Production of cytokines by cord and adult blood cells in response to <i>T. cruzi</i> and/or IL-15.

aResults are shown as medians (min-max values) of 8 cord blood samples and 6 adult blood samples. bCord or adult mononuclear cells were culture for 24 h in the presence or not of T. cruzi live trypomastigotes (parasite to cell ratio 1∶1) and/or IL-15 20 ng/mL. *p<0,05 as compared with unstimulated cells (NS), Wilcoxon paired test. #p<0,05 as compared with the effect of IL-15 alone, Wilcoxon paired test. $p<0,05 as compared with cord blood cell response, Mann-Whitney U test.
