNA研究所，哈佛大学和冷泉哈佛研究所合作完成。

The following 3 projects have been achieved:1. US-Japn workshop on Recent Progress in the Production of Biologically Active Materials in Animal Cells was held at East/West Center, Honolulu, Howaii on March 2-4, 1990. Twenty four (12 each from both countries) participants presented and discussed on the following topics, a) Establishment of new expression vector systems. b) Molecular mechanisms of protein secresion c) Functional structure of proteins d) Design of protein molecules e) Molecular mechanisms of gene expression f) Signal transduction.2. We visited CNRS in Prais and discussed future collaborative research system and scientific fields with Dr. Stuyck-Taillandier, Dr. Rieu, Dr. Berthillier, Ms. Aubujealt, Dr. Volfin and Dr. Prdo. We also visited CNRS Institutes in Strasbourg and Marseille.3. Five young investigators (Drs. K. Ishikawa, I. Kubo, M. Yoshida, A. Tsuchiya, and Y. Nishimura) visited several Institutes and Universities in the USA, such as Univ. Los Angeles, Salk Inst.,MIT,Univ. California, DNAX Inst., Harvard Univ. and Cold Spring Harvor Inst. and made collaborative works.
