Animals and EAE induction:

C57BL/6J, 2D2 and Rag1^-/- mice were obtained from the Jackson Laboratories (Bar Harbor ME). IFNAR1^-/- mice (Ifnar1) were obtained from the Mutant Mouse Regional Resource Centers (MMRRC). 2D2 mice [25] were maintained under our established breeding protocol at the CHU de QubecUniversit Laval. Six (6) to 10 week old female mice were used in all experiments. For in vivo T cell transfer, stimulated cells were injected in cold PBS (Cellgro) intravenously, 5 x10⁶ cells per Rag1^-/- recipient. Recipient animals received 200 ng of pertussis toxin (List Biological Labs) intraperitoneally on day 0 (d0) and d2 post-transfer. …
