The mechanism of leukaemogenic transformation by human T-cell leukaemia/lymphoma virus (HTLV), a retrovirus implicated in the aetiology of certain adult T-cell leukaemias and lymphomas, is unknown but is conceivably associated with the expression of the cellular analogues of retroviral oncogenes. The HUT-102 cell line, derived from a cutaneous T-cell(More)
A fundamental step in the replication of retroviruses is the reverse transcription of the viral RNA genome into a double-stranded DNA provirus. Retroviruses are believed to carry genomic information only as RNA, and synthesis of DNA is thought to start only after virus entry into the infected cell. We report here that infectious mature human(More)
The characterization of HIV-1 (HTLV-III/LAV), the human retrovirus associated with AIDS (acquired immune deficiency syndrome) has led to the identification of a group of related human and simian retroviruses which also infect CD4-bearing T lymphocytes. Simian T-lymphotropic virus type III (simian immodeficiency virus) from macaques (STLV-IIIMAC) induces(More)
Transmission and growth of HIV-1 produced from the biologically active clone HTLV-III/HXB2D in the constant presence of a neutralizing antiserum yielded a viral population specifically resistant to neutralization by the same antiserum. Molecular clones MX-1 and -2, containing the entire envelope gene, were obtained from cultures of the resistant variant.(More)
The nucleotide sequence of a transforming human c-sis complementary DNA shows an open reading frame 723 base pairs in length located downstream from an in-phase terminator thymine-guanine-adenine codon. Sequences within this region were identical to those previously determined for the exons of the normal human c-sis gene. Thus, the predicted transforming(More)
An immunotoxin has been made by coupling anti-human immunodeficiency virus (HIV) envelope antibody 907 to ricin A chain (907-RAC). 907 recognizes an epitope within the immunodominant PB-1 loop of gp120. Variant cells were selected by cloning persistently infected H9/human T lymphocyte virus IIIB cells in the presence of the immunotoxin. Clones resistant to(More)
Human T-cell leukaemia/lymphoma virus (HTLV) can be identified in fresh and cultured T-lymphocytes from patients with adult T-cell malignancies. HLA typing of the peripheral blood lymphocytes and cultured cell lines from the patient from which the virus was originally isolated suggested the expression of additional HLA-A and -B locus antigens on the HTLV(More)
Human T-cell leukaemia virus (HTLV), first isolated in the United States from a patient with cutaneous T-cell lymphoma, is a unique horizontally transmitted retrovirus which is highly associated with certain adult T-cell malignancies. Also, HTLV can be transmitted in vitro to cord blood T-lymphocytes. In the accompanying paper it was shown that all T cells(More)
