2.2 DT or saline administration

Adult mice (6–16 weeks of age) received two intramuscular (IM) injections of DT (List Biological Laboratories, Campbell, CA) at either 25 ng/g (low-dose) or 50 ng/g (high-dose), spaced 2 days apart. Some control mice were administered IM saline.

… The mice were also injected intravenously with pertussis toxin (1040ng; List Biological Laboratories) on the day of immunization and after 48h. A control (CTR) group of 19 mice received complete Freund’s adjuvant and pertussis toxin, but no MOG35-55 peptide. Four mice were used in preliminary MRI experiments to set up the acquisition protocol …

Immunogenicity Studies of PA83 variants in Mice

Immunogenicity studies were performed with 3 and 10 μg of plant-produced dPA83(E), dPA83(P) and commercial recombinant PA (rPA, List Biological Laboratories, Campbell, CA, used as a positive control) proteins, administered intraperitoneally in seven- to eight-week-old Balb/c mice (6 animals/group). Mice were injected with three doses of protein samples adsorbed in 0.3% Alhydrogel at three-week intervals (day 0, 21 and 42). …

Systemic LPS challenge

After participants had undergone the IMQ skin challenge, an i.v. LPS challenge was performed on Day 7 after the start of treatment. All participants received 1 ng/kg purified Escherichia coli O113 LPS (List Labs, US, Lot #94332B4) reconstituted in 0.5 mL glucose 2.5%–sodium chloride (NaCl) 0.45% and administered as a 2- min infusion. To ensure that participants stayed adequately hydrated, glucose 2.5%–NaCl 0.45% was infused, starting 2 h prior to LPS administration and continuing until 6 h afterwards.18 Circulating inflammatory proteins (acute phase proteins, cytokines), leukocyte differentiation, and clinical parameters (pulse rate, blood pressure, and temperature) were evaluated over time, starting 0.5 h after the end of the infusion and ending up to 24 h after infusion.

Treatments

See Table S1 for list of Figures/panels in each figure and corresponding dose and exposure time. General information for the methods is provided here. To induce cytokine release from macrophages, microglia and BMDM cells were primed for 4–5 h (or time indicated in Table S1)with 1 μg/mL of LPS in culture medium, and some cells were pre-treated with 1 μM of CP456773/MCC950 for 30 min before ATP stimulation. Cells were then pulsed with 5 mM ATP for 30 min. For cytokine induction by anthrax lethal toxin (LeTx), LPS-primed cells were treated with LeTx at a final concentration of 250 ng/mL (LF and PA) for 3 h. Cell supernatants were collected and frozen at −80°C until assayed.
