     Research concerning the evaluation of vaccines and molecular epidemiological investigation

     Distrust in vaccines is derived from their adverse reactions. It is necessary to accurately evaluate whether adverse events after vaccination are related to the vaccine. Many instances reported as adverse events are common infections such as respiratory infections and enterovirus infection. Therefore, molecular epidemiological investigations are necessary to understand the pathology and epidemiology of common infections and the properties of wild epidemic strains for using live attenuated measles, mumps, and rubella vaccines. The basic laboratory procedures for RT-PCR, determination of base sequences, and gene recombination are studied, and research under the following themes is conducted.

(1) Molecular epidemiology of
     measles, mumps, enterovirus, and RS virus
(2) Analysis of the mechanism of the attenuated
(3) Designing recombinant vaccines expressing
(4) Antibody epidemiological investigations of
     measles, rubella, mumps, and influenza
(5) Biological activity of the measles virus
(6) Cell fusion abilities of measles and mumps viruses
(7) Rapid diagnosis of viral infections

     Research concerning the type III secretion machinery of Gram-negative bacteria and effector functions

     Some pathogenic bacteria produce their pathogenicity by actively transporting various pathogenic factors into host cells. Recent studies have revealed that type III secretion machine is involved in this transport of pathogenic factors into host cells. The special research of molecular bacteriology is conducted by focusing on the mechanisms contributing to the pathogenicity of crosstalk of pathogenic bacteria, genome analysis of pathogenic factors, structure and function of type III secretion machinery, and proteins derived from bacteria transported into host cells. After guidance in the basic techniques of molecular biology and molecular cell biology over approximately 2 months, students are asked to choose a research theme of interest from the following. Instructors serve as guides and assist the students to reach their individual research goals, respect the autonomy of students, provide logistic support for the evaluation of results, and determine the direction of the development of research. To promote improvements in research presentation techniques, research presentation sessions are also held using a projector and other equipment to develop human resources capable of independently pursuing an academic career after the completion of the masterfs course.

(1) Functional analysis of effectors that are
     transported into host cells by
     type III secretion machinery
(2) Functional analysis of the type III
     secretion machinery
(3) Analysis of interactions between effectors and
     host factors
