IL6 and Sepsis: Serum samples of sepsis patients (as compared to non-septic patients) contained higher neutrophil counts (13.3 × 109 vs. 6.5 × 109 cells/l; Figure 6A, left panel) and higher concentrations of MPO (13.1 vs. 8.8 ng protein/mL; Figure 6A, right panel), IL-6 (188 vs. 23 pg/mL; Figure 6B), and TNFα (348 vs. 63 pg/mL).
