Figure 6From: Plumbagin Protects Mice from Lethal Sepsis by Modulating Immunometabolism Upstream of PKM2Delayed treatment with plumbagin protects mice from sepsis. (A) The cecal ligation and puncture (CLP) technique was used to induce intraabdominal sepsis in mice (n = 20/group). Repeated administration of plumbagin (4 mg/kg) at 24, 48, and 72 h after CLP significantly increased survival compared with vehicle group (*, p < 0.05), as measured by Kaplan-Meier test. (B-G) In parallel experiments, serum levels of lactate (B), IL-1β (F), HMGB1 (C) and PKM2 mRNA (D), NOX activity (E) and ECAR (G) in isolated peritoneal macrophages at indicated time points were measured (n = 3–5 animals/group, values are mean ± SEM, *, p < 0.05).Back to article page
