    Host genetic diversity enables Ebola hemorrhagic fever pathogenesis and resistance (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-11-02
    Description: Existing mouse models of lethal Ebola virus infection do not reproduce hallmark symptoms of Ebola hemorrhagic fever, neither delayed blood coagulation and disseminated intravascular coagulation nor death from shock, thus restricting pathogenesis studies to nonhuman primates. Here we show that mice from the Collaborative Cross panel of recombinant inbred mice exhibit distinct disease phenotypes after mouse-adapted Ebola virus infection. Phenotypes range from complete resistance to lethal disease to severe hemorrhagic fever characterized by prolonged coagulation times and 100% mortality. Inflammatory signaling was associated with vascular permeability and endothelial activation, and resistance to lethal infection arose by induction of lymphocyte differentiation and cellular adhesion, probably mediated by the susceptibility allele Tek. These data indicate that genetic background determines susceptibility to Ebola hemorrhagic fever.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4241145/" 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/PMC4241145/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rasmussen, Angela L -- Okumura, Atsushi -- Ferris, Martin T -- Green, Richard -- Feldmann, Friederike -- Kelly, Sara M -- Scott, Dana P -- Safronetz, David -- Haddock, Elaine -- LaCasse, Rachel -- Thomas, Matthew J -- Sova, Pavel -- Carter, Victoria S -- Weiss, Jeffrey M -- Miller, Darla R -- Shaw, Ginger D -- Korth, Marcus J -- Heise, Mark T -- Baric, Ralph S -- de Villena, Fernando Pardo-Manuel -- Feldmann, Heinz -- Katze, Michael G -- P51 OD010425/OD/NIH HHS/ -- U19 AI100625/AI/NIAID NIH HHS/ -- U19 AI109761/AI/NIAID NIH HHS/ -- U54 AI081680/AI/NIAID NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2014 Nov 21;346(6212):987-91. doi: 10.1126/science.1259595.

    Acquisition of a multifunctional IgA+ plasma cell phenotype in the gut (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-12-14
    Description: The largest mucosal surface in the body is in the gastrointestinal tract, a location that is heavily colonized by microbes that are normally harmless. A key mechanism required for maintaining a homeostatic balance between this microbial burden and the lymphocytes that densely populate the gastrointestinal tract is the production and transepithelial transport of poly-reactive IgA (ref. 1). Within the mucosal tissues, B cells respond to cytokines, sometimes in the absence of T-cell help, undergo class switch recombination of their immunoglobulin receptor to IgA, and differentiate to become plasma cells. However, IgA-secreting plasma cells probably have additional attributes that are needed for coping with the tremendous bacterial load in the gastrointestinal tract. Here we report that mouse IgA(+) plasma cells also produce the antimicrobial mediators tumour-necrosis factor-alpha (TNF-alpha) and inducible nitric oxide synthase (iNOS), and express many molecules that are commonly associated with monocyte/granulocytic cell types. The development of iNOS-producing IgA(+) plasma cells can be recapitulated in vitro in the presence of gut stroma, and the acquisition of this multifunctional phenotype in vivo and in vitro relies on microbial co-stimulation. Deletion of TNF-alpha and iNOS in B-lineage cells resulted in a reduction in IgA production, altered diversification of the gut microbiota and poor clearance of a gut-tropic pathogen. These findings reveal a novel adaptation to maintaining homeostasis in the gut, and extend the repertoire of protective responses exhibited by some B-lineage cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3487691/" 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/PMC3487691/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fritz, Jorg H -- Rojas, Olga Lucia -- Simard, Nathalie -- McCarthy, Douglas D -- Hapfelmeier, Siegfried -- Rubino, Stephen -- Robertson, Susan J -- Larijani, Mani -- Gosselin, Jean -- Ivanov, Ivaylo I -- Martin, Alberto -- Casellas, Rafael -- Philpott, Dana J -- Girardin, Stephen E -- McCoy, Kathy D -- Macpherson, Andrew J -- Paige, Christopher J -- Gommerman, Jennifer L -- 67157-3/Canadian Institutes of Health Research/Canada -- 89783-2/Canadian Institutes of Health Research/Canada -- MOP 114972/Canadian Institutes of Health Research/Canada -- MOP 67157/Canadian Institutes of Health Research/Canada -- MOP 89783/Canadian Institutes of Health Research/Canada -- MOP 9862/Canadian Institutes of Health Research/Canada -- R00 DK085329/DK/NIDDK NIH HHS/ -- R00 DK085329-02/DK/NIDDK NIH HHS/ -- Z01 AR041148-03/Intramural NIH HHS/ -- ZIA AR041148-08/Intramural NIH HHS/ -- England -- Nature. 2011 Dec 11;481(7380):199-203. doi: 10.1038/nature10698.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Immunology, University of Toronto, Toronto M5S 1A8, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22158124" target="_blank"〉PubMed〈/a〉

    Ultraviolet-radiation-induced inflammation promotes angiotropism and metastasis in melanoma (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-02-28
    Description: Intermittent intense ultraviolet (UV) exposure represents an important aetiological factor in the development of malignant melanoma. The ability of UV radiation to cause tumour-initiating DNA mutations in melanocytes is now firmly established, but how the microenvironmental effects of UV radiation influence melanoma pathogenesis is not fully understood. Here we report that repetitive UV exposure of primary cutaneous melanomas in a genetically engineered mouse model promotes metastatic progression, independent of its tumour-initiating effects. UV irradiation enhanced the expansion of tumour cells along abluminal blood vessel surfaces and increased the number of lung metastases. This effect depended on the recruitment and activation of neutrophils, initiated by the release of high mobility group box 1 (HMGB1) from UV-damaged epidermal keratinocytes and driven by Toll-like receptor 4 (TLR4). The UV-induced neutrophilic inflammatory response stimulated angiogenesis and promoted the ability of melanoma cells to migrate towards endothelial cells and use selective motility cues on their surfaces. Our results not only reveal how UV irradiation of epidermal keratinocytes is sensed by the innate immune system, but also show that the resulting inflammatory response catalyses reciprocal melanoma-endothelial cell interactions leading to perivascular invasion, a phenomenon originally described as angiotropism in human melanomas by histopathologists. Angiotropism represents a hitherto underappreciated mechanism of metastasis that also increases the likelihood of intravasation and haematogenous dissemination. Consistent with our findings, ulcerated primary human melanomas with abundant neutrophils and reactive angiogenesis frequently show angiotropism and a high risk for metastases. Our work indicates that targeting the inflammation-induced phenotypic plasticity of melanoma cells and their association with endothelial cells represent rational strategies to specifically interfere with metastatic progression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bald, Tobias -- Quast, Thomas -- Landsberg, Jennifer -- Rogava, Meri -- Glodde, Nicole -- Lopez-Ramos, Dorys -- Kohlmeyer, Judith -- Riesenberg, Stefanie -- van den Boorn-Konijnenberg, Debby -- Homig-Holzel, Cornelia -- Reuten, Raphael -- Schadow, Benjamin -- Weighardt, Heike -- Wenzel, Daniela -- Helfrich, Iris -- Schadendorf, Dirk -- Bloch, Wilhelm -- Bianchi, Marco E -- Lugassy, Claire -- Barnhill, Raymond L -- Koch, Manuel -- Fleischmann, Bernd K -- Forster, Irmgard -- Kastenmuller, Wolfgang -- Kolanus, Waldemar -- Holzel, Michael -- Gaffal, Evelyn -- Tuting, Thomas -- England -- Nature. 2014 Mar 6;507(7490):109-13. doi: 10.1038/nature13111.

    In vivo genome editing restores haemostasis in a mouse model of haemophilia (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-06-28
    Description: Editing of the human genome to correct disease-causing mutations is a promising approach for the treatment of genetic disorders. Genome editing improves on simple gene-replacement strategies by effecting in situ correction of a mutant gene, thus restoring normal gene function under the control of endogenous regulatory elements and reducing risks associated with random insertion into the genome. Gene-specific targeting has historically been limited to mouse embryonic stem cells. The development of zinc finger nucleases (ZFNs) has permitted efficient genome editing in transformed and primary cells that were previously thought to be intractable to such genetic manipulation. In vitro, ZFNs have been shown to promote efficient genome editing via homology-directed repair by inducing a site-specific double-strand break (DSB) at a target locus, but it is unclear whether ZFNs can induce DSBs and stimulate genome editing at a clinically meaningful level in vivo. Here we show that ZFNs are able to induce DSBs efficiently when delivered directly to mouse liver and that, when co-delivered with an appropriately designed gene-targeting vector, they can stimulate gene replacement through both homology-directed and homology-independent targeted gene insertion at the ZFN-specified locus. The level of gene targeting achieved was sufficient to correct the prolonged clotting times in a mouse model of haemophilia B, and remained persistent after induced liver regeneration. Thus, ZFN-driven gene correction can be achieved in vivo, raising the possibility of genome editing as a viable strategy for the treatment of genetic disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3152293/" 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/PMC3152293/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Hojun -- Haurigot, Virginia -- Doyon, Yannick -- Li, Tianjian -- Wong, Sunnie Y -- Bhagwat, Anand S -- Malani, Nirav -- Anguela, Xavier M -- Sharma, Rajiv -- Ivanciu, Lacramiora -- Murphy, Samuel L -- Finn, Jonathan D -- Khazi, Fayaz R -- Zhou, Shangzhen -- Paschon, David E -- Rebar, Edward J -- Bushman, Frederic D -- Gregory, Philip D -- Holmes, Michael C -- High, Katherine A -- P01 HL064190/HL/NHLBI NIH HHS/ -- P01 HL064190-11A1/HL/NHLBI NIH HHS/ -- T32 HL007150/HL/NHLBI NIH HHS/ -- T32 HL007150-35/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2011 Jun 26;475(7355):217-21. doi: 10.1038/nature10177.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematology, CTRB 5000, Children's Hospital of Philadelphia, 3501 Civic Center Boulevard, Philadelphia, Pennsylvania 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21706032" target="_blank"〉PubMed〈/a〉

    Autistic-like behaviours and hyperactivity in mice lacking ProSAP1/Shank2 (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-06-16
    Description: Autism spectrum disorders comprise a range of neurodevelopmental disorders characterized by deficits in social interaction and communication, and by repetitive behaviour. Mutations in synaptic proteins such as neuroligins, neurexins, GKAPs/SAPAPs and ProSAPs/Shanks were identified in patients with autism spectrum disorder, but the causative mechanisms remain largely unknown. ProSAPs/Shanks build large homo- and heteromeric protein complexes at excitatory synapses and organize the complex protein machinery of the postsynaptic density in a laminar fashion. Here we demonstrate that genetic deletion of ProSAP1/Shank2 results in an early, brain-region-specific upregulation of ionotropic glutamate receptors at the synapse and increased levels of ProSAP2/Shank3. Moreover, ProSAP1/Shank2(-/-) mutants exhibit fewer dendritic spines and show reduced basal synaptic transmission, a reduced frequency of miniature excitatory postsynaptic currents and enhanced N-methyl-d-aspartate receptor-mediated excitatory currents at the physiological level. Mutants are extremely hyperactive and display profound autistic-like behavioural alterations including repetitive grooming as well as abnormalities in vocal and social behaviours. By comparing the data on ProSAP1/Shank2(-/-) mutants with ProSAP2/Shank3alphabeta(-/-) mice, we show that different abnormalities in synaptic glutamate receptor expression can cause alterations in social interactions and communication. Accordingly, we propose that appropriate therapies for autism spectrum disorders are to be carefully matched to the underlying synaptopathic phenotype.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schmeisser, Michael J -- Ey, Elodie -- Wegener, Stephanie -- Bockmann, Juergen -- Stempel, A Vanessa -- Kuebler, Angelika -- Janssen, Anna-Lena -- Udvardi, Patrick T -- Shiban, Ehab -- Spilker, Christina -- Balschun, Detlef -- Skryabin, Boris V -- Dieck, Susanne tom -- Smalla, Karl-Heinz -- Montag, Dirk -- Leblond, Claire S -- Faure, Philippe -- Torquet, Nicolas -- Le Sourd, Anne-Marie -- Toro, Roberto -- Grabrucker, Andreas M -- Shoichet, Sarah A -- Schmitz, Dietmar -- Kreutz, Michael R -- Bourgeron, Thomas -- Gundelfinger, Eckart D -- Boeckers, Tobias M -- England -- Nature. 2012 Apr 29;486(7402):256-60. doi: 10.1038/nature11015.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Anatomy and Cell Biology, Ulm University, 89081 Ulm, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22699619" target="_blank"〉PubMed〈/a〉

    Innate lymphoid cells promote anatomical containment of lymphoid-resident commensal bacteria (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-08
    Description: The mammalian intestinal tract is colonized by trillions of beneficial commensal bacteria that are anatomically restricted to specific niches. However, the mechanisms that regulate anatomical containment remain unclear. Here, we show that interleukin-22 (IL-22)-producing innate lymphoid cells (ILCs) are present in intestinal tissues of healthy mammals. Depletion of ILCs resulted in peripheral dissemination of commensal bacteria and systemic inflammation, which was prevented by administration of IL-22. Disseminating bacteria were identified as Alcaligenes species originating from host lymphoid tissues. Alcaligenes was sufficient to promote systemic inflammation after ILC depletion in mice, and Alcaligenes-specific systemic immune responses were associated with Crohn's disease and progressive hepatitis C virus infection in patients. Collectively, these data indicate that ILCs regulate selective containment of lymphoid-resident bacteria to prevent systemic inflammation associated with chronic diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3659421/" 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/PMC3659421/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sonnenberg, Gregory F -- Monticelli, Laurel A -- Alenghat, Theresa -- Fung, Thomas C -- Hutnick, Natalie A -- Kunisawa, Jun -- Shibata, Naoko -- Grunberg, Stephanie -- Sinha, Rohini -- Zahm, Adam M -- Tardif, Melanie R -- Sathaliyawala, Taheri -- Kubota, Masaru -- Farber, Donna L -- Collman, Ronald G -- Shaked, Abraham -- Fouser, Lynette A -- Weiner, David B -- Tessier, Philippe A -- Friedman, Joshua R -- Kiyono, Hiroshi -- Bushman, Frederic D -- Chang, Kyong-Mi -- Artis, David -- 2-P30 CA016520/CA/NCI NIH HHS/ -- AI061570/AI/NIAID NIH HHS/ -- AI074878/AI/NIAID NIH HHS/ -- AI083480/AI/NIAID NIH HHS/ -- AI087990/AI/NIAID NIH HHS/ -- AI095466/AI/NIAID NIH HHS/ -- AI095608/AI/NIAID NIH HHS/ -- AI47619/AI/NIAID NIH HHS/ -- K08 DK093784/DK/NIDDK NIH HHS/ -- K08-DK093784/DK/NIDDK NIH HHS/ -- P30 AI 045008/AI/NIAID NIH HHS/ -- P30DK50306/DK/NIDDK NIH HHS/ -- R01 AI061570/AI/NIAID NIH HHS/ -- R01 AI074878/AI/NIAID NIH HHS/ -- R01 AI095466/AI/NIAID NIH HHS/ -- R01 AI102942/AI/NIAID NIH HHS/ -- R21 AI083480/AI/NIAID NIH HHS/ -- R21 AI087990/AI/NIAID NIH HHS/ -- T32 AI007532/AI/NIAID NIH HHS/ -- T32 AI055428/AI/NIAID NIH HHS/ -- T32 RR007063/RR/NCRR NIH HHS/ -- T32-AI007532/AI/NIAID NIH HHS/ -- T32-AI055428/AI/NIAID NIH HHS/ -- T32-RR007063/RR/NCRR NIH HHS/ -- U01 AI095608/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2012 Jun 8;336(6086):1321-5. doi: 10.1126/science.1222551.

    Description: Brain-derived neurotrophic factor (BDNF) is a key positive regulator of neural plasticity, promoting, for example, the actions of stimulant drugs of abuse such as cocaine. We discovered a surprising opposite role for BDNF in countering responses to chronic morphine exposure. The suppression of BDNF in the ventral tegmental area (VTA) enhanced the ability of morphine to increase dopamine (DA) neuron excitability and promote reward. In contrast, optical stimulation of VTA DA terminals in nucleus accumbens (NAc) completely reversed the suppressive effect of BDNF on morphine reward. Furthermore, we identified numerous genes in the NAc, a major target region of VTA DA neurons, whose regulation by BDNF in the context of chronic morphine exposure mediated this counteractive function. These findings provide insight into the molecular basis of morphine-induced neuroadaptations in the brain's reward circuitry.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3547365/" 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/PMC3547365/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koo, Ja Wook -- Mazei-Robison, Michelle S -- Chaudhury, Dipesh -- Juarez, Barbara -- LaPlant, Quincey -- Ferguson, Deveroux -- Feng, Jian -- Sun, Haosheng -- Scobie, Kimberly N -- Damez-Werno, Diane -- Crumiller, Marshall -- Ohnishi, Yoshinori N -- Ohnishi, Yoko H -- Mouzon, Ezekiell -- Dietz, David M -- Lobo, Mary Kay -- Neve, Rachael L -- Russo, Scott J -- Han, Ming-Hu -- Nestler, Eric J -- K99 MH094405/MH/NIMH NIH HHS/ -- P01 DA008227/DA/NIDA NIH HHS/ -- R01 DA014133/DA/NIDA NIH HHS/ -- R01 MH092306/MH/NIMH NIH HHS/ -- T32 MH087004/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2012 Oct 5;338(6103):124-8. doi: 10.1126/science.1222265.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Fishberg Department of Neuroscience and Friedman Brain Institute, Mount Sinai School of Medicine, New York, NY 10029, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23042896" target="_blank"〉PubMed〈/a〉

Selivanov, and R. Tacik The time dependence of muon spin relaxation has been measured in high-purity aluminum and silver samples in a longitudinal 2 T magnetic field at room temperature, using the time-differential muon spin relaxation technique. For times greater than 10 ns, the shape fits well to a single exponential wit... [Phys. Rev. B 83, 205121] Published Fri May 20, 2011
