Abstract: 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-? 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.
