The expression levels of endogenous TPL2 and viral proteins were detected by Western blotting with anti-TPL2 and anti-FMDV antibodies. (C) The mRNA expression levels of p105 and ABIN2 were measured by RT-qPCR for the samples from panel A. (D) The expression levels of endogenous p105, ABIN2, and viral proteins were detected by Western blotting for the samples from panel B with anti-p105, anti-ABIN2, and anti-FMDV antibodies.
