Outline
We detect viruses from various urban environments (sewage, public spaces, medical sites, etc.) by utilizing new ultra-sensitive genome amplification technology, acquire their genome information, and publish data from public databases and portal sites that we cooperate internationally. We will also analyze genome mutations and build a mathematical model for epidemic countermeasures. As a whole, we will build a data infrastructure that can handle various emerging infectious diseases.

Our team will develop highly sensitive detection methods for the novel coronavirus. New materials will be developed that can control adsorption and desorption of viruses to establish efficient concentration methods. These will be achieved by self-assembled polymers, inorganic crystals and functionalized carbon that have high adsorptivity and/or high water permeability while blocking viruses. Furthermore, in order to efficiently remove viruses, we will develop new materials such as polymer nanostructured films, photocatalytic inorganic crystals, and carbon filters to realize excellent virus removal and inactivation performance.

Outline
COVID-19 is characterized by a diversity of symptoms, with the majority of infected people remaining asymptomatic or mild, while some become severe or fatal. Compared to substantial data collected in hospitals after the onset, data before the onset has not been sufficiently accumulated, and no methodology has been established to assess the risk of developing illness and becoming severe for each individual in advance. In this study, we will collect saliva and nasopharyngeal swab samples from thousands of healthy and asymptomatic individuals by exploiting the large-scale socieal PCR testing system that we have already started to build. We will comprehensively measure human- and microbial-derived DNA and RNA contained in these samples, and develop a method to evaluate the individual risk of developing illness and becoming severe before the onset of disease through an approach that combines machine learning with statistical and mathematical modeling. We will also develop a model for predicting epidemic trends that takes into account the diversity of the disease risk for each individual, with the aim of creating personalized infection-control strategies that determine when, who, and what interventions are most effective.

Outline
The spread of the novel coronavirus (SARS-CoV-2) has revealed issues regarding the number of polymerase chain reaction (PCR) tests that can be conducted per day and the testing system and organization in Japan. This research aims to realize a mass-automated testing system by utilizing robotics technology and information management technology to prepare for future virus mutations. We present an innovative concept for constructing a new mass-automated test system with system flexibility and continuity and verify the effectiveness of the proposed concept using a partial model. To realize the mass-automated testing system, first, the requirements and technology trend surveys and issues will be extracted, and a new concept will be created from the results. Second, the element technology development of the sample accumulation (pre-stage processing) process system and the PCR inspection process system, which are the key elements for efficiency improvement and system flexibility in all inspection processes, will be conducted. Finally, an integrated system including inspection information will be constructed, and its effectiveness will be verified using the partial model based on the concept. From the results of this research, it will be possible to realize a safe and secure society that can quickly and accurately grasp the mass occurrence of future coronavirus mutations and the next pandemic.

Outline
The development of drugs against SARS-CoV-2 is underway worldwide, however, there is no specific drug for SARS-CoV-2 yet. This is because it takes time to create a drug for a specific target. To respond rapidly to emerging infectious diseases such as COVID-19, it is necessary to establish general therapeutic strategies applicable to viral infections based on a new concept. Since GTP is a cellular energy molecule used for protein synthesis including viral proteins, we focused on host energy metabolism, on which viruses depend for their replication. We consider that regulating GTP metabolism may inhibit the synthesis of viral proteins and could be a general strategy for antiviral therapy that can apply to any type of virus. In this research, we will develop drugs based on this concept. Furthermore, by combining the development of novel compounds targeting viruses, we aim to the synergistic effects of two different drugs and establish a therapeutic strategy that is widely applicable to viral infections including COVID-19.

Outline
In the era of coexistence with emerging infectious diseases represented by COVID-19, we will develop a system that utilizes a supercomputer, which can be a common social foundation for risk assessment of droplets and droplet nuclei infection. Furthermore, we will propose measures to reduce the risk of infection in the age of living with emerging virus by utilizing the obtained system. In order to control and reduce the risk of infection of residents to COVID-19 in the indoor environment, the transport dynamics of viral droplets and droplet nuclei, which was difficult to directly observe and evaluate in the past, are evaluated by thermal fluid numerical simulation. The accuracy and reliability of the risk assessment will be drastically improved by integrating the simulation system by comprehensively analyzing the pharmacokinetics, immune system response, and physiological response associated with infection. The developed system is implemented on a supercomputer system to reduce the turnaround time for the risk assessment and to increase the number of corresponding test cases compared to conventional experiments and simulations. It will also be possible to create big data for AI learning.

Outline
In order to prevent the spread of various infectious diseases including the novel coronavirus and to reduce the pressure on medical institutes, there are needs to develop a simple diagnostic procedure and system by which a patient can perform an examination by himself/herself at home. In this project, target peptides that can recognize the molecular characteristic of various pathogens will be systematically selected from a gene library and incorporated into chemiluminescent proteins to construct a platform that will allow rapid development of light emitting molecular sensors that can recognize each pathogen. Furthermore, a smartphone-based diagnostic system will be developed that can easily confirm the infection at home by detecting the luminescence signal. These technologies will build the foundation to support the nation to coexist with the emerging and re-emerging infectious diseases, by the visualization of infection information and construction of infection prediction maps using smartphones.

Outline
Understanding the SARS-CoV-2 replication mechanisms in human is necessay to develop specific therapeutics for COVID-19. Currently, several cultured cell lines and primary cultured cells are used as SARS-CoV-2 infection models. However, there is no suitable model that reflects the infection and replication in human body. In this study, to elucidate the SARS-CoV-2 replication in the human respiratory tracts, we aim to develop a “respiratory organs-on-a-chip” equipped with nasal cavity, respiratory tract, and lung organoids that are differentiated from human ES cells and iPS cells. Then, using the respiratory organs-on-a-chip, we will analyze the mechanisms of SARS-CoV-2 replication pathogenesis. Such a human respiratory organs-on-a-chip, which reproduces the human upper and the lower respiratory tracts, will be an innovative tool for researches on various respiratory viral infections.
