CpG oligodeoxynucleotide protection in polymicrobial sepsis is dependent on interleukin-17.

CpG oligodeoxynucleotides (ODNs) may prevent mortality from infection. We have identified a therapeutic benefit in treating sepsis with phosphorothioate ODN sequences containing the CpG motif. Sepsis was induced in rats by cecal ligation and puncture (CLP), and treatment with CpG ODNs reduced sepsis mortality from 80% to 15% during a 108-h period.
