Induction of EAE:

Induction of MOG EAE was done as previously described.[29, 30] Shortly, 8 to 9-week-old female C57BL/6 mice were immunized with an emulsion containing 300 µg of MOG35-55 in phosphate-buffered saline and an equal volume of complete Freund’s adjuvant containing 5 mg/mL H37RA (Difco Laboratories, Detroit, MI). The inoculum (0.2 mL) was injected subcutaneously into the left flank. One hundred nanograms of pertussis toxin (List Biological Labs, Campbell, CA) in 0.1 mL phosphate-buffered saline was also injected i.p. on day 0 and 48 h later. …

• Product #179A – Pertussis Toxin from B. pertussis (in Glycerol)

EAE:

Pertussis toxin (200 ng per mouse; List Biological Laboratories, Campbell, CA, USA) was injected intraperitoneally on the day of immunization (day 0) and again 2 days later. Mice were monitored daily for clinical signs and scored as follows: 0, no disease; 1, tail paralysis; 2, paraparesis; 3, paraplegia; 4, paraplegia with forelimb weakness or paralysis; 5, moribund or dead animals.

Induction of EAE:

CNS inflammation was induced using a well-established model of EAE…In brief, groups of 10-wk-old age- and sex-matched mice were s.c. injected in the flank with 100 mg MOG₃₅₅₅ peptide (Genemed)… The same day and 2 d later, 200 ng pertussis toxin (List Biological Labs) in 200 µl physiological saline was injected i.v.

For Foxp3^DTR/+ mice, 8-wk-old females were injected i.p. on days 10, 7, and 4 with 500 ng diphtheria toxin (List Biological Labs). Then EAE was induced as described above.

Animals. Induction and treatment of EAE:

…C57BL/6 mice were bred and maintained in the facilities of the Forschungsinstitut fr Experimentelle Medizin (FEM, CharitUniversittsmedizin, Berlin, Germany), under specific pathogen-free (SPF) conditions. EAE was induced as described previously… 200 ng of Bordetella pertussis toxin (List Biological Laboratories, Campell, CA) was administered intraperitoneally at day 0 and 2. EAE experiments were carried out in our animal facilities under standard husbandry conditions. …

Conditioning and Dorsal Column Lesions:

The right sciatic nerve of both WT and MT-I/II-deficient mice (n = 6 for both groups) was lesioned. 7 days later under isoflurane anesthesia, a laminectomy was performed at the T89 level, and the dorsal column was transected to a depth of 1 mm. Another set of WT and MT-I/II-deficient mice (n = 6 for both groups) received only dorsal column lesions. At 5 weeks after surgery, 2 l of 1% cholera toxin B (CTB; List Biological) was injected into the right sciatic nerve, and the animals were transcardially perfused with 4% (PFA) 3 days later. Spinal cord sections were immunostained using goat anti-CTB antibody (1:2000; List Biological), …
