University of Tsukuba


The University of Tsukuba is located in the suburbs of Tokyo and is at the heart of Tsukuba Science City —Japan’s largest “science city,” which has 29 national research institutes and about 150 private research organizations. The University operates on the principle that it is open to all.

The University of Tsukuba aims to cross the borders that separate a variety of organizations, such as those between nations, research institutions, and fields of study. The University’s network is expanding globally. In particular, the University has entered into ten campus-in-campus arrangements with universities in eight countries and regions, thereby promoting close cooperative relationships between education and research. At present, the University hosts approximately 2,400 study abroad students from more than 110 countries and regions.

Collaboration is essential in order to achieve high-quality outcomes with limited resources. As an example, the University is actively engaged in an exchange of talent and joint research that goes beyond the conventional university framework at nationwide joint-use institutes that encompass the four fields of computational science, marine science, plant science, and plasma research.

The Research and Development Centers are the part of the University’s quest to pursue research and innovation that result in benefits for society. Externally funded, seven centers are newly established as industry-university-government partnerships for joint research in areas of high demand from the community.

The University is also proactively engaging in the support of venture corporations. Thus far, a total of 144 companies have originated from the University of Tsukuba, including Cyberdyne, Inc.

A frontrunner in university reform in Japan, the University is creating a flexible education and research structure as well as a university system to meet the needs of the next generation. It aspires to be a comprehensive university, continuously meeting new challenges and developing new areas. The foremost mission of a university is to provide an environment that allows future leaders to realize their full potential. The University gives students the opportunity to develop their individuality and skills through an education that is backed by cutting-edge research.

Cancer-secreted protein shuts down anti-tumour immunity



Drugs that target the soluble form of a protein called CD155 could help enhance the anti-tumour activity of the immune system’s natural killer cells.

Researchers from the University of Tsukuba in Japan engineered mouse melanoma cells to produce soluble CD155, a protein expressed by many tumour types.

In its membrane-bound form, CD155 normally interacts with a receptor called DNAM-1 to enhance the anti-cancer activity of various immune cells, including natural killer cells. But in its soluble form, the team showed, CD155 interferes with the usual DNAM-1–mediated ability of natural killer cells to transfer cytotoxic materials into tumour cells.

As a result, the soluble CD155–producing melanoma cells grew more readily in the lungs of mice compared to cancer cells that could not make this protein.

“These are striking results that show how a single protein can drastically change the fate of a tumour,” said senior study author Kazuko Shibuya in a press release.
