Similar levels of immune soluble factors in the cerebrospinal fluid (CSF) of patients with primary progressive multiple sclerosis (PP-MS) and secondary progressive multiple sclerosis (SP-MS). The levels of interleukin (IL)-1ra, IL-9, IL-15, interferon (IFN)-γ, tumor necrosis factor (TNF)-α, IL-8, interferon-gamma induced protein (IP)-10, monocyte chemoattractant protein (MCP)-1, macrophage inflammatory protein (MIP)-1α, MIP-1β, regulated on the activation, normal T cell expressed and secreted (RANTES), eotaxin, and vascular endothelial growth factor (VEGF) were simultaneously measured in the CSF of PP-MS and SP-MS by multiplex assay. Each CSF sample was analyzed in duplicate and means are represented. Data are reported as mean ± SEM.
