Enhancement of CTLs induced by DCs loaded with ubiquitinated hepatitis B virus core antigen

Figure 6 Intracellular cytokine analysis. A: The proliferative T cells were suspended in complete RPMI 1640 (2 × 10⁶/mL), Intracellular cytokine analysis by flow cytometry using CD8α-FITC and Interferon (IFN)-γ-PE antibodies. The results are representative of one of three experiments; B: The presence of CD8α⁺ and IFN-γ⁺ cells . ^bP < 0.01 vs lentiviral vector-encoding hepatitis B virus core antigen (LV-HBcAg) group. LV-Ub-HBcAg: Lentiviral vector-encoding ubiquitinated hepatitis B virus core antigen; LV-HBcAg: Lentiviral vector-encoding hepatitis B virus core antigen; LV: Lentiviral vector.
