IL10 and infection: With a few responders in each infection group, the serum concentrations of the cytokines TNF-α and of IL-10 showed significant differences between the groups ≥100 epg and 4–99 epg for TNF-α and between 4–99 epg and <4 epg for IL-10 (p ≤ 0.05) for each comparison, (Figures 3A,B).
