The invention relates to a method for successfully inducing cell chemokine receptor CCR5 genes to be mutated into CCR5-delta32 deletion-type genes with a new genome editing technology CRISPR-Cas9. CCR5 is an important receptor for human immunodeficiency viruses (HIV) to invade personal host cells. CCR5-delta32 deletion means deletion of 32 basic groups occurs in a CCR5 coding region, so that the sequence after the 185th amino acid is changed, and early termination occurs. CCR5-delta32 biallelic-gene homozygous deletion has natural resistance to HIV infection, and can not be infected by HIV. By means of the method, a slow virus packaging system and the CRISPR technology are used at the same time; as the slow virus infecting host range is wide, the method can be applied to cells such as bone marrow stem cells and CD4T cells, and the CCR5-delta32 deletion-type genes hopefully become medicine for treating acquired immune deficiency syndrome or other diseases.
