    Three distinct genes in human DNA related to the transforming genes of mammalian sarcoma retroviruses (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1981-07-10
    Beschreibung: Southern blot hybridization was used to identify human and other vertebrate DNA sequences that were homologous to cloned DNA fragments containing the oncogenic nucleic acid sequences of three different type C mammalian retroviruses (simian sarcoma virus, the Snyder-Theilen strain of feline sarcoma virus, and the Harvey strain of murine sarcoma virus). Each onc gene counterpart has a single genetic locus, which probably contains non-onc intervening sequences. The human DNA sequences may represent genes important to cell growth or cell differentiation, or both. Their identification and isolation may allow elucidation of their role in these processes and in neoplasias.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wong-Staal, F -- Dalla-Favera, R -- Franchini, G -- Gelmann, E P -- Gallo, R C -- New York, N.Y. -- Science. 1981 Jul 10;213(4504):226-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6264598" target="_blank"〉PubMed〈/a〉

    A new subtype of human T-cell leukemia virus (HTLV-II) associated with a T-cell variant of hairy cell leukemia (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1982-11-05
    Beschreibung: Human T-cell leukemia virus (HTLV) is a human type-C RNA tumor virus (retrovirus) previously identified in and isolated from several patients with T-cell leukemias or lymphomas. The known virus isolates from the United States and Japan are closely related and are found in adults with an acute malignancy of mature T cells. A related retrovirus has been found in a patient (Mo) with a somewhat different disease (a T-cell variant of relatively benign hairy cell leukemia). Serum from Mo contains antibodies to the major internal core protein (p24) of HTLV. A T-cell line established from the spleen of Mo expresses HTLV antigens. However, HTLV from Mo is significantly different from all previous HTLV isolates in immunological cross-reactivity tests of p24. The usual prototype HTLV isolate is represented as HTLV-I, and the HTLV from Mo is represented as HTLV-II. Individual members of each subgroup may then be identified by subscript initials of the patient [for example, HTLV-I(CR), HTLV-I(MB), and HTLV-II(Mo)].〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kalyanaraman, V S -- Sarngadharan, M G -- Robert-Guroff, M -- Miyoshi, I -- Golde, D -- Gallo, R C -- New York, N.Y. -- Science. 1982 Nov 5;218(4572):571-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6981847" target="_blank"〉PubMed〈/a〉

    Natural antibodies to human retrovirus HTLV in a cluster of Japanese patients with adult T cell leukemia (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1982-02-19
    Beschreibung: Human T cell lymphoma leukemia virus (HTLV) is a human retrovirus (RNA tumor virus) that was originally isolated from a few patients with leukemias or lymphomas involving mature T lymphocytes. Here we report that the serum of Japanese patients with adult T cell leukemia, but not the serum of tested normal donors, contains high titers of antibodies to HTLV. These observations, together with data from Japan showing that adult T cell leukemia is endemic in southwest Japan, suggest that HTLV is involved in a subtype of human T cell malignancy, including Japanese adult T cell leukemia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Robert-Guroff, M -- Nakao, Y -- Notake, K -- Ito, Y -- Sliski, A -- Gallo, R C -- New York, N.Y. -- Science. 1982 Feb 19;215(4535):975-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6760397" target="_blank"〉PubMed〈/a〉

    Proviral DNA of a retrovirus, human T-cell leukemia virus, in two patients with AIDS (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1983-05-20
    Beschreibung: The acquired immune deficiency syndrome (AIDS) is characterized by T-lymphocyte dysfunction and is frequently accompanied by opportunistic infections and Kaposi's sarcoma. Human T-cell leukemia virus (HTLV) is associated with T-cell malignancies and can transform T lymphocytes in vitro. In an attempt to find evidence of HTLV infection in patients with AIDS, DNA from samples of peripheral blood lymphocytes from 33 AIDS patients was analyzed by Southern blot-hybridization with a radiolabeled cloned HTLV DNA probe. Analysis of DNA from both the fresh (uncultured) lymphocytes and from T cells cultured with T-cell growth factor revealed the presence of integrated HTLV proviral sequences in lymphocytes from two of the patients, both of whom had antibody to HTLV. The proviral sequences could not be detected in blood samples obtained from these individuals at a later date, consistent with the possibility that the population of infected cells had become depleted.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gelmann, E P -- Popovic, M -- Blayney, D -- Masur, H -- Sidhu, G -- Stahl, R E -- Gallo, R C -- New York, N.Y. -- Science. 1983 May 20;220(4599):862-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6601822" target="_blank"〉PubMed〈/a〉

    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
    Publikationsdatum: 1984-11-02
    Beschreibung: 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〉

    T-cell growth factor gene: lack of expression in human T-cell leukemia-lymphoma virus-infected cells (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1984-03-09
    Beschreibung: Activated mature T cells require T-cell growth factor (TCGF) for continuous proliferation. However, many mature T cells infected with human T-cell leukemia-lymphoma virus grow independently of exogenously added TCGF. It is now reported that cells infected with this virus also lack detectable TCGF messenger RNA (less than one copy per cell) and thus do not produce their own growth factor. The results apparently rule out an autostimulation mechanism of growth control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arya, S K -- Wong-Staal, F -- Gallo, R C -- New York, N.Y. -- Science. 1984 Mar 9;223(4640):1086-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6320374" 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
    Publikationsdatum: 1984-08-31
    Beschreibung: 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〉

    Frequent detection and isolation of cytopathic retroviruses (HTLV-III) from patients with AIDS and at risk for AIDS (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1984-05-04
    Beschreibung: Peripheral blood lymphocytes from patients with the acquired immunodeficiency syndrome (AIDS) or with signs or symptoms that frequently precede AIDS (pre-AIDS) were grown in vitro with added T-cell growth factor and assayed for the expression and release of human T-lymphotropic retroviruses (HTLV). Retroviruses belonging to the HTLV family and collectively designated HTLV-III were isolated from a total of 48 subjects including 18 of 21 patients wih pre-AIDS, three of four clinically normal mothers of juveniles with AIDS, 26 of 72 adult and juvenile patients with AIDS, and from one of 22 normal male homosexual subjects. No HTLV-III was detected in or isolated from 115 normal heterosexual subjects. The number of HTLV-III isolates reported here underestimates the true prevalence of the virus since many specimens were received in unsatisfactory condition. Other data show that serum samples from a high proportion of AIDS patients contain antibodies to HTLV-III. That these new isolates are members of the HTLV family but differ from the previous isolates known as HTLV-I and HTLV-II is indicated by their morphological, biological, and immunological characteristics. These results and those reported elsewhere in this issue suggest that HTLV-III may be the primary cause of AIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gallo, R C -- Salahuddin, S Z -- Popovic, M -- Shearer, G M -- Kaplan, M -- Haynes, B F -- Palker, T J -- Redfield, R -- Oleske, J -- Safai, B -- New York, N.Y. -- Science. 1984 May 4;224(4648):500-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6200936" 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)

    Beschreibung: 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〉

    Antigens encoded by the 3'-terminal region of human T-cell leukemia virus: evidence for a functional gene (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1984-10-05
    Beschreibung: Antibodies in sera from patients with adult T-cell leukemia-lymphoma or from healthy carriers of type I human T-cell leukemia virus (HTLV) recognize an antigen of approximately 42 kilodaltons (p42) in cell lines infected with HTLV-I. Radiolabel sequence analysis of cyanogen bromide fragments of p42 led to the conclusion that this antigen is encoded in part by LOR, a conserved portion of the "X" region that is flanked by the envelope gene and the 3' long terminal repeat of HTLV-I. It is possible that this novel product mediates the unique transformation properties of the HTLV family.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, T H -- Coligan, J E -- Sodroski, J G -- Haseltine, W A -- Salahuddin, S Z -- Wong-Staal, F -- Gallo, R C -- Essex, M -- 2-T32-CA0903/CA/NCI NIH HHS/ -- CA07094/CA/NCI NIH HHS/ -- CA13885/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1984 Oct 5;226(4670):57-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6089350" target="_blank"〉PubMed〈/a〉
