A number of studies clearly indicated that genetic backgrounds largely contribute to the pathogenesis of epilepsy and neurodevelopmental disorders, and actually recent developments of techniques in molecular genetics have identified a number of genes responsible for those diseases. Our research group has been working on the identification of those genes, making of disease model mice and the understanding of disease mechanisms by analyzing those models, and further trying to develop effective therapies including gene therapies to treat such diseases (Yamakawa group). We are also studying rheumatoid arthritis interstitial pneumonia (Kanazawa group).

Thicker and thinner lines indicate increased and decreased neural transmissions, respectively. (Miyamoto H et al, Nat Commun 2019)
