EAE:

…Following immunization, 200 ng of pertussis toxin (List Labs) was injected ip into mice on Day 0, followed by a 400 ng pertussis toxin ip injection on Day 2. IL-2 was administered either before immunization of mice with MOG (called pre-treatment) or after immunization…

Induction of EAE and clinical evaluation:

SJL/J female mice (57 weeks old) were immunized subcutaneously (s.c.) with 200g of PLP₁₃₉₁₅₁ in a 02-ml emulsion composed of equal volumes of phosphate-buffered saline (PBS) and complete Freund’s adjuvant (CFA) containing killed Mycobacterium tuberculosis strain H37RA (at a final concentration of 4mg/ml; Difco, Detroit, MI, USA). The PLP₁₃₉₁₅₁ in CFA was administered to regions above the shoulder and the flanks (total of four sites; 50 l at each injection site). Then, 200ng of pertussis toxin (List Biological Laboratories Inc., Campbell, CA, USA) was injected intraperitoneally (i.p.) on the day of immunization (day 0) and 2 days post-immunization. …

EAE Induction:

Unless otherwise stated, mice received 300 g of rodent MOG₃₅₅₅ peptide emulsified in complete Freunds adjuvant containing heat-killed Mycobacterium butyricum (Difco, Detroit, MI) via s.c. flank injection on days 0 and 7; on days 0 and 2, mice received 500 ng of pertussis toxin (List Biological Laboratories, Campbell, CA) via i.p. injection. …

BST Lesions:

To enhance visualization of vlBST injection sites and to reveal the central distribution of neurons projecting to those sites, a subset of rats used in Experiment 1 (described below) received vlBST microinjections of DSAP (n=2) or vehicle (n=2) mixed in a cocktail with a retrograde neural tracer, cholera toxin subunit (CTB, 0.15%, List Biological Laboratories, Inc. Campbell, California). CTB in the injectate did not interfere with DSAP lesion efficacy…

Behavioral testing on the EPMZ:

… In Experiment 1, maze-nave rats was tested only once in the EPMZ, two weeks after surgery (n=22 DSAP, n=15 sham), to assess maze behavior after either i.p. saline or YO. Two rats within each surgical lesion group were those that received co-microinjection of CTB together with DSAP or saline vehicle into the vlBST, as described above (BST lesions). …

Perfusion And Immunohistochemistry:

A second set of tissue sections from rats that received vlBST microinjections of CTB+DSAP or CTB+vehicle was processed for dual immunofluorescence to localize CTB (using goat anti-CTB, 1:5000, List Biological Laboratories) and mouse anti-DbH (1:5000), in order to simultaneously visualize vlBST injection sites, non-lesioned retrogradely labeled neurons projecting to those sites, and DbH-positive neurons and fibers. CTB immunofluorescence was visualized using CY3-conjugated AffiniPure donkey…

…To induce EAE, mice were immunized subcutaneously with 200 g MOG emulsified in complete Freunds adjuvant (Difco, Lawrence, KS) supplemented with 5 mg/ml Mycobacterium tuberculosis H37Ra (Difco, Lawrence, KS). The mice were injected twice i.p. with 200 ng of pertussis toxin (List Biological Laboratories, Campbell, CA) at the time of immunization and 48 hours later. The mice were then monitored daily for clinical symptoms of disease, …

Conditioning and dorsal column lesions:

…Another set of C57BL/6 129/SvJ (n = 5) and Slpi^/ (n = 7) mice received only dorsal column lesions. At 5 weeks after surgery, 2 µl of 1% cholera toxin B subunit (CTB; List Biological) was injected into the right sciatic nerve of each animal, and the animals were transcardially perfused with 4% paraformaldehyde (PFA) 3 d later.
