Levels of a CXCL8, b CXCL9, and c CXCL10 in CSF of HSE (n = 14) and HSM (n = 20) patients compared to healthy controls (n = 33) and to serum (n = 8/group; control = 5). Data are presented as individual values with medians indicated by horizontal bars. CSF comparisons were performed using Kruskal-Wallis’ non-parametric test with Dunn’s post-test. White symbols are non-matched CSF or serum samples, which were excluded from analysis of paired CSF and serum (filled symbols), using Wilcoxon matched-pairs signed-rank test. Statistical analysis was performed using GraphPad Prism version 6 (GraphPad Software). Abbreviations: CSF cerebrospinal fluid, HSE herpes simplex encephalitis, HSM herpes simplex meningitis
