Pertussis Toxin Preparation:

Lyophilized pertussis toxin (List Biological) was reconstituted with distilled water. The reconstitute was then further diluted to a concentration of 2500 ng/ml then loaded into 1ml syringes for IP injection (Stromnes and Goverman, 2006).

EAE Induction:

Mice were shaved dorsally from the base of the tail to the middle of the back rostrally. Subcutaneous (SC) injections of MOG35-55/CFA emulsion were performed on day 0 and day 7. Each mouse received 4 subcutaneous (SC) injections of 0.05 ml at separate locations on the rump, yielding a total of 0.2 ml per mouse. Injections sites were arranged rostro-caudally, two on either side of the dorsal midline. A single IP injection 0.1ml of pertussis toxin was administered at a concentration of 2500 ng/ml on day 0 and day 2.

EAE Induction:

Mice (8-12 wk of age) were immunized subcutaneously with 100 µg MOG p35-55 (2 mg/mL in 1x PBS) in an emulsion (volume ratio 1:1) with CFA (2 mg/mL heat-killed Mycobacterium tuberculosis H37Ra; Difco Laboratories) as described previously (225). MOG p35-55 was synthesized by the Stanford Pan Facility (Stanford, CA). Mice were also injected intravenously with 125 ng Bordetella pertussis toxin (List Biological Laboratories) on day 0 and 2 post immunization. Mice were examined daily for clinical signs of EAE for 30 d and were scored on a five-point scale: 0, no clinical disease; 1, limp tail; 2, hindlimb weakness in one or both hindlimbs; 3, complete paralysis in one or both hindlimbs; 4, hindlimb paralysis plus some forelimb weakness; and 5, moribund or dead.
