MMP levels in serum from patients with VZV CNS infections. Serum levels of MMP2 (a), MMP3 (b), MMP8 (c), MMP9 (d), and MMP12 (e) were compared in VZV patients with different CNS disease manifestations: encephalitis (n = 11), meningitis (n = 14), and Ramsay Hunt syndrome (n = 9) and in uninfected controls (n = 14). Data are presented as individual values with medians indicated by horizontal bars. Comparisons were performed using Kruskal-Wallis’ non-parametric test with Dunn’s post-test. ***p < 0.001, **p < 0.01, *p < 0.05
