Figure 4.
Intracellular cytokine staining of CD8+DILs after restimulation with mature DCs alone (mDC) or WT1 mRNA-electroporated DCs (mDC WT1). The WT1-specific T-cell cytokine response was evaluated by comparing mDC WT1 with mDC (all patients examined: UPN03, 05, 06, 08, 14, 17, 21, 22, 29, 30, 34, 35, and 47; long-term [LT] survivors: UPN06, 08, 14, 17, 21, 22, 29, 34, and 35; non-LT survivors: UPN03, 05, 30, and 47). IFN-γ+, interleukin-5+ (IL-5+), or TNF-α+ CD8+ T cells are shown for all patients (A), LT survivors (B), and non-LT survivors (C). Polyfunctional TNF-α+/IFN-γ+ CD8+ T cells are shown in the same patients (D).
