| Outline of Final Research Achievements |
① In the current study, involvement of the transcription factors, PU.1, GATA1 and GATA2 in the expression of allergy related genes in mast cells was analyzed. It was revealed that knockdown of PU.1 or GATA2 decreased FcεRI expression and suppressed the IgE-mediated activation of mast cells. In addition, Syk was identified as a new target gene of PU.1. ② We found that Tannic acid decreased surface FcεRI expression via silencing of GATA2. Moreover, oral administration of Tannic acid inhibited IgE/Ag-induced passive systemic anaphylaxis. Collectively, these results demonstrate that transcription factors that regulate mast cell-specific gene expression are targets for prevention of mast cell-mediated allergic diseases and that food ingredients could be an effective tool.
