    This lab researches immune markers that reflect the early stages and pathophysiology of different types of diseases including cancer, rheumatoid arthritis and Castleman's disease. The laboratory has its own independently developed method of quantifying interferon production ability, and provides affiliated clinics and other medical institutions with information on immune markers and immune function. This data helps these institutions to early detect and treat cancer.

    Since the 2011 Fukushima Daiichi Nuclear Power Station incident, this lab has been part of a government project that provides Fukushima residents with the support required to help them maintain optimal immune function to overcome the effects of low-dose radiation exposure.

    Since 1993, we have made important discoveries about the role of a red blood cell growth factor, erythropoietin, in the growth and differentiation of early mouse embryos. It also is apparent that this signaling system is expressed in nearly all cancer cells.

    Subsequently, we discovered EMP9, a peptide that disrupts this erythropoietin signaling system and established the company EpoMed Ltd. to use EMP9 to develop an anti-cancer drug. Since then, we have become independent of that company and have created this drug discovery laboratory as a separate entity; in this laboratory we are now focusing on creating treatments for keloid tumours.

Our goal is to explore and analyze the state of medical science in the near future and its prescription for humanity, and to publish our results in an easy-to-understand manner.

  • Laboratory for Human Diseases Models

    Laboratory Director
    Yoichiro IWAKURA

    Many genes have been implicated in the pathogenesis of autoimmune and allergic diseases. Clarifying the role of these individual genes will enable us to better understand the pathogenic mechanisms, leading to the development of new therapeutics. This laboratory has produced more than 100 strains of gene modified mice in which specific external genes have been introduced into their DNA (transgenic mice) or in which gene functions have been silenced (knockout mice). Through these activities, we have identified a plethora of genes involved in disease development and have clarified their pathogenic roles, mainly of genes implicated in autoimmune diseases and allergies. These areas are specifically important as there are many patients worldwide who are depending on the development of effective treatments. We are committed to helping to find meaningful cures for autoimmune and allergic diseases, and as such, we offer our mouse models to scientists who want to use them in their research. If you are such a scientist, please do not hesitate to contact us.

    This laboratory acts as an umbrella organization for clinical trials and at the same time conducts research for new cancer therapy. Charged particle radiotherapy that uses protons, neutrons, and other charged particles, is being used as a more high-precision cancer treatment. However, this type of treatment is done with large devices that have many restrictions in how they can be used; as such, charged particle radiotherapy is not yet widely available.

    This laboratory is working to create a new generation of particle radiotherapy that is more compact. Using state-of-the-art technology, we are developing a miniaturized boron neutron complementary therapy (BNCT) device. Our goal is to create a very compact design that requires little space, has emits low levels of radiation and has excellent safety features.

    At the same time, comprehensive research is underway to develop new boron agents that accurately target and accumulate in cancer cells and will lead to safer and more effective therapies for BNCT.

    With the internationalization of medical care, there is an urgent need to accept patients from overseas, dispatch medical personnel overseas, and provide technical support for medical devices and operations. However, before this can be achieved, there are language, financial, institutional and other problems that need to be addressed.

    In order to help solve these problems, we create textbooks and do practical exchanges to promote research on international collaboration in medical care.

    The laboratory supports the XPRIZE HEALTHSPAN project which is an international competition with a total prize purse of US $100 million. In this project, researchers, clinicians, pharmaceutical industry experts, investors, government agencies and various stakeholders are collaborating to explore new approaches to ageing. The ultimate goal of the competition is to develop treatments to extend human life expectancy by 10+ years and healthy lifespan by 20+years by 2030. The basic premise of this project is the Information Theory of Ageing which argues that aging is a result of the ambiguity present in information surrounding epigenetics.

    Exercise, nutrition, psychological health and environmental interventions have been shown to be effective in preventing ageing, and taking appropriate measures can delay the ageing process and extend healthy life expectancy. However, the core of this seems to be predicated on controlling aging through epigenetics. The Ageing Clock, particularly, the epigenetic clock, is used to assess biological age, as opposed to calendar age and it is an important tool for advancing anti-ageing medicine. Biological age will also be an important theme at the 2025 World Exposition in Osaka and the laboratory plans to share useful information with attendees that can potentially assist them in reducing the effects of aging.

    This laboratory has been further advancing its research on very pure electrolysed hypochlorite water with low coexistent ion concentrations. This work was first initiated by our predecessor, the Functional Water Laboratory, and we are currently deepening our understanding by delving into the mechanisms and effects of this solution inactivates various pathogens.

    The laboratory is equipped to perform large-scale testing in a simulated space environment, and has BSL3 functionality to explore more effective disinfection methods in space using hypochlorite water. the laboratory recognizes the importance of proper storage and management of pathogen resources such as bacteria and viruses in future infectious disease control, and is therefore poised to launch a Pathogen Resource Bank. By collaborating with various companies, universities and research institutions, this laboratory aims to lead research on functional water and infection control.

    In recent years, it has become clear that the diverse functional nucleic acids contained in many foods have positive and negative impacts on human health. Based on the idea that we consume not only nutrients but also functional information from the foods we eat, we are actively promoting the exchange of information between the medical and agricultural scientific communities.

    We are conducting research to find scientific evidence on measures that will enable Japan, the world's largest food importer, to secure a stable supply of safer and more health-enhancing agricultural products.

    This laboratory is/* collaborating closely with the International Society of eSports Medicine, to achieve its major goal of using eSports to support health and longevity. As such, we are now exploring the use of foot treadmill controllers specifically for the elderly, as well as collecting evidence on the effects of playing e-sports on brain function and its ability to reduce the effects of -ageing.

    Additionally, we are also continuing with research from our previous laboratory that focuses on devices that use AI to monitor brain and cardiopulmonary functions of the elderly in-time. As part of the research on information infrastructure, we are also studying the tokenization of individual biometric data as Non-Fungible Tokens (NFT) to enable effective data utilization while protecting individual privacy. In particular, since it protects individual data, we consider the NFT technology to be essential for advancing research and improving clinical applications within the healthcare system.
