We expect that our studies will help us to understand the mechanisms underlying diseases including birth abnormality, neuropsychiatric disorders, and immune disorders, giving us a new window into therapeutic strategies for nerve injury, Alzheimer’s disease, neuropsychiatric disorders, and cancer metastasis. We recently reported “Grip & Slip mechanism” for axon guidance; this mechanism is disrupted in a human patient of L1-CAM/CRASH syndrome, suffering corpus callosum agenesis and corticospinal tract hypoplasia. We are also currently analyzing the molecular mechanisms for immune cell migration and tumor cell metastasis.
