    Treatment of autoimmune neuroinflammation with a synthetic tryptophan metabolite (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-11-08
    Description: Local catabolism of the amino acid tryptophan (Trp) by indoleamine 2,3-dioxygenase (IDO) is considered an important mechanism of regulating T cell immunity. We show that IDO transcription was increased when myelin-specific T cells were stimulated with tolerogenic altered self-peptides. Catabolites of Trp suppressed proliferation of myelin-specific T cells and inhibited production of proinflammatory T helper-1 (T(H)1) cytokines. N-(3,4,-Dimethoxycinnamoyl) anthranilic acid (3,4-DAA), an orally active synthetic derivative of the Trp metabolite anthranilic acid, reversed paralysis in mice with experimental autoimmune encephalomyelitis, a model of multiple sclerosis (MS). Trp catabolites and their derivatives offer a new strategy for treating T(H)1-mediated autoimmune diseases such as MS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Platten, Michael -- Ho, Peggy P -- Youssef, Sawsan -- Fontoura, Paulo -- Garren, Hideki -- Hur, Eun Mi -- Gupta, Rohit -- Lee, Lowen Y -- Kidd, Brian A -- Robinson, William H -- Sobel, Raymond A -- Selley, Michael L -- Steinman, Lawrence -- New York, N.Y. -- Science. 2005 Nov 4;310(5749):850-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology and Neurological Sciences, Beckman Center for Molecular Medicine, Stanford University, Stanford, CA 94305, USA. michael.platten@uni-tuebingen.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16272121" target="_blank"〉PubMed〈/a〉

    An aneuploid mouse strain carrying human chromosome 21 with Down syndrome phenotypes (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-09-24
    Description: Aneuploidies are common chromosomal defects that result in growth and developmental deficits and high levels of lethality in humans. To gain insight into the biology of aneuploidies, we manipulated mouse embryonic stem cells and generated a trans-species aneuploid mouse line that stably transmits a freely segregating, almost complete human chromosome 21 (Hsa21). This "transchromosomic" mouse line, Tc1, is a model of trisomy 21, which manifests as Down syndrome (DS) in humans, and has phenotypic alterations in behavior, synaptic plasticity, cerebellar neuronal number, heart development, and mandible size that relate to human DS. Transchromosomic mouse lines such as Tc1 may represent useful genetic tools for dissecting other human aneuploidies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1378183/" 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/PMC1378183/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Doherty, Aideen -- Ruf, Sandra -- Mulligan, Claire -- Hildreth, Victoria -- Errington, Mick L -- Cooke, Sam -- Sesay, Abdul -- Modino, Sonie -- Vanes, Lesley -- Hernandez, Diana -- Linehan, Jacqueline M -- Sharpe, Paul T -- Brandner, Sebastian -- Bliss, Timothy V P -- Henderson, Deborah J -- Nizetic, Dean -- Tybulewicz, Victor L J -- Fisher, Elizabeth M C -- 076700/Wellcome Trust/United Kingdom -- MC_U117512674/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2005 Sep 23;309(5743):2033-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurodegenerative Disease, Institute of Neurology, Queen Square, London WC1N 3BG, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16179473" target="_blank"〉PubMed〈/a〉

    Bacterial injectisomes: needle length does matter (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-02-26
    Description: Many pathogenic bacteria use a type III secretion nanomachine (an injectisome) to deliver virulence proteins into the cytosol of their eukaryotic host cells. Most injectisomes possess a stiff needlelike structure of a genetically defined length. We found that a minimal needle length was required for efficient functioning of the Yersinia enterocolitica injectisome. This minimal needle length correlated with the length of the major adhesin at the bacterial surface. The needle may be required for triggering type III secretion, and its length may have evolved to match specific structures at the bacterial and host cell surfaces.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mota, Luis Jaime -- Journet, Laure -- Sorg, Isabel -- Agrain, Celine -- Cornelis, Guy R -- New York, N.Y. -- Science. 2005 Feb 25;307(5713):1278.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biozentrum, Universitat Basel, 4056 Basel, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15731447" target="_blank"〉PubMed〈/a〉

    A mutation in the TRPC6 cation channel causes familial focal segmental glomerulosclerosis (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-05-10
    Description: Focal and segmental glomerulosclerosis (FSGS) is a kidney disorder of unknown etiology, and up to 20% of patients on dialysis have been diagnosed with it. Here we show that a large family with hereditary FSGS carries a missense mutation in the TRPC6 gene on chromosome 11q, encoding the ion-channel protein transient receptor potential cation channel 6 (TRPC6). The proline-to-glutamine substitution at position 112, which occurs in a highly conserved region of the protein, enhances TRPC6-mediated calcium signals in response to agonists such as angiotensin II and appears to alter the intracellular distribution of TRPC6 protein. Previous work has emphasized the importance of cytoskeletal and structural proteins in proteinuric kidney diseases. Our findings suggest an alternative mechanism for the pathogenesis of glomerular disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Winn, Michelle P -- Conlon, Peter J -- Lynn, Kelvin L -- Farrington, Merry Kay -- Creazzo, Tony -- Hawkins, April F -- Daskalakis, Nikki -- Kwan, Shu Ying -- Ebersviller, Seth -- Burchette, James L -- Pericak-Vance, Margaret A -- Howell, David N -- Vance, Jeffery M -- Rosenberg, Paul B -- R01 DK074748/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2005 Jun 17;308(5729):1801-4.

    Recognition of host immune activation by Pseudomonas aeruginosa (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-07-30
    Description: It is generally reasoned that lethal infections caused by opportunistic pathogens develop permissively by invading a host that is both physiologically stressed and immunologically compromised. However, an alternative hypothesis might be that opportunistic pathogens actively sense alterations in host immune function and respond by enhancing their virulence phenotype. We demonstrate that interferon-gamma binds to an outer membrane protein in Pseudomonas aeruginosa, OprF, resulting in the expression of a quorum-sensing dependent virulence determinant, the PA-I lectin. These observations provide details of the mechanisms by which prokaryotic organisms are directly signaled by immune activation in their eukaryotic host.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Licheng -- Estrada, Oscar -- Zaborina, Olga -- Bains, Manjeet -- Shen, Le -- Kohler, Jonathan E -- Patel, Nachiket -- Musch, Mark W -- Chang, Eugene B -- Fu, Yang-Xin -- Jacobs, Michael A -- Nishimura, Michael I -- Hancock, Robert E W -- Turner, Jerrold R -- Alverdy, John C -- 2-RO1 GM062344-05/GM/NIGMS NIH HHS/ -- DK-38510/DK/NIDDK NIH HHS/ -- DK-47722/DK/NIDDK NIH HHS/ -- R01DK61931/DK/NIDDK NIH HHS/ -- R01DK68271/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2005 Jul 29;309(5735):774-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Surgery, University of Chicago, Pritzker School of Medicine, Chicago, IL 60637, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16051797" target="_blank"〉PubMed〈/a〉

    Extensive diversity of Ig-superfamily proteins in the immune system of insects (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-08-20
    Description: The extensive somatic diversification of immune receptors is a hallmark of higher vertebrates. However, whether molecular diversity contributes to immune protection in invertebrates is unknown. We present evidence that Drosophila immune-competent cells have the potential to express more than 18,000 isoforms of the immunoglobulin (Ig)-superfamily receptor Down syndrome cell adhesion molecule (Dscam). Secreted protein isoforms of Dscam were detected in the hemolymph, and hemocyte-specific loss of Dscam impaired the efficiency of phagocytic uptake of bacteria, possibly due to reduced bacterial binding. Importantly, the molecular diversity of Dscam transcripts generated through a mechanism of alternative splicing is highly conserved across major insect orders, suggesting an unsuspected molecular complexity of the innate immune system of insects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Watson, Fiona L -- Puttmann-Holgado, Roland -- Thomas, Franziska -- Lamar, David L -- Hughes, Michael -- Kondo, Masahiro -- Rebel, Vivienne I -- Schmucker, Dietmar -- 1RO1-NS46747-01/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2005 Sep 16;309(5742):1874-8.

    Requirement for caspase-8 in NF-kappaB activation by antigen receptor (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-03-05
    Description: Caspase-8, a proapoptotic protease, has an essential role in lymphocyte activation and protective immunity. We show that caspase-8 deficiency (CED) in humans and mice specifically abolishes activation of the transcription factor nuclear factor kappaB (NF-kappaB) after stimulation through antigen receptors, Fc receptors, or Toll-like receptor 4 in T, B, and natural killer cells. Caspase-8 also causes the alphabeta complex of the inhibitor of NF-kappaB kinase (IKK) to associate with the upstream Bcl10-MALT1 (mucosa-associated lymphatic tissue) adapter complex. Recruitment of the IKKalpha, beta complex, its activation, and the nuclear translocation of NF-kappaB require enzyme activity of full-length caspase-8. These findings thus explain the paradoxical association of defective apoptosis and combined immunodeficiency in human CED.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Su, Helen -- Bidere, Nicolas -- Zheng, Lixin -- Cubre, Alan -- Sakai, Keiko -- Dale, Janet -- Salmena, Leonardo -- Hakem, Razqallah -- Straus, Stephen -- Lenardo, Michael -- New York, N.Y. -- Science. 2005 Mar 4;307(5714):1465-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immunology, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15746428" target="_blank"〉PubMed〈/a〉

    Transmission of equine influenza virus to dogs (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-09-28
    Description: Molecular and antigenic analyses of three influenza viruses isolated from outbreaks of severe respiratory disease in racing greyhounds revealed that they are closely related to H3N8 equine influenza virus. Phylogenetic analysis indicated that the canine influenza virus genomes form a monophyletic group, consistent with a single interspecies virus transfer. Molecular changes in the hemagglutinin suggested adaptive evolution in the new host. The etiologic role of this virus in respiratory disease was supported by the temporal association of rising antibody titers with disease and by experimental inoculation studies. The geographic expansion of the infection and its persistence for several years indicate efficient transmission of canine influenza virus among greyhounds. Evidence of infection in pet dogs suggests that this infection may also become enzootic in this population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crawford, P C -- Dubovi, Edward J -- Castleman, William L -- Stephenson, Iain -- Gibbs, E P J -- Chen, Limei -- Smith, Catherine -- Hill, Richard C -- Ferro, Pamela -- Pompey, Justine -- Bright, Rick A -- Medina, Marie-Jo -- Johnson, Calvin M -- Olsen, Christopher W -- Cox, Nancy J -- Klimov, Alexander I -- Katz, Jacqueline M -- Donis, Ruben O -- New York, N.Y. -- Science. 2005 Oct 21;310(5747):482-5.

    The kinase domain of titin controls muscle gene expression and protein turnover (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-04-02
    Description: The giant sarcomeric protein titin contains a protein kinase domain (TK) ideally positioned to sense mechanical load. We identified a signaling complex where TK interacts with the zinc-finger protein nbr1 through a mechanically inducible conformation. Nbr1 targets the ubiquitin-associated p62/SQSTM1 to sarcomeres, and p62 in turn interacts with MuRF2, a muscle-specific RING-B-box E3 ligase and ligand of the transactivation domain of the serum response transcription factor (SRF). Nuclear translocation of MuRF2 was induced by mechanical inactivity and caused reduction of nuclear SRF and repression of transcription. A human mutation in the titin protein kinase domain causes hereditary muscle disease by disrupting this pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lange, Stephan -- Xiang, Fengqing -- Yakovenko, Andrey -- Vihola, Anna -- Hackman, Peter -- Rostkova, Elena -- Kristensen, Jakob -- Brandmeier, Birgit -- Franzen, Gereon -- Hedberg, Birgitta -- Gunnarsson, Lars Gunnar -- Hughes, Simon M -- Marchand, Sylvie -- Sejersen, Thomas -- Richard, Isabelle -- Edstrom, Lars -- Ehler, Elisabeth -- Udd, Bjarne -- Gautel, Mathias -- G0200496(63216)/Medical Research Council/United Kingdom -- G0300213/Medical Research Council/United Kingdom -- PG/03/049/15364/British Heart Foundation/United Kingdom -- New York, N.Y. -- Science. 2005 Jun 10;308(5728):1599-603.

    Topography of the 81/P Wild 2 Nucleus Derived from Stardust Stereoimages (2005)
    In:  CASI
    Details
    Publication Date: 2017-10-02
    Description: On 2 January, 2004, the Stardust spacecraft flew by the nucleus of comet 81P/Wild 2 with a closest approach distance of approx. 240 km. During the encounter, the Stardust Optical Navigation Camera (ONC) obtained 72 images of the nucleus with exposure times alternating between 10 ms (near-optimal for most of the nucleus surface) and 100 ms (used for navigation, and revealing additional details in the coma and dark portions of the surface. Phase angles varied from 72 deg. to near zero to 103 deg. during the encounter, allowing the entire sunlit portion of the surface to be imaged. As many as 20 of the images near closest approach are of sufficiently high resolution to be used in mapping the nucleus surface; of these, two pairs of short-exposure images were used to create the nucleus shape model and derived products reported here. The best image resolution obtained was approx. 14 m/pixel, resulting in approx. 300 pixels across the nucleus. The Stardust Wild 2 dataset is therefore markedly superior from a stereomapping perspective to the Deep Space 1 MICAS images of comet Borrelly. The key subset of the latter (3 images) covered only about a quarter of the surface at phase angles approx. 50 - 60 and less than 50 x 160 pixels across the nucleus, yet it sufficed for groups at the USGS and DLR to produce digital elevation models (DEMs) and study the morphology and photometry of the nucleus in detail.
