    Structure of the cell wall anchor of surface proteins in Staphylococcus aureus (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-04-07
    Description: Many surface proteins are anchored to the cell wall of Gram-positive bacteria and are involved in the pathogenesis of these organisms. A hybrid molecule was designed that, when expressed in Staphylococcus aureus, was anchored to the cell wall and could be released by controlled enzymatic digestion. By a combination of molecular biology and mass spectrometry techniques, the structure of the cell wall anchor of surface proteins in S. aureus was revealed. After cleavage of surface proteins between threonine and glycine of the conserved LPXTG motif, the carboxyl of threonine is amide-linked to the free amino group of the pentaglycine crossbridge in the staphylococcal cell wall.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schneewind, O -- Fowler, A -- Faull, K F -- AI 33985/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1995 Apr 7;268(5207):103-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, University of California School of Medicine, Los Angeles 90024, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7701329" target="_blank"〉PubMed〈/a〉

    Human neuroblasts migrate to the olfactory bulb via a lateral ventricular extension (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-02-17
    Description: The rostral migratory stream (RMS) is the main pathway by which newly born subventricular zone cells reach the olfactory bulb (OB) in rodents. However, the RMS in the adult human brain has been elusive. We demonstrate the presence of a human RMS, which is unexpectedly organized around a lateral ventricular extension reaching the OB, and illustrate the neuroblasts in it. The RMS ensheathing the lateral olfactory ventricular extension, as seen by magnetic resonance imaging, cell-specific markers, and electron microscopy, contains progenitor cells with migratory characteristics and cells that incorporate 5-bromo-2'-deoxyuridine and become mature neurons in the OB.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Curtis, Maurice A -- Kam, Monica -- Nannmark, Ulf -- Anderson, Michelle F -- Axell, Mathilda Zetterstrom -- Wikkelso, Carsten -- Holtas, Stig -- van Roon-Mom, Willeke M C -- Bjork-Eriksson, Thomas -- Nordborg, Claes -- Frisen, Jonas -- Dragunow, Michael -- Faull, Richard L M -- Eriksson, Peter S -- New York, N.Y. -- Science. 2007 Mar 2;315(5816):1243-9.
