| Research Abstract |
Basophils express major histocompatibility complex class II, CD80, CD86 and produce interleukin 4(IL-4) under various conditions. Basophils, when incubated with IL-3 and antigen or antigen. IgE complexes, internalized, processed and presented antigen as peptide-MHC class II complexes and produced IL-4.Intravenous administration of ovalbumin(OVA)-pulsed basophils into naive mice preferentially induced the development of naive OVA-specific CD4^+T cells into T_H2 cells. Such immunized mice, when challenged by iv administration of OVA, promptly produced OVA-specific IgG1 and IgE. Finally, iv administration of IgE complexes rapidly induced T_H2 cells only in the presence of endogenous basophils, suggesting that basophils are potent antigen-presenting cells that preferentially augment T_H2-IgE responses by capturing IgE complex.
