Materials:

…Lipopolysaccharide (LPS) was obtained from List Biological Laboratories (USA). …

Human umbilical vein endothelial cells (HUVECs) were purchased from Lonza (USA) at passage 1 and maintained in EBM2 Bullet kit growth medium at 37C in a humidified atmosphere of 5% CO2. In all experiments, cells were used at passage 4~9. HUVECs were plated at 90~95% confluence treated for 1 h with 1, 10, and 20 M of quercetin prior to LPS (1 g/mL) stimulation for 1 or 8 h. …

IFN- neutralization assay:

The ability of IFN- to upregulate LPS-induced production of TNF- by PBMCs was used to test for the neutralizing activity of sera containing high-titer blocking antibodies to IFN-.

AntiIFN-positive sera, negative control sera, or FBS were preincubated for 30 minutes in a 96-well plate (Corning, Corning, NY) at a dilution of 1:5 in RPMI 1640…or LPS (1 g/mL; LIST Biologicals, Campbell, Calif) alone or both stimuli were added.

Detection of serum IgG antibodies to pertussis antigens:

Nunc MaxiSorp 96-well plates were coated overnight with 0.2 g/ml pertussis toxin (PT), 2 g/ml pertactin (PRN), or 0.2 g/ml fimbriae 2/3 (FIM) in 100 mM carbonate buffer, pH 9.6. Additional plates were coated with 0.5 g/ml filamentous hemagglutinin (FHA) in PBS, pH 7.4. All antigens were purchased from List Biologicals (Campbell, CA). For analyzing antibody responses to whole B. pertussis cells, plates were coated with heat-killed strain D420 prepared as described above. For coating, plates were incubated at 28C for PRN, FIM, and FHA or at 37C for PT and B. pertussis cells. …

Induction of EAE:

… Mice were anesthetized with 3% isoflurane (Vedco, Inc., St. Joseph, MO) and injected subcutaneously (s.c.) at multiple regions of the back with 100µl (total volume of 300µl) of PLP139151. Intraperitoneal (i.p.) injections of 200ng pertussis toxin (List Biological Laboratories, INC., Campbell, CA) were administered on days 0 and 2 post immunization.

We temporarily depleted CD207⁺ DCs by injecting diphtheria toxin (DT) into MuLanDTR mice that express transgenic receptors for DT (DTR) in all CD207⁺ DCs³⁵. Compared to untreated MuLanDTR mice, MuLanDTR mice treated with DT for 8 days had reduced percentages of CCR10⁺MHCII⁺ ILCs in sLNs but not in the skin

Diphtheria toxin treatment:

Mice were injected intraperitoneally with 1g diphtheria toxin (List Biological Labs, Inc, Campbell, CA) per week and analyzed 821 days after injection.

…In addition to 6% OVA, all groups of mice were challenged 3 times a week with 10 ng of Staphylococcus aureus enterotoxin B (SEB; List Biological laboratories, Campbell, Calif) from the 8th through the 14th week after OVA instillation.

Preparation of Antigen and Induction of EAAU:

… In order to induce EAAU, the Lewis rats simultaneously received two injections of different MAA preparations. … (2)MAA was emulsified with 1 µg purified Bordetella pertussis toxin (List Labs,Campbell,CA,USA) and injected intraperitoneally in a total volume of 0.05mL. In the control group, 0.05mL of PBS was simultaneously injected into the left hind foot pad and intraperitoneally in the rats.
