Host immune responses in C57Bl/6 syngeneic murine models. Percentage of (A) CD19+ B cells, (B) CD3+ T cells (C) CD8+ CD3+ T cells (D) gp100+ CD8+ T cells (E) TRP-2+ CD8+ T cells (F) CD86+ CD11c+ cells (G) CD80+ CD11c+ cells (H) CD11c+ CD3− cells in lymph nodes (tumor-draining and non-draining) which were processed into single-cell suspensions, stained with antibodies and analyzed by flow cytometry. Error bars, SE **,*p < 0.05. Mock (PBS), dendritic cells (DCs) alone, Ad5/3-CMV-mCD40L (Ad) alone and Ad5/3-CMV-mCD40L plus DCs (Ad+ DCs).
