Fig. 7From: The role of IBV PL1pro in virus replication and suppression of host innate immune responsesOverexpression of IBV PL1pro-N downregulates the expressions of IFN-β, p-STAT1, IFIT1, and IFIT2 in cells. H1299 cells were overexpressed with IBV PL1pro-N, then infected with rIBV. Western blot was performed to analyze IFN-β, p-STAT1, IFIT1, and IFIT2 protein expressions.
