Histochemistry and immunohistochemistry:

Rats were transcardially perfused with room-temperature 0.1 M sodium phosphate buffer, pH 7.3, followed by ice-cold 4% paraformaldehyde in phosphate buffer. Brains were postfixed… Conventional or immunofluorescence protocols were used to reveal the localization of anterograde/retrograde tracers or proteins of interest, following previously described methods (Deutch et al., 1996). For animals receiving nonconjugated CTb injections, a goat anti-CTb antibody (List Biological, Campbell, CA; RRID:AB_10013220) was used.

Anatomical tracers studies

Surgeries.

… For tracer injections, glass capillaries of 10 –25 m external tip diameter were backfilled with either a 1% solution of cholera toxin subunit B
(CTb; #104, List Biological Laboratories), dissolved in 0.05 M sodium phosphate buffer, a 2% solution of FluoroGold (FG; Fluorochrome),
dissolved in 0.9% saline, or a 5% solution of biotinylated dextran amine (BDA), 10,000 MW (#D1956, Invitrogen), dissolved in 0.1 M sodium
phosphate buffer. Discrete CTb and FG tracer deposits were made by iontophoresis (7 s on/off for 3–12 min; 1–5 A) in the PaMP region (0.7
mm posterior from bregma, 0.1 mm lateral from the center of the longitudinal sinus, and 7.2 mm ventral from the dura) or the RPa region (2.0
mm posterior from the interaural line, centered at the interaural line, and 8.8 mm ventral from the dura) as described in Table 1. In additional
animals, a deposit of the anterograde tracer BDA was made in the rPH (2.1 mm posterior from bregma, 0.2 mm lateral from the center of the
longitudinal sinus, and 7.4 mm ventral from the dura) to verify the results obtained with the retrograde tracers CTb and FG. Animals were
allowed to recover for 2–3 weeks before euthanasia. …

Dosage of anti-IL-6 and anti-Tetanus toxoid antibodies by ELISA:

Blood samples were taken from the monkeys in pre-dose (day -8), before the first immunization and then every two weeks until the end of the study (total of 9 samples). The IgG response against human IL-6 and Tetanus toxoid (TTx) was measured by ELISA as previously described¹⁷. Briefly, 50ng of human IL-6 (R&D Systems, Lille, France) or 50ng of TTx (List Biological Laboratories, Campbell, USA) were adsorbed on microtitration plates…
