    Interleukin-8 as a macrophage-derived mediator of angiogenesis (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-12-11
    Description: Angiogenic factors produced by monocytes-macrophages are involved in the pathogenesis of chronic inflammatory disorders characterized by persistent angiogenesis. The possibility was tested that interleukin-8 (IL-8), which is a cytokine that is chemotactic for lymphocytes and neutrophils, is also angiogenic. Human recombinant IL-8 was potently angiogenic when implanted in the rat cornea and induced proliferation and chemotaxis of human umbilical vein endothelial cells. Angiogenic activity present in the conditioned media of inflamed human rheumatoid synovial tissue macrophages or lipopolysaccharide-stimulated blood monocytes was equally blocked by antibodies to either IL-8 or tumor necrosis factor-alpha. An IL-8 antisense oligonucleotide specifically blocked the production of monocyte-induced angiogenic activity. These data suggest a function for macrophage-derived IL-8 in angiogenesis-dependent disorders such as rheumatoid arthritis, tumor growth, and wound repair.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koch, A E -- Polverini, P J -- Kunkel, S L -- Harlow, L A -- DiPietro, L A -- Elner, V M -- Elner, S G -- Strieter, R M -- AR30692/AR/NIAMS NIH HHS/ -- AR41492/AR/NIAMS NIH HHS/ -- HL39926/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1992 Dec 11;258(5089):1798-801.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Northwestern University Medical School, Chicago, IL 60611.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1281554" target="_blank"〉PubMed〈/a〉

    Peripheral clonal elimination of functional T cells (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-12-21
    Description: A major mechanism for generating tolerance in developing T cells is the intrathymic clonal deletion of T cells that have receptors for those self antigens that are presented on hematopoietic cells. The mechanisms of tolerance induction to antigens not expressed in the thymus remain unclear. Tolerance to self antigens can be generated extrathymically through the induction of clonal nonresponsiveness in T cells with self-reactive receptors. A second mechanism of extrathymic tolerance was identified: clonal elimination of mature T cells with self-reactive receptors that had previously displayed functional reactivity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jones, L A -- Chin, L T -- Longo, D L -- Kruisbeek, A M -- New York, N.Y. -- Science. 1990 Dec 21;250(4988):1726-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biological Response Modifiers Program, National Cancer Institute, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2125368" target="_blank"〉PubMed〈/a〉

    Association of intestinal peptide transport with a protein related to the cadherin superfamily (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-04-15
    Description: The first step in oral absorption of many medically important peptide-based drugs is mediated by an intestinal proton-dependent peptide transporter. This transporter facilitates the oral absorption of beta-lactam antibiotics and angiotensin-converting enzyme inhibitors from the intestine into enterocytes lining the luminal wall. A monoclonal antibody that blocked uptake of cephalexin was used to identify and clone a gene that encodes an approximately 92-kilodalton membrane protein that was associated with the acquisition of peptide transport activity by transport-deficient cells. The amino acid sequence deduced from the complementary DNA sequence of the cloned gene indicated that this transport-associated protein shares several conserved structural elements with the cadherin superfamily of calcium-dependent, cell-cell adhesion proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dantzig, A H -- Hoskins, J A -- Tabas, L B -- Bright, S -- Shepard, R L -- Jenkins, I L -- Duckworth, D C -- Sportsman, J R -- Mackensen, D -- Rosteck, P R Jr -- New York, N.Y. -- Science. 1994 Apr 15;264(5157):430-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lilly Research Laboratories, Eli Lilly and Company, Indianapolis, IN 46285.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8153632" target="_blank"〉PubMed〈/a〉

    Lack of acidification in Mycobacterium phagosomes produced by exclusion of the vesicular proton-ATPase (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-02-04
    Description: The success of Mycobacterium species as pathogens depends on their ability to maintain an infection inside the phagocytic vacuole of the macrophage. Although the bacteria are reported to modulate maturation of their intracellular vacuoles, the nature of such modifications is unknown. In this study, vacuoles formed around Mycobacterium avium failed to acidify below pH 6.3 to 6.5. Immunoelectron microscopy of infected macrophages and immunoblotting of isolated phagosomes showed that Mycobacterium vacuoles acquire the lysosomal membrane protein LAMP-1, but not the vesicular proton-adenosine triphosphatase (ATPase) responsible for phagosomal acidification. This suggests either a selective inhibition of fusion with proton-ATPase-containing vesicles or a rapid removal of the complex from Mycobacterium phagosomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sturgill-Koszycki, S -- Schlesinger, P H -- Chakraborty, P -- Haddix, P L -- Collins, H L -- Fok, A K -- Allen, R D -- Gluck, S L -- Heuser, J -- Russell, D G -- AI26889/AI/NIAID NIH HHS/ -- AI34207/AI/NIAID NIH HHS/ -- AR42370/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Feb 4;263(5147):678-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Microbiology, Washington University Medical Center, St. Louis, MO 63110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8303277" target="_blank"〉PubMed〈/a〉

    The prevention of thymic lymphomas in transgenic mice by human O6-alkylguanine-DNA alkyltransferase (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-01-08
    Description: Nitrosoureas form O6-alkylguanine-DNA adducts that are converted to G to A transitions, the mutation found in the activated ras oncogenes of nitrosourea-induced mouse lymphomas and rat mammary tumors. These adducts are removed by the DNA repair protein O6-alkylguanine-DNA alkyltransferase. Transgenic mice that express the human homolog of this protein in the thymus were found to be protected from developing thymic lymphomas after exposure to N-methyl-N-nitrosourea. Thus, transgenic expression of a single human DNA repair gene is sufficient to block chemical carcinogenesis. The transduction of DNA repair genes in vivo may unravel mechanisms of carcinogenesis and provide therapeutic protection from known carcinogens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dumenco, L L -- Allay, E -- Norton, K -- Gerson, S L -- P01CA51183/CA/NCI NIH HHS/ -- P30CA43703/CA/NCI NIH HHS/ -- R01ES06288/ES/NIEHS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1993 Jan 8;259(5092):219-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University Hospitals of Cleveland, OH.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8421782" target="_blank"〉PubMed〈/a〉

    Presentation of exogenous antigen with class I major histocompatibility complex molecules (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-08-24
    Description: Soluble antigens (Ags) in the extracellular fluids are excluded from the class I major histocompatibility complex (MHC)-restricted pathway of Ag presentation in most cells. However, an exogenous Ag can be internalized, processed, and presented in association with class I MHC molecules on specialized Ag-presenting cells (APCs). These APCs express class II molecules and can simultaneously present exogenous Ags to both class I and class II MHC-restricted T cells. These APCs may be important participants in the regulation of host immune responses. This APC activity may explain several phenomena of cytotoxic T lymphocyte (CTL) priming in vivo and might be exploited for eliciting CTL responses to protein vaccines.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rock, K L -- Gamble, S -- Rothstein, L -- AI-20248/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1990 Aug 24;249(4971):918-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Harvard Medical School, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2392683" target="_blank"〉PubMed〈/a〉

    Function of the homeodomain protein GHF1 in pituitary cell proliferation (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-07-12
    Description: Mutations that cause pituitary dwarfism in the mouse reside in the gene encoding the transcription factor growth hormone factor 1 (GHF1 or pit1). These dwarf mice (dw and dwJ) are deficient in growth hormone (GH) and prolactin (PRL) synthesis and exhibit pituitary hypoplasia, suggesting a stem cell defect. With antisense oligonucleotide technology, a cell culture model of this genetic defect was developed. Specific inhibition of GHF1 synthesis by complementary oligonucleotides led to a marked decrease in GH and PRL expression and to a marked decrease in proliferation of somatotrophic cell lines. These results provide direct evidence that the homeodomain protein GHF1 is required not only for the establishment and maintenance of the differentiated phenotype but for cell proliferation as well.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Castrillo, J L -- Theill, L E -- Karin, M -- DK38527/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1991 Jul 12;253(5016):197-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, School of Medicine, University of California, San Diego, La Jolla 92093.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1677216" target="_blank"〉PubMed〈/a〉
