(B) Circulating frequencies of memory space P14 CD8+ T cells prior to antibody administration. (C) Mice from (B) were given control IgG or Thy1.1-depleting antibodies as explained in expressing OVA (LM-OVA), rather than LCMV, as expressing ovalbumin (LM-OVA) was delivered intravenously (1 x 107 CFU) in 200 l of PBS. Vaccinia disease (VacV) expressing GP33-41 (VacV-GP33) and ovalbumin257-264 (VacV-OVA) have been previously explained and were propagated using BSC-40 cells and standard protocols [53, 54]. Infections with VacV were performed on anesthetized mice by placing 1C5 x 106 PFU of disease in 10 l of PBS within the ventral part of the ear pinna and then poking the disease coated pores and skin 25 times having a 27G needle. For depletion of Thy1.1 expressing CD8+ T cells from your circulation, mice were treated with 1 g of control rat IgG (Sigma) or anti-Thy1.1 antibody (clone 19E12, BioXCell) 1C3 instances in 200 l of PBS by i.p. injection. Quantification of VacV from infected pores and skin Quantification of viral weight in the infected skin was identified using standard plaque assays on BSC-40 cells. Briefly, infected ears were eliminated and homogenized in 1 ml of RPMI supplemented with 1% fetal bovine serum. Pores and skin homogenates were then subjected to three rounds of freeze-thaw before serial dilutions were inoculated on BSC-40 cells inside a 12-well plate that were then covered with 1% Seakem agarose in Modified Eagle Medium (Gibco). Plaques were visualized three days later on following over night incubation with Neutral Red dye. Leukocyte isolation from skin Ears from infected mice were removed and the dorsal and ventral sides of the ear pinna were separated and allowed to incubate for 1C2 hours at 37C with 1C2 ml HBSS (Gibco) made up of CaCl2 and MgCl2 supplemented with 125 U/ml collagenase (Invitrogen) EBE-A22 and 60 U/ml DNase-I (Sigma-Aldrich) at 37C. Whole tissue suspensions were then generated by softly forcing the tissue through a wire mesh screen. Leukocytes were then purified from whole tissue suspensions by re-suspending the cells in 10.
