Activation profile of THP-1 derived dendritic cells stimulated by allergen Mal f 1 beyond its IgE-binding ability

We have shown that rMal f 1 has ideal IgE binding ability and good correlation with binding activity to M. furfur. Moreover, we have revealed a hitherto unknown DC activation profile after rMal f 1 stimulation whereby TNF-α, IL-6, and IL-10 were significantly increased and IL-12 was unaltered, suggesting that rMal f 1 can predispose a DC bias toward the TH22/TH17 pathway beyond the routine IgE-dependent TH2 pathway, thus providing intriguing clues for clinical treatment involving both pathways.
