Figure Lengend Snippet: (A-B) DC culture supernatants were tested using a specific ELISA. Error bars represent standard deviation. (A) Soluble ICOSL (sICOSL) was determined in patient (n=16) matched (n=8; iDC and mDC, left) and nonmatched (n=16, right) pairs. Patients were segregated by clinical outcomes, with intergroup significance determined using unpaired (left) or paired (right) Wilcoxon rank sum tests. (B) sICOSL of HD was determined in matched pairs (n=4). (C) KM curves showing OS and PFS in patients (n=15) based on mDC sICOSL. The log-rank p value is indicated. (D) Correlation of mDC sICOSL and Th1 chemokines, MIP-1α and CXCL9 (n=11). The grey shaded area represents the 95% Confidence Interval bands. Correlations were calculated using Pearson’s correlation coefficients. The data was log transformed to meet normality assumptions (right panel). *p≤0.05, **p≤0.01, ns= not significant.
