    Description: CD8(+) T lymphocytes from individuals infected with human immunodeficiency virus-type 1 (HIV-1) secrete a soluble activity that suppresses infection by HIV-1. A protein associated with this activity was purified from the culture supernatant of an immortalized CD8(+) T cell clone and identified as the beta-chemokine macrophage-derived chemokine (MDC). MDC suppressed infection of CD8(+) cell-depleted peripheral blood mononuclear cells by primary non-syncytium-inducing and syncytium-inducing isolates of HIV-1 and the T cell line-adapted isolate HIV-1IIIB. MDC was expressed in activated, but not resting, peripheral blood mononuclear cells and binds a receptor on activated primary T cells. These observations indicate that beta-chemokines are responsible for a major proportion of HIV-1-specific suppressor activity produced by primary T cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pal, R -- Garzino-Demo, A -- Markham, P D -- Burns, J -- Brown, M -- Gallo, R C -- DeVico, A L -- N01-AI-55279/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1997 Oct 24;278(5338):695-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Advanced BioScience Laboratories, 5510 Nicholson Lane, Kensington, MD 20895, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9381181" target="_blank"〉PubMed〈/a〉

    Description: Evidence suggests that CD8+ T lymphocytes are involved in the control of human immunodeficiency virus (HIV) infection in vivo, either by cytolytic mechanisms or by the release of HIV-suppressive factors (HIV-SF). The chemokines RANTES, MIP-1 alpha, and MIP-1 beta were identified as the major HIV-SF produced by CD8+ T cells. Two active proteins purified from the culture supernatant of an immortalized CD8+ T cell clone revealed sequence identity with human RANTES and MIP-1 alpha. RANTES, MIP-1 alpha, and MIP-1 beta were released by both immortalized and primary CD8+ T cells. HIV-SF activity produced by these cells was completely blocked by a combination of neutralizing antibodies against RANTES, MIP-1 alpha, and MIP-1 beta. Recombinant human RANTES, MIP-1 alpha, and MIP-1 beta induced a dose-dependent inhibition of different strains of HIV-1, HIV-2, and simian immunodeficiency virus (SIV). These data may have relevance for the prevention and therapy of AIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cocchi, F -- DeVico, A L -- Garzino-Demo, A -- Arya, S K -- Gallo, R C -- Lusso, P -- New York, N.Y. -- Science. 1995 Dec 15;270(5243):1811-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Tumor Cell Biology, National Cancer Institute, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8525373" target="_blank"〉PubMed〈/a〉

    Description: Conditioned medium from human T cell leukemia virus type 2 (HTLV-II)-infected T cells supports the growth and long-term culture of cells derived from acquired immunodeficiency syndrome (AIDS)-associated Kaposi's sarcoma lesions (AIDS-KS cells). A protein of 30 kilodaltons was purified from conditioned medium that supports the growth of AIDS-KS cells. The amino-terminal sequence of this protein was identical to the amino-terminal sequence of Oncostatin M, a glycoprotein that inhibits the growth of a variety of cancer cells. Oncostatin M from conditioned medium stimulated a twofold increase in the growth of AIDS-KS cells at a concentration of less than 1 nanogram of the protein per milliliter of medium.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nair, B C -- DeVico, A L -- Nakamura, S -- Copeland, T D -- Chen, Y -- Patel, A -- O'Neil, T -- Oroszlan, S -- Gallo, R C -- Sarngadharan, M G -- N01-CO-74101/CO/NCI NIH HHS/ -- N01-CP-73723/CP/NCI NIH HHS/ -- New York, N.Y. -- Science. 1992 Mar 13;255(5050):1430-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Advanced BioScience Laboratories, Inc., Kensington, MD.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1542792" target="_blank"〉PubMed〈/a〉

    Description: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that is familial in 10% of cases. We have identified a missense mutation in the gene encoding fused in sarcoma (FUS) in a British kindred, linked to ALS6. In a survey of 197 familial ALS index cases, we identified two further missense mutations in eight families. Postmortem analysis of three cases with FUS mutations showed FUS-immunoreactive cytoplasmic inclusions and predominantly lower motor neuron degeneration. Cellular expression studies revealed aberrant localization of mutant FUS protein. FUS is involved in the regulation of transcription and RNA splicing and transport, and it has functional homology to another ALS gene, TARDBP, which suggests that a common mechanism may underlie motor neuron degeneration.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4516382/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4516382/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vance, Caroline -- Rogelj, Boris -- Hortobagyi, Tibor -- De Vos, Kurt J -- Nishimura, Agnes Lumi -- Sreedharan, Jemeen -- Hu, Xun -- Smith, Bradley -- Ruddy, Deborah -- Wright, Paul -- Ganesalingam, Jeban -- Williams, Kelly L -- Tripathi, Vineeta -- Al-Saraj, Safa -- Al-Chalabi, Ammar -- Leigh, P Nigel -- Blair, Ian P -- Nicholson, Garth -- de Belleroche, Jackie -- Gallo, Jean-Marc -- Miller, Christopher C -- Shaw, Christopher E -- 078662/Wellcome Trust/United Kingdom -- G0300329/Medical Research Council/United Kingdom -- G0500289/Medical Research Council/United Kingdom -- G0501573/Medical Research Council/United Kingdom -- G0600676/Medical Research Council/United Kingdom -- G0600974/Medical Research Council/United Kingdom -- G0900688/Medical Research Council/United Kingdom -- MC_G1000733/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2009 Feb 27;323(5918):1208-11. doi: 10.1126/science.1165942.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Clinical Neuroscience, King's College London, Medical Research Council (MRC) Centre for Neurodegeneration Research, Institute of Psychiatry, London SE5 8AF, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19251628" target="_blank"〉PubMed〈/a〉

    Description: 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〉

    Description: 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〉

    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〉

    Description: Antibodies reactive with proteins of human T-cell leukemia virus (HTLV) can be found in Old World monkeys. A T-lymphocyte cell line established from a seropositive baboon (Papio cynocephalus) was analyzed for the presence of viral DNA sequences. The provirus found in these cells was related to but distinct from HTLV subgroup I. These results add to recent evidence from human studies that HTLV represents a spectrum of infectious T-lymphotropic retroviruses that includes closely and distantly related members.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guo, H G -- Wong-Stall, F -- Gallo, R C -- New York, N.Y. -- Science. 1984 Mar 16;223(4641):1195-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6322297" target="_blank"〉PubMed〈/a〉

    Description: T-cell growth factor (TCGF) or interleukin-2 (IL-2), an immunoregulatory lymphokine, is produced by lectin- or antigen-activated mature T lymphocytes and in a constitutive manner by certain T-cell lymphoma cell lines. By means of a molecular clone of human TCGF and DNA extracted from a panel of somatic cell hybrids (rodent cells X normal human lymphocytes), the TCGF structural gene was identified on human chromosome 4. In situ hybridization of the TCGF clone to human chromosomes resulted in significant labeling of the midportion of the long arm of chromosome 4, indicating that the TCGF gene was located at band q26-28. Genomic DNA from a panel of hybrids prepared with HUT-102 B2 cells was examined with the same molecular clone. In this clone of cells, which produces human T-cell leukemia virus, the TCGF gene was also located on chromosome 4 and was apparently not rearranged. The homologous TCGF locus in the domestic cat was assigned to chromosome B1 by using a somatic cell hybrid panel that segregates cat chromosomes. Linkage studies as well as high-resolution G-trypsin banding indicate that this feline chromosome is partially homologous to human chromosome 4.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seigel, L J -- Harper, M E -- Wong-Staal, F -- Gallo, R C -- Nash, W G -- O'Brien, S J -- New York, N.Y. -- Science. 1984 Jan 13;223(4632):175-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6318318" target="_blank"〉PubMed〈/a〉

    Description: In a study of the immunologic significance of the genetic diversity present within single isolates of human immunodeficiency virus type 1 (HIV-1), the neutralization of viruses derived from molecular clones of the HIV-1 strain HTLV-IIIB by an extensive panel of sera was compared. Sera from HIV-1-infected patients and from goats immunized with polyacrylamide gel-purified HIV-1 envelope glycoprotein (gp120), native gp120, or gp120-derived recombinant peptides, showed marked heterogeneity in neutralizing activity against these closely related viruses. The change of a single amino acid residue in gp120 may account for such "clonal restriction" of neutralizing activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Looney, D J -- Fisher, A G -- Putney, S D -- Rusche, J R -- Redfield, R R -- Burke, D S -- Gallo, R C -- Wong-Staal, F -- New York, N.Y. -- Science. 1988 Jul 15;241(4863):357-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Viral Diseases, Walter Reed Army Institute of Research, Washington, DC 20307.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3388046" target="_blank"〉PubMed〈/a〉
