    Description: Antibodies play a central role in immunity by forming an interface with the innate immune system and, typically, mediate proinflammatory activity. We describe a novel posttranslational modification that leads to anti-inflammatory activity of antibodies of immunoglobulin G, isotype 4 (IgG4). IgG4 antibodies are dynamic molecules that exchange Fab arms by swapping a heavy chain and attached light chain (half-molecule) with a heavy-light chain pair from another molecule, which results in bispecific antibodies. Mutagenesis studies revealed that the third constant domain is critical for this activity. The impact of IgG4 Fab arm exchange was confirmed in vivo in a rhesus monkey model with experimental autoimmune myasthenia gravis. IgG4 Fab arm exchange is suggested to be an important biological mechanism that provides the basis for the anti-inflammatory activity attributed to IgG4 antibodies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉van der Neut Kolfschoten, Marijn -- Schuurman, Janine -- Losen, Mario -- Bleeker, Wim K -- Martinez-Martinez, Pilar -- Vermeulen, Ellen -- den Bleker, Tamara H -- Wiegman, Luus -- Vink, Tom -- Aarden, Lucien A -- De Baets, Marc H -- van de Winkel, Jan G J -- Aalberse, Rob C -- Parren, Paul W H I -- New York, N.Y. -- Science. 2007 Sep 14;317(5844):1554-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Sanquin Research-AMC Landsteiner Laboratory, Department of Immunopathology, Plesmanlaan 125, 1066 CX Amsterdam, the Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17872445" target="_blank"〉PubMed〈/a〉

    Description: The imprints of domestication and breed development on the genomes of livestock likely differ from those of companion animals. A deep draft sequence assembly of shotgun reads from a single Hereford female and comparative sequences sampled from six additional breeds were used to develop probes to interrogate 37,470 single-nucleotide polymorphisms (SNPs) in 497 cattle from 19 geographically and biologically diverse breeds. These data show that cattle have undergone a rapid recent decrease in effective population size from a very large ancestral population, possibly due to bottlenecks associated with domestication, selection, and breed formation. Domestication and artificial selection appear to have left detectable signatures of selection within the cattle genome, yet the current levels of diversity within breeds are at least as great as exists within humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2735092/" 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/PMC2735092/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bovine HapMap Consortium -- Gibbs, Richard A -- Taylor, Jeremy F -- Van Tassell, Curtis P -- Barendse, William -- Eversole, Kellye A -- Gill, Clare A -- Green, Ronnie D -- Hamernik, Debora L -- Kappes, Steven M -- Lien, Sigbjorn -- Matukumalli, Lakshmi K -- McEwan, John C -- Nazareth, Lynne V -- Schnabel, Robert D -- Weinstock, George M -- Wheeler, David A -- Ajmone-Marsan, Paolo -- Boettcher, Paul J -- Caetano, Alexandre R -- Garcia, Jose Fernando -- Hanotte, Olivier -- Mariani, Paola -- Skow, Loren C -- Sonstegard, Tad S -- Williams, John L -- Diallo, Boubacar -- Hailemariam, Lemecha -- Martinez, Mario L -- Morris, Chris A -- Silva, Luiz O C -- Spelman, Richard J -- Mulatu, Woudyalew -- Zhao, Keyan -- Abbey, Colette A -- Agaba, Morris -- Araujo, Flabio R -- Bunch, Rowan J -- Burton, James -- Gorni, Chiara -- Olivier, Hanotte -- Harrison, Blair E -- Luff, Bill -- Machado, Marco A -- Mwakaya, Joel -- Plastow, Graham -- Sim, Warren -- Smith, Timothy -- Thomas, Merle B -- Valentini, Alessio -- Williams, Paul -- Womack, James -- Woolliams, John A -- Liu, Yue -- Qin, Xiang -- Worley, Kim C -- Gao, Chuan -- Jiang, Huaiyang -- Moore, Stephen S -- Ren, Yanru -- Song, Xing-Zhi -- Bustamante, Carlos D -- Hernandez, Ryan D -- Muzny, Donna M -- Patil, Shobha -- San Lucas, Anthony -- Fu, Qing -- Kent, Matthew P -- Vega, Richard -- Matukumalli, Aruna -- McWilliam, Sean -- Sclep, Gert -- Bryc, Katarzyna -- Choi, Jungwoo -- Gao, Hong -- Grefenstette, John J -- Murdoch, Brenda -- Stella, Alessandra -- Villa-Angulo, Rafael -- Wright, Mark -- Aerts, Jan -- Jann, Oliver -- Negrini, Riccardo -- Goddard, Mike E -- Hayes, Ben J -- Bradley, Daniel G -- Barbosa da Silva, Marcos -- Lau, Lilian P L -- Liu, George E -- Lynn, David J -- Panzitta, Francesca -- Dodds, Ken G -- R01 GM083606/GM/NIGMS NIH HHS/ -- R01 GM083606-02/GM/NIGMS NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 24;324(5926):528-32. doi: 10.1126/science.1167936.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19390050" target="_blank"〉PubMed〈/a〉

    Description: Gross inequities in disease burden between developed and developing countries are now the subject of intense global attention. Public and private donors have marshaled resources and created organizational structures to accelerate the development of new health products and to procure and distribute drugs and vaccines for the poor. Despite these encouraging efforts directed primarily from and funded by industrialized countries, sufficiency and sustainability remain enormous challenges because of the sheer magnitude of the problem. Here we highlight a complementary and increasingly important means to improve health equity: the growing ability of some developing countries to undertake health innovation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morel, Carlos M -- Acharya, Tara -- Broun, Denis -- Dangi, Ajit -- Elias, Christopher -- Ganguly, N K -- Gardner, Charles A -- Gupta, R K -- Haycock, Jane -- Heher, Anthony D -- Hotez, Peter J -- Kettler, Hannah E -- Keusch, Gerald T -- Krattiger, Anatole F -- Kreutz, Fernando T -- Lall, Sanjaya -- Lee, Keun -- Mahoney, Richard -- Martinez-Palomo, Adolfo -- Mashelkar, R A -- Matlin, Stephen A -- Mzimba, Mandi -- Oehler, Joachim -- Ridley, Robert G -- Senanayake, Pramilla -- Singer, Peter -- Yun, Mikyung -- New York, N.Y. -- Science. 2005 Jul 15;309(5733):401-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Technological Development in Health, Oswaldo Cruz Foundation (FIOCRUZ), Avenida Brasil 4365, Rio de Janeiro, RJ 21040-900, Brazil. morel@fiocruz.br〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16020723" target="_blank"〉PubMed〈/a〉

    Description: A block with a hitherto unknown system of writing has been found in the Olmec heartland of Veracruz, Mexico. Stylistic and other dating of the block places it in the early first millennium before the common era, the oldest writing in the New World, with features that firmly assign this pivotal development to the Olmec civilization of Mesoamerica.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rodriguez Martinez, Ma del Carmen -- Ortiz Ceballos, Ponciano -- Coe, Michael D -- Diehl, Richard A -- Houston, Stephen D -- Taube, Karl A -- Delgado Calderon, Alfredo -- New York, N.Y. -- Science. 2006 Sep 15;313(5793):1610-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centro del Instituto Nacional de Antropologia e Historia, Benito Juarez Numero 425-431, Veracruz, Mexico.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16973873" target="_blank"〉PubMed〈/a〉

    Description: Understanding why some people establish and maintain effective control of HIV-1 and others do not is a priority in the effort to develop new treatments for HIV/AIDS. Using a whole-genome association strategy, we identified polymorphisms that explain nearly 15% of the variation among individuals in viral load during the asymptomatic set-point period of infection. One of these is found within an endogenous retroviral element and is associated with major histocompatibility allele human leukocyte antigen (HLA)-B*5701, whereas a second is located near the HLA-C gene. An additional analysis of the time to HIV disease progression implicated two genes, one of which encodes an RNA polymerase I subunit. These findings emphasize the importance of studying human genetic variation as a guide to combating infectious agents.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1991296/" 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/PMC1991296/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fellay, Jacques -- Shianna, Kevin V -- Ge, Dongliang -- Colombo, Sara -- Ledergerber, Bruno -- Weale, Mike -- Zhang, Kunlin -- Gumbs, Curtis -- Castagna, Antonella -- Cossarizza, Andrea -- Cozzi-Lepri, Alessandro -- De Luca, Andrea -- Easterbrook, Philippa -- Francioli, Patrick -- Mallal, Simon -- Martinez-Picado, Javier -- Miro, Jose M -- Obel, Niels -- Smith, Jason P -- Wyniger, Josiane -- Descombes, Patrick -- Antonarakis, Stylianos E -- Letvin, Norman L -- McMichael, Andrew J -- Haynes, Barton F -- Telenti, Amalio -- Goldstein, David B -- G0200585/Medical Research Council/United Kingdom -- MC_U137884177/Medical Research Council/United Kingdom -- U19 AI067854/AI/NIAID NIH HHS/ -- U19 AI067854-03/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2007 Aug 17;317(5840):944-7.

    Description: The large majority of antibiotics currently used for treating infections and the antibiotic resistance genes acquired by human pathogens each have an environmental origin. Recent work indicates that the function of these elements in their environmental reservoirs may be very distinct from the "weapon-shield" role they play in clinical settings. Changes in natural ecosystems, including the release of large amounts of antimicrobials, might alter the population dynamics of microorganisms, including selection of resistance, with consequences for human health that are difficult to predict.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martinez, Jose L -- New York, N.Y. -- Science. 2008 Jul 18;321(5887):365-7. doi: 10.1126/science.1159483.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departamento de Biotecnologia Microbiana, Centro Nacional de Biotecnologia (CSIC), Darwin 3, Campus UAM, Cantoblanco, 28049-Madrid, and CIBERESP, Spain. jlmtnez@cnb.csic.es〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18635792" target="_blank"〉PubMed〈/a〉
