| Outline of Final Research Achievements |
The novel system for visualization and dynamics analysis of holistic antibody repertoire space, that is generated by V(D)J-rearrangement forming the diversity of antigen recognition, by exhaustive RNA sequencing was successfully established.
The process of mouse antibody repertoire development, the response dynamics of antibody repertoire on antigen stimulation, the expression of important antibody molecules through gene-synthesis and reverse genetics, and the role of pre-B cell receptor on the repertoire formation were examined by the new system and the several important findings were obtained.
This novel analysis system is applicable for the development of antibody drugs against newly emerging infectious diseases and for planning the vaccine developments.
