Figure 3. Induction and activation of NK cells and the increasing of IFN-γ⁺ cytotoxic T cells.

a. A splenic single cell suspension was analyzed by flow cytometry for the presence of activated NK cells CD49b⁺CD107a⁺. The increase of CD4⁺IFN-γ⁺ b. and CD8⁺IFN-γ⁺ c. cytotoxic T cells were examined with quantitative flow cytometry (^**P < 0.01, ^***P < 0.001, versus NS; ^†P < 0.05, ^††P < 0.01, versus PLP/pIL15; mean ± SD, n=3).
