Tracer injections:

Rats (6 to 7 weeks old, 260 to 300 g, Charles River) were anesthetized as described above and placed in a stereotaxic apparatus. Glass micropipettes (4 to 5 m in outer diameter) were backfilled with a 1% solution of CTb [List Biological Laboratories; diluted in 0.1 M phosphate buffer (PB) at pH 6.0] for injection in the dentate gyrus (n = 4), the retrosplenial cortex (n = 4), and the SUM (n = 4). …

…Thus, this study used anterograde tracer biotinylated dextran amine and the retrograde tracer cholera toxin B subunit to examine the organization of the thalamocortical projections of the AV.

… A glass micropipette (2030 m id) filled with 1% low salt CTB (List Biological Laboratories, Campbell, CA) in distilled water was stereotaxically lowered into part of the left retrosplenial cortex or presubiculum where dense terminal labeling had been present in the anterograde …

Neural tracing experiments

Five wild type (WT) mice and five cPcdh-a KO mice of aged 8–10 weeks were anesthetized intraperitoneally with a mixture ofketamine (300 mg/kg; Daiichi-Sankyo, Tokyo, Japan) and xylazine(30 mg/mL; Bayer, Leverkusen, Germany). The cholera toxin bsubunit (CTb, 5 ng in 1 µL of saline; List Biological Laboratories,Campbell, CA, USA), an anterograde neural tracer, was injectedinto the left eye using a glass pipette. …

Mouse anti-CFA and anti-toxin antibody titration:

Anti-CFA/I and anti-CS1, -CS2, -CS3, -CS4/CS6, -CS5/CS6, and anti-STa and anti-LT IgG antibodies in serum of each mouse were titrated as described previously [34,3739]. Briefly, 500 ng CFA/I, CS1, CS2, CS3, CS4/CS6, and CS5/CS6 heat-extracted from ETEC field isolates or recombinant E. coli strains [39] (Table 1), or 100 ng LT (List Biological Laboratories, Inc., Campbell, CA) were coated to each well of H2B plates …

Overview of experiments:

Two experiments were conducted to assess the role of the connection between the VP-m and MD and the VP-m and VTA during specific PIT. Experiment 1 aimed to investigate the neuronal activity during specific PIT of neurons in the VP-m projecting to the MD or the VTA using the neuronal activity marker c-Fos combined with retrograde tracers, Cholera toxin-b subunit (CTb, catalog #104; List Biological Laboratories)…

Histology – CTb and FG injection sites:

To locate the injection sites, sections containing the MD were stained using a goat anti-CTb antibody for visualization of the injection site…After, sections were incubated for 48 h in 4°C in a solution containing the anti-CTb antibody (1:2000, catalog #703; List Biological Laboratories),…

Peanut, Ara h 1, 2, 3 and 6 sensitization and challenge:

… Cholera toxin (CT) was obtained from List Biological Laboratories, Inc. (CA, USA). To elicit oral sensitization to peanut proteins, 8 mice were intragastrically (i.g.) dosed by gavage with 6 mg PE or 250 µg Ara h 1, 2, 3, or 6 plus 15 µg CT per mouse for three consecutive days, and this was repeated every week for four weeks (exposure on days 0, 1, 2, 7, 14, 21 and 28). Control groups received PBS plus 15 µg CT. …
