Cell Culture:
Bone marrowderived macrophages (BMDMs) were cultured in macrophage medium (RPMI 1640, 10% FBS, 30% L929 cell supernatant, 2 mM l-glutamine, 100 IU/mL penicillin, and 100 g/ml streptomycin) as described (20). After being cultured in macrophage medium for 6 days, BMDMs were isolated, counted, and cultured in macrophage media for 24 hours and then stimulated with LPS (10 or 100 ng/ml), IL-4/IL-13 (10 ng/ml), IL-10 (10 ng/ml), or RPMI 1640 for up to 48 hours. Alveolar macrophages isolated with repeated BAL using PBS were cultured for 24 hours in macrophage media and then stimulated with LPS for 4 hours. BEAS-2B cells were cultured in RPMI 1640 supplemented with 10% BSA, penicillin, and streptomycin for 5 to 6 days until they reached 90% confluence. The culture medium was then replaced, and low-molecular-weight heparin, syndecan-4, or RPMI 1640 was added for 1 hour. Cells were washed with PBS and incubated with LPS (1,000 ng/ml), TNF- (1 ng/ml), or RPMI 1640 without heparin or syndecan-4 for 3 hours. Mouse tracheal airliquid interface cultures were performed as described and stimulated with LPS or RPMI 1640 for 4 and 24 hours (33). Supernatants were removed and RNA was harvested.

Disease Induction and Assessment of EAE:
EAE was induced in female C57BL/6 mice (Jackson Laboratories, Bar Harbor, ME), aged 7 to 8 weeks, by injecting subcutaneously 50 µg of myelin oligodendrocyte glycoprotein (MOG)3555 in complete Freund’s adjuvant (Fisher Scientific, Waltham, MA) supplemented with 4 mg/mL Mycobacterium tuberculosis on day 0.32,33 Intraperitoneal pertussis toxin (300 ng/200 µL; List Biological Laboratories, Hornby, ON, Canada) was administered on days 0 and 2. Laquinimod (25 mg/kg body weight) was given every day by oral gavage in 100 µL of saline, whereas 100 µL of saline was used as the vehicle control. …

Induction of EAE:
EAE was induced in 6-wk-old male mice by s.c. injection with 100 mg myelin oligodendrocyte glycoprotein (MOG)3555 peptide (MEVGWYRSPFSRVVHLYRNGK; United Peptide, Rockville, MD) emulsied in 100 ml CFA (Sigma-Aldrich, St. Louis, MO) containing 2 mg/ml heatkilled Mycobacterium tuberculosis H37RA (Difco, Detroit, MI). Mice were also injected i.p. with 200 ng pertussis toxin (List Biological Laboratories, Campbell, CA) on day 0 and day 2. Clinical signs of EAE were recorded daily using a 04 scoring system: 0, normal; 1, limp tail; 2, unsteady gait; 3, hind-limb paralysis; 4, fore-limb paralysis.

Product: Cholera Toxin B Subunit (Choleragenoid) from Vibrio cholerae in Low Salt
Experiment 1: identification of refeeding-activated neurons in the PVN that project to the dorsal vagal complex
Rats were anesthetized ip with ketamine/xylazine (ketamine 50 mg/kg, xylazine 10 mg/kg body weight) and their heads positioned in a stereotaxic apparatus with bregma and lambda in the horizontal plane. Through a burr hole in the skull, a glass micropipette (20 µm outer tip diameter) containing 0.5% solution of the retrograde tracer, cholera toxin- subunit (CTB; List Biological Laboratories, Campbell, CA), was lowered into the brain at stereotaxic coordinates corresponding to the NTS based on the atlas of Paxinos and Watson (7): 5.0 mm posterior and 1.9 mm dorsal to the interaural line and 0.5 mm lateral to the midline. …
