    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: Biomass-degrading microorganisms use lytic polysaccharide monooxygenase (LPMO) enzymes to help digest cellulose, chitin, and starch. By cleaving otherwise inaccessible crystalline cellulose chains, these enzymes provide access to hydrolytic enzymes. LPMOs are of interest to biotechnology because efficient depolymerization of cellulose is a major bottleneck for the production of biologically based chemicals and fuels. On page 1098 of this issue, Kracher et al. (1) compare LPMO-reducing substrates in fungi from different taxonomic groups and lifestyles, based on both biochemical and genomic evidence. The results provide insights into reductive activation of LPMO that are important for developing more efficient industrial enzymes for lignocellulose biorefineries. Author: Angel T. Martínez

    Description: There is a long-standing controversy regarding the mechanisms that generate the functional subdivisions of the cerebral neocortex. One model proposes that thalamic axonal input specifies these subdivisions; the competing model postulates that patterning mechanisms intrinsic to the dorsal telencephalon generate neocortical regions. Gbx-2 mutant mice, whose thalamic differentiation is disrupted, were investigated. Despite the lack of cortical innervation by thalamic axons, neocortical region-specific gene expression (Cadherin-6, EphA-7, Id-2, and RZR-beta) developed normally. This provides evidence that patterning mechanisms intrinsic to the neocortex specify the basic organization of its functional subdivisions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miyashita-Lin, E M -- Hevner, R -- Wassarman, K M -- Martinez, S -- Rubenstein, J L -- NS34661-01A1/NS/NINDS NIH HHS/ -- R01 MH49428-01/MH/NIMH NIH HHS/ -- R01 MH51561-01A1/MH/NIMH NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1999 Aug 6;285(5429):906-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Nina Ireland Laboratory of Developmental Neurobiology, Department of Psychiatry, School of Medicine, University of California San Francisco, San Francisco, CA 94143-0984, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10436162" target="_blank"〉PubMed〈/a〉

    Description: Animals clearly choose what they eat and can even choose among chemically different sugars. The physiological and biochemical mechanisms that constrain feeding choices are largely unknown. In this study, European starlings (Sturnus vulgaris) preferred mixture solutions of D-glucose plus D-fructose to equimolar (double molar caloric value) solutions of sucrose. Intubation feeding of sucrose did not increase blood glucose levels. Sucrose is a useless energy source for these birds because they lack a single digestive enzyme (sucrase) on the small intestinal brush border membrane. However, the membranes possessed separate maltase and isomaltase disaccharidases. This expression pattern and expression patterns of membrane disaccharidases among mammals suggest a role for intestinal enzymes in the coevolutionary interactions between vertebrates and their plant food sources.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martinez del Rio, C -- Stevens, B R -- DK-38715/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1989 Feb 10;243(4892):794-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Florida, Gainesville 32611.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2916126" 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: Conical intersections play a critical role in excited-state dynamics of polyatomic molecules because they govern the reaction pathways of many nonadiabatic processes. However, ultrafast probes have lacked sufficient spatial resolution to image wave-packet trajectories through these intersections directly. Here, we present the simultaneous experimental characterization of one-photon and two-photon excitation channels in isolated CF 3 I molecules using ultrafast gas-phase electron diffraction. In the two-photon channel, we have mapped out the real-space trajectories of a coherent nuclear wave packet, which bifurcates onto two potential energy surfaces when passing through a conical intersection. In the one-photon channel, we have resolved excitation of both the umbrella and the breathing vibrational modes in the CF 3 fragment in multiple nuclear dimensions. These findings benchmark and validate ab initio nonadiabatic dynamics calculations.

    Description: The construction of multicellular organisms depends on stem cells-cells that can both regenerate and produce daughter cells that undergo differentiation. Here, we show that the gaseous messenger ethylene modulates cell division in the cells of the quiescent center, which act as a source of stem cells in the seedling root. The cells formed through these ethylene-induced divisions express quiescent center-specific genes and can repress differentiation of surrounding initial cells, showing that quiescence is not required for these cells to signal to adjacent stem cells. We propose that ethylene is part of a signaling pathway that modulates cell division in the quiescent center in the stem cell niche during the postembryonic development of the root system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ortega-Martinez, Olga -- Pernas, Monica -- Carol, Rachel J -- Dolan, Liam -- BBS/E/J/00000168/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2007 Jul 27;317(5837):507-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell and Developmental Biology, John Innes Centre, Norwich NR4 7UH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17656722" target="_blank"〉PubMed〈/a〉
