Quantitative assessment of CSF biomarkers by ELISA. A-F Levels of S100B, NfL, Ab40, Ab42, P-tau and T-tau in the human CSF samples, n = 46. The right part of the graphs represents the difference between the ventricular and the lumbar CSF concentrations in each patient. H–L Same biomarkers as in A–F quantified on porcine CSF samples, n = 18. The data were evaluated for statistical significance with Wilcoxon signed rank test. *P < 0.05, ***P < 0.001, ****P < 0.0001
