2.2. Experimental autoimmune encephalomyelitis (EAE) induction

6–7 weeks old C57BL/6 female mice were immunized with an emulsion containing 200 μg of purified myelin oligodendrocyte glycoprotein peptide (MOG35–55) in normal saline (0.9% NaCl) and an equal volume of complete Freund adjuvant (Betcon, Dctinson and company, sparks MD, 21152 USA). 0.1 ml volume of the inoculum was injected subcutaneously (S·C) on day 0 into each hind limb. 200 ng pertussis toxin (List biological laboratories INC) was diluted in 0.1 ml normal saline (0.9% NaCl) and was injected I·P immediately after S·C injection of MOG35–55 emulsion and 48 h later. …

Serological analysis of B. pertussis-specific antibodies

On the day of mouse processing (euthanasia and dissection), a cardiac puncture was performed on each mouse. Approximately 1 mL of blood was removed from each mouse. The samples were placed into serum separator tubes (Cat. Number: 365967; BD) centrifuged for 2 min at 14,000 × g. Serum was collected and stored at −80°C until analyses were performed. Serological responses specific to B. pertussis antigens were quantified by enzyme-linked immunosorbent assay (ELISA). High-binding microtiter plates were coated with pertussis toxin (PT) (50 ng/well) (PT#180, LIST Biologicals), filamentous hemagglutinin (FHA) (50 ng/well) (Enzo Life Sciences), or PRN (50 ng/well) (PRN#187, LIST Biologicals) as described in Boehm et al. (34). …

Cell Culture

MCF-10A cells were cultured in Dulbecco’s modified Eagle’s medium (DMEM)- F12 (Welgene, LM002-04) supplemented with 5% horse serum (Invitrogen, 26050-088), epidermal growth factor (Peprotech, AF-100-15) at 20 ng/ml, insulin (Gibco, A11382II) at 10 μg/ml, hydrocortisone (Sigma, H0888) at 0.5 μg/ml, and cholera toxin (List Biological Laboratories, 100B) at 100 ng/ml. HEK293T, MDCK, HFE-145 (gastric epithelial) cells and PANC-1 (pancreatic adenocarcinoma) cells were cultured in DMEM medium supplemented with 10% fetal bovine serum (FBS) (Gibco, 12483020). AGS, MKN-45 (both from gastric adenocarcinoma), and BCPAP (thyroid carcinoma) were cultured in RPMI medium supplemented with 10% FBS.

… The mice were s.c. immunized with 100 µg of MOG (Sigma-Aldrich) emulsified in CFA (BD, Sparks, MD) plus 500 µg of Mycobacterium tuberculosis H37Ra (BD). At the times of immunization and 2 d later, the mice were i.v. injected with 400 ng of pertussis toxin (List Biological Laboratories). Disease severity of EAE was monitored using the criteria as previously described (26). …

Induction and scoring of Experimental Autoimmune Encephalomyelitis (EAE) mice

Female mice were subcutaneously injected with an emulsion of 50 μg myelin oligodendrocyte glycoprotein (MOG) amino acids 35-55 (Sheldon Biotech, Montreal, QC) peptide in incomplete Freund’s adjuvant (Sigma) supplemented with 1 mg of mycobacterium tuberculosis (CFA) (Difco). 400 ng of pertussis toxin (List Biologicals) was administered intraperitoneally on days 0 and 2 post-immunization. For ligand treatment, 40 μg of purified protein was administered intravenously once every three days for the duration of the experiments. …

EAE induction

EAE was induced in mice by subcutaneous injection of 200 μg MOG35–55 peptide with 500 μg M. tuberculosis strain H37Ra (Difco) emulsified in incomplete Freund Adjuvant oil in 200ul volume into the flanks at two different sites. In addition, the mice received 400 ng pertussis toxin (PTX; List Biological Laboratories) i.p. at the time of immunization and 48 h later. …
