Supplementary Figure legends
Supplementary Figure 1 . Admission levels of soluble CXCL16 in
serum samples from septic patients without bacteremia and with
documented bacteremia
Supplementary Figure 2 . CXCL16 production was elevated in
septic mice after cecal ligation puncture (CLP). C57BL/6 mice (n = 5 per
group) were subjected to sham or nonsevere CLP with a 24-gauge needle,
and then samples were collected for CXCL16 quantification by ELISA.p <0.001 when compared with sham control mice
(Mann-Whitney U test).
Supplementary Figure 3 . The effects of recombinant murine
CXCL16 on bacterial clearance in cecal ligation and puncture
(CLP)-induced nonsevere sepsis. Dilutions of peritoneal lavage fluid
(PLF) and blood were collected from CLP mice (n = 6) administered with
or without recombinant murine CXCL16 (0.5 μg), and then were cultured on
blood agar plates, and the number of bacterial colonies was determined
as colony-forming unit (CFU).
Supplementary Figure 4 . Administration with anti-CXCL16
antibody did not affect bacterial clearance in CLP-induced severe
sepsis. Dilutions of peritoneal lavage fluid (PLF) and blood were
collected from CLP mice (n = 6) treated with or without anti-CXCL16
antibody (10 μg), and then were cultured on blood agar plates, and the
number of bacterial colonies was determined as colony-forming unit
(CFU).
