CCR2 and infection: In WT but not in CCR2 KO mice this treatment mimicked the phenotype observed in IL-10 KO mice [8], killing the mice at 11±1 days post infection with increased liver injury (serum ALT levels: 810±68 versus 223±39 U/ml in anti-IL-10R and control antibody treated WT mice at day 10 post infection).
