2.3 Induction of antibody-augmented MOG35-55 EAE

Active EAE was induced in 8-10 weeks old mice. MOG peptide 35-55 (MOG35-55, 100 µg; Institute of Medical Immunology, Charité Berlin, Germany) emulsified in complete Freund’s adjuvant (CFA) was injected subcutaneously (s.c.) under anesthesia (50 mg/kg Ketamine; Ketanest®, Zurich, Switzerland and 1 mg/kg medetomidine; Dormitor®, Provet, Lyssach, Switzerland). After 30 minutes, mice were awakened by a s.c. antagonist injection (Atipamezol 1.25 mg/kg; Antisedan®, Provet), hydrated with 300 µl sodium chloride 0.9% solution and observed until fully recovered. Zero and two days post immunization (dpi), 200 ng pertussis toxin (List Biological Laboratories, Campbell, CA, USA) was injected intraperitoneally (i.p.). …

EAE induction
8-week-old, female C57BL/6 mice were s.c. injected with MOG35–55 peptides (300 mg per mouse) emulsified in complete Freund’s adjuvant (CFA) (200 μL per mouse) containing dead Mycobacterium tuberculosis (1 mg per mouse) on day 0. On days 0 and 2, pertussis toxin (400 ng per mouse) was intraperitoneally injected into mice. …

Active EAE model

EAE was induced by immunizing C57BL/6J mice with myelin oligodendrocyte glycoprotein (MOG)35-55 peptide (100 μg per mouse, ANASPEC, 60130-5) and complete Freund’s adjuvant (CFA) containing 4 mg ml−1 (0.4 mg per mouse) of heat-killed Mycobacterium tuberculosis (Chondrex, 7001)24. Mice were intraperitoneally injected with pertussis toxin (PTX, 250 ng/mouse, List Biological Laboratories, 180) on days 0 and 2. PBS or ITA (50 mg kg−1) was intraperitoneally injected every other day from day 0 to day 14. An ITA solution was adjusted to pH 7.4 with 1 N NaOH at 37 °C. …

4.5. EAE Induction and Clinical Evaluation of Experimental Mice

Mice were divided in a random manner into four groups (six mice in each group), including: group 1: naïve, untreated control mice; group 2: MCP-immunized EAE mice; group 3: MCP was immunized and BEY was administered from day 3 to day 27; group 4: BEY orally administered to mice from day 3 to day 27 of experiment. Mice were immunized with MOG35–55 (100 μg; Peptide International) emulsified in complete Freund’s adjuvant (CFA; Sigma-Aldrich, St Louis, MO, USA) containing 10 mg/mL heat-killed Mycobacterium tuberculosis H37Ra (Difco Laboratories, Detroit, MI). The mice were injected intraperitoneally with pertussis toxin (PTX) (List Biological Laboratories, Detroit, MI; 500 ng) on days 0 and 2. A total of 200 µL of emulsion (MCP) was administered subcutaneously on mice’s flanks at four locations. …

2.2. Surgery

Under isoflurane anesthesia, 1.0 µl of a 1 % solution of the retrograde neuronal tract tracer cholera toxin B subunit (CTb; Lot #10331A1; List Biological Laboratories, Inc., Campbell, CA) was unilaterally deposited into the basal forebrain (n = 6–8/group) using the following stereotaxic coordinates, relative to Bregma [16]: anterior (AP) −0.8 mm, lateral (L) +/- 2.5 mm, ventral (DV) –8.0 mm (from skull surface). Left and right hemispheres were equally represented. CTb was pressure injected over a 10 min interval (0.1 µl/min) and the needle remained in place for an additional 10 min post-infusion to allow diffusion away from the needle tract. Animals whose CTb deposits were not centered in the VP/SI, based on post-mortem immunohistological labeling, were excluded from analysis. Prophylactic buprenorphine (0.02 mg/kg, s.c.; Med-Vet International, Mettawa, IL) was given at the conclusion of surgery to minimize post-operative pain during emergence from anesthesia. Animals were allowed one week recovery from surgery, while handling, habituation, and food intake measurement continued.
