    Description: Synapse formation is a process tightly controlled in space and time. How gene regulatory mechanisms specify spatial and temporal aspects of synapse formation is not well understood. In the nematode Caenorhabditis elegans, two subtypes of the D-type inhibitory motor neuron (MN) classes, the dorsal D (DD) and ventral D (VD) neurons, extend axons along both the dorsal and ventral nerve cords. The embryonically generated DD motor neurons initially innervate ventral muscles in the first (L1) larval stage and receive their synaptic input from cholinergic motor neurons in the dorsal cord. They rewire by the end of the L1 moult to innervate dorsal muscles and to be innervated by newly formed ventral cholinergic motor neurons. VD motor neurons develop after the L1 moult; they take over the innervation of ventral muscles and receive their synaptic input from dorsal cholinergic motor neurons. We show here that the spatiotemporal control of synaptic wiring of the D-type neurons is controlled by an intersectional transcriptional strategy in which the UNC-30 Pitx-type homeodomain transcription factor acts together, in embryonic and early larval stages, with the temporally controlled LIN-14 transcription factor to prevent premature synapse rewiring of the DD motor neurons and, together with the UNC-55 nuclear hormone receptor, to prevent aberrant VD synaptic wiring in later larval and adult stages. A key effector of this intersectional transcription factor combination is a novel synaptic organizer molecule, the single immunoglobulin domain protein OIG-1. OIG-1 is perisynaptically localized along the synaptic outputs of the D-type motor neurons in a temporally controlled manner and is required for appropriate selection of both pre- and post-synaptic partners.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Howell, Kelly -- White, John G -- Hobert, Oliver -- R01 NS039996/NS/NINDS NIH HHS/ -- R01 NS050266/NS/NINDS NIH HHS/ -- R01NS039996-05/NS/NINDS NIH HHS/ -- R01NS050266-03/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- Medical Research Council/United Kingdom -- England -- Nature. 2015 Jul 2;523(7558):83-7. doi: 10.1038/nature14545.

    Description: The "cancerized field" concept posits that cancer-prone cells in a given tissue share an oncogenic mutation, but only discreet clones within the field initiate tumors. Most benign nevi carry oncogenic BRAF(V600E) mutations but rarely become melanoma. The zebrafish crestin gene is expressed embryonically in neural crest progenitors (NCPs) and specifically reexpressed in melanoma. Live imaging of transgenic zebrafish crestin reporters shows that within a cancerized field (BRAF(V600E)-mutant; p53-deficient), a single melanocyte reactivates the NCP state, revealing a fate change at melanoma initiation in this model. NCP transcription factors, including sox10, regulate crestin expression. Forced sox10 overexpression in melanocytes accelerated melanoma formation, which is consistent with activation of NCP genes and super-enhancers leading to melanoma. Our work highlights NCP state reemergence as a key event in melanoma initiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaufman, Charles K -- Mosimann, Christian -- Fan, Zi Peng -- Yang, Song -- Thomas, Andrew J -- Ablain, Julien -- Tan, Justin L -- Fogley, Rachel D -- van Rooijen, Ellen -- Hagedorn, Elliott J -- Ciarlo, Christie -- White, Richard M -- Matos, Dominick A -- Puller, Ann-Christin -- Santoriello, Cristina -- Liao, Eric C -- Young, Richard A -- Zon, Leonard I -- HG002668/HG/NHGRI NIH HHS/ -- K08 AR061071/AR/NIAMS NIH HHS/ -- R01 CA103846/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Jan 29;351(6272):aad2197. doi: 10.1126/science.aad2197.

    Description: Despite the success of potent anti-retroviral drugs in controlling human immunodeficiency virus type 1 (HIV-1) infection, little progress has been made in generating an effective HIV-1 vaccine. Although passive transfer of anti-HIV-1 broadly neutralizing antibodies can protect mice or macaques against a single high-dose challenge with HIV or simian/human (SIV/HIV) chimaeric viruses (SHIVs) respectively, the long-term efficacy of a passive antibody transfer approach for HIV-1 has not been examined. Here we show, on the basis of the relatively long-term protection conferred by hepatitis A immune globulin, the efficacy of a single injection (20 mg kg(-1)) of four anti-HIV-1-neutralizing monoclonal antibodies (VRC01, VRC01-LS, 3BNC117, and 10-1074 (refs 9 - 12)) in blocking repeated weekly low-dose virus challenges of the clade B SHIVAD8. Compared with control animals, which required two to six challenges (median = 3) for infection, a single broadly neutralizing antibody infusion prevented virus acquisition for up to 23 weekly challenges. This effect depended on antibody potency and half-life. The highest levels of plasma-neutralizing activity and, correspondingly, the longest protection were found in monkeys administered the more potent antibodies 3BNC117 and 10-1074 (median = 13 and 12.5 weeks, respectively). VRC01, which showed lower plasma-neutralizing activity, protected for a shorter time (median = 8 weeks). The introduction of a mutation that extends antibody half-life into the crystallizable fragment (Fc) domain of VRC01 increased median protection from 8 to 14.5 weeks. If administered to populations at high risk of HIV-1 transmission, such an immunoprophylaxis regimen could have a major impact on virus transmission.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gautam, Rajeev -- Nishimura, Yoshiaki -- Pegu, Amarendra -- Nason, Martha C -- Klein, Florian -- Gazumyan, Anna -- Golijanin, Jovana -- Buckler-White, Alicia -- Sadjadpour, Reza -- Wang, Keyun -- Mankoff, Zachary -- Schmidt, Stephen D -- Lifson, Jeffrey D -- Mascola, John R -- Nussenzweig, Michel C -- Martin, Malcolm A -- AI-100148/AI/NIAID NIH HHS/ -- HHSN261200800001E/PHS HHS/ -- UM1 AI100663-01/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- Intramural NIH HHS/ -- England -- Nature. 2016 May 5;533(7601):105-9. doi: 10.1038/nature17677.

    Description: G-protein-coupled receptors (GPCRs) signal primarily through G proteins or arrestins. Arrestin binding to GPCRs blocks G protein interaction and redirects signalling to numerous G-protein-independent pathways. Here we report the crystal structure of a constitutively active form of human rhodopsin bound to a pre-activated form of the mouse visual arrestin, determined by serial femtosecond X-ray laser crystallography. Together with extensive biochemical and mutagenesis data, the structure reveals an overall architecture of the rhodopsin-arrestin assembly in which rhodopsin uses distinct structural elements, including transmembrane helix 7 and helix 8, to recruit arrestin. Correspondingly, arrestin adopts the pre-activated conformation, with a approximately 20 degrees rotation between the amino and carboxy domains, which opens up a cleft in arrestin to accommodate a short helix formed by the second intracellular loop of rhodopsin. This structure provides a basis for understanding GPCR-mediated arrestin-biased signalling and demonstrates the power of X-ray lasers for advancing the frontiers of structural biology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4521999/" 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/PMC4521999/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kang, Yanyong -- Zhou, X Edward -- Gao, Xiang -- He, Yuanzheng -- Liu, Wei -- Ishchenko, Andrii -- Barty, Anton -- White, Thomas A -- Yefanov, Oleksandr -- Han, Gye Won -- Xu, Qingping -- de Waal, Parker W -- Ke, Jiyuan -- Tan, M H Eileen -- Zhang, Chenghai -- Moeller, Arne -- West, Graham M -- Pascal, Bruce D -- Van Eps, Ned -- Caro, Lydia N -- Vishnivetskiy, Sergey A -- Lee, Regina J -- Suino-Powell, Kelly M -- Gu, Xin -- Pal, Kuntal -- Ma, Jinming -- Zhi, Xiaoyong -- Boutet, Sebastien -- Williams, Garth J -- Messerschmidt, Marc -- Gati, Cornelius -- Zatsepin, Nadia A -- Wang, Dingjie -- James, Daniel -- Basu, Shibom -- Roy-Chowdhury, Shatabdi -- Conrad, Chelsie E -- Coe, Jesse -- Liu, Haiguang -- Lisova, Stella -- Kupitz, Christopher -- Grotjohann, Ingo -- Fromme, Raimund -- Jiang, Yi -- Tan, Minjia -- Yang, Huaiyu -- Li, Jun -- Wang, Meitian -- Zheng, Zhong -- Li, Dianfan -- Howe, Nicole -- Zhao, Yingming -- Standfuss, Jorg -- Diederichs, Kay -- Dong, Yuhui -- Potter, Clinton S -- Carragher, Bridget -- Caffrey, Martin -- Jiang, Hualiang -- Chapman, Henry N -- Spence, John C H -- Fromme, Petra -- Weierstall, Uwe -- Ernst, Oliver P -- Katritch, Vsevolod -- Gurevich, Vsevolod V -- Griffin, Patrick R -- Hubbell, Wayne L -- Stevens, Raymond C -- Cherezov, Vadim -- Melcher, Karsten -- Xu, H Eric -- DK071662/DK/NIDDK NIH HHS/ -- EY005216/EY/NEI NIH HHS/ -- EY011500/EY/NEI NIH HHS/ -- GM073197/GM/NIGMS NIH HHS/ -- GM077561/GM/NIGMS NIH HHS/ -- GM095583/GM/NIGMS NIH HHS/ -- GM097463/GM/NIGMS NIH HHS/ -- GM102545/GM/NIGMS NIH HHS/ -- GM103310/GM/NIGMS NIH HHS/ -- GM104212/GM/NIGMS NIH HHS/ -- GM108635/GM/NIGMS NIH HHS/ -- P30EY000331/EY/NEI NIH HHS/ -- P41 GM103310/GM/NIGMS NIH HHS/ -- P41GM103393/GM/NIGMS NIH HHS/ -- P41RR001209/RR/NCRR NIH HHS/ -- P50 GM073197/GM/NIGMS NIH HHS/ -- P50 GM073210/GM/NIGMS NIH HHS/ -- R01 DK066202/DK/NIDDK NIH HHS/ -- R01 DK071662/DK/NIDDK NIH HHS/ -- R01 EY011500/EY/NEI NIH HHS/ -- R01 GM087413/GM/NIGMS NIH HHS/ -- R01 GM109955/GM/NIGMS NIH HHS/ -- S10 RR027270/RR/NCRR NIH HHS/ -- U54 GM094586/GM/NIGMS NIH HHS/ -- U54 GM094599/GM/NIGMS NIH HHS/ -- U54 GM094618/GM/NIGMS NIH HHS/ -- England -- Nature. 2015 Jul 30;523(7562):561-7. doi: 10.1038/nature14656.

    Description: Mass-screen-and-treat and targeted mass-drug-administration strategies are being considered as a means to interrupt transmission of Plasmodium falciparum malaria. However, the effectiveness of such strategies will depend on the extent to which current and future diagnostics are able to detect those individuals who are infectious to mosquitoes. We estimate the relationship between parasite density and onward infectivity using sensitive quantitative parasite diagnostics and mosquito feeding assays from Burkina Faso. We find that a diagnostic with a lower detection limit of 200 parasites per microlitre would detect 55% of the infectious reservoir (the combined infectivity to mosquitoes of the whole population weighted by how often each individual is bitten) whereas a test with a limit of 20 parasites per microlitre would detect 83% and 2 parasites per microlitre would detect 95% of the infectious reservoir. Using mathematical models, we show that increasing the diagnostic sensitivity from 200 parasites per microlitre (equivalent to microscopy or current rapid diagnostic tests) to 2 parasites per microlitre would increase the number of regions where transmission could be interrupted with a mass-screen-and-treat programme from an entomological inoculation rate below 1 to one of up to 4. The higher sensitivity diagnostic could reduce the number of treatment rounds required to interrupt transmission in areas of lower prevalence. We predict that mass-screen-and-treat with a highly sensitive diagnostic is less effective than mass drug administration owing to the prophylactic protection provided to uninfected individuals by the latter approach. In low-transmission settings such as those in Southeast Asia, we find that a diagnostic tool with a sensitivity of 20 parasites per microlitre may be sufficient for targeted mass drug administration because this diagnostic is predicted to identify a similar village population prevalence compared with that currently detected using polymerase chain reaction if treatment levels are high and screening is conducted during the dry season. Along with other factors, such as coverage, choice of drug, timing of the intervention, importation of infections, and seasonality, the sensitivity of the diagnostic can play a part in increasing the chance of interrupting transmission.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Slater, Hannah C -- Ross, Amanda -- Ouedraogo, Andre Lin -- White, Lisa J -- Nguon, Chea -- Walker, Patrick G T -- Ngor, Pengby -- Aguas, Ricardo -- Silal, Sheetal P -- Dondorp, Arjen M -- La Barre, Paul -- Burton, Robert -- Sauerwein, Robert W -- Drakeley, Chris -- Smith, Thomas A -- Bousema, Teun -- Ghani, Azra C -- 106698/Z/14/Z/Wellcome Trust/United Kingdom -- England -- Nature. 2015 Dec 3;528(7580):S94-101. doi: 10.1038/nature16040.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉MRC Centre for Outbreak Analysis and Modelling, Department of Infectious Disease Epidemiology, Faculty of Medicine, Imperial College London, Norfolk Place, London W2 1PG, UK. ; Swiss Tropical and Public Health Institute, Socinstrasse 57, 4002 Basel, Switzerland. ; University of Basel, Petersplatz 1, 4001 Basel, Switzerland. ; Institute for Disease Modelling, Bellevue, Washington 98005, USA. ; Department of Biomedical Sciences, Centre National de Recherche et de Formation sur le Paludisme, 01 B.P. 2208, Ouagadougou, Burkina Faso. ; Mahidol-Oxford Tropical Medicine Research Unit, Faculty of Tropical Medicine, Mahidol University, Bangkok 10400, Thailand. ; Centre for Tropical Medicine, Nuffield Department of Medicine, University of Oxford, Oxford OX3 7LJ, UK. ; National Malaria Center, Ministry of Health, Phnom Penh 12302, Cambodia. ; Department of Statistical Sciences, University of Cape Town, Rondebosch 7701, Cape Town, South Africa. ; PATH, 2201 Westlake Avenue, Seattle, Washington 98121, USA. ; Radboud University Medical Center, 6525 HP Nijmegen, the Netherlands. ; London School of Hygiene &Tropical Medicine, Keppel St, London WC1E 7HT, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26633771" target="_blank"〉PubMed〈/a〉

    Description: Human activities, especially conversion and degradation of habitats, are causing global biodiversity declines. How local ecological assemblages are responding is less clear--a concern given their importance for many ecosystem functions and services. We analysed a terrestrial assemblage database of unprecedented geographic and taxonomic coverage to quantify local biodiversity responses to land use and related changes. Here we show that in the worst-affected habitats, these pressures reduce within-sample species richness by an average of 76.5%, total abundance by 39.5% and rarefaction-based richness by 40.3%. We estimate that, globally, these pressures have already slightly reduced average within-sample richness (by 13.6%), total abundance (10.7%) and rarefaction-based richness (8.1%), with changes showing marked spatial variation. Rapid further losses are predicted under a business-as-usual land-use scenario; within-sample richness is projected to fall by a further 3.4% globally by 2100, with losses concentrated in biodiverse but economically poor countries. Strong mitigation can deliver much more positive biodiversity changes (up to a 1.9% average increase) that are less strongly related to countries' socioeconomic status.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Newbold, Tim -- Hudson, Lawrence N -- Hill, Samantha L L -- Contu, Sara -- Lysenko, Igor -- Senior, Rebecca A -- Borger, Luca -- Bennett, Dominic J -- Choimes, Argyrios -- Collen, Ben -- Day, Julie -- De Palma, Adriana -- Diaz, Sandra -- Echeverria-Londono, Susy -- Edgar, Melanie J -- Feldman, Anat -- Garon, Morgan -- Harrison, Michelle L K -- Alhusseini, Tamera -- Ingram, Daniel J -- Itescu, Yuval -- Kattge, Jens -- Kemp, Victoria -- Kirkpatrick, Lucinda -- Kleyer, Michael -- Correia, David Laginha Pinto -- Martin, Callum D -- Meiri, Shai -- Novosolov, Maria -- Pan, Yuan -- Phillips, Helen R P -- Purves, Drew W -- Robinson, Alexandra -- Simpson, Jake -- Tuck, Sean L -- Weiher, Evan -- White, Hannah J -- Ewers, Robert M -- Mace, Georgina M -- Scharlemann, Jorn P W -- Purvis, Andy -- BB/F017324/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- England -- Nature. 2015 Apr 2;520(7545):45-50. doi: 10.1038/nature14324.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉1] United Nations Environment Programme World Conservation Monitoring Centre, 219 Huntingdon Road, Cambridge CB3 0DL, UK.
