摘要： The present disclosure belongs to the technical field of African swine fever (ASF) treatment, in particular to use of a compound aprepitant in prevention or treatment of the ASF. In the present disclosure, it is found that the compound aprepitant can significantly inhibit replication of an African swine fever virus (ASFV); in addition, it is found that the aprepitant inhibits transcription and protein expression of D1133L, and reduces transcription and protein expression levels of p30 and p72, preventing virus invasion on host cells. Therefore, the compound aprepitant can be used to inhibit early and late infection of the ASFV. Accordingly, the compound aprepitant can be used to prevent or treat the ASF.

摘要： The present disclosure belongs to the technical field of biology, and in particular relates to an attenuated strain of African swine fever virus (ASFV) with IPTG-induced deletion of a D1133L gene and use thereof. In the present disclosure, it is firstly found that the D1133L protein of ASFV can inhibit production of IFN-β and downstream cytokines ISG-15 and ISG-56, and can be used as an immunosuppressant with a relatively strong immunosuppressive effect. In addition, the attenuated strain of ASFV with IPTG-induced deletion of the D1133L gene is constructed. Specifically, a screening expression cassette is inserted into a position before the non-structural protein gene D1133L of the ASFV using an Escherichia coli lac operator-repressor system, to obtain a recombinant virus. In the presence of the IPTG, the recombinant virus has similar characteristics to a wild-type virus; and in the absence of the IPTG, the expression of the D1133L protein is inhibited.

摘要： The present disclosure belongs to the technical field of biological products for veterinary medicine, and specifically relates to a recombinant foot-and-mouth disease virus (FMDV) with a reduced immunosuppressive activity, a preparation method and use thereof, and a recombinant vaccine strain. According to the present disclosure, it is firstly discovered that FMDV 3B protein has an immunosuppressive function, and key sites for exerting the immunosuppressive function are found. A recombinant FMDV vaccine strain with a lost immunosuppressive function in FMDV 3B protein is constructed by introducing amino acid mutations into three repeated copies of FMDV 3B protein.

摘要： The present disclosure relates to a foot-and-mouth disease virus vaccine composition, especially a recombinant bivalent vaccine composition against type O and type A foot-and-mouth disease viruses. The present disclosure further relates to a method for preparing the foot-and-mouth disease virus vaccine composition, and a use of the foot-and-mouth disease virus vaccine composition in preparing medicines for preventing and/or controlling foot-and-mouth disease in animals.
