On November 8th, 2013, The Global Health Innovative Technology Fund (GHIT) announced the winners for their first Request for Proposals 2013-001 (RFP 2013-001) within which GHIT will fund several new global partnerships between Japanese and non-Japanese organizations for the development of new innovations for the patients in the developing world inflicted by infectious diseases.

CellFree Sciences is very grateful to have received in a partnership together with the Program for Appropriate Technology in Health's (PATH) Malaria Vaccine Initiative, based in Seattle, Washington, USA, and the Proteo-Science Center (PROS) at Ehime University based in Matsuyama, Ehime, Japan, US$ 600,000 from the GHIT Fund for the joint development of a novel screening method for finding new vaccine candidates for malaria.

Malaria is a mosquito-borne infectious disease caused by parasitic protozoans (an unicellular microorganism) that in severe cases and lack of treatment can lead to the death of infected patients. The disease is widespread in large parts of Africa, Asia, and the Americas, where the World Health Organization (WHO) reported for 2010 some 219 million documented cases of malaria. In that year only the disease may have killed about 660,000 people including a high number of children according to estimations of the WHO. Although malaria is one of the greatest health burdens of mankind that in particular damages the prospect of poor people and the developing world, as of today, it had not been possible to develop an effective vaccine against the disease.

One of the biggest problems in developing malaria vaccines is that only a very small number of potential vaccine components can be screened because of persisting problems in the preparation of proteins from parasitic protozoans. To overcome this problem scientists at Ehime University and CellFree Sciences have developed an innovative wheat germ cell-free protein synthesis technology that allows scientists to produce large numbers of malaria vaccine candidate proteins. Under the new initiative funded by GHIT, the PATH Malaria Vaccine Initiative will develop antibodies against parasite proteins prepared by Ehime University and CellFree Sciences to evaluate which of those proteins may induce the most effective immunity against the disease. This screening process will hopefully reveal new malaria vaccine candidates for further testing and evaluation in clinical trials.

"The GHIT Fund will play a decisive role in bringing Japanese know-how and investment to the global fight against infectious diseases." commented Dr. Matthias Harbers, the responsible project manager for this program at CellFree Sciences. "This project is a very good example for this as it is very much based on the prominent malaria vaccine research at the laboratory of Professor Tsuboi at Ehime University. In combination with the expertise at the PATH Malaria Vaccine Initiative, we believe this project will certainly make a significant contribution to the development of new malaria vaccines."

"We are excited to be part of this important project made possible by the funding of GHIT", added Satoshi Ozawa, CEO and President of CellFree Sciences. "With the efficiency of our protein expression system, I believe that we can make an important contribution to the development of new malaria vaccines in line with the objectives of the GHIT Fund. It is our sincere hope that this project will help to develop the vaccines needed for effective malaria eradication efforts."

Please be advised that the recent earthquake and tsunami have not inflicted any damage on our offices, facilities, and families both in Matsuyama and in Yokohama, and that there has been no disruption in shipments of our products. The subsequent trouble at the nuclear power plant in Fukushima is unnerving, but Yokohama being 250 km south of Fukushima and Matsuyama farther to the southwest, we know the best we can do is staying well-informed and level-headed. Many of you have asked us about our health and safety, and we are grateful for your concern.

On November 24, 2008, the National Institute of Advanced Industrial Science and Technology (AIST) announced the production of its “human protein factory” infrastructure for in vitro proteome research. The infrastructure includes a comprehensive collection of human Gateway entry clones of nearly 15,000 human genes, approximately 70% of the human genome, and their wheat germ cell-free protein expression data.

Synthesized in the wheat germ cell-free expression system, nearly all of those clones yielded proteins with soluble fractions. The research that led to the construction of the infrastructure was reported by Goshima and colleagues [1] in Nature Methods, December 2008, which was reviewed by Hartley and colleagues [2] in the same issue.

Information and expression data of the Gateway entry clones including SDS-PAGE patterns are available in the URL of Human Gene and Protein Database (HGPD) at and information of the purchase of those clones is obtained by clicking Clone Inquiry in that URL.

Malaria Vaccine Development - Malaria Protein Synthesis

“Research at Ehime University among 23 innovative technologies selected and supported by Japanese Government,” Ehime Shimbun, May 21, 2008

The Council for Science and Technology Policy chaired by Yasuo Fukuda, Prime minister of Japan, drafted a strategy for developing innovative technologies and selected 23 research projects as the global cutting-edge technologies. They will be funded from the next fiscal year onward by a new public fund established by the Council for accelerating the development of those innovative technologies. Among the recipients of new funding is the Malaria Vaccine Development Project at Ehime University using the Cell-Free Protein Expression System developed by Dr. Yaeta Endo of Ehime University.

The above strategy is aimed at enhancing the international competitiveness of industries, constructing healthy society, and strengthening the security of Japan and the rest of the world by supporting innovative technologies expected to have ripple effects on society. The selected technologies, one of which is regenerative therapy using iPS cells, encompass broad areas including information and communication technology, healthcare, and agriculture. Of the fiscal 2008 outlay of 1.4 trillion yen for science and technology promotion, 1% will be allocated to the innovative technology strategy.

In search of malaria vaccine candidates, Ehime University has started a joint research project with international collaborators including an Australian institute. In the heart of this search is the cell-free protein expression system, whose advent has made it possible to efficiently synthesize malaria parasite proteins beyond the limit of the commonly used E. coli system.

The Council for Science and Technology Policy states that the plant-based protein synthesis technology used in the Malaria Vaccine Development Project at Ehime University permits efficient production of a variety of malaria-related proteins for malaria vaccine development. By this statement, the Council expresses high expectation for the production of malaria vaccines in near future.

Novel Analytical Method for Searching for Inhibitors of Cancer-Related Proteins

Joining forces with Taiho Pharmaceutical Co., Ltd., CellFree Sciences Co., Ltd. developed a novel analytical method for searching for inhibitors of cancer-related proteins. This followed Taiho's discovery of proteins including target proteins that play roles in cancer cell growth. We synthesized those proteins in our wheat germ cell-free expression system to develop a technique for high-throughput screening of compounds.

The new method permits (1) high-throughput search for inhibitors and (2) speedy identification of a specific protein that may be affected by an inhibitor and the specificity thereof. Its successful development is attributable to high-speed expression of active proteins using a desktop robot, Protemist DT, coupled with our newly developed high-speed protein modification and high-sensitivity assay technology.

Multiple units of Protemist DT have been in operation, besides Taiho, at Kyoto University, University of Tokyo, and other major research centers in Japan. Our services include development of tools for the functional analysis of proteins and protein-protein interaction. Two units of Protemist DT II, a new version of DT, have been added to the CESG of the University of Wisconsin, Madison.
