The antiviral action of BLP in vivo and in vitro. A Effect of BLP on ALV gp85 gene relative expression measured by qRT-PCR in different tissues in vivo at 42 d of age (Log2). B Influence of BLP on the expression of p27 antigen at different stages of virus infection in vitro (mean ± SE). The groups in the figure were cell control (CC), ALV control (AC), ALV infection 2 h before BL21 supernatant incubation (AS), ALV infection 2 h before BLP incubation (AB), BLP incubation 2 h before ALV infection (BA), ALV and BLP together (A&B). The final concentrations of BLP were all 50 μg/mL in these three administrations (AB, BA, A&B). C ALV gp85 gene relative expression in different groups measured with qRT-PCR in vitro (Log2). DF-1 cells with or without ALV inoculation were used as ALV control (AC) and cell control (CC), respectively. The different lowercases and capitals indicated significant difference at level of P < 0.05 and P < 0.01. Data were expressed from three independent experiments
