Figure 7

Chickens in groups ALV–TPPPS (red) and ALV (blue) were orally administered for 2 weeks with TPPPS and PBS, respectively. Non-infected chickens treated with PBS served as group Mock (black). The fresh anti-coagulated peripheral bloods and sera were isolated from three chickens in each group at 7, 14, 21, 28, 35, 42, and 49 dph. The percentages of CD4+ (A) and CD8+ (B) T lymphocytes were detected using flow cytometry. Lymphocyte proliferation (C) was detected through the MTT assay. The concentrations of IL-2 (D) and IFN-γ (E) in sera were determined by ELISA. The anti-ND antibody titers (F) were determined by performing the HI test. All values shown are expressed as means ± SD. An asterisk indicates that the value of the corresponding group was significantly different from that of the control group (P < 0.05).
