The role for IL-10 in the immunopathogenesis of acute toxoplasmosis
following peroral infection was examined in both genetically
susceptible C57BL/6 and resistant BALB/c mice. C57BL/6-background
IL-10-targeted mutant (IL-10-/-) mice all died in 2 wk
after infection with 20 cysts of the ME49 strain, whereas only 20% of
control mice succumbed. Histological studies revealed necrosis in the
small and large intestines and livers of infected
IL-10-/- mice. The necrosis in the small intestine was
the most severe pathologic response and was not observed in control
mice. Treatment of infected IL-10-/- mice with either
anti-CD4 or anti-IFN-
mAb prevented intestinal pathology and
significantly prolonged time to death. Treatment of these animals with
anti-IL-12 mAb also prevented the pathology. Significantly greater
amounts of IFN-
mRNA were detected in the lamina propria lymphocytes
obtained from the small intestine of infected IL-10-/-
mice than those from infected control mice. In common with
C57BL/6-background IL-10-/- mice, BALB/c-background
IL-10-/- mice all died developing intestinal pathology
after infection. Control BALB/c mice all survived even after infection
with 100 cysts and did not develop the intestinal lesions. Treatment
with anti-IFN-
mAb prevented the pathology and prolonged time to
death of the infected IL-10-/- mice. These results
strongly suggest that IL-10 plays a critical role in down-regulating
IFN-
production in the small intestine following sublethal peroral
infection with Toxoplasma gondii and that this
down-regulatory effect of IL-10 is required for prevention of
development of IFN-
-mediated intestinal pathology and mortality in
both genetically resistant BALB/c and susceptible C57BL/6
mice.
