CSF and blood samples were analyzed in the centralized CSF laboratory of the University Clinic Münster within 1 h of sample taking. Standardized mFC of CSF and blood samples using a predefined staining panel are routinely performed at our center of all CSF samples collected during regular working hours. Analysis was performed once per sample.
Samples were centrifuged for 15 min at 300 ×
g, supernatant was removed, and staining was performed based on an established protocol [37 (
link)]. The following antibodies were used: CD3 (UCHT1); CD4 (13B8.2); CD8 (B9.11); CD14 (RMO52); CD16 (3G8); CD19 (J3–119); CD45 (J.33); CD56 (C218); CD138 (B-A38); HLA-DR (Immu-357) (all Beckman Coulter, clones in brackets). Gating was performed on forward scatter and sideward scatter and afterward on CD45+ cells. Percentage of cell population was analyzed as described before [30 (

Navious flow cytometer (Beckmann Coulter) and the software
Kaluza (version 2.1).
