Schematic diagram of the working model of the LSDV ORF142 protein negatively regulating IFN-I production. The LSDV ORF142 protein inhibits the phosphorylation of IRF3 by interacting with IRF3 and disrupting the interaction between TBK1 and IRF3, thereby inhibiting the production of IFN-I. Both wild-type LSDV and ORF142 proteins allow the virus to evade innate immunity by inhibiting the binding of TBK1 and IRF3. The diagram was created using Figdraw (https://www.figdraw.com/)
