Glial and neuronal markers in cerebrospinal fluid in different types of multiple sclerosis

In the present study, CSF concentrations of NFL, t-tau, p-tau, GFAP, S-100B, YKL-40, MCP-1, alpha-sAPP, beta-sAPP, and A beta 38, A beta 40, A beta 42 were measured in 324 MS patients to test whether a correlation among the biomarkers exists and whether the profile of CSF biomarkers varies among the different types of MS. The CSF concentrations of NFL were significantly higher in RRMS while CSF concentrations of GFAP were higher in PPMS. CSF concentrations of NFL correlated with YKL-40 in CIS patients while CSF concentrations of GFAP correlated with YKL-40 in RRMS patients.
