CCR2⁺ cell depletion strategy:

For depletions of CCR2⁺ cells, CCR2-DTR mice and control littermates received 250 ng of diphtheria toxin i.p. one day prior to infection. Diphtheria toxin was purchased from List Biological Laboratories (Campbell, CA) and reconstituted at 1 mg/ml in PBS. Aliquots were stored at 80C. The specificity and efficiency of depletion in the lung was confirmed by flow cytometry.

… Prior to the start of surgery, animals were injected in the left hind quarter with ketoprofen (KetofenTM, Fort Dodge Animal Health, Fort Dodge, IA; 5 mg/kg S.C.). Animal were anesthetized with isoflurane (5% induction and 2% for maintenance, Henry Schein, Melville, NY). In order to label spinally projecting neurons in RVLM, each group of rats received an injection of cholera toxin B subunit (CTB, 1%, List Biological Laboratories, Inc., Campbell, CA), a retrograde tracer, into the T9-T10 region of the spinal cord as in previous studies (Quote Nicks and the NR1 paper). Briefly, rats were put in a stereotaxic head holder and the T9-T10 region of the thoracic spinal cord was exposed. CTB (3 X 30 nl) was microinjected bilaterally into the T9-T10 of the spinal cord. …

Immunology:

Anti-CT and -LT IgG and IgA antibodies were measured by enzyme-linked immunosorbent assay (ELISA) (18).  The critical reagents used in these assays were as follows: cholera toxin B subunit (catalog no. 103B, lot no. 10327A, 1.0 mg; List Biological Laboratories, Inc., Campbell, CA), which was resuspended in 0.2 ml deionized (DI) water for a final concentration of 5.0 mg/ml, and stored at 2 to 8C; …

Infection, Induction and Scoring of EAE:

Female 6- to 8-week-old BALB/c mice were used throughout this study. New-born mice 6 to 12 h postpartum were inoculated i. p. with 200 PFU of wild-type MCMV (MW97. 01 strain) or 200 µl of phosphate buffered saline (PBS) as a control. EAE was induced via subcutaneous administration of 200 L of a suspension at 2 sites above the hind flanks. … Each mouse was immediately injected intraperitoneally and 48 hours later with 300 ng of pertussis toxin (List Biological Laboratories, Campbell, USA) in 100 µL of 0.9% NaCl. …

Induction and Assessment of EAE:

… Mice also received 200 ng of pertussis toxin (List Biological Laboratories) i.p. in 0.2 ml of PBS on the same day and 2 days later. Clinical signs of EAE were assessed daily with a 06 scoring system (0, no signs; 1, tail limpness; 2, impaired righting re- flex; 3, hind limb weakness; 4, hind limb paralysis; 5, hind limb paralysis with fore limb weakness; 6, death). …

THP1 Assay:

THP1-XBlue cells were grown in RPMI 1640… LPS was diluted in medium to have a final concentration of 10 ng/ml, and 30 l/well were added for 24 h at 37C. …

U937 assay:

U937 cells were grown in RPMI 1640 (Sigma) with 10% heat-inactivated FBS and 2 mM glutamine (Sigma). U937 cells were differentiated into macrophages with 25 nM of phorbol myristate acetate (Sigma) during 72 h in order to increase their responsiveness to LPS and establish adherent cell conditions. …
