Figure 3RRV infection results in Th1 polarization of hepatic lymphocytes. Hepatic cell surface staining by flow cytometry for CD3 (
A) and CD19 (
B) shows that the lymphocytic infiltrate in portal tracts is predominantly composed of CD3
+ cells beginning 7 days after RRV inoculation. CD3
+ cells also showed staining with CD4
+ (
C) or CD8
+ (
D). (
E) Functional polarization of T lymphocytes is demonstrated 7 days after RRV challenge by an increase in mRNA expression for IFN-γ and IL-12p40. (
F) The mRNA expression for Th2 cytokines also increases above the levels of controls at 7 and 14 days, but at lower levels when compared with Th1 cytokines. *
P < 0.05 when the RRV group is compared with controls;
n = 4–7 mice per group at each time point. NS, normal saline.
