| Outline of Final Research Achievements |
Our research goal was to clone the gene that transforms Caco-2 cells into M cells, which transcytose antigenic molecules in the intestinal lumen to subepithelial immune cells, by employing the Caco-2/Raji cells co-culture system. Furthermore, we aimed to establish monoclonal antibodies recognizing the gene products to clarify changes in the number and distribution of M cells in inflammatory bowel diseases. However, due to the difficulty to obtain the optimal condition for the induction of M cell phenotype, we changed the strategy. We tried to establish monoclonal antibodies against GP2 and Spi-B, both of which are found to be markers for mouse M cells. We have not yet obtained the hybridoma, and currently, we are preparing obtaining optimal condition for hybridoma screening.
