<i>L. mexicana</i> promastigotes alter the cytokine production profile of DCs.

<p>(<b>A</b>) DC2.4 cells were infected with <i>L. mexicana</i> and then stimulated for 8 hrs with LPS. mRNA was extracted and IL-12 mRNA expression was analyzed by RT-PCR. (*) denotes P<0.05 between specific groups. Data pooled from three experiments is shown. (<b>B–D</b>) Primary BMDCs were infected with <i>L. mexicana</i> or left in media for 6 hrs, with or without LPS (100 ng/mL) ON. Levels of secreted IL-12p40, IL-12p70, and IL-10 were measured by ELISA. One representative experiment of three is shown.
