Figure 3.

TNF-α production in PBMC cultures of individuals chronically infected with S. mansoni stimulated in vitro with S. mansoni recombinant proteins in the presence or absence of Polymyxin B. Figure 3A, B and C show TNF-α production in cultures stimulated with rP24, rSm14 and rSm22.6, respectively. Recombinant proteins were used in the concentration of 10 μg/mL and Polymyxin B at final concentration of 30 μg/mL of culture.
