    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: In vitro and in vivo model systems for the study of human immunodeficiency virus (HIV)-associated Kaposi's sarcoma (KS) were used to evaluate compounds for their potential as therapeutic agents. A sulfated polysaccharide-peptidoglycan compound (SP-PG) produced by bacteria controlled the in vitro growth of acquired immunodeficiency syndrome (AIDS)-associated, KS-derived spindle-shaped cells (AIDS-KS cells) at noncytotoxic concentrations. Angiogenesis induced by AIDS-KS cells in the chicken chorioallantoic membrane assay was blocked by SP-PG, which also inhibited the vascular hyperpermeability response and the angiogenesis associated with the induction of KS-like lesions that develop after subcutaneous inoculation of AIDS-KS cells into nude mice. Suramin, pentosan polysulfate, and interferon alpha, which are currently in use for therapy of KS, were either less effective than SP-PG or much more cytotoxic, or both.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nakamura, S -- Sakurada, S -- Salahuddin, S Z -- Osada, Y -- Tanaka, N G -- Sakamoto, N -- Sekiguchi, M -- Gallo, R C -- New York, N.Y. -- Science. 1992 Mar 13;255(5050):1437-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Internal Medicine, University of Southern California, Los Angeles 90033.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1371891" target="_blank"〉PubMed〈/a〉

    Description: 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〉

    Description: Cell-free conditioned media from human T cells transformed by human T-cell leukemia-lymphoma virus (HTLV-I) were tested for the production of soluble biologically active factors, including several known lymphokines. The cell lines used were established from patients with T-cell leukemia-lymphoma and from human umbilical cord blood and bone marrow leukocytes transformed by HTLV-I in vitro. All of the cell lines liberated constitutively one or more of the 12 biological activities assayed. These included macrophage migration inhibitory factor (MIF), leukocyte migration inhibitory factor (LIF), leukocyte migration enhancing factor (MEF), macrophage activating factor (MAF), differentiation inducing factor (DIF), colony stimulating factor (CSF), eosinophil growth and maturation activity (eos. GMA), fibroblast activating factor (FAF), gamma-interferon and, in rare instances, T-cell growth factor (TCGF). Some cell lines produced interleukin 3 (IL-3), platelet-derived growth factor (PDGF), or B-cell growth factors (BCGF). Such cells should prove useful for the production of lymphokines and as sources of specific messenger RNA's for their genetic cloning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Salahuddin, S Z -- Markham, P D -- Lindner, S G -- Gootenberg, J -- Popovic, M -- Hemmi, H -- Sarin, P S -- Gallo, R C -- New York, N.Y. -- Science. 1984 Feb 17;223(4637):703-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6320367" target="_blank"〉PubMed〈/a〉

    Description: Nine new isolates of human T-cell leukemia-lymphoma virus (HTLV) were obtained from cells of seven patients with malignancies of mature T cells and from two clinically normal relatives of a T-cell leukemia patient. These people were from the United States, Israel, the West Indies, and Japan. The virus was detected in the fresh T cells and was isolated from the established T-cell lines. Each isolate is closely related to the first HTLV isolate, and all the new HTLV isolates were transmitted into normal human T cells obtained from the umbilical cord blood of newborns.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Popovic, M -- Sarin, P S -- Robert-Gurroff, M -- Kalyanaraman, V S -- Mann, D -- Minowada, J -- Gallo, R C -- New York, N.Y. -- Science. 1983 Feb 18;219(4586):856-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6600519" target="_blank"〉PubMed〈/a〉

    Description: The DNA genomes of human T-lymphotropic virus type III (HTLV-III) isolated from 18 individuals with AIDS or who were at risk for AIDS were evaluated for evidence of variation. Although all of the 18 viral DNA's hybridized throughout their entire genomes to a full-length cloned probe of the original HTLV-III isolate, each of the 18 isolates showed a different restriction enzyme pattern. The number of restriction site differences between isolates ranged from only 1 site in 23 to at least 16 sites in 31. No particular viral genotype was associated with a particular disease state and 2 of the 18 patients had evidence of concurrent infection by more than one viral genotype. Propagation of three different viral isolates in vitro for up to 9 months did not lead to detectable changes in their restriction patterns. These findings indicate that different isolates of HTLV-III comprise a spectrum of highly related but distinguishable viruses and have important implications regarding the pathogenicity of HTLV-III and attempts to develop effective diagnostic, therapeutic, and preventive measures for this virus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wong-Staal, F -- Shaw, G M -- Hahn, B H -- Salahuddin, S Z -- Popovic, M -- Markham, P -- Redfield, R -- Gallo, R C -- New York, N.Y. -- Science. 1985 Aug 23;229(4715):759-62.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2992084" target="_blank"〉PubMed〈/a〉

    Description: The genome of the human immunodeficiency virus HIV-1 contains at least eight genes, of which three (sor, R, and 3' orf) have no known function. In this study, the role of the sor gene was examined by constructing a series of proviral genomes of HIV-1 that either lacked the coding sequences for sor or contained point mutations in sor. Analysis of four such mutants revealed that although each clone could generate morphologically normal virus particles upon transfection, the mutant viruses were limited in their capacity to establish stable infection. Virus derived from transfection of Cos-1 cells (OKT4-) with sor mutant proviral DNA's was resistant to transmission to OKT4+ "susceptible" cells under cell-free conditions, and was transmitted poorly by coculture. In contrast, virus derived from clones with an intact sor frame was readily propagated by either approach. Normal amounts of gag-, env-, and pol-derived proteins were produced by all four mutants and assays in both lymphoid and nonlymphoid cells indicated that their trans-activating capacity was intact and comparable with wild type. Thus the sor gene, although not absolutely required in HIV virion formation, influences virus transmission in vitro and is crucial in the efficient generation of infectious virus. The data also suggest that sor influences virus replication at a novel, post-translational stage and that its action is independent of the regulatory genes tat and trs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fisher, A G -- Ensoli, B -- Ivanoff, L -- Chamberlain, M -- Petteway, S -- Ratner, L -- Gallo, R C -- Wong-Staal, F -- New York, N.Y. -- Science. 1987 Aug 21;237(4817):888-93.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3497453" target="_blank"〉PubMed〈/a〉

    Description: Long-term cultures were established of HTLV-III-infected T4 cells from patients with the acquired immune deficiency syndrome (AIDS) and of T4 cells from normal donors after infection of the cells in vitro. By initially reducing the number of cells per milliliter of culture medium it was possible to grow the infected cells for 50 to 60 days. As with uninfected T cells, immunologic activation of the HTLV-III-infected cells with phytohemagglutinin led to patterns of gene expression typical of T-cell differentiation, such as production of interleukin-2 and expression of interleukin-2 receptors, but in the infected cells immunologic activation also led to expression of HTLV-III, which was followed by cell death. The results revealed a cytopathogenic mechanism that may account for T4 cell depletion in AIDS patients and suggest how repeated antigenic stimulation by infectious agents, such as malaria in Africa, or by allogeneic blood or semen, may be important determinants of the latency period in AIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zagury, D -- Bernard, J -- Leonard, R -- Cheynier, R -- Feldman, M -- Sarin, P S -- Gallo, R C -- New York, N.Y. -- Science. 1986 Feb 21;231(4740):850-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2418502" target="_blank"〉PubMed〈/a〉
