Induction and evaluation of active EAE

For the construction of chimeric mice, Rag2-/- mice were adoptively transferred with 107 wild-type (Wt) T cells, Mid1-/- T cells, or a mixture of CD45.1-expressing Wt and CD45.2-expressing Mid1-/- T cells at a 1:1 ratio. Wt, Mid1-/-, or chimeric mice were then used for the induction of active EAE as previously reported 25. Briefly, mice were subcutaneously injected with a 200 μL emulsion that contains 1 mg/ml MOG35-55 peptide (MEVGWYRSPFSRVVHLYRNGK), 2.5 mg/ml Mycobacteria tuberculosis H37Ra (B.D.), and 100 μL Freund’s adjuvant (Sigma). On the day of immunization and two days after immunization, mice were intraperitoneally injected with 200 ng of pertussis toxin (List Biological Laboratories Inc.).

Sample collection

Subjects underwent a first bronchoscopy (28 ± 2 days after placebo treatment) to collect pre-challenge baseline BAL from a segment of the left lower lobe using 100 mL of pre-warmed saline. Two baseline mucosal biopsies from the anterior segment of the left lower lobe and the right lower lobe were sampled. Segmental challenge with LPS (40 endotoxin units per kg body weight diluted in 10 mL of saline; endotoxin from E. coli Type O113; List Biological Laboratories Inc., Campbell, California, USA) was performed in the medial segment of the middle lobe and 10 mL saline (0.9%) was applied in the medial segment of the lingula as control. …

Induction of EAE

Experimental animals were subcutaneously injected with 200 μL of myelin oligodendrocyte glycoprotein35-55 (MOG) peptide at 1 mg/mL (Koma Biotech, Seoul, Korea) emulsified in complete Freund’s adjuvant (CFA; Sigma-Aldrich, St. Louis, MO, USA) supplemented with Mycobacterium tuberculosis H37Ra (5 mg/mL; Difco Laboratories, Franklin Lakes, NJ, USA). All mice were injected intraperitoneally with 500 ng of pertussis toxin (List Biological Laboratories, Campbell, CA, USA) on the day of induction and again 2 days later. After immunization, all mice were weighed and observed daily for clinical signs of EAE, …

Adjuvant-immunized EAE and ESS mouse model

The induction of EAE was described in our previous studies.77,78 Briefly, female C57/BL6 mice at 8 weeks of age were induced by
subcutaneous immunization in the back region with 200 mg of the MOG35-55 peptide (MEVGWYRSPFSRVVHLYRNGK, GL Biochem)
in complete Freund’s adjuvant (CFA, Chondrex) containing 20 mg/mL Mycobacterium tuberculosis H37Ra (BD difco). At 2 h and 48 h
postimmunization, 200 mg doses of pertussis toxin (List Biological Laboratories) were diluted in PBS and intravenously injected into EAE model mice.
