IL10 and infection: Surprisingly, at later time points after infection, macrophage/neutrophil-specific IL-10-deficient mice had slightly higher parasite loads than IL-10-competent mice, while complete IL-10-deficient mice had somewhat higher parasite loads than the T cell-specific IL-10-deficient mice on both the C57BL/6 and the BALB/c background, although these differences never reached statistical significance.
