    Membrane trafficking. Nucleoside diphosphate kinases fuel dynamin superfamily proteins with GTP for membrane remodeling (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-06-28
    Description: Dynamin superfamily molecular motors use guanosine triphosphate (GTP) as a source of energy for membrane-remodeling events. We found that knockdown of nucleoside diphosphate kinases (NDPKs) NM23-H1/H2, which produce GTP through adenosine triphosphate (ATP)-driven conversion of guanosine diphosphate (GDP), inhibited dynamin-mediated endocytosis. NM23-H1/H2 localized at clathrin-coated pits and interacted with the proline-rich domain of dynamin. In vitro, NM23-H1/H2 were recruited to dynamin-induced tubules, stimulated GTP-loading on dynamin, and triggered fission in the presence of ATP and GDP. NM23-H4, a mitochondria-specific NDPK, colocalized with mitochondrial dynamin-like OPA1 involved in mitochondria inner membrane fusion and increased GTP-loading on OPA1. Like OPA1 loss of function, silencing of NM23-H4 but not NM23-H1/H2 resulted in mitochondrial fragmentation, reflecting fusion defects. Thus, NDPKs interact with and provide GTP to dynamins, allowing these motor proteins to work with high thermodynamic efficiency.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4601533/" 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/PMC4601533/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boissan, Mathieu -- Montagnac, Guillaume -- Shen, Qinfang -- Griparic, Lorena -- Guitton, Jerome -- Romao, Maryse -- Sauvonnet, Nathalie -- Lagache, Thibault -- Lascu, Ioan -- Raposo, Graca -- Desbourdes, Celine -- Schlattner, Uwe -- Lacombe, Marie-Lise -- Polo, Simona -- van der Bliek, Alexander M -- Roux, Aurelien -- Chavrier, Philippe -- 311536/European Research Council/International -- New York, N.Y. -- Science. 2014 Jun 27;344(6191):1510-5. doi: 10.1126/science.1253768.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut Curie, Research Center, Paris, France.

    Enteric bacteria promote human and mouse norovirus infection of B cells (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-11-08
    Description: The cell tropism of human noroviruses and the development of an in vitro infection model remain elusive. Although susceptibility to individual human norovirus strains correlates with an individual's histo-blood group antigen (HBGA) profile, the biological basis of this restriction is unknown. We demonstrate that human and mouse noroviruses infected B cells in vitro and likely in vivo. Human norovirus infection of B cells required the presence of HBGA-expressing enteric bacteria. Furthermore, mouse norovirus replication was reduced in vivo when the intestinal microbiota was depleted by means of oral antibiotic administration. Thus, we have identified B cells as a cellular target of noroviruses and enteric bacteria as a stimulatory factor for norovirus infection, leading to the development of an in vitro infection model for human noroviruses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4401463/" 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/PMC4401463/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jones, Melissa K -- Watanabe, Makiko -- Zhu, Shu -- Graves, Christina L -- Keyes, Lisa R -- Grau, Katrina R -- Gonzalez-Hernandez, Mariam B -- Iovine, Nicole M -- Wobus, Christiane E -- Vinje, Jan -- Tibbetts, Scott A -- Wallet, Shannon M -- Karst, Stephanie M -- R01 AI080611/AI/NIAID NIH HHS/ -- R21 AI103961/AI/NIAID NIH HHS/ -- T90 DE021990/DE/NIDCR NIH HHS/ -- T90 DE021990-02/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 2014 Nov 7;346(6210):755-9. doi: 10.1126/science.1257147.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Genetics and Microbiology, Emerging Pathogens Institute, College of Medicine, University of Florida, Gainesville, FL, USA. ; Department of Oral Biology, College of Dentistry, University of Florida, Gainesville, FL, USA.

    Optical control of muscle function by transplantation of stem cell-derived motor neurons in mice (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-04-05
    Description: Damage to the central nervous system caused by traumatic injury or neurological disorders can lead to permanent loss of voluntary motor function and muscle paralysis. Here, we describe an approach that circumvents central motor circuit pathology to restore specific skeletal muscle function. We generated murine embryonic stem cell-derived motor neurons that express the light-sensitive ion channel channelrhodopsin-2, which we then engrafted into partially denervated branches of the sciatic nerve of adult mice. These engrafted motor neurons not only reinnervated lower hind-limb muscles but also enabled their function to be restored in a controllable manner using optogenetic stimulation. This synthesis of regenerative medicine and optogenetics may be a successful strategy to restore muscle function after traumatic injury or disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bryson, J Barney -- Machado, Carolina Barcellos -- Crossley, Martin -- Stevenson, Danielle -- Bros-Facer, Virginie -- Burrone, Juan -- Greensmith, Linda -- Lieberam, Ivo -- 095589/Wellcome Trust/United Kingdom -- G0900585/Medical Research Council/United Kingdom -- G1001234/Biotechnology and Biological Sciences Research Council/United Kingdom -- MR/K000608/1/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2014 Apr 4;344(6179):94-7. doi: 10.1126/science.1248523.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Sobell Department of Motor Neuroscience and Movement Disorders, University College London (UCL) Institute of Neurology, London, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24700859" target="_blank"〉PubMed〈/a〉

    Highly multiplexed subcellular RNA sequencing in situ (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-03-01
    Description: Understanding the spatial organization of gene expression with single-nucleotide resolution requires localizing the sequences of expressed RNA transcripts within a cell in situ. Here, we describe fluorescent in situ RNA sequencing (FISSEQ), in which stably cross-linked complementary DNA (cDNA) amplicons are sequenced within a biological sample. Using 30-base reads from 8102 genes in situ, we examined RNA expression and localization in human primary fibroblasts with a simulated wound-healing assay. FISSEQ is compatible with tissue sections and whole-mount embryos and reduces the limitations of optical resolution and noisy signals on single-molecule detection. Our platform enables massively parallel detection of genetic elements, including gene transcripts and molecular barcodes, and can be used to investigate cellular phenotype, gene regulation, and environment in situ.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4140943/" 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/PMC4140943/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Je Hyuk -- Daugharthy, Evan R -- Scheiman, Jonathan -- Kalhor, Reza -- Yang, Joyce L -- Ferrante, Thomas C -- Terry, Richard -- Jeanty, Sauveur S F -- Li, Chao -- Amamoto, Ryoji -- Peters, Derek T -- Turczyk, Brian M -- Marblestone, Adam H -- Inverso, Samuel A -- Bernard, Amy -- Mali, Prashant -- Rios, Xavier -- Aach, John -- Church, George M -- GM080177/GM/NIGMS NIH HHS/ -- MH098977/MH/NIMH NIH HHS/ -- P50 HG005550/HG/NHGRI NIH HHS/ -- RC2 HL102815/HL/NHLBI NIH HHS/ -- RC2HL102815/HL/NHLBI NIH HHS/ -- T32 GM007753/GM/NIGMS NIH HHS/ -- T32 GM080177/GM/NIGMS NIH HHS/ -- U01 MH098977/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2014 Mar 21;343(6177):1360-3. doi: 10.1126/science.1250212.

    Structures of PI4KIIIbeta complexes show simultaneous recruitment of Rab11 and its effectors (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-05-31
    Description: Phosphatidylinositol 4-kinases (PI4Ks) and small guanosine triphosphatases (GTPases) are essential for processes that require expansion and remodeling of phosphatidylinositol 4-phosphate (PI4P)-containing membranes, including cytokinesis, intracellular development of malarial pathogens, and replication of a wide range of RNA viruses. However, the structural basis for coordination of PI4K, GTPases, and their effectors is unknown. Here, we describe structures of PI4Kbeta (PI4KIIIbeta) bound to the small GTPase Rab11a without and with the Rab11 effector protein FIP3. The Rab11-PI4KIIIbeta interface is distinct compared with known structures of Rab complexes and does not involve switch regions used by GTPase effectors. Our data provide a mechanism for how PI4KIIIbeta coordinates Rab11 and its effectors on PI4P-enriched membranes and also provide strategies for the design of specific inhibitors that could potentially target plasmodial PI4KIIIbeta to combat malaria.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4046302/" 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/PMC4046302/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burke, John E -- Inglis, Alison J -- Perisic, Olga -- Masson, Glenn R -- McLaughlin, Stephen H -- Rutaganira, Florentine -- Shokat, Kevan M -- Williams, Roger L -- MC_U105184308/Medical Research Council/United Kingdom -- PG/11/109/29247/British Heart Foundation/United Kingdom -- PG11/109/29247/British Heart Foundation/United Kingdom -- R01AI099245/AI/NIAID NIH HHS/ -- T32 GM064337/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 May 30;344(6187):1035-8. doi: 10.1126/science.1253397.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council (MRC) Laboratory of Molecular Biology, Cambridge CB2 0QH, UK. jeburke@uvic.ca rlw@mrc-lmb.cam.ac.uk. ; Medical Research Council (MRC) Laboratory of Molecular Biology, Cambridge CB2 0QH, UK. ; Howard Hughes Medical Institute and Department of Cellular and Molecular Pharmacology, University of California, San Francisco (UCSF), San Francisco, CA 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24876499" target="_blank"〉PubMed〈/a〉

    Systems biology. Accurate information transmission through dynamic biochemical signaling networks (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-12-17
    Description: Stochasticity inherent to biochemical reactions (intrinsic noise) and variability in cellular states (extrinsic noise) degrade information transmitted through signaling networks. We analyzed the ability of temporal signal modulation--that is, dynamics--to reduce noise-induced information loss. In the extracellular signal-regulated kinase (ERK), calcium (Ca(2+)), and nuclear factor kappa-B (NF-kappaB) pathways, response dynamics resulted in significantly greater information transmission capacities compared to nondynamic responses. Theoretical analysis demonstrated that signaling dynamics has a key role in overcoming extrinsic noise. Experimental measurements of information transmission in the ERK network under varying signal-to-noise levels confirmed our predictions and showed that signaling dynamics mitigate, and can potentially eliminate, extrinsic noise-induced information loss. By curbing the information-degrading effects of cell-to-cell variability, dynamic responses substantially increase the accuracy of biochemical signaling networks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Selimkhanov, Jangir -- Taylor, Brooks -- Yao, Jason -- Pilko, Anna -- Albeck, John -- Hoffmann, Alexander -- Tsimring, Lev -- Wollman, Roy -- P50 GM085764/GM/NIGMS NIH HHS/ -- P50-GM085764/GM/NIGMS NIH HHS/ -- R01 GM089976/GM/NIGMS NIH HHS/ -- R01-GM071573/GM/NIGMS NIH HHS/ -- R01-GM089976/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Dec 12;346(6215):1370-3. doi: 10.1126/science.1254933.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Bioengineering, University of California-San Diego, La Jolla, CA 92093, USA. ; Department of Chemistry and Biochemistry, University of California-San Diego, La Jolla, CA 92093, USA. ; Department of Molecular and Cellular Biology, University of California-Davis, Davis 95616, USA. ; San Diego Center for Systems Biology, La Jolla, CA 92093, USA.

    Virus entry. Lassa virus entry requires a trigger-induced receptor switch (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-06-28
    Description: Lassa virus spreads from a rodent to humans and can lead to lethal hemorrhagic fever. Despite its broad tropism, chicken cells were reported 30 years ago to resist infection. We found that Lassa virus readily engaged its cell-surface receptor alpha-dystroglycan in avian cells, but virus entry in susceptible species involved a pH-dependent switch to an intracellular receptor, the lysosome-resident protein LAMP1. Iterative haploid screens revealed that the sialyltransferase ST3GAL4 was required for the interaction of the virus glycoprotein with LAMP1. A single glycosylated residue in LAMP1, present in susceptible species but absent in birds, was essential for interaction with the Lassa virus envelope protein and subsequent infection. The resistance of Lamp1-deficient mice to Lassa virus highlights the relevance of this receptor switch in vivo.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4239993/" 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/PMC4239993/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jae, Lucas T -- Raaben, Matthijs -- Herbert, Andrew S -- Kuehne, Ana I -- Wirchnianski, Ariel S -- Soh, Timothy K -- Stubbs, Sarah H -- Janssen, Hans -- Damme, Markus -- Saftig, Paul -- Whelan, Sean P -- Dye, John M -- Brummelkamp, Thijn R -- AI081842/AI/NIAID NIH HHS/ -- AI109740/AI/NIAID NIH HHS/ -- R01 AI081842/AI/NIAID NIH HHS/ -- T32 AI007245/AI/NIAID NIH HHS/ -- U19 AI109740/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2014 Jun 27;344(6191):1506-10. doi: 10.1126/science.1252480.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Netherlands Cancer Institute, Plesmanlaan 121, 1066 CX, Amsterdam, Netherlands. ; Netherlands Cancer Institute, Plesmanlaan 121, 1066 CX, Amsterdam, Netherlands.

    Description: Current antiviral agents can control but not eliminate hepatitis B virus (HBV), because HBV establishes a stable nuclear covalently closed circular DNA (cccDNA). Interferon-alpha treatment can clear HBV but is limited by systemic side effects. We describe how interferon-alpha can induce specific degradation of the nuclear viral DNA without hepatotoxicity and propose lymphotoxin-beta receptor activation as a therapeutic alternative. Interferon-alpha and lymphotoxin-beta receptor activation up-regulated APOBEC3A and APOBEC3B cytidine deaminases, respectively, in HBV-infected cells, primary hepatocytes, and human liver needle biopsies. HBV core protein mediated the interaction with nuclear cccDNA, resulting in cytidine deamination, apurinic/apyrimidinic site formation, and finally cccDNA degradation that prevented HBV reactivation. Genomic DNA was not affected. Thus, inducing nuclear deaminases-for example, by lymphotoxin-beta receptor activation-allows the development of new therapeutics that, in combination with existing antivirals, may cure hepatitis B.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lucifora, Julie -- Xia, Yuchen -- Reisinger, Florian -- Zhang, Ke -- Stadler, Daniela -- Cheng, Xiaoming -- Sprinzl, Martin F -- Koppensteiner, Herwig -- Makowska, Zuzanna -- Volz, Tassilo -- Remouchamps, Caroline -- Chou, Wen-Min -- Thasler, Wolfgang E -- Huser, Norbert -- Durantel, David -- Liang, T Jake -- Munk, Carsten -- Heim, Markus H -- Browning, Jeffrey L -- Dejardin, Emmanuel -- Dandri, Maura -- Schindler, Michael -- Heikenwalder, Mathias -- Protzer, Ulrike -- New York, N.Y. -- Science. 2014 Mar 14;343(6176):1221-8. doi: 10.1126/science.1243462.
