Analysis of CD83 and CD80 surface expression in time.

<p>DCs were treated with NSRmock, NSR, LPS, LPS+NSRmock or LPS+NSR and were harvested at 0, 4, 8,12, 16, 24 and 48 h post treatment. Surface expression of CD83 (upper panels) and CD80 (lower panels) were measured by flow cytometry. Left panels show histograms from one representative experiment. Time points are depicted with different colors and the color code is shown at the right. IC–isotype control. Right panels illustrate average data from three independent experiments with cells from three different donors. Bars represent means ±SD of the fold change of MFI relative to untreated cells.
