    Molecular evidence for the early evolution of photosynthesis (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-09-08
    Description: The origin and evolution of photosynthesis have long remained enigmatic due to a lack of sequence information of photosynthesis genes across the entire photosynthetic domain. To probe early evolutionary history of photosynthesis, we obtained new sequence information of a number of photosynthesis genes from the green sulfur bacterium Chlorobium tepidum and the green nonsulfur bacterium Chloroflexus aurantiacus. A total of 31 open reading frames that encode enzymes involved in bacteriochlorophyll/porphyrin biosynthesis, carotenoid biosynthesis, and photosynthetic electron transfer were identified in about 100 kilobase pairs of genomic sequence. Phylogenetic analyses of multiple magnesium-tetrapyrrole biosynthesis genes using a combination of distance, maximum parsimony, and maximum likelihood methods indicate that heliobacteria are closest to the last common ancestor of all oxygenic photosynthetic lineages and that green sulfur bacteria and green nonsulfur bacteria are each other's closest relatives. Parsimony and distance analyses further identify purple bacteria as the earliest emerging photosynthetic lineage. These results challenge previous conclusions based on 16S ribosomal RNA and Hsp60/Hsp70 analyses that green nonsulfur bacteria or heliobacteria are the earliest phototrophs. The overall consensus of our phylogenetic analysis, that bacteriochlorophyll biosynthesis evolved before chlorophyll biosynthesis, also argues against the long-held Granick hypothesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xiong, J -- Fischer, W M -- Inoue, K -- Nakahara, M -- Bauer, C E -- GM53940/GM/NIGMS NIH HHS/ -- R01 GM053940/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2000 Sep 8;289(5485):1724-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Indiana University, Bloomington, IN 47405, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10976061" target="_blank"〉PubMed〈/a〉

    Impairment of mycobacterial immunity in human interleukin-12 receptor deficiency (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-06-20
    Description: In humans, interferon gamma (IFN-gamma) receptor deficiency leads to a predisposition to mycobacterial infections and impairs the formation of mature granulomas. Interleukin-12 (IL-12) receptor deficiency was found in otherwise healthy individuals with mycobacterial infections. Mature granulomas were seen, surrounded by T cells and centered with epithelioid and multinucleated giant cells, yet reduced IFN-gamma concentrations were found to be secreted by activated natural killer and T cells. Thus, IL-12-dependent IFN-gamma secretion in humans seems essential in the control of mycobacterial infections, despite the formation of mature granulomas due to IL-12-independent IFN-gamma secretion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Altare, F -- Durandy, A -- Lammas, D -- Emile, J F -- Lamhamedi, S -- Le Deist, F -- Drysdale, P -- Jouanguy, E -- Doffinger, R -- Bernaudin, F -- Jeppsson, O -- Gollob, J A -- Meinl, E -- Segal, A W -- Fischer, A -- Kumararatne, D -- Casanova, J L -- New York, N.Y. -- Science. 1998 May 29;280(5368):1432-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INSERM U429, Hopital Necker-Enfants Malades, Paris 75015, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9603732" target="_blank"〉PubMed〈/a〉

    Gene therapy of human severe combined immunodeficiency (SCID)-X1 disease (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-04-28
    Description: Severe combined immunodeficiency-X1 (SCID-X1) is an X-linked inherited disorder characterized by an early block in T and natural killer (NK) lymphocyte differentiation. This block is caused by mutations of the gene encoding the gammac cytokine receptor subunit of interleukin-2, -4, -7, -9, and -15 receptors, which participates in the delivery of growth, survival, and differentiation signals to early lymphoid progenitors. After preclinical studies, a gene therapy trial for SCID-X1 was initiated, based on the use of complementary DNA containing a defective gammac Moloney retrovirus-derived vector and ex vivo infection of CD34+ cells. After a 10-month follow-up period, gammac transgene-expressing T and NK cells were detected in two patients. T, B, and NK cell counts and function, including antigen-specific responses, were comparable to those of age-matched controls. Thus, gene therapy was able to provide full correction of disease phenotype and, hence, clinical benefit.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cavazzana-Calvo, M -- Hacein-Bey, S -- de Saint Basile, G -- Gross, F -- Yvon, E -- Nusbaum, P -- Selz, F -- Hue, C -- Certain, S -- Casanova, J L -- Bousso, P -- Deist, F L -- Fischer, A -- New York, N.Y. -- Science. 2000 Apr 28;288(5466):669-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INSERM Unit 429, Gene Therapy Laboratory, Cell Therapy Laboratory, Unite d'Immunologie et d'Hematologie Pediatriques, Hopital Necker, 75743 Paris Cedex 15, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10784449" target="_blank"〉PubMed〈/a〉

    Localization of a short-term memory in Drosophila (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-04-28
    Description: Memories are thought to be due to lasting synaptic modifications in the brain. The search for memory traces has relied predominantly on determining regions that are necessary for the process. However, a more informative approach is to define the smallest sufficient set of brain structures. The rutabaga adenylyl cyclase, an enzyme that is ubiquitously expressed in the Drosophila brain and that mediates synaptic plasticity, is needed exclusively in the Kenyon cells of the mushroom bodies for a component of olfactory short-term memory. This demonstrates that synaptic plasticity in a small brain region can be sufficient for memory formation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zars, T -- Fischer, M -- Schulz, R -- Heisenberg, M -- New York, N.Y. -- Science. 2000 Apr 28;288(5466):672-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Theodor Boveri Institut fur Biowissenschaften, Lehrstuhl fur Genetik, (Biozentrum) Am Hubland, D97074, Wurzburg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10784450" target="_blank"〉PubMed〈/a〉

    Sequence-specific and phosphorylation-dependent proline isomerization: a potential mitotic regulatory mechanism (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-01-07
    Description: Pin1 is an essential and conserved mitotic peptidyl-prolyl isomerase (PPIase) that is distinct from members of two other families of conventional PPIases, cyclophilins and FKBPs (FK-506 binding proteins). In response to their phosphorylation during mitosis, Pin1 binds and regulates members of a highly conserved set of proteins that overlaps with antigens recognized by the mitosis-specific monoclonal antibody MPM-2. Pin1 is here shown to be a phosphorylation-dependent PPIase that specifically recognizes the phosphoserine-proline or phosphothreonine-proline bonds present in mitotic phosphoproteins. Both Pin1 and MPM-2 selected similar phosphorylated serine-proline-containing peptides, providing the basis for the specific interaction between Pin1 and MPM-2 antigens. Pin1 preferentially isomerized proline residues preceded by phosphorylated serine or threonine with up to 1300-fold selectivity compared with unphosphorylated peptides. Pin1 may thus regulate mitotic progression by catalyzing sequence-specific and phosphorylation-dependent proline isomerization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yaffe, M B -- Schutkowski, M -- Shen, M -- Zhou, X Z -- Stukenberg, P T -- Rahfeld, J U -- Xu, J -- Kuang, J -- Kirschner, M W -- Fischer, G -- Cantley, L C -- Lu, K P -- GM56203/GM/NIGMS NIH HHS/ -- GM56230/GM/NIGMS NIH HHS/ -- R01 GM056203/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Dec 12;278(5345):1957-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine Beth Israel Deaconess Medical Center, Boston, MA 02215, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9395400" target="_blank"〉PubMed〈/a〉

    Cleavage of the BMP-4 antagonist chordin by zebrafish tolloid (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-01-07
    Description: Dorsoventral patterning of vertebrate and Drosophila embryos requires bone morphogenetic proteins (BMPs) and antagonists of BMP activity. The Drosophila gene tolloid encodes a metalloprotease similar to BMP-1 that interacts genetically with decapentaplegic, the Drosophila homolog of vertebrate BMP-2/4. Zebrafish embryos overexpressing a zebrafish homolog of tolloid were shown to resemble loss-of-function mutations in chordino, the zebrafish homolog of the Xenopus BMP-4 antagonist Chordin. Furthermore, Chordin was degraded by COS cells expressing Tolloid. These data suggest that Tolloid antagonizes Chordin activity by proteolytically cleaving Chordin. A conserved function for zebrafish and Drosophila Tolloid during embryogenesis is proposed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blader, P -- Rastegar, S -- Fischer, N -- Strahle, U -- New York, N.Y. -- Science. 1997 Dec 12;278(5345):1937-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Genetique et de Biologie Moleculaire et Cellulaire (IGBMC), CNRS/INSERM/ULP, BP 163, 67404 Illkirch Cedex, C.U. de Strasbourg, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9395394" target="_blank"〉PubMed〈/a〉

    Word learning in a domestic dog: evidence for "fast mapping" (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-06-12
    Description: During speech acquisition, children form quick and rough hypotheses about the meaning of a new word after only a single exposure-a process dubbed "fast mapping." Here we provide evidence that a border collie, Rico, is able to fast map. Rico knew the labels of over 200 different items. He inferred the names of novel items by exclusion learning and correctly retrieved those items right away as well as 4 weeks after the initial exposure. Fast mapping thus appears to be mediated by general learning and memory mechanisms also found in other animals and not by a language acquisition device that is special to humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaminski, Juliane -- Call, Josep -- Fischer, Julia -- New York, N.Y. -- Science. 2004 Jun 11;304(5677):1682-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Developmental and Comparative Psychology, Max-Planck Institute for Evolutionary Anthropology, Deutscher Platz 6, 04103 Leipzig, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15192233" target="_blank"〉PubMed〈/a〉

    Helicobacter pylori vacuolating cytotoxin inhibits T lymphocyte activation (2003)

    Publication Date: 2003-08-23
    Description: Helicobacter pylori (Hp) vacuolating cytotoxin VacA induces cellular vacuolation in epithelial cells. We found that VacA could efficiently block proliferation of T cells by inducing a G1/S cell cycle arrest. It interfered with the T cell receptor/interleukin-2 (IL-2) signaling pathway at the level of the Ca2+-calmodulin-dependent phosphatase calcineurin. Nuclear translocation of nuclear factor of activated T cells (NFAT), a transcription factor acting as a global regulator of immune response genes, was abrogated, resulting in down-regulation of IL-2 transcription. VacA partially mimicked the activity of the immunosuppressive drug FK506 by possibly inducing a local immune suppression, explaining the extraordinary chronicity of Hp infections.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gebert, Bettina -- Fischer, Wolfgang -- Weiss, Evelyn -- Hoffmann, Reinhard -- Haas, Rainer -- New York, N.Y. -- Science. 2003 Aug 22;301(5636):1099-102.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max von Pettenkofer-Institut fur Hygiene und Medizinische Mikrobiologie, LMU Munchen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12934009" target="_blank"〉PubMed〈/a〉

    Axonal neuregulin-1 regulates myelin sheath thickness (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-03-27
    Description: In the nervous system of vertebrates, myelination is essential for rapid and accurate impulse conduction. Myelin thickness depends on axon fiber size. We use mutant and transgenic mouse lines to show that axonal Neuregulin-1 (Nrg1) signals information about axon size to Schwann cells. Reduced Nrg1 expression causes hypomyelination and reduced nerve conduction velocity. Neuronal overexpression of Nrg1 induces hypermyelination and demonstrates that Nrg1 type III is the responsible isoform. We suggest a model by which myelin-forming Schwann cells integrate axonal Nrg1 signals as a biochemical measure of axon size.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Michailov, Galin V -- Sereda, Michael W -- Brinkmann, Bastian G -- Fischer, Tobias M -- Haug, Bernhard -- Birchmeier, Carmen -- Role, Lorna -- Lai, Cary -- Schwab, Markus H -- Nave, Klaus-Armin -- New York, N.Y. -- Science. 2004 Apr 30;304(5671):700-3.

    Dependence of germinal center B cells on expression of CD21/CD35 for survival (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-05-09
    Description: Affinity-driven selection of B lymphocytes within germinal centers is critical for the development of high-affinity memory cells and host protection. To investigate the role of the CD21/CD35 coreceptor in B cell competition for follicular retention and survival within the germinal center, either Cr2+ or Cr2null lysozyme-specific transgenic B cells were adoptively transferred into normal mice immunized with duck (DEL) or turkey (TEL) lysozyme, which bind with different affinities. In mice injected with high-affinity turkey lysozyme, Cr2null B cells responded by follicular retention; however, they could not survive within germinal centers. This suggests that CD21 provides a signal independent of antigen that is required for survival of B cells in the germinal center.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fischer, M B -- Goerg, S -- Shen, L -- Prodeus, A P -- Goodnow, C C -- Kelsoe, G -- Carroll, M C -- New York, N.Y. -- Science. 1998 Apr 24;280(5363):582-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9554848" target="_blank"〉PubMed〈/a〉
