Immunofluorescence:

… A 25µl Hamilton syringe was used to bilaterally inject 10 µl of 5mg/ml Cholera Toxin B subunit solution (CTB, List Biological Laboratories) in the intrapleural space (Mantilla et al, 2009). Rats were allowed to recover for 5 days prior to electrophysiological experiments described above (neural apnea n=3; time control n=4). Following electrophysiological measurements, animals were transcardially perfused with 4% paraformaldehyde (PFA) in 1 phosphate-buffered saline (PBS, pH 7.4). …

Liver Fibrosis Models:

Adult male mice at least 6 wk of age were used. Hepatic fibrosis was induced by two times per week i.p. CCl₄ (0.4 L/g; Sigma) diluted 1:3 in olive oil (Sigma) for 4 wk (nine injections). Animals were culled at stated time points after the final CCl₄ injection. For depletion studies, DT (10 ng/g in PBS; List Biological Laboratories) or PBS control was administered to fibrotic CD11B-DTR or WT mice i.v. through the tail vein at the stated time points. …

Induction of peanut allergy, EPIT treatment and induction of esophageal and jejunal injuries:

Twenty-four mice were first sensitized to peanut proteins by means of 6 intra-gastric gavages (D1, D7, D13, D19, D25, D32) as previously described [4], with 1 mg of PPE mixed with 10 µg of CT. …

Immunization and challenge:

Ovalbumin (Sigma-Aldrich, St. Louis, MO) and cholera toxin (CT) mucosal adjuvant (List Biological Laboratories, Compel, CA) were purchased and stored according to the manufacturer’s protocols. Mice were intranasally immunized twice, one week apart, with 10 µL of PBS containing 10 µg Ovalbumin plus 1 µg CT (OVA+CT) or 1 µg CT alone (CT). …

Expression and Labeling of M18 scFv :

A standard 3-ml culture of cells harboring plasmids to surface display M18 scFv (e.g. pBAD_M18_138) was grown in LB medium (BD Diagnostics) in the presence of 30 g/ml chloramphenicol (Thermo Fisher Scientific) to an optical density (A₆₀₀) of 0.6 at 25 C. Cells were then induced via the addition of 0.2% l-arabinose (Sigma) to express M18 scFv for 12 h at 25 C. The presence of M18 scFv on the surface of E. coli was characterized by the ability of intact cells to bind antigens (PA₆₃ and PAD4) using flow cytometry. PAD4 containing FLAG epitope tag (rPAD4) was recombinantly expressed in E. coli and purified as described previously (35), and PA₆₃-FITC was obtained from List Biological Laboratories, Inc. …

EAE induction:

EAE was induced in 6- to 8-week-old female mice by subcutaneous immunization with 100 g of MOG_35-55 peptide (MEVGWYRSPFSRVVHLYRNGK; NeoMPS, San Diego, CA) emulsified in CFA containing 200 g of heat-killed Mycobacterium tuberculosis H37RA (Difco, Detroit, MI) on day 0. Additionally, mice received 200 ng of pertussis toxin (List Biological Laboratories, Campbell, CA) i.p. in 0.5 ml of PBS on days 0 and 2. …

Induction and evaluation of EAE:

Mice were immunized for the induction of EAE using a 2 or 1 immunization protocol … One week later, all mice received an identical injection of MOG₃₅₅₅-CFA. For the 1 immunization protocol, mice received a sonicated emulsion of 200 g MOG₃₅₅₅ and CFA containing 200 g Mycobacterium tuberculosis H37RA by subcutaneous injections, immediately thereafter, each animal received 200 ng PTX (List Biological Laboratories) by intravenous injection. Mice were scored daily for clinical quantitative trait variables beginning at day 5 after injection as follows: …
