Induction of EAE (experimental autoimmune encephalomyelitis):

To induce EAE, B10.PL mice were injected subcutaneously with a CFA emulsion containing 100 g Ac19 and 200 g of Mycobacterium tuberculosis H37Ra (Difco) divided among 3 sites on their backs. 1 and 3 day after the immunization, the mice were injected intraperitoneally with 100 ng of pertussis toxin (List Biological Laboratory) in PBS. …

Diphtheria toxin treatment:

Diphtheria toxin (DT) was administered to DTR mice, genetically engineered to express the human DTR selectively in hair cells (Tong et al. 2015). A single 25 g/kg dose of DT (List Biological Laboratories, no. 150) was delivered via intramuscular injection to 4-wk-old DTR mice. Within 6 days after DT injection, DTR mice lose all of their hair cells and are completely deaf (Tong et al. 2015). After DT injection, DTR mice were allowed to survive for 2 wk before tissue collection.

Tracer experiments

Cholera toxin subunit injections:

…Briefly, the retrograde tracer cholera toxin subunit (CTB; List Biological Laboratories, Campbell, CA) was targeted to the PVN (n = 10) and to the PIL (n = 15) in lactating mother rats at postpartum day 4. …Glass micropipettes of 15 to 20 µm internal diameter were filled with 0.25% CTB dissolved in PB and lowered to the following stereotaxic coordinates (35): anteroposterior (AP), 1.7 mm; lateral (L), 0.4 mm; ventral (V), 7.4 mm for the PVN; and AP, 5.2 mm; L, 2.6 mm; and V, 6.4 mm for the PIL. CTB was applied by iontophoresis using a constant current source…

Visualization of CTB:

Sections were pretreated in PB-containing 0.5% Triton X-100 and 3% bovine serum albumin for 1 hour. Sections were then incubated in goat anti-CTB antiserum (1:10,000; #703, List Biological Laboratories; …

Double immunolabeling of CTB and TIP39 or CB:

Every fourth free-floating section was first stained for TIP39 by using FITC-tyramide amplification fluorescent immunocytochemistry, as described earlier. Sections were then incubated overnight in goat anti-CTB or …
