EAE induction:

EAE was induced by s.c. immunization of mice into the flanks with an emulsion of MOG3555 peptide (100 mg) emulsified in CFA supplemented with 4 mg/ml Mycobacterium tuberculosis extract H37Ra (Difco). Additionally, the animals received 200 ng pertussis toxin (List Biological Laboratories) i.p. on days 0 and 2.

Retrograde tracing:

To identify presympathetic RVLM-projecting PVN neurons (PVNRVLM), rats were anesthetized (ketamine-xylazine mixture, 90 and 50 mg kg-1, respectively, i.p.) and a stereotaxic apparatus was used to pressure inject 500 nl of rhodamine-labeled microspheres (Lumaflor, Naples, FL, USA) or cholera toxin B (CTB) (1%, List Biological Laboratories) into the RVLM (starting from Bregma: 12 mm caudal along the lamina, 2 mm medial lateral, and 8 mm ventral). …

Oral immunization:

Thirty minutes later, the mice were orally immunized with 1mg OVA (Sigma-Aldrich) and 10µg CT (List Biological Laboratories, Campbell, CA). This procedure was conducted on days 0, 7 and 14…One week after the final immunization, faecal samples and mononuclear cells from the iLP were collected for enumeration of OVA-specific antibody responses by enzyme-linked immunosorbent assay and ELISPOT, respectively¹³. In vivo CT challenge was performed by oral challenge of naive or immunized mice with 100µg of CT as previously described⁴⁶.
