GDF15 concentrations in CSF and their relation to CSF cell count and dysfunction of the blood–brain-barrier (BBB). Panel A GDF15 concentrations in CSF are higher in patients with elevated CSF cell count. The Mann-Whitney U test was applied. Panel B GDF15 concentrations in CSF are higher in patients with dysfunction of BBB. The Kruskal-Wallis test was performed.
