The effect of a dexamethasone and a FK506 on the induction of chemokines in human mast cells

ABSTRACT: Mast cells produce a large amount of several chemokines after cross-linking of FceRI and participate in the pathogenesis of allergic diseases. The objective of this study was to comprehensively investigate FceRI-mediated chemokine induction in human mast cells and the effect of a corticosteroid (dexamethasone) and a calcineurin inhibitor (FK506). Human peripheral blood-derived mast cells were stimulated with anti-IgE antibody in the presence of dexamethasone or FK506. Expression of eight chemokines was significantly induced in mast cells by anti-IgE stimulation. Induction of CCL2, CCL7, CXCL3 and CXCL8 by anti-IgE was significantly inhibited by dexamethasone. In contrast, induction of CCL1, CCL3, CCL4 and CCL18 was significantly inhibited by FK506. Combination of dexamethasone and FK506 su
