The invention discloses a CRISPR (clustered regularly interspaced short palindromic repeat) / Cas9 recombinant lentiviral vector containing gRNA sequence specifically targeting CCR5 and application thereof. A lentivirus of the CRISPR / Cas9 recombinant lentiviral vector containing gRNA sequence specifically targeting CCR5 gene Delta 32 region is constructed that the lentivirus can introduce cells into a CRISPR / Cas9 system specific to CCR5, double-chain breakage occurs to a specific site of CCR5 gene, a random mutation is introduced to a breakage site after repairing by means of nonhomogeneous recombinant terminal binding, and the mutation rate reaches 90% and above. As gRNA is a nonhomogeneous region of CCR5 and CCR2, detection shows that the missing efficiency of the two gRNAs is lower than 0.2%. Cells modified via the recombinant lentivirus have significantly decreased efficiency of HIV (human immunodeficiency virus) infection. The system is quick to construct, simple and low in price, and is applicable to gene therapy of acquired immune deficiency syndrome.
