FIG 11.

Expression of IL-10 and caveolin-1 in livers from MHV3-infected TLR2 KO mice. Groups of 6 TLR2 KO mice were intraperitoneally (i.p.) infected with 1,000 TCID₅₀ of MHV3, and immunolocalization of IL-10 in the livers and ECs of mock- and MHV3-infected TLR2 KO mice was determined by double immunostaining of IL-10 (green) and caveolin-1 (red) at 48 h p.i. Cell nuclei were counterstained with Hoechst stain (blue). In situ expression of IL-10 and caveolin-1 by endothelial cells is indicated by arrows.
