Immunisation, H. pylori challenge and bacterial quantification in the stomach:

Groups of mice (n=5) were immunised orally four times in two rounds on days 0 and 1; 14 and 15. One hour prior to immunisation, food was withdrawn. Mice were orally gavaged with 200l of 0.3M sodium bicarbonate buffer. After 20min, mice were gavaged with 200l of sterile Phosphate-buffered saline (PBS) containing 110⁹ formalin-killed H. pylori Hel 305 with or without -GalCer (10g) (Avanti Lipids) or CT (10g) (LIST Biologicals), or with PBS alone. …

Perfusion and tissue processing

… For CT-B processing, sections were first blocked for endogenous peroxidases (Bloxall), washed (0.1M TBS-TX), and then treated with 10% horse serum (2h, at room temperature). Sections were then incubated in anti-CT-B made in goat (List Biological #703; 1:4000 dilution in TBS-TX) and 3% horse serum for 2-3 days at 4°C. …

Active and passive EAE induction:

For active EAE induction mice were immunized s.c. at the lateral pectoral regions with 2 × 100 µg murine MOG₃₅₅₅ peptide (MEVGWYRSPFSRVVHLYRNGK; GenScript) emulsified in CFA (BD DifcoTM) containing 4mg/ml Mycobacterium tuberculosis H37 Ra (BD DifcoTM). Two i.p. injections of 200ng pertussis toxin (List Biological Laboratories) in PBS were given 0 and 2 days post-immunization. …

Degranulation Assay:

The degranulation was measured by -hexosaminidase release as described previously [51]. Briefly, transfected RBL-2H3 cells (5 10⁴ cells per well) were seeded into a 96-well, white, clear-bottom cell culture plate and incubated overnight in a 37 C incubator with 5% CO₂. To determine the inhibitory effects of PTx and YM-254890 on MC degranulation, cells were pretreated with PTx (100 ng/mL, 16 h) and/or YM-254890 (10 M, 5 min) prior to stimulation with SP. Cells were then washed twice and suspended in a total volume of 50 L HEPES buffer containing 0.1% bovine serum albumin (BSA). …

PTX and TCDD Administration:

… Groups of 3–5 mice were first injected IP with vehicle (CO), or TCDD (25 μg/kg body weight) then injected IP with 400 ng/mouse PTX (List Biological Laboratories, Campbell, CA, United States). Twenty-four hour later, the mice were rechallenged with the same dose of PTX intraperitoneally, as described (Elliott et al., 2018).
