Topical Skin Immunization:

…After evaporation of the acetone, 25 l of an aqueous mixture containing 1 mg/ml cholera toxin (CT) adjuvant (List Biological Labs, Campbell, CA) was applied to each ear and uniformly spread with a small paint brush. Control mice received only the CT adjuvant, while experimental mice also received 50 l of an aqueous mixture containing 100 mg/ml ovalbumin (OVA) Ag (Sigma-Aldrich product #A5503) on each ear.

Treatment of Lang-DTR mice with Diphtheria Toxin:

For some cocultures (as indicated), WT or Lang-DTR mice were treated with diphtheria toxin (DT) (List Biological Labs, Campbell, CA). Mice were injected intraperitoneally with 1 µg DT in 100 µl PBS. Mice were treated one day preceding immunization and one day after…

Anterograde tracing of corneal afferent fibers:

Cholera toxin B subunit (CTb; 1% solution in 0.1 M phosphate buffer; List Biological Laboratories, Inc., Campbell, CA) was used as an anterograde tracer to identify central projections of corneal afferent fibers to the trigeminal dorsal horn (Hegarty et al. 2010;Todd et al. 2003;Aicher et al. 2013). Following FG injections, several drops of ophthalmic proparacaine hydrochloride, 5% solution (Bausch and Lomb, Tampa, FL) were placed in the left eye to reduce spontaneous eye movements and a 1% CTb solution (8 12 l) was placed on the corneal surface inside a steel ring for 30 min as previously described (Hegarty et al. 2010). Rats received a subcutaneous injection of ketoprofen (2.5 mg/kg) to reduce discomfort and were monitored during recovery from anesthesia.
