| Research Abstract |
1) RelA, which is a main molecule of NF-kBs, is not involved in antigen-mediated degranulation from mast cells, but plays an important role in pro-inflammatory cytokine production leading to late phase allergic reaction. 2) STAT4 is essential for IFN-β-induced MCP-1 expression in mast cells. Because mast cells are distributed in almost all tissues, our results suggest that mast cells may be involved in the enhancement of the antiviral responses initiated by pDC by producing MCP-1 in response to type I IFNs-STAT4 signals.
