Control and KO mice were injected with LPS (15 mg/Kg). 12 hours after injection blood was collected through cardiac puncture. Serum was sent to a commercial facility (Quansys Biosciences, Utah, USA) and subjected to cytokine/chemokine ELISA array for IL-1β, IL-6, MCP-1, MIP-1α, RANTES and KC. Results are mean ± s.d, paired two-tailed Student’s t-test. n and P values for each are on the top of the figure.
