This invention provides a chimeric adenovirus vector Ad5F35 and a recombinant CCR5-32 mutant gene, its construction method, and its application, belonging to the field of gene therapy technology. The construction method provided by this invention includes the following steps: (1) inserting the CCR5Δ32 mutant gene into the multiple cloning site of a shuttle vector to obtain a shuttle plasmid; (2) co-transfecting cells with the shuttle plasmid and the Ad5F35 adenovirus backbone plasmid to generate an Ad5F35 chimeric recombinant adenovirus capable of expressing the CCR5Δ32 gene. By inducing the inability of the CCR5 protein on the host cell to be normally expressed on the cell membrane surface, the binding of HIV-1 gp 120 to the CCR5Δ32 mutant gene is effectively prevented, thus preventing the HIV-1 virus from entering the host cell for replication, thereby achieving the goal of treating AIDS.
