    Description: The mechanism by which multispanning helix-bundle membrane proteins are inserted into their target membrane remains unclear. In both prokaryotic and eukaryotic cells, membrane proteins are inserted cotranslationally into the lipid bilayer. Positively charged residues flanking the transmembrane helices are important topological determinants, but it is not known whether they act strictly locally, affecting only the nearest transmembrane helices, or can act globally, affecting the topology of the entire protein. Here we found that the topology of an Escherichia coli inner membrane protein with four or five transmembrane helices could be controlled by a single positively charged residue placed in different locations throughout the protein, including the very C terminus. This observation points to an unanticipated plasticity in membrane protein insertion mechanisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seppala, Susanna -- Slusky, Joanna S -- Lloris-Garcera, Pilar -- Rapp, Mikaela -- von Heijne, Gunnar -- 232648/European Research Council/International -- New York, N.Y. -- Science. 2010 Jun 25;328(5986):1698-700. doi: 10.1126/science.1188950.

    Description: CKAMP44, identified here by a proteomic approach, is a brain-specific type I transmembrane protein that associates with AMPA receptors in synaptic spines. CKAMP44 expressed in Xenopus oocytes reduced GluA1- and A2-mediated steady-state currents, but did not affect kainate- or N-methyl-D-aspartate (NMDA) receptor-mediated currents. Mouse hippocampal CA1 pyramidal neurons expressed CKAMP44 at low abundance, and overexpression of CKAMP44 led to stronger and faster AMPA receptor desensitization, slower recovery from desensitization, and a reduction in the paired-pulse ratio of AMPA currents. By contrast, dentate gyrus granule cells exhibited strong CKAMP44 expression, and CKAMP44 knockout increased the paired-pulse ratio of AMPA currents in lateral and medial perforant path-granule cell synapses. CKAMP44 thus modulates short-term plasticity at specific excitatory synapses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉von Engelhardt, Jakob -- Mack, Volker -- Sprengel, Rolf -- Kavenstock, Netta -- Li, Ka Wan -- Stern-Bach, Yael -- Smit, August B -- Seeburg, Peter H -- Monyer, Hannah -- New York, N.Y. -- Science. 2010 Mar 19;327(5972):1518-22. doi: 10.1126/science.1184178.

    Description: The large-scale assembly of nanowires with controlled orientation on surfaces remains one challenge preventing their integration into practical devices. We report the vapor-liquid-solid growth of aligned, millimeter-long, horizontal GaN nanowires with controlled crystallographic orientations on different planes of sapphire. The growth directions, crystallographic orientation, and faceting of the nanowires vary with each surface orientation, as determined by their epitaxial relationship with the substrate, as well as by a graphoepitaxial effect that guides their growth along surface steps and grooves. Despite their interaction with the surface, these horizontally grown nanowires display few structural defects, exhibiting optical and electronic properties comparable to those of vertically grown nanowires. This paves the way to highly controlled nanowire structures with potential applications not available by other means.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsivion, David -- Schvartzman, Mark -- Popovitz-Biro, Ronit -- von Huth, Palle -- Joselevich, Ernesto -- New York, N.Y. -- Science. 2011 Aug 19;333(6045):1003-7. doi: 10.1126/science.1208455.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Materials and Interfaces, Weizmann Institute of Science, Rehovot 76100, Israel.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21852496" target="_blank"〉PubMed〈/a〉

    Description: Epidemiological studies of the naturally transformable bacterial pathogen Streptococcus pneumoniae have previously been confounded by high rates of recombination. Sequencing 240 isolates of the PMEN1 (Spain(23F)-1) multidrug-resistant lineage enabled base substitutions to be distinguished from polymorphisms arising through horizontal sequence transfer. More than 700 recombinations were detected, with genes encoding major antigens frequently affected. Among these were 10 capsule-switching events, one of which accompanied a population shift as vaccine-escape serotype 19A isolates emerged in the USA after the introduction of the conjugate polysaccharide vaccine. The evolution of resistance to fluoroquinolones, rifampicin, and macrolides was observed to occur on multiple occasions. This study details how genomic plasticity within lineages of recombinogenic bacteria can permit adaptation to clinical interventions over remarkably short time scales.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3648787/" 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/PMC3648787/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Croucher, Nicholas J -- Harris, Simon R -- Fraser, Christophe -- Quail, Michael A -- Burton, John -- van der Linden, Mark -- McGee, Lesley -- von Gottberg, Anne -- Song, Jae Hoon -- Ko, Kwan Soo -- Pichon, Bruno -- Baker, Stephen -- Parry, Christopher M -- Lambertsen, Lotte M -- Shahinas, Dea -- Pillai, Dylan R -- Mitchell, Timothy J -- Dougan, Gordon -- Tomasz, Alexander -- Klugman, Keith P -- Parkhill, Julian -- Hanage, William P -- Bentley, Stephen D -- 076962/Wellcome Trust/United Kingdom -- 076964/Wellcome Trust/United Kingdom -- G0800596/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2011 Jan 28;331(6016):430-4. doi: 10.1126/science.1198545.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Hinxton, Cambridge CB10 1SA, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21273480" target="_blank"〉PubMed〈/a〉

    Description: Topologically nontrivial spin textures have recently been investigated for spintronic applications. Here, we report on an ultrathin magnetic film in which individual skyrmions can be written and deleted in a controlled fashion with local spin-polarized currents from a scanning tunneling microscope. An external magnetic field is used to tune the energy landscape, and the temperature is adjusted to prevent thermally activated switching between topologically distinct states. Switching rate and direction can then be controlled by the parameters used for current injection. The creation and annihilation of individual magnetic skyrmions demonstrates the potential for topological charge in future information-storage concepts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Romming, Niklas -- Hanneken, Christian -- Menzel, Matthias -- Bickel, Jessica E -- Wolter, Boris -- von Bergmann, Kirsten -- Kubetzka, Andre -- Wiesendanger, Roland -- New York, N.Y. -- Science. 2013 Aug 9;341(6146):636-9. doi: 10.1126/science.1240573.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Applied Physics, University of Hamburg, D-20355 Hamburg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23929977" target="_blank"〉PubMed〈/a〉

    Description: Wiskott-Aldrich syndrome (WAS) is an inherited immunodeficiency caused by mutations in the gene encoding WASP, a protein regulating the cytoskeleton. Hematopoietic stem/progenitor cell (HSPC) transplants can be curative, but, when matched donors are unavailable, infusion of autologous HSPCs modified ex vivo by gene therapy is an alternative approach. We used a lentiviral vector encoding functional WASP to genetically correct HSPCs from three WAS patients and reinfused the cells after a reduced-intensity conditioning regimen. All three patients showed stable engraftment of WASP-expressing cells and improvements in platelet counts, immune functions, and clinical scores. Vector integration analyses revealed highly polyclonal and multilineage haematopoiesis resulting from the gene-corrected HSPCs. Lentiviral gene therapy did not induce selection of integrations near oncogenes, and no aberrant clonal expansion was observed after 20 to 32 months. Although extended clinical observation is required to establish long-term safety, lentiviral gene therapy represents a promising treatment for WAS.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4375961/" 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/PMC4375961/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aiuti, Alessandro -- Biasco, Luca -- Scaramuzza, Samantha -- Ferrua, Francesca -- Cicalese, Maria Pia -- Baricordi, Cristina -- Dionisio, Francesca -- Calabria, Andrea -- Giannelli, Stefania -- Castiello, Maria Carmina -- Bosticardo, Marita -- Evangelio, Costanza -- Assanelli, Andrea -- Casiraghi, Miriam -- Di Nunzio, Sara -- Callegaro, Luciano -- Benati, Claudia -- Rizzardi, Paolo -- Pellin, Danilo -- Di Serio, Clelia -- Schmidt, Manfred -- Von Kalle, Christof -- Gardner, Jason -- Mehta, Nalini -- Neduva, Victor -- Dow, David J -- Galy, Anne -- Miniero, Roberto -- Finocchi, Andrea -- Metin, Ayse -- Banerjee, Pinaki P -- Orange, Jordan S -- Galimberti, Stefania -- Valsecchi, Maria Grazia -- Biffi, Alessandra -- Montini, Eugenio -- Villa, Anna -- Ciceri, Fabio -- Roncarolo, Maria Grazia -- Naldini, Luigi -- R01 AI067946/AI/NIAID NIH HHS/ -- TGT11D01/Telethon/Italy -- TGT11D02/Telethon/Italy -- New York, N.Y. -- Science. 2013 Aug 23;341(6148):1233151. doi: 10.1126/science.1233151.

    Description: Strongly interacting quantum many-body systems arise in many areas of physics, but their complexity generally precludes exact solutions to their dynamics. We explored a strongly interacting two-level system formed by the clock states in (87)Sr as a laboratory for the study of quantum many-body effects. Our collective spin measurements reveal signatures of the development of many-body correlations during the dynamical evolution. We derived a many-body Hamiltonian that describes the experimental observation of atomic spin coherence decay, density-dependent frequency shifts, severely distorted lineshapes, and correlated spin noise. These investigations open the door to further explorations of quantum many-body effects and entanglement through use of highly coherent and precisely controlled optical lattice clocks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martin, M J -- Bishof, M -- Swallows, M D -- Zhang, X -- Benko, C -- von-Stecher, J -- Gorshkov, A V -- Rey, A M -- Ye, Jun -- New York, N.Y. -- Science. 2013 Aug 9;341(6146):632-6. doi: 10.1126/science.1236929.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉JILA, National Institute of Standards and Technology and University of Colorado, Boulder, CO 80309, USA. mjmartin@caltech.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23929976" target="_blank"〉PubMed〈/a〉
