Effect of Der p 1 on CD83 expression by DCs.

Monocyte-derived DCs from house dust mite–sensitive patients (left panels) and from healthy donors (right panels) were exposed or not to Der p 1 or LPS for 24 hours. DCs were incubated with PE-conjugated anti-CD83 mAbs and analyzed for CD83 expression (filled histograms). Open histograms represent fluorochrome-matched isotype control mAbs. One representative experiment of 3 is shown.
