In vivo injections

After recovery, each pigeon received unilateral injections of one tracer, BDA (10,000 molecular weight; Molecular Probes, Eugene, OR, USA) or CTB (low salt; List Biological Laboratories, Campbell, CA, USA) on the right hemisphere (Fig. 1a, 1g). BDA (10% in phosphate-buffered saline [PBS], pH 7.4) was used for anterograde labeling, whereas CTB (1% in PBS) was used for retrograde labeling. …

Cell surface binding assay

Binding of WT and mutated TcdB to cells was analyzed by the cell surface binding assay21. Briefly, cells were exposed to TcdB (10 nM) or TcdB mutants (10 nM) for 10 min at room temperature. Cells were washed three times with PBS and lysed with RIPA buffer (50 mM Tris, 1% NP40, 150 mM NaCl, 0.5% sodium deoxycholate, 0.1% SDS, with a protease inhibitor cocktail (Sigma-Aldrich). Cell lysates were centrifuged and supernatants were subjected to western blotting using chicken polyclonal anti-TcdB IgY (List Labs, #754A, 1:2000) and goat anti-chicken IgY H&L (HRP) (Abcam, ab97135, 1:2000) antibodies to examine the binding of TcdB mutants. Chicken polyclonal anti-actin antibody (Aves Labs, ACT-1010, 1:2000) was used for negative control.

2.4.2 Oral tolerance induction, sensitization and challenge

… Two days after the last oral administration with the indicated pre-treatment, mice received five consecutive weekly oral sensitizations with 20 mg whey plus 10 µg cholera toxin (CT; List Biological Laboratories, Inc.) as adjuvant in 0.5 ml PBS for Group 2–7 to break oral tolerance for whey, and 10 µg cholera toxin in 0.5 ml PBS for the non-sensitized mice in Group 1. …

In vitro stimulation:

At the day of experiments the cell medium was replaced by pre-warmed 500 µL DMEM/antibiotics per well. Cells were stimulated with LPS (10ng/ml), TNF-α (1, 20, 100 ng/ml), IL-1β (1, 20, 100 ng/ml), galectin-3 (5, 50 or 100 ug/mL), or the combinations of LPS (10 ng/ml) or TNF-α (100 ng/mL) with galectin3 (5 ug/ml or 100 ug/ml) for 24 h. Cell culture media from each well was collected and stored at -80°C until analysis. Each experiment was repeated at three independent times using 6 animals/repeat. Vehicle and treatment wells were situated on the same plate and two samples for each treatment were analyzed for every repeat. …

EAE induction

Active EAE was induced as described [17, 21]. Subcutaneous flank injection of 300µg MOG35 − 55 peptide (MEVGWYRSPFSRVVHLYRNGK, Millipore Sigma) in complete Freund’s adjuvant (CFA, Difco) containing 300µg Mycobacterium tuberculosis was performed on day 0 (D0), and supplemented by intraperitoneal injections of 500ng pertussis toxin (PTX, List Biological) on D0 and D2 to heighten the auto-immune reaction to MOG peptide [22, 23]. …
