ABSTRACT
Chemokine CXC motif ligand 16 (CXCL16) is an important mediator that has been shown to participate in various human diseases. The role of CXCL16 in the immunopathology of sepsis remains unidentified. In this study, we found that human patients with sepsis had significantly higher soluble levels of serum CXCL16 than healthy volunteers on day of intensive care unit (ICU) admission. Soluble CXCL16 remained significantly up-regulated in the patients with sepsis, which correlated with disease severity. Furthermore, nonsurvivors displayed significantly higher admission levels of soluble CXCL16 compared with survivors of septic patients. Soluble CXCL16 levels revealed significant prognostic value for 28-day mortality, and CXCL16 was shown to be an independent predictor of 28-day mortality in the patients with sepsis. In a murine model of cecal ligation and puncture (CLP)-induced nonsevere sepsis, supplementation of recombinant CXCL16 protein could increase sepsis-induced mortality and tissue injury. Conversely, neutralizing CXCL16 by anti-CXCL16 monoclonal antibody could decrease mortality and tissue injury in CLP-induced severe sepsis. However, CXCL16 did not affect the ability of these mice to clear bacteria in CLP. Taken together, CXCL16 could be related to sepsis not only as a novel biomarker of prognosis, but also as a potential target for therapeutic intervention.
