This invention is in the field of lymphadenopathy virus, which has been designated Human Immunodeficiency Virus (HIV). This invention relates to a diagnostic means and method to detect the presence of DNA, RNA or antibodies of the lymphadenopathy retrovirus associated with the acquired immune deficiency syndrome or of the lymphadenopathy syndrome by the use of DNA fragments or the peptides encoded by said DNA fragments. The invention further relates to the DNA fragments, vectors comprising them and the proteins expressed.

Human deficiency virus type-1 (HIV-1) peptide encoded by the VIF gene

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.

Peptides of human immunodeficiency virus type 1 (HIV-1)

This invention is in the field of lymphadenopathy virus which has been desogmated Human Immunodeficiency Virus Type 1 (HIV-1) This invention relates to a diagnostic means and method to detect the presence of DNA, RNA or antibodies of the lymphadenopathy retrovirus associated with the acquired immune deficiency syndrome or of the lymphadenopathy syndrome by the use of DNA fragments or the peptides encoded by said DNA fragments.

Amino acid DNA sequences related to genomic RNA of human

The complete nucleotide sequence of a proviral molecular clone of the lymphadenopathy-associated virus, LAV, was ascertained. Recombinant phage clones were isolated from a genomic library of LAV-infected human T-lymphocyte DNA. The insert of recombinant phase .lambda.J19 was sequenced according to the dideoxy chain termination method. In addition to the retroviral structural genes gag, pol, and env, a novel open reading frame (ORF) was identified in the 3' region of the viral genome and designated ORF-R. The ORF-R coding region, which has subsequently been renamed nef, encodes a 206 amino acid protein that slightly overlaps the 3' end of the env gene and the 5' portion of the U3 region of the viral long terminal repeat (LTR). Nucleic acids encoding this protein and the precise amino acid sequence of the Nef are disclosed in this application. These products are useful for the generation of immunological reagents to facilitate the detection of LAV.
