GRK5 wild type and knockout mice were subjected to CLP surgery and peritoneal (A) and plasma (B) fluids collected 12 hours after surgery as described in the methods. IL-6, IL-10, TNFα, IL12/23 (total p40), and MCP-1 were measured in these two fluid samples using ELISA kits from eBiosciences. (N=12 for wild type and N=9 for knockouts for the 12 hour timepoint).*P<0.05, **P<0.01 and ***P<0.001 compared to the corresponding septic wild type groups.
