After adoptive transfer of CD4+ T cells, the levels of IFN-γ and IL-2 of CD4+T+rEg.P29+CpG+Infection group were significantly increased, but the levels of TNF-α, IL-6, and IL-10 showed no difference compared with those of the CD4+ T+PBS+Infection group and CD4+ T+CpG+Infection (Figure 5F‒J). The gene discussed is IFNG; the disease is infection.
