FIG 6.

ChinaGD01 infection did not induce robust virus-specific T cell responses in mice. BALFs from ChinaGD01 or EMC/2012 infected mice were harvested at day 7 p.i. Virus-specific T cells were stimulated with T cell epitope peptides. IFN-γ and TNF productions were measured by intracellular cytokine staining. Representative flow plots for virus-specific CD4⁺ and CD8⁺ T cells are shown (A and B). Frequencies of IFN-γ⁺ CD4⁺ or CD8⁺ T cells are shown (C and D). Data are representative of those from two independent experiments.
