Draining lymph nodes and spleen were used to gather activated T cells. Ovalbumin (Sigma-Aldrich, St. Louis, MO) or HSVgB (produced in the lab using baculovirus expression) were decontaminated of lipopolysaccharide (LPS) using a Triton X-114 LPS detoxification method 70 (link) were used in combination with polyI:C (GE Healthcare), pam3cys [N-palmitoyl-S-2,3-bis(palmitoyloxy)-(2R,S)-propyl]-(R)-cysteine-(S)serine-(S)lysine 4] (InvivoGen, San Diego, CA), anti-CD40 (clone FGK4.5, BioXCell, West Lebanon, NH) or the TLR7a agonist, 3M012, conjugated to Ovalbumin 32 (link),33 (link). For pathogen challenge, female B6 mice were injected with either 1×107 pfu/mouse of Vaccinia Virus Western Reserve Strain expressing the Ovalbumin protein (VV-ova) or 1×105 Listeria Monocytogenes (Lm) expressing whole Ovalbumin protein (Lm-ova).
