    • The molecular cloning and characterization of a novel human retrovirus, designated lymphadenopathy-associated virus, or LAV, is disclosed. LAV was originally isolated from a patient with acquired immune deficiency syndrome (AIDS). A cloned LAV complementary DNA (cDNA) was used to screen a library of recombinant phages constructed from the genomic DNA of LAV-infected T lymphocytes. The nucleotide sequence of an insert obtained from the recombinant phage clone &lgr;J19 was ascertained through M13 shotgun cloning and the dideoxy chain termination sequencing method. The env coding region was identified and peptides obtained therefrom. These peptides correspond to amino acids 239-294, 273-317, 300-327, 334-381, 397-424, and 466-500 of the LAV env. These peptides provide suitable diagnostic reagents for the detection LAV-specific antibodies and for the generation of LAV-specific immunological reagents.
    • 公开了一种新型人类逆转录病毒(称为淋巴结病相关病毒)或LAV的分子克隆和表征。 LAV最初与获得性免疫缺陷综合征(AIDS)的患者分离。 使用克隆的LAV互补DNA(cDNA)筛选由LAV感染的T淋巴细胞的基因组DNA构建的重组噬菌体文库。 通过M13霰弹枪克隆和双脱氧链终止测序方法确定从重组噬菌体克隆lambdJ19获得的插入物的核苷酸序列。 鉴定了env编码区和从其获得的肽。 这些肽对应于LAV环境的氨基酸239-294,273-317,300-327,334-381,397-424和466-500。 这些肽为检测LAV特异性抗体和产生LAV特异性免疫试剂提供合适的诊断试剂。
