    Transmission of HTLV-III infection from human plasma to chimpanzees: an animal model for AIDS (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-11-02
    Description: Two of three chimpanzees given plasma from patients with acquired immune deficiency syndrome (AIDS) or pre-AIDS showed serum antibodies to type III human T-cell leukemia virus (HTLV-III) 10 to 12 weeks after transfusion. One animal also developed lymphadenopathy, transient depression of the ratio of T4 to T8 lymphocytes, and impaired blastogenic responses. No opportunistic infections occurred. Adenopathy persisted for 32 weeks, and antibody to HTLV-III persisted for at least 48 weeks. This transmission of HTLV-III by lymphocyte-poor plasma confirms the potential risk of such plasma or plasma derivatives to recipients. The susceptibility of the chimpanzee to HTLV-III infection and the ability to simulate the human lymphadenopathy syndrome in this animal makes it a valuable model for further study of AIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alter, H J -- Eichberg, J W -- Masur, H -- Saxinger, W C -- Gallo, R -- Macher, A M -- Lane, H C -- Fauci, A S -- New York, N.Y. -- Science. 1984 Nov 2;226(4674):549-52.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6093251" target="_blank"〉PubMed〈/a〉

    Homology of genome of AIDS-associated virus with genomes of human T-cell leukemia viruses (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-08-31
    Description: A T lymphotropic virus found in patients with the acquired immune deficiency syndrome (AIDS) or lymphadenopathy syndrome has been postulated to be the cause of AIDS. Immunological analysis of this retrovirus and its biological properties suggest that it is a member of the family of human T-lymphotropic retroviruses known as HTLV. Accordingly, it has been named HTLV-III. In the present report it is shown by nucleic acid hybridization that sequences of the genome of HTLV-III are homologous to the structural genes (gag, pol, and env) of both HTLV-I and HTLV-II and to a potential coding region called pX located between the env gene and the long terminal repeating sequence that is unique to the HTLV family of retroviruses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arya, S K -- Gallo, R C -- Hahn, B H -- Shaw, G M -- Popovic, M -- Salahuddin, S Z -- Wong-Staal, F -- New York, N.Y. -- Science. 1984 Aug 31;225(4665):927-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6089333" target="_blank"〉PubMed〈/a〉

    HTLV-III in saliva of people with AIDS-related complex and healthy homosexual men at risk for AIDS (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-10-26
    Description: Peripheral blood leukocytes and saliva from 20 individuals, including four with the acquired immune deficiency syndrome (AIDS), ten with AIDS-related complex (ARC), and six healthy homosexual males at risk for AIDS, were compared as sources of transmissible human T-cell leukemia (lymphotropic) virus type III (HTLV-III), the virus found to be the etiologic agent of AIDS. All of the AIDS and ARC patients and four of the six healthy homosexuals had evidence of prior exposure to HTLV-III as indicated by seropositivity for antibody to HTLV-III structural proteins. Infectious virus was isolated from the peripheral blood of one of the AIDS patients, four of the ARC patients, and two of the healthy homosexual males, consistent with previous reports. HTLV-III was also isolated from the saliva of four of the ARC patients and four of the healthy homosexuals. Virus was also observed by electron microscopy in material prepared by centrifugation of the saliva of one AIDS patient. Although AIDS does not appear to be transmitted by casual contact, the possibility that HTLV-III can be transmitted by saliva should be considered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Groopman, J E -- Salahuddin, S Z -- Sarngadharan, M G -- Markham, P D -- Gonda, M -- Sliski, A -- Gallo, R C -- N0I-CO-23910/CO/NCI NIH HHS/ -- New York, N.Y. -- Science. 1984 Oct 26;226(4673):447-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6093247" target="_blank"〉PubMed〈/a〉

    Serological analysis of a subgroup of human T-lymphotropic retroviruses (HTLV-III) associated with AIDS (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-05-04
    Description: The two main subgroups of the family of human T-lymphotropic retroviruses (HTLV) that have previously been characterized are known as HTLV-I and HTLV-II. Both are associated with certain human leukemias and lymphomas. Cell surface antigens (p61 and p65) encoded by HTLV-I are frequently recognized, at low titers, by antibodies in the serum of patients with acquired immunodeficiency syndrome (AIDS) or with signs or symptoms that precede AIDS (pre-AIDS). This suggests an involvement of HTLV in these disorders. Another subgroup of HTLV, designated HTLV-III, has now been isolated from many patients with AIDS and pre-AIDS. In the studies described in this report, virus-associated antigens in T-cell clones permanently producing HTLV-III were subjected to biochemical and immunological analyses. Antigens of HTLV-III, specifically detected by antibodies in serum from AIDS or pre-AIDS patients and revealed by the Western blot technique, are similar in size to those found in other subgroups of HTLV. They include at least three serologically unrelated antigenic groups, one of which is associated with group-specific antigens (p55 and P24) and another with envelope-related (p65) proteins, while the antigens in the third group are of unknown affiliation. The data show that HTLV-III is clearly distinguishable from HTLV-I and HTLV-II but is also significantly related to both viruses. HTLV-III is thus a true member of the HTLV family.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schupbach, J -- Popovic, M -- Gilden, R V -- Gonda, M A -- Sarngadharan, M G -- Gallo, R C -- New York, N.Y. -- Science. 1984 May 4;224(4648):503-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6200937" target="_blank"〉PubMed〈/a〉

    Molecular characterization of human T-cell leukemia (lymphotropic) virus type III in the acquired immune deficiency syndrome (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-12-07
    Description: The human T-cell leukemia (lymphotropic) virus type III (HTLV-III) appears to be central to the causation of the acquired immune deficiency syndrome (AIDS). Two full-length integrated proviral DNA forms of HTLV-III have now been cloned and analyzed, and DNA sequences of the virus in cell lines and fresh tissues from patients with AIDS or AIDS-related complex (ARC) have been characterized. The results revealed that (i) HTLV-III is an exogenous human retrovirus, approximately 10 kilobases in length, that lacks nucleic acid sequences derived from normal human DNA; (ii) HTLV-III, unlike HTLV types I and II, shows substantial diversity in its genomic restriction enzyme cleavage pattern; (iii) HTLV-III persists in substantial amounts in cells as unintegrated linear DNA, an uncommon property that has been linked to the cytopathic effects of certain animal retroviruses; and (iv) HTLV-III viral DNA can be detected in low levels in fresh (primary) lymphoid tissue of a minority of patients with AIDS or ARC but appears not to be present in Kaposi's sarcoma tissue. These findings have important implications concerning the biological properties of HTLV-III and the pathophysiology of AIDS and Kaposi's sarcoma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shaw, G M -- Hahn, B H -- Arya, S K -- Groopman, J E -- Gallo, R C -- Wong-Staal, F -- New York, N.Y. -- Science. 1984 Dec 7;226(4679):1165-71.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6095449" target="_blank"〉PubMed〈/a〉

    Detection, isolation, and continuous production of cytopathic retroviruses (HTLV-III) from patients with AIDS and pre-AIDS (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-05-04
    Description: A cell system was developed for the reproducible detection of human T-lymphotropic retroviruses (HTLV family) from patients with the acquired immunodeficiency syndrome (AIDS) or with signs or symptoms that frequently precede AIDS (pre-AIDS). The cells are specific clones from a permissive human neoplastic T-cell line. Some of the clones permanently grow and continuously produce large amounts of virus after infection with cytopathic (HTLV-III) variants of these viruses. One cytopathic effect of HTLV-III in this system is the arrangement of multiple nuclei in a characteristic ring formation in giant cells of the infected T-cell population. These structures can be used as an indicator to detect HTLV-III in clinical specimens. This system opens the way to the routine detection of HTLV-III and related cytopathic variants of HTLV in patients with AIDS or pre-AIDS and in healthy carriers, and it provides large amounts of virus for detailed molecular and immunological analyses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Popovic, M -- Sarngadharan, M G -- Read, E -- Gallo, R C -- New York, N.Y. -- Science. 1984 May 4;224(4648):497-500.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6200935" target="_blank"〉PubMed〈/a〉

    Isolation of human T-cell leukemia virus in acquired immune deficiency syndrome (AIDS) (1983)

    Details
    Publication Date: 1983-05-20
    Description: Several isolates of a human type-C retrovirus belonging to one group, known as human T-cell leukemia virus (HTLV), have previously been obtained from patients with adult T-cell leukemia or lymphoma. The T-cell tropism of HTLV and its prevalence in the Caribbean basin prompted a search for it in patients with the epidemic T-cell immune deficiency disorder known as AIDS. Peripheral blood lymphocytes from one patient in the United States and two in France were cultured with T-cell growth factor (TCGF) an shown to express HTLV antigens. Virus from the U.S. patient was isolated and characterized and shown to be related to HTLV subgroup I. The virus was also transmitted into normal human T cells from umbilical cord blood of a newborn. Whether or not HTLV-I or other retroviruses of this family with T-cell tropism cause AIDS, it is possible that patients from whom the virus can be isolated can also transmit it to others. If the target cell of AIDS is the mature T cell as suspected, the methods used in these studies may prove useful for the long-term growth of these cells and for the identification of antigens specific for the etiological agent of AIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gallo, R C -- Sarin, P S -- Gelmann, E P -- Robert-Guroff, M -- Richardson, E -- Kalyanaraman, V S -- Mann, D -- Sidhu, G D -- Stahl, R E -- Zolla-Pazner, S -- Leibowitch, J -- Popovic, M -- New York, N.Y. -- Science. 1983 May 20;220(4599):865-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6601823" target="_blank"〉PubMed〈/a〉

    HTLV-III in cells cultured from semen of two patients with AIDS (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-10-26
    Description: Epidemiological results suggest that the etiological agent of the acquired immune deficiency syndrome (AIDS) is transmitted primarily through blood products, semen, and saliva. There is evidence that the human T-cell leukemia (lymphotropic) virus type III (HTLV-III) is this agent. HTLV-III has been isolated repeatedly from T cells obtained from peripheral blood or lymph node tissue of AIDS and pre-AIDS patients and of healthy people believed to have been exposed to the virus. In the present study, HTLV-III was detected in and isolated from T cells present in the seminal fluid of AIDS patients. Mononuclear cells from the semen of AIDS patients and normal individuals were cultured in the presence of T-cell growth factor (interleukin-2). After 6 to 8 days, HTLV-III antigens were transiently expressed by the cells from the AIDS patients but not by those from the normal individuals. When the mononuclear cells from the semen of AIDS patients were cocultured with a permissive human T-cell line, cell cultures were produced that expressed high levels of reverse transcriptase activity, showed retroviral particles by electron microscopy, and were positive for HTLV-III-specific antigens when tested by fixed-cell indirect immunofluorescence with the use of monoclonal antibodies to the p24 and p15 antigens of HTLV-III.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zagury, D -- Bernard, J -- Leibowitch, J -- Safai, B -- Groopman, J E -- Feldman, M -- Sarngadharan, M G -- Gallo, R C -- New York, N.Y. -- Science. 1984 Oct 26;226(4673):449-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6208607" target="_blank"〉PubMed〈/a〉
