    Description: Segmentation of the hindbrain and branchial region is a conserved feature of head development, involving the nested expression of Hox genes. Although it is presumed that vertebrate Hox genes function as segment identifiers, responsible for mediating registration between elements of diverse embryonic origin, this assumption has remained untested. To assess this, retroviral misexpression was combined with orthotopic grafting in chick embryos to generate a mismatch in Hox coding between a specific rhombomere and its corresponding branchial arch. Rhombomere-restricted misexpression of a single gene, Hoxb1, resulted in the homeotic transformation of the rhombomere, revealed by reorganization of motor axon projections.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bell, E -- Wingate, R J -- Lumsden, A -- N01-HD-7-3263/HD/NICHD NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1999 Jun 25;284(5423):2168-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Developmental Neurobiology, King's College London, Guy's Hospital, London SE1 9RT, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10381880" target="_blank"〉PubMed〈/a〉

    Description: The central themes of community ecology-distribution, abundance, and diversity-display strongly marked and very general patterns. These include the log-normal distribution of abundance, the relation between range and abundance, the species-area law, and the turnover of species composition. Each pattern is the subject of a large literature that interprets it in terms of ecological processes, typically involving the sorting of differently specialized species onto heterogeneous landscapes. All of these patterns can be shown to arise, however, from neutral community models in which all individuals have identical properties, as the consequence of local dispersal alone. This implies, at the least, that functional interpretations of these patterns must be reevaluated. More fundamentally, neutral community models provide a general theory for biodiversity and conservation biology capable of predicting the fundamental processes and patterns of community ecology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bell, G -- New York, N.Y. -- Science. 2001 Sep 28;293(5539):2413-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Redpath Museum, McGill University, Montreal, Quebec, Canada H3A 2K6. gbell2@po-box.mcgill.ca.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11577228" target="_blank"〉PubMed〈/a〉

    Description: Cell-cell signalling of semaphorin ligands through interaction with plexin receptors is important for the homeostasis and morphogenesis of many tissues and is widely studied for its role in neural connectivity, cancer, cell migration and immune responses. SEMA4D and Sema6A exemplify two diverse vertebrate, membrane-spanning semaphorin classes (4 and 6) that are capable of direct signalling through members of the two largest plexin classes, B and A, respectively. In the absence of any structural information on the plexin ectodomain or its interaction with semaphorins the extracellular specificity and mechanism controlling plexin signalling has remained unresolved. Here we present crystal structures of cognate complexes of the semaphorin-binding regions of plexins B1 and A2 with semaphorin ectodomains (human PLXNB1(1-2)-SEMA4D(ecto) and murine PlxnA2(1-4)-Sema6A(ecto)), plus unliganded structures of PlxnA2(1-4) and Sema6A(ecto). These structures, together with biophysical and cellular assays of wild-type and mutant proteins, reveal that semaphorin dimers independently bind two plexin molecules and that signalling is critically dependent on the avidity of the resulting bivalent 2:2 complex (monomeric semaphorin binds plexin but fails to trigger signalling). In combination, our data favour a cell-cell signalling mechanism involving semaphorin-stabilized plexin dimerization, possibly followed by clustering, which is consistent with previous functional data. Furthermore, the shared generic architecture of the complexes, formed through conserved contacts of the amino-terminal seven-bladed beta-propeller (sema) domains of both semaphorin and plexin, suggests that a common mode of interaction triggers all semaphorin-plexin based signalling, while distinct insertions within or between blades of the sema domains determine binding specificity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3587840/" 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/PMC3587840/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Janssen, Bert J C -- Robinson, Ross A -- Perez-Branguli, Francesc -- Bell, Christian H -- Mitchell, Kevin J -- Siebold, Christian -- Jones, E Yvonne -- 082301/Wellcome Trust/United Kingdom -- 083111/Wellcome Trust/United Kingdom -- 10976/Cancer Research UK/United Kingdom -- A10976/Cancer Research UK/United Kingdom -- A3964/Cancer Research UK/United Kingdom -- A5261/Cancer Research UK/United Kingdom -- G0700232/Medical Research Council/United Kingdom -- G0700232(82098)/Medical Research Council/United Kingdom -- G0900084/Medical Research Council/United Kingdom -- G9900061/Medical Research Council/United Kingdom -- G9900061(69203)/Medical Research Council/United Kingdom -- Cancer Research UK/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2010 Oct 28;467(7319):1118-22. doi: 10.1038/nature09468.

    Description: Transcriptional activation of cytokines, such as type-I interferons (interferon (IFN)-alpha and IFN-beta), constitutes the first line of antiviral defence. Here we show that translational control is critical for induction of type-I IFN production. In mouse embryonic fibroblasts lacking the translational repressors 4E-BP1 and 4E-BP2, the threshold for eliciting type-I IFN production is lowered. Consequently, replication of encephalomyocarditis virus, vesicular stomatitis virus, influenza virus and Sindbis virus is markedly suppressed. Furthermore, mice with both 4E- and 4E-BP2 genes (also known as Eif4ebp1 and Eif4ebp2, respectively) knocked out are resistant to vesicular stomatitis virus infection, and this correlates with an enhanced type-I IFN production in plasmacytoid dendritic cells and the expression of IFN-regulated genes in the lungs. The enhanced type-I IFN response in 4E-BP1-/- 4E-BP2-/- double knockout mouse embryonic fibroblasts is caused by upregulation of interferon regulatory factor 7 (Irf7) messenger RNA translation. These findings highlight the role of 4E-BPs as negative regulators of type-I IFN production, via translational repression of Irf7 mRNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Colina, Rodney -- Costa-Mattioli, Mauro -- Dowling, Ryan J O -- Jaramillo, Maritza -- Tai, Lee-Hwa -- Breitbach, Caroline J -- Martineau, Yvan -- Larsson, Ola -- Rong, Liwei -- Svitkin, Yuri V -- Makrigiannis, Andrew P -- Bell, John C -- Sonenberg, Nahum -- Howard Hughes Medical Institute/ -- England -- Nature. 2008 Mar 20;452(7185):323-8. doi: 10.1038/nature06730.

    Description: There exists controversy over the nature of haematopoietic progenitors of T cells. Most T cells develop in the thymus, but the lineage potential of thymus-colonizing progenitors is unknown. One approach to resolving this question is to determine the lineage potentials of the earliest thymic progenitors (ETPs). Previous work has shown that ETPs possess T and natural killer lymphoid potentials, and rare subsets of ETPs also possess B lymphoid potential, suggesting an origin from lymphoid-restricted progenitor cells. However, whether ETPs also possess myeloid potential is unknown. Here we show that nearly all ETPs in adult mice possess both T and myeloid potential in clonal assays. The existence of progenitors possessing T and myeloid potential within the thymus is incompatible with the current dominant model of haematopoiesis, in which T cells are proposed to arise from lymphoid-. Our results indicate that alternative models for lineage commitment during haematopoiesis must be considered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bell, J Jeremiah -- Bhandoola, Avinash -- England -- Nature. 2008 Apr 10;452(7188):764-7. doi: 10.1038/nature06840.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology and Laboratory Medicine, University of Pennsylvania School of Medicine, Philadelphia, Pennsylvania 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18401411" target="_blank"〉PubMed〈/a〉

    Description: Tribolium castaneum is a member of the most species-rich eukaryotic order, a powerful model organism for the study of generalized insect development, and an important pest of stored agricultural products. We describe its genome sequence here. This omnivorous beetle has evolved the ability to interact with a diverse chemical environment, as shown by large expansions in odorant and gustatory receptors, as well as P450 and other detoxification enzymes. Development in Tribolium is more representative of other insects than is Drosophila, a fact reflected in gene content and function. For example, Tribolium has retained more ancestral genes involved in cell-cell communication than Drosophila, some being expressed in the growth zone crucial for axial elongation in short-germ development. Systemic RNA interference in T. castaneum functions differently from that in Caenorhabditis elegans, but nevertheless offers similar power for the elucidation of gene function and identification of targets for selective insect control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tribolium Genome Sequencing Consortium -- Richards, Stephen -- Gibbs, Richard A -- Weinstock, George M -- Brown, Susan J -- Denell, Robin -- Beeman, Richard W -- Gibbs, Richard -- Bucher, Gregor -- Friedrich, Markus -- Grimmelikhuijzen, Cornelis J P -- Klingler, Martin -- Lorenzen, Marce -- Roth, Siegfried -- Schroder, Reinhard -- Tautz, Diethard -- Zdobnov, Evgeny M -- Muzny, Donna -- Attaway, Tony -- Bell, Stephanie -- Buhay, Christian J -- Chandrabose, Mimi N -- Chavez, Dean -- Clerk-Blankenburg, Kerstin P -- Cree, Andrew -- Dao, Marvin -- Davis, Clay -- Chacko, Joseph -- Dinh, Huyen -- Dugan-Rocha, Shannon -- Fowler, Gerald -- Garner, Toni T -- Garnes, Jeffrey -- Gnirke, Andreas -- Hawes, Alica -- Hernandez, Judith -- Hines, Sandra -- Holder, Michael -- Hume, Jennifer -- Jhangiani, Shalini N -- Joshi, Vandita -- Khan, Ziad Mohid -- Jackson, LaRonda -- Kovar, Christie -- Kowis, Andrea -- Lee, Sandra -- Lewis, Lora R -- Margolis, Jon -- Morgan, Margaret -- Nazareth, Lynne V -- Nguyen, Ngoc -- Okwuonu, Geoffrey -- Parker, David -- Ruiz, San-Juana -- Santibanez, Jireh -- Savard, Joel -- Scherer, Steven E -- Schneider, Brian -- Sodergren, Erica -- Vattahil, Selina -- Villasana, Donna -- White, Courtney S -- Wright, Rita -- Park, Yoonseong -- Lord, Jeff -- Oppert, Brenda -- Brown, Susan -- Wang, Liangjiang -- Weinstock, George -- Liu, Yue -- Worley, Kim -- Elsik, Christine G -- Reese, Justin T -- Elhaik, Eran -- Landan, Giddy -- Graur, Dan -- Arensburger, Peter -- Atkinson, Peter -- Beidler, Jim -- Demuth, Jeffery P -- Drury, Douglas W -- Du, Yu-Zhou -- Fujiwara, Haruhiko -- Maselli, Vincenza -- Osanai, Mizuko -- Robertson, Hugh M -- Tu, Zhijian -- Wang, Jian-jun -- Wang, Suzhi -- Song, Henry -- Zhang, Lan -- Werner, Doreen -- Stanke, Mario -- Morgenstern, Burkhard -- Solovyev, Victor -- Kosarev, Peter -- Brown, Garth -- Chen, Hsiu-Chuan -- Ermolaeva, Olga -- Hlavina, Wratko -- Kapustin, Yuri -- Kiryutin, Boris -- Kitts, Paul -- Maglott, Donna -- Pruitt, Kim -- Sapojnikov, Victor -- Souvorov, Alexandre -- Mackey, Aaron J -- Waterhouse, Robert M -- Wyder, Stefan -- Kriventseva, Evgenia V -- Kadowaki, Tatsuhiko -- Bork, Peer -- Aranda, Manuel -- Bao, Riyue -- Beermann, Anke -- Berns, Nicola -- Bolognesi, Renata -- Bonneton, Francois -- Bopp, Daniel -- Butts, Thomas -- Chaumot, Arnaud -- Denell, Robin E -- Ferrier, David E K -- Gordon, Cassondra M -- Jindra, Marek -- Lan, Que -- Lattorff, H Michael G -- Laudet, Vincent -- von Levetsow, Cornelia -- Liu, Zhenyi -- Lutz, Rebekka -- Lynch, Jeremy A -- da Fonseca, Rodrigo Nunes -- Posnien, Nico -- Reuter, Rolf -- Schinko, Johannes B -- Schmitt, Christian -- Schoppmeier, Michael -- Shippy, Teresa D -- Simonnet, Franck -- Marques-Souza, Henrique -- Tomoyasu, Yoshinori -- Trauner, Jochen -- Van der Zee, Maurijn -- Vervoort, Michel -- Wittkopp, Nadine -- Wimmer, Ernst A -- Yang, Xiaoyun -- Jones, Andrew K -- Sattelle, David B -- Ebert, Paul R -- Nelson, David -- Scott, Jeffrey G -- Muthukrishnan, Subbaratnam -- Kramer, Karl J -- Arakane, Yasuyuki -- Zhu, Qingsong -- Hogenkamp, David -- Dixit, Radhika -- Jiang, Haobo -- Zou, Zhen -- Marshall, Jeremy -- Elpidina, Elena -- Vinokurov, Konstantin -- Oppert, Cris -- Evans, Jay -- Lu, Zhiqiang -- Zhao, Picheng -- Sumathipala, Niranji -- Altincicek, Boran -- Vilcinskas, Andreas -- Williams, Michael -- Hultmark, Dan -- Hetru, Charles -- Hauser, Frank -- Cazzamali, Giuseppe -- Williamson, Michael -- Li, Bin -- Tanaka, Yoshiaki -- Predel, Reinhard -- Neupert, Susanne -- Schachtner, Joachim -- Verleyen, Peter -- Raible, Florian -- Walden, Kimberly K O -- Angeli, Sergio -- Foret, Sylvain -- Schuetz, Stefan -- Maleszka, Ryszard -- Miller, Sherry C -- Grossmann, Daniela -- BBS/B/12067/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBS/B/12067/2/Biotechnology and Biological Sciences Research Council/United Kingdom -- R01 GM058634/GM/NIGMS NIH HHS/ -- R01 HD029594/HD/NICHD NIH HHS/ -- R01 HD029594-16/HD/NICHD NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- Intramural NIH HHS/ -- England -- Nature. 2008 Apr 24;452(7190):949-55. doi: 10.1038/nature06784.

    Description: The odour of acids has a distinct quality that is perceived as sharp, pungent and often irritating. How acidity is sensed and translated into an appropriate behavioural response is poorly understood. Here we describe a functionally segregated population of olfactory sensory neurons in the fruitfly, Drosophila melanogaster, that are highly selective for acidity. These olfactory sensory neurons express IR64a, a member of the recently identified ionotropic receptor (IR) family of putative olfactory receptors. In vivo calcium imaging showed that IR64a+ neurons projecting to the DC4 glomerulus in the antennal lobe are specifically activated by acids. Flies in which the function of IR64a+ neurons or the IR64a gene is disrupted had defects in acid-evoked physiological and behavioural responses, but their responses to non-acidic odorants remained unaffected. Furthermore, artificial stimulation of IR64a+ neurons elicited avoidance responses. Taken together, these results identify cellular and molecular substrates for acid detection in the Drosophila olfactory system and support a labelled-line mode of acidity coding at the periphery.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3105465/" 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/PMC3105465/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ai, Minrong -- Min, Soohong -- Grosjean, Yael -- Leblanc, Charlotte -- Bell, Rati -- Benton, Richard -- Suh, Greg S B -- 1R01GM089746/GM/NIGMS NIH HHS/ -- F32 DC010936-01A1/DC/NIDCD NIH HHS/ -- R01 GM089746/GM/NIGMS NIH HHS/ -- England -- Nature. 2010 Dec 2;468(7324):691-5. doi: 10.1038/nature09537.

    Description: Sialic acid acetylesterase (SIAE) is an enzyme that negatively regulates B lymphocyte antigen receptor signalling and is required for the maintenance of immunological tolerance in mice. Heterozygous loss-of-function germline rare variants and a homozygous defective polymorphic variant of SIAE were identified in 24/923 subjects of European origin with relatively common autoimmune disorders and in 2/648 controls of European origin. All heterozygous loss-of-function SIAE mutations tested were capable of functioning in a dominant negative manner. A homozygous secretion-defective polymorphic variant of SIAE was catalytically active, lacked the ability to function in a dominant negative manner, and was seen in eight autoimmune subjects but in no control subjects. The odds ratio for inheriting defective SIAE alleles was 8.6 in all autoimmune subjects, 8.3 in subjects with rheumatoid arthritis, and 7.9 in subjects with type I diabetes. Functionally defective SIAE rare and polymorphic variants represent a strong genetic link to susceptibility in relatively common human autoimmune disorders.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2900412/" 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/PMC2900412/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Surolia, Ira -- Pirnie, Stephan P -- Chellappa, Vasant -- Taylor, Kendra N -- Cariappa, Annaiah -- Moya, Jesse -- Liu, Haoyuan -- Bell, Daphne W -- Driscoll, David R -- Diederichs, Sven -- Haider, Khaleda -- Netravali, Ilka -- Le, Sheila -- Elia, Roberto -- Dow, Ethan -- Lee, Annette -- Freudenberg, Jan -- De Jager, Philip L -- Chretien, Yves -- Varki, Ajit -- MacDonald, Marcy E -- Gillis, Tammy -- Behrens, Timothy W -- Bloch, Donald -- Collier, Deborah -- Korzenik, Joshua -- Podolsky, Daniel K -- Hafler, David -- Murali, Mandakolathur -- Sands, Bruce -- Stone, John H -- Gregersen, Peter K -- Pillai, Shiv -- AI 064930/AI/NIAID NIH HHS/ -- AI 068759/AI/NIAID NIH HHS/ -- AI 076505/AI/NIAID NIH HHS/ -- AR 022263/AR/NIAMS NIH HHS/ -- AR 044422/AR/NIAMS NIH HHS/ -- AR 058481/AR/NIAMS NIH HHS/ -- NS 32765/NS/NINDS NIH HHS/ -- P30 DK043351/DK/NIDDK NIH HHS/ -- R01 AI064930/AI/NIAID NIH HHS/ -- R01 AI064930-04/AI/NIAID NIH HHS/ -- R01 AI068759/AI/NIAID NIH HHS/ -- R01 AI068759-05/AI/NIAID NIH HHS/ -- R01 AI076505/AI/NIAID NIH HHS/ -- R01 AI076505-02/AI/NIAID NIH HHS/ -- R01 AR044422/AR/NIAMS NIH HHS/ -- R01 AR044422-13/AR/NIAMS NIH HHS/ -- RC1 AR058481/AR/NIAMS NIH HHS/ -- RC1 AR058481-01/AR/NIAMS NIH HHS/ -- England -- Nature. 2010 Jul 8;466(7303):243-7. doi: 10.1038/nature09115.
