What is longevity? What factors do determine how long we live? We have discovered that methylation (the biological reaction to transfer the methyl group [-CH3]) has the key to determine the longevity by investigating the regulation of gene expression. The reaction is deeply involved not only in protein methylation, but also in that of DNA and RNA. To understand the longevity of multicellular organisms, we are approaching the molecular entity of the longevity by applying the techniques of genetics, biochemistry, chemistry, and metabolomics of mouse and C. elegans. Through advances of the longevity research, our laboratory is working on with the aim of knowing how long organisms can live and survive, and feeding back to the increase in the quality of health and life.

Cancer cells continue to proliferate as a population. This is the primary characteristic of cancer cells. Recent cancer research indicated that only cancer stem cells are capable of tumorigenesis, recurrence, and metastasis, and we originally discovered the phenomenon of stem cell induction, in which stem cell properties are newly acquired in a cancer cell population. Based on this discovery, we have been conducting research from a new perspective on the characteristics of cancer cells, such as the determination of cell division lifespan of non-stem cancer cells and the mechanism of release from the lifespan during stem cell induction, while analyzing the dynamics of cancer stem cells by visualization.

We aim to clarify bacterial survival strategies in the context of the establishment of infectious diseases or symbiotic status. We have found a group of genes named “esp (expression in minor subpopulation)” that are expressed in a minor subpopulation. Some were responsible for horizontal gene transfer and acquisition of antibiotics resistance genes. However, the function of many esp genes remains to be clarified, which must be clues for unknown bacterial properties based on population heterogeneity. Other topics include dynamics of nucleoid, and anti-virulence drugs.

Humans have built a highly integrated immune system as a biological defense mechanism against pathogenic microorganisms. However, infectious diseases are still the greatest threat to humankind even today. On the other hand, abnormalities in the immune system are also an essential cause of intractable diseases such as autoimmune diseases and allergies. In addition, cancers and rejection of transplanted organs are also issues that are directly related to the immune system. Our laboratory identified several novel immunoreceptors, including DNAM-1 (CD226), MAIR (CD300), Fcα/μR (CD351), Allergin-1, and Clec10a, which are involved in the development of inflammatory diseases, allergy, cancer, infectious diseases or autoimmune diseases. Our goal is to clarify the basic principles of the immune system, and then to develop innovative molecular targeting therapies for these intractable diseases.

Ho Kiong

In kinetoplastid parasites, post-transcriptional events have central roles in controlling gene expression. Recent studies suggest that certain transcripts are silenced by removal of 5’-cap structure and silenced in the cytoplasm. The silenced transcripts can reacquire the 5’-cap to regenerate translatable mRNAs. The purpose of this research is to elucidate how gene expression is regulated through mRNA decapping and recapping pathway. The mRNA recapping pathway could potentially expand the information content of genes by regulating abundance and stability of translatable mRNA. We are also interested in how RNA are repaired in the cells This is accomplished by understand the targets for RNA ligase, which act to join the the breakage in the RNA molecules in the cells.

Mechanisms underlying Germ Cell Formation
Germ cells are specialized cells that can transmit genetic materials from one generation to the next in sexual reproduction. All of the other cells of the body are somatic cells. This separation of germ and somatic cells is one of the oldest problems in developmental and reproductive biology. In many animal groups, a specialized portion of egg cytoplasm, or germ plasm, is inherited by the cell lineage (germline) which gives rise to germ cells. It has been demonstrated that the germ plasm contains maternal factors required and sufficient for germline development. Our laboratory aims to find the maternal factors for germline segregation, and molecular mechanisms regulating germline sex determination in Drosophila.

Our laboratory is interested in understanding the mechanisms of how glial cells contribute to neurogenesis, synaptogenesis, and neural circuits formations. Also, we have been investigating mechanisms by which glial dysfunctions cause an increased risk of neuronal disorders. Currently, we implement several projects, such as (1) microglial diversity regulated by extracellular micronuclei, (2) microglial maturation and purine metabolism, (3) atypical secretory pathway in neurons and astrocytes, (4) hypothermia control mediated by neuron-astrocyte interaction. Moreover, we have been developing tools and screening systems to elucidate abnormal posttranslational modifications that induce neuroinflammation. We aim to clarify some of the principles of neuronglia interactions in the developing brain through these challenging projects.

In silico Drug Discovery and Chemical Biology

HIROKAWA Takatsugu

With the development of increasing number of genome sequence data and protein structure determination, pharmacological and drug discovery research based on the structural biology data have been accelerated. However, some of experimental structural data may be inconvenient to use for drug discovery due to the constraints on crystallization conditions or undesirable biological state. Molecular modeling and simulation can help to bridge the gap between original state of experimental structural data and drug discovery oriented structural models. Structural models from the collaboration between the experimental data and in silico technology will be useful to guide sophisticated drug discovery process. We propose the supporting and developing of in silico drug discovery using molecular modeling and simulation based on fundamental technologies such as homology modeling, docking simulation, molecular dynamics (MD) simulation, chemical biology and cheminformatics.

Molecular mechanism of sleep regulation

International Institute for Integrative Sleep Medicine (WPI- IIIS) Yanagisawa/Funato Laboratory


We spend nearly one –third of our lives asleep. The mechanism and function of sleep, however, remains unclear. Many factors such as mental illness, food, drugs, and emotions, can affect sleep/wake regulation. Disorder of sleep is not only by itself a major problem in modern society, but also an established risk factor for metabolic syndrome and other lifestyle diseases. We discovered the neuropeptide “orexin” that regulates sleep. Over 10 years of orexin research have convinced us that we have to take boldly new approaches to gain fundamental insights on the mechanism of sleep/wake regulation. Our approaches include real-time visualization and manipulation of the activity of multiple neurons within the sleep/wake regulatory circuits in freely behaving mice. We also carry out a large-scale forward genetic screen in mice, looking for new genes directly responsible for sleep/wake regulation.

International Institute for Integrative Sleep Medicine (WPI-IIIS) Lazarus/Oishi Laboratory


The investigative focus of our laboratory is the cellular and synaptic basis by which the brain regulates sleep and wakeful consciousness. Our experiments seek to link the activity of defined sets of neurons with neurobehavioral and electroencephalographic outcomes in behaving animals by using innovative genetically or chemically engineered systems (optogenetics, chemogenetics or optopharmacology) in conjunction with in-vivo imaging (e.g. fiber-optic endomicroscopy). We also employ single-cell or spatial gene expression profiling to understand how the sleep/immune system crosstalk is regulated at cellular and molecular levels. We made key contributions to our understanding of sleep/wake behaviors, for example, why coffee wakes us up, why we fall asleep when bored, or how REM sleep loss increases the desire for junk food.

Neural activity dynamics across sleep-wake cycles

International Institute for Integrative Sleep Medicine (WPI-IIIS) Honjoh Laboratory


Sleep is a universal biological process across organisms with a nervous system. Prolonged wakefulness beyond spontaneous sleep/wake rhythm results in marked cognitive decline, showing that sleep is essential for the maintenance of normal cognitive functions. Although the detrimental effects of sleep loss have been long established, it still remains unclear why the brain cannot sustain waking cognition over a certain duration, and how sleep restores fatigue of the brain. Therefore, to better understand why we need to sleep, we investigate neural activity and gene expression dynamics across the sleepwake cycle. We use mice as an model organism and mainly focus on the thalamocortical system that plays critical roles in cognition.

Brain plasticity during sleep and its application

International Institute for Integrative Sleep Medicine (WPI-IIIS) Sakaguchi Laboratory


As the brain grows, its plasticity shifts from tissue and cells to synapses. In the dentate gyrus of the hippocampus, however, an exceptionally small number of neurons continue to be generated even after brain maturation. We found that these newborn neurons decrease their activity during REM sleep after learning, and surprisingly, a small amount of their activity is required for memory consolidation (Kumar et al., Neuron, 2020). We are currently investigating the mechanisms of memory circuit reorganization based on the cellular plasticity of the adult brain. In addition, we are conducting a clinical study on patients to apply these research results.

We also aim to establish a novel method that evaluates neurobehavioral responses to sleep loss based on an accurate and unobtrusive measure of alertness. These researches will contribute to solving social problems related to sleep as well as understanding how sleep relates to the human mind and behavior.

We all need regular sleep to maintain our brain function. In sleep the brain is still active, but the activity looks very different from waking. We want to find out how the brain produces these different patterns and how they help us to wake up in the morning, refreshed and ready for a new day. For this we study signals from groups of neurons and from individual neurons in mice in waking and sleep, using functional imaging and implanted electrodes. We try to detect patterns that indicate how neurons communicate in waking and sleep. For electro-encephalographic (EEG) recordings from humans and mice we develop novel analytical tools to determine how much a subject is active, how much it needs to sleep, or how good that sleep is.
