A) Heatmap of plasma cytokines in IgG- and αNK1.1-treated CLP50 hosts prior to surgery and at 6, 12, 24, and 48hrs post-surgery. Plasma (B) IL-6, (C) IFNγ, and (D) IL-1β concentration at 6 and 12 hrs after surgery in Sham and CLP50 mice that received either control IgG or αNK1.1 depleting antibody. Plasma cytokine data are from a single experiment with 3 mice per group. * = p<0.05. Error bars represent standard error of the mean.
