Bovine leukemia virus (BLV) causes enzootic leukemia - a chronic infectious disease occurring against the background of embedding the virus in the genome of B-lymphocytes and leading to malignization, invasion of tumor cells in organs and the formation of tumors. The disease is common in the United States, Japan, and Asia. In Russia, up to 30% is infected with BLV. Moreover, there is evidence of the presence of antibodies to the BLV virus in some groups of people, and the relationship between BLV and cancer in humans is widely discussed. All this indicates an urgent need to study BLV and create breeds resistant to it. The development of approaches to solving this problem is complicated by the fact that the receptor through which the infection is carried out is still unknown. Recently, it has been suggested that the virus penetrates the animal's lymphocytes using the CD209 molecule. In this paper, we propose a genome editing system based on CRISPR/Cas9 to get a knockout for this gene. We assume that animals obtained using the presented genome editing system will be resistant to infection with the bovine leukemia virus.
