Concentrations of pro-inflammatory cytokines (A) IL-6 and (B) IFN-γ from the cell culture supernatant. Splenocytes were isolated from the spleens of MOG-induced EAE mice on day 30. The three different groups consisted of PBS-, MOG-BPI-, or MVBMOG/PLP- treated mice on days 4, 7, and 10. The pooled splenocytes (n = 3 mice) were stimulated in vitro with PLP139-151, and supernatant was isolated 72 hours later for cytokine detection (*p < 0.01).
