Prof. Uemura, who is a collaborator with us in Nagoya City Hospital, visited Kumamoto to give a seminar provided from HIGO program. He talked mainly about the role of macrophages in diabetic retinopathy. His talk was exciting and attracting all of the audiences, so his topic was discussed beyond the scheduled time. After the seminar, we enjoyed a mixer with Prof. Uemura, which was combined with a new year party of Prof. Minami lab.
