2.3 Induction and grouping of EAE

Twenty healthy C57BL/6 female mice were randomly divided into four groups: control group (n = 5), EAE model group (n = 5), EAE+BAI treatment
group (n = 5) and the EAE+DEX treatment group (n = 5). The mice were immunized with a mixture of MOG35-55 peptide (200 μg) and CFA, which was
ultrasonically emulsified. On the day of immunization, each EAE mouse received intraperitoneal injections of PTX diluent (0.1 ml, containing 250 ng) on Day 0 and Day 2, while the control mice received an equivalent volume of saline administered intraperitoneally (Figure 1B).
