Molecular Oral Physiology

The Department of Molecular Oral Physiology is conducting the research and education of postgraduate and undergraduate students under the direction/support by 5 staff members (4 faculties and 1 technical officials). In the laboratory, we have 3-4 graduate students and 1-2 visiting research fellows joining our group. The laboratory is international as many of research fellows/students are from abroad. Members work friendly and each person conducts his/her projects in cooperation with others. The properly functioning salivary gland (in terms of secretory activity) and an effective defense system in the oral cavity are important for maintenance of oral health. We are conducting the following projects under this concept.
