Abstract： 目的:克隆人CCR5Delta32基因并构建含目的基因的重组慢病毒载体pLenti-CCR5Delta32,用于获得性免疫缺陷综合征(AIDS)的基因治疗研究. 方法:从CCR5Delta32突变个体外周血单个核细胞(PBMCs)内提取人基因组DNA,利用PCR技术扩增CCR5Delta32全长基因,经EcoRI单酶切后与pUCm-T载体连接,随后转化感受态E.coli DH5α,提取质粒进行酶切鉴定及DNA测序. 再将鉴定正确的CCR5Delta32基因亚克隆至慢病毒载体pLenti6/V5-D-TOPO并进行酶切鉴定及DNA序列分析. 结果:经PCR扩增获得约650 bp的DNA片段,测序结果与GenBank上的序列完全一致,克隆的目的基因已经正确插入到慢病毒载体pLenti6/V5-D-TOPO中. 结论:成功克隆了人CCR5Delta32基因并构建了含目的基因的重组慢病毒载体pLenti-CCR5Delta32,为进一步AIDS基因治疗研究奠定基础.
