rARU quantification

… Purified rARU (List Biological Laboratories, Inc. Campbell, CA) was used as the standard, and assay plates were read on UV/VIS microplate spectrophotometer (SpectraMax190 Molecular Devices, Sunnyvale, CA) at 450 nm and 620 nm.

Oral sensitization experiment

To investigate the oral sensitizing capacity of the two whey products, BN rats (4‐8 weeks of age, only females) were dosed by gavage with 10 mg of either WPI or HT‐WPI together with 20 µg cholera toxin (CT, List Biological Laboratories Inc) in 0.5 mL PBS (n = 12/group). Rats were dosed three times per week (Monday, Wednesday and Friday) for five weeks. Ten days after the last dosing, blood samples were collected from the sublingual vein, converted to serum and stored at −20°C until analysis (overview of animal experimental design in Figure 3A).

Muscle injury model

… Eight-week-old BALB/c mice were immunized three times each, at 1-week intervals, with 200 µL emulsion containing 1 mg myosin and 100 µg complete Freund’s adjuvant (Chondrex Inc., Washington, USA). This emulsion was injected bilaterally into the hock (first immunization), tail base (second immunization), and flanks (third immunization). Pertussis toxin (List Biological Laboratories Inc., California, USA) was injected intraperitoneally (500 ng in 100 µL saline) 1 h after the first immunization. We confirmed the elevation of serum antibody titers against myosin by enzyme-linked immunosorbent assay and by immunohistochemical staining of CD8+ T cells and major histocompatibility complex class I (Supplementary Fig. 1A, B).

EAE induction

Naive CD4 T cells from 2D2 mice were differentiated under Th17 conditions in the presence of vehicle or 2.5 ng/ml oligomycin for 5 days, and 1×106 CD4 T cells were transferred into age- and sex- matched Rag1−/− mice. Recipient mice were injected with 200 ng of pertussis toxin (List Biological Laboratories) intraperitoneally on day 0 and day 2.

EAE

… In case of the semi-therapeutic model, EAE was induced by subcutaneous injection of 100 µg of MOG35-55 antigen (GenScript, Nanjing, China) in complete Freund’s adjuvant emulsion (Chondrex, Redmond, WA, USA). At day 0 and day 2 after immunization, 200 ng of pertussis toxin (List Biological Laboratories Inc., Campbell, CA, USA) was injected intraperitoneally. …

Induction and assessment of EAE

EAE was induced as previously described [19]. Mice received a subcutaneous injection in the flank of 200 μg MOG35–55 peptide emulsified in CFA containing 500 μg Mycobacterium tuberculosis H37RA. Immediately thereafter and again 48 h later, the mice were given an intraperitoneal injection of 300 ng PTX in 100 μl phosphate-buffered saline (PBS). …

Immunization

Eight micrograms of OVA (Sigma) and 2 μg of cholera toxin subunit B (List Biological) in 6 μL of sterile PBS or 6 μL of PBS were administered intranasally. Mice were sacrificed 7 days later and parotid glands were removed and frozen. For detection of CD3+ cells, representative sections were prepared for fluorescent immunohistochemistry. The number of CD3+ cells was counted in 15 high power fields (hpf).
