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.

Cell cultures and stimulation

Peritoneal macrophages were isolated from mice after being injected intraperitoneally with 3% thioglycollate solution for 4 days. For NLRC4 inflammasome activation, peritoneal macrophages were treated with LFn-Fla or LFn-Fla 3A with PA for the indicated times. For NLRP1b inflammasome activation, the cells (J774, RAW264.7, or RAW-asc) were cultured with LF (2 μg/ml; no. 172C, List Biological Labs) together with PA (2 μg/ml; no.171E, List Biological Labs) for the indicated times. …
