EAE induction
Various groups of mice at 8-12 weeks were subcutaneously (s.c.) injected over four sites in the flank with 100 μL of emulsified IFA supplemented with 200 μg of MOG33–55 and 500 μg of heat-killed M.tb as previously described (Ouyang et al., 2019; Xiao et al., 2015). Three hundred ng pertussis toxin (List) per mouse in PBS was injected intraperitoneally (i.p.) at the time of immunization and 48 h later.

Immunoblotting and pull-down assays

Cell lysates and cell culture supernatants were separated by 10% or 15% SDS-polyacrylamide gel electrophoresis under reducing conditions (non-reducing when using the antibody against C5), transferred to a nitrocellulose membrane and blocked with 5% non-fat dry milk in 0.1% Tween 20/TBS solution. The membranes were probed with primary goat antibodies against PA (1:5000, List Biological Laboratories), …

Mouse Model of EAE

Female mice at 6 to 8 wk of age were immunized subcutaneously with 50 to 100 μg of MOG35-55 peptide (MEVGWYRS PFSRVVHLYRNGK; GL Biochem) emulsified in complete Freund’s adjuvant (Sigma) and supplemented with 400 to 800 μg of Mycobacterium tuberculosis H37Ra (Difco). The mice were intraperitoneally injected with pertussis toxin (200 ng/mouse; List Biological Labs) in 100-μL phosphate-buffered saline (PBS) on the same day and 2 d later. …

Cuprizone, EAE, and pertussis toxin injections

Experimental autoimmune encephalomyelitis (EAE) was induced as previously described [56,57,58]. Briefly, emulsion of equal volumes of CFA and 100 µg myelin oligodendrocyte glycoprotein peptide (MOG35–55, MEVGWYRSPFSRVVHLYRNGK) supplemented with M. tuberculosis H37Ra (5 mg/mL, Difco, Detroit, MI) were injected subcutaneously in the scapular region of each mouse. MOG–CFA mixture was emulsified by sonication using a sonic dismembrator (Fisherbrand; FB705). Pertussis toxin (200 ng/mouse, i.p.; List Biological Laboratories) was injected on the days 0 and 2 relative to immunization. …
