    • The present invention relates to a novel human immunodeficiency virus (HIV) capable of inducing lymphadenopathies (LAS) and acquired immune deficiency syndromes (AIDS) in patients which has been designated the lymphadenopathy associated virus strain MAL (LAVMAL). Although the overall genomic organization of LAVMAL is similar to other known HIV-1 isolates such as LAVBRU and HTLV-III, nevertheless, this virus also displays considerable genotypic and phenotypic diversity as compared to these isolates. A proviral molecular clone of the virus was obtained and characterized. The complete nucleotide sequence of this clone was ascertained and putative regulatory regions (e.g., U3, R, U5,), regulatory elements (e.g., the TATA box, AATAAA polyadenylation signal, primer binding site), and open reading frames (e.g., Gag, Pol, Env, Vif, Vpr, Tat, Rev, Nef) identified. Of particular interest are unique polypeptides derived from the viral envelope. The claimed invention is directed toward isolated LAVMAL Env polypeptides consisting of 5-150 amino acids wherein said peptides contain a LAVMAL-specific epitope. These peptides will prove useful, inter alia, as diagnostic reagents and in the generation of immunological reagents for the detection of the virus.
    • 本发明涉及能够诱导淋巴结病变(LAS)和获得性免疫缺陷综合征(AIDS)的新型人类免疫缺陷病毒(HIV),其已被称为淋巴结病病毒相关病毒株MAL(LAVMAL)。 尽管LAVMAL的整体基因组组织与其他已知的HIV-1分离株如LAVBRU和HTLV-III相似,但是与这些分离株相比,该病毒也显示出相当大的基因型和表型多样性。 获得病毒的前病毒分子克隆并进行表征。 确定了该克隆的完整核苷酸序列,并推定了调控区(如U3,R,U5),调控元件(如TATA盒,AATAAA多聚腺苷酸化信号,引物结合位点)和开放阅读框(如Gag ,Pol,Env,Vif,Vpr,Tat,Rev,Nef)。 特别感兴趣的是衍生自病毒包膜的独特多肽。 所要求保护的发明涉及由5-150个氨基酸组成的分离的LAVMAL Env多肽,其中所述肽含有LAVMAL特异性表位。 这些肽尤其可用作诊断试剂和产生用于检测病毒的免疫试剂。
