Experimental autoimmune encephalomyelitis immunization

C57BL/6 mice were immunized subcutaneously (s.c.) in the flank with 200 μg of MOG35–55 peptide emulsified in complete Freund´s adjuvant (CFA) containing 0.1 mg Mycobacterium tuberculosis (Becton Dickinson) along with an intraperitoneal injection of 200 ng pertussis toxin (List Biological Laboratories Inc.) on the day of immunization and two days later. …

Experimental design animal study
A schematic representation of the experimental timeline is depicted in Fig. 1B. Mice were orally exposed, by using a blunt needle, to 0.5 mL raw milk, the milk samples heated at 50 °C, 60 °C, 65 °C, 70 °C, 75 °C, 80 °C or PBS (as a control) for eight consecutive days (days-9 to -2). Subsequently, mice (n = 8 per group) were orally (by means of gavage) sensitized to 20 mg ovalbumin (OVA; 20 mg per 0.5 mL PBS; grade V; Sigma-Aldrich) using 15 μg cholera toxin (CT; List Biological Laboratories, Campbell, CA, USA) as an adjuvant (days 0, 7, 14, 21, and 28). …

Treg cell isolation and adoptive transfer

… Diphtheria toxin (List Biologicals, CA) was administered via intraperitoneal injection in 100µL of sterile PBS in the following doses and days relative to influenza A virus infection (day 0): 50 mcg/Kg on day -2 and 10 mcg/Kg every 48 hours starting on day 0 and ending on day 28 post-infection. Five days later, 1 x 106 young or aged splenic Treg cells in 100 µL of sterile PBS were transferred via retro-orbital injection into the
influenza-treated Foxp3DTR mice.

Enzyme-linked immunosorbent assay(ELISA)

… To measure the levels of IgG against CCP2, we used a commercially available ELISA
kit (Euro-Diagnostica, Malmö, Sweden). For the detection of anti-inuenza, and anti-diphtheria toxin
antibodies, 96-well plates were coated with 1 μg/ml of A/H1N1 subunit (Bio-Rad, Hercules, CA, USA) and
diphtheria toxin (List Biological Laboratories, Campbell, CA, USA), respectively. …

Experiment 3:

… Upon examining the sections through the PBel in animals with injections of AAV-FLEX-ArchT-GFP into the DR of Sert-Cre mice, we found intense innervation of the external lateral part of the parabrachial (PBel) area. To further confirm that PBel receives innervation from serotonergic neurons in the DR, we also injected Sert-L10 mice (n = 4) with retrograde tracer, cholera toxin subunit b (24 nl, 0.2% – CTb, List Biological Laboratories Inc.) unilaterally in the lateral PB. One week later these mice were sacrificed, brains perfused, and tissue sections processed for immunohistochemistry for CTb using the procedure described below.
