IL10 and infection: While, as expected, both IL-10 treated and untreated infected mice exhibited significant increases in neuropathology, those treated with systemic IL-10 from day 17 of infection exhibited a significantly lower neuropathological grade (3.34±0.08) compared to untreated infected mice (3.87 ± 0.17, mean ± SE, p<0.05 Tukey post-hoc test).
