Relative gene expression levels in hDCs determined by quantitative RT-PCR.

<p>RNA was extracted from hDCs after 6 and 20 h of incubation with <i>L</i>. <i>plantarum</i> (in black), <i>L</i>. <i>plantarum</i> + EPM (in dark grey), EPM (in clear grey) or from unstimulated cells (in white) and the expression levels of IL-12p70 gene was calculated relative to the expression levels of the housekeeping gene GAPDH. Error bars represent SEM, n = 3, *** indicates p<0.001 compared with <i>L</i>. <i>plantarum</i> treated samples.
