As shown in Figure 2 B and C, the molecular contents of sCD4 and sCD8 in the DuCV group at 8 to 16 dpi were highly significant ( P < 0.01) lower than those in the PBS group, 24 to 32 dpi was extremely significant ( P < 0.001) lower than that in the PBS group, the content of sCD8 in the 8 dpi PBS group was highly significant ( P < 0.01) higher than that in the DuCV group, and 16 to 32 dpi was extremely significant ( P < 0.001) higher than that in the DuCV group.
