… In addition, mice were weekly challenged with 10 ng SEB (List Biological Laboratories Inc., Campbell, CA) from day 49 through day 102 (8 weeks, short-term group) or day 186 (20 weeks, long-term group) after OVA instillation. …

Surgical Procedures

C5 Unilateral Spinal Cord Contusion

… Three days prior to being euthanized rats in Experiment 2 were anesthetized with XAK, and an axial incision to the ipsilesional (right) forelimb exposed the median and ulnar nerves,26 and the perineurium was removed. A 5-µL Hamilton syringe fitted with a custom 30 gauge needle (#7803-07, Hamilton Company, Reno, NV) was inserted into each nerve, and 2.0 µL of cholera toxin β subunit (CTB; 10 µg/µL; Product #104, List Biological Laboratories, Inc, Campbell, CA) was injected to label myelinated sensory afferents. Rats received 5 cc of LRS and cefazolin subcutaneously following surgery.

MC3R Expression in the VTA:

A cholera toxin B (CTB)-based retrograde tracing strategy was used to study whether Arc POMC neurons projected to the VTA. To label perikarya of neurons in the Arc nucleus projecting to the VTA, the rats (n=6) were treated with CTB (0.5% solution; #103, List Biological Laboratories, Campbell, CA) via unilateral iontophoresis (5A, 7s onoff) into the VTA for 20min.

EAE immunization and SU5416 treatment:

To induce EAE, 7-weeks old C57BL/6J female mice were injected subcutaneously in the flank and at the tail base with 200 µg of myelin oligodendrocyte glycoprotein 35 to 55 (MOG 3555) peptide emulsified in complete Freunds adjuvant (BD Biosciences, San Jose, CA) supplemented with 600 µg of mycobacterium tuberculosis (strain H37Ra; BD Biosciences). Two intraperitoneal injections of 400 ng pertussis toxin (List Biological Laboratories, …

Reagents:

Escherichia coli 0111:B4 LPS was purchased from List Biological Laboratories (Campbell, CA). …

ELISA and multiplex cytokine assays:

After stimulation with LPS at the indicated time points, cell supernatants were collected and analyzed using ELISA Kits (eBioscience) or Bioplex (Bio-Rad) according to the manufacturers protocols.
