In vivo intoxication experiments:
Lyophilized recombinant PA, LF, and mutant LF (E687C) were purchased from List Biological Laboratories, Inc. (Campbell, CA) and reconstituted in sterile water (stock concentration: 1 mg/mL in 5 mM HEPES, 50 mM NaCl, pH 7.5). Anthrax LT was administered with a fixed ratio of PA/LF of 2.51 by weight (molar ratio: 2.71). Unless otherwise indicated, mice were injected intravenously with 200 g PA/80 g LF (C57BL/6J) or 100 g PA/40 g LF (BALB/c), administered in a total volume of 0.3 mL of PBS. As a negative control, selected mice received the same volume of PBS alone. …
Some experiments involved the concomitant administration of broad-spectrum antibiotics with anthrax LT. Both antibiotics were administered subcutaneously beginning the day of LT treatment (amoxicillin: 100 mg/kg every 8 hours, and gentamicin 16 mg/kg one time per day, Sigma, St. Louis, MO). Antibiotic therapy was maintained until the animal succumbed to toxemia or until the termination of the experiment.

Nasal vaccination:
Mice were anesthetized with isourane before vaccination. Vaccines were administered intranasally in 10 ml (5ml per nostril). Nonchimeric mice were vaccinated on days 0, 7, and 21. Chimeric mice were vaccinated on days 0, 7, 21, and 42. For each chimeric study replicate, mice were divided into groups of 4 to 8. Vaccine groups included PBS alone, recombinant LF (rLF) alone (#172; List Biological Laboratories Cambell, CA; 4 endotoxin units [EU]/mg), rLF + 4 mg IL-1a (400-ML; 0.00144 EU/mg; R&D, Minneapolis, MN), and rLF + 1 mg cholera toxin (CT) (EU/mg unknown; List #100B). For three of the four Il1r1 chimeric mouse experiments, mice were vaccinated with 25 mg LF for the day 0, 7, and 21 immunizations and 50 mg LF on day 42. For the remaining experiment, mice were immunized with 50 mg LF each time. The calculated endotoxin delivery per mouse was 0.20 (LF alone) to 0.22 EU (LF + IL-1a). Data from each group for all repeat experiments were combined and analyzed together. Mice vaccinated with LF + CT served as a positive control, and LF + CT-vaccinated mice responded similarly in all four chimeric groups.

Experimental protocols:
After completion of the surgical procedures, anesthetized rats were allowed to stabilize for 60 min before initiation of experimental protocols. As described by Cui et al. (4, 6), rats received LeTx [LF (100 g/kg) + PA (200 g/kg) infused at 0.5 ml/h] or vehicle (PA + PBS with 1% BSA or PBS with 1% BSA infused at 0.5 ml/h). LF and PA are recombinant proteins prepared from B. anthracis and purchased from List Biological Laboratories. Experiments were completed in intact and SAD rats. LeTx or vehicle was infused intravenously via a femoral venous catheter, and the dose of LeTx was chosen on the basis of the time course of physiological responses to intravenous LeTx infusions as reported by Cui and colleagues (6). MAP, HR, and SND were recorded continuously during intravenous LeTx or vehicle infusions. The maximum infusion duration was 6 h; however, because of LeTx-induced reductions in arterial blood pressure, the majority of experiments were terminated before 6 h. Additional experiments involved the intravenous infusion of sodium nitroprusside (SNP) at a dose (20 g/kg) that reduced basal levels of MAP to 5060 mmHg. At the end of experiments, rats were euthanized by an overdose of methohexital sodium (150 mg/kg iv).
