[Retracted] HD-13 Induces Swine Pneumonia Progression via Activation of TLR9

Figure 1

HD-13 activates TLR9 expression. (a) RT-qPCR was performed to assess TLR expression in 3D4/21 cells, following HD-13 infection at 0 h, 1 h, 4 h, 8 h, 12 h, 24 h, and 48 h, respectively. (b) RT-qPCR was conducted to assess TLR expression in the spleen of pig, following HD-13 infection at 0 h, 12 h, 24 h, 36 h, and 48 h, respectively. (c) Western blot was carried out to detect TLR9 expression in 3D4/21 cells, following HD-13 infection at 0 h, 1 h, 4 h, 12 h, 24 h, and 48 h, respectively. (d) Immunofluorescence was performed to assess TLR9 expression in 3D4/21 cells. , vs. control group.
