Research Abstract |
In this study, we tried to elucidate the functions of intestinal immune cells, focusing on their responses to microbes and microbial components, in relation to development of novel immunomodulating functional foods. We examined the suppressive response of Peyer's patch dendritic cells to multiple TLR simulation. We analyzed CD3-IL-2R+ cells, and found that they were also present in the lungs, and that they responded to influenza virus infection. We also examined gene expression of regulatory T cells induced in oral tolerance. Furthermore, we examined the mechanism of IgA induction by Bacteroides.
