Figure 5From: Dendritic cell vaccines containing lymphocytes produce improved immunogenicity in patients with cancer Proliferation and cytokine production in DC vaccine prepared by adherence method is antigen specific. (A) Adherence DCs were co-cultured with apoptotic 3T3 (DC/ctrl) or with 3T3 infected with influenza (DC/flu) and assessed for proliferation by 3H thymidine incorporation at 24, 48 and 96 hours beyond day 8 (the day DCs would have been administered as a vaccine). Results are of triplicate wells. * indicates p < 0.05. (B) Adherence DC/ctrl and DC/flu were stained with CD8 antibody, influenza-M1 specific dextramer and IFNγ antibody. The original PBMC population was used as the comparison group. The upper panels shows CD8+ cells that are gated on M1+ staining. The lower panels show M1+ cells that are gated on IFNγ + cells.Back to article page
