STAT1 and infection: After infection of wild-type mice with P. chabaudi the Stat1-dependent chemokines CXCL10 (IP-10), CCL2 (MCP-1) and CCL7 (MCP-3) reached relative serum peak levels by day 7 after infection with the notable exception of CCL2 which was the most abundant in the circulation already at day 4 (Figure 5A).
