EAE induction and exosomes treatment

… To induce EAE, female C57BL/6J mice were immunized with 200 μg MOG35–55 (Sinobioway Co., Ltd., Zhangzhou, China) in complete Freund’s adjuvant (Chondrex Inc., WA, USA) with 4 mg/mL heated-killed M. Tuberculosis (H37Ra, non-viable). Pertussis toxin (List Biological Laboratories Inc., CA, USA) was intraperitoneally injected at 400 ng on days 0 and 2. After 15-20 days, mice displayed the peak of the disease showing complete paralysis of the tail and hind limbs. …

4.5. Treatment of Stx2 on the Chip

Stx2 (List labs; Campbell, CA, USA) was diluted in the DMEM/F12 as supplemented with 5% (v/v) FBS, 100 unit/mL penicillin, and 100 μg/mL streptomycin. One hundred microliters of Stx2 was added only in the gut module, i.e., after assembly of the gut and kidney modules.

Intramuscular injections

All surgeries were conducted under aseptic conditions on P2 neonates anesthetized by deep hypothermia. For induction, pups were placed in latex sleeves gently buried in crushed ice for 3–5 min and maintenance (up to 15 min) was achieved by placing anesthetized pups on a cold pack (3–4 °C). Following small incisions of the skin to expose the targeted muscles, the viral cocktail (or 0.5% Cholera toxin subunit B (CTB) (List Labs) for labeling of the infrahyoids) was injected via a pneumatic dispense system (Picospritzer) connected to a glass pipette (tip diameter ca. 0.1 mm) mounted on a 3D micromanipulator to guide insertion in the desired muscle. …

Stromal Cell Culture

Mouse lung fibroblasts were isolated from whole lung explants by digestion … For experiments, fibroblasts were used between passages 4 and 6. Fibroblasts were serum-starved with DMEM/F-12 medium containing 1% FBS for 24 hr before stimulation with IFN-β and lipopolysaccharide (LPS). Confluent cells were stimulated with LPS from Escherichia coli serotype 0111: B4 (lot no. 2014641; List Biological Laboratories, Campbell, CA) at 100 ng/ml and IFN-β (PBL Interferon Source; Piscataway, NJ) at 100 units/ml. After 4 hr of stimulation, the medium was removed, cells were washed with PBS, and RNA was extracted using RNAeasy Plus Mini Kit (Qiagen).

2.4.1. Retrograde labeling

… A pulled glass pipette (~20 μm outer tip diameter) was attached to the arm of the stereotaxic apparatus. A solution of 0.25% CTB (List Biological Labs, Campbell, CA, USA) in sodium phosphate buffer (pH 7.5) was backfilled through the pipette tip using negative pressure, then a wire connected to a current source (Stoelting) was inserted into the tracer solution. …

Induction and assessment of EAE

To induce EAE, 8-week-old female C57BL/6 or OptnΔCD11c and DKO mice with their littermates were immunized subcutaneously with 400 μg MOG35–55 peptide (Sangon) emulsified in CFA (Sigma) containing 4 mg/mL heat-killed Mycobacterium tuberculosis H37Ra (BD Biosciences) at day 0. In addition, 200 ng pertussis toxin (List Biological Laboratories) in 0.1 mL PBS was administered intravenously at day 0 and day 1 post immunization per mice.
