CCL2, CCL5 and CXCL10 production in the ascites fluid of infected mice. Wild type (WT) and CCR5−/− (KO) mice were infected intraperitoneally with T. gondii tachyzoites. CCL2, CCL5 and CXCL10 production in the ascites fluid was measured at 3 and 5 days post-infection (dpi). Each value represents the mean ± the standard deviation of replicate samples (3 dpi, n = 5; 5 dpi, n = 9). RH-GFP (GFP): parasites transfected with GFP alone; RH-OE (OE): parasites transfected with TgCyp18HA and GFP.
