EAE induction:

EAE was induced in C57BL/6 mice by subcutaneous challenge with 200 µg MOG₃₅₅₅ (Peptides International, Louisville, KY) in 200 µL of complete Freund’s adjuvant (Sigma-Aldrich, St. Louis, MO). On days 0 and 2 postchallenge, mice received 400 ng of Bordetella pertussis toxin intraperitoneally (List Biological Laboratories, Campbell, CA). Mice were monitored and scored daily for disease progression as previously shown.

Animals and Induction and evaluation of EAE:

EAE was induced in male and female B6 and PWD mice as follows. Mice were injected subcutaneously with 0.1 ml of emulsion containing 2.5 mg of MSCH in PBS and 50% CFA (Sigma, USA) on day 0 and day 7. CFA was supplemented with 4 mg/ml Mycobacterium tuberculosis H37Ra (Difco, USA). On day 0 and day 2 mice also received an i.p. injection of 200 ng pertussis toxin (List Laboratories, USA) as an ancillary adjuvant. …
