    Description: The extensive somatic diversification of immune receptors is a hallmark of higher vertebrates. However, whether molecular diversity contributes to immune protection in invertebrates is unknown. We present evidence that Drosophila immune-competent cells have the potential to express more than 18,000 isoforms of the immunoglobulin (Ig)-superfamily receptor Down syndrome cell adhesion molecule (Dscam). Secreted protein isoforms of Dscam were detected in the hemolymph, and hemocyte-specific loss of Dscam impaired the efficiency of phagocytic uptake of bacteria, possibly due to reduced bacterial binding. Importantly, the molecular diversity of Dscam transcripts generated through a mechanism of alternative splicing is highly conserved across major insect orders, suggesting an unsuspected molecular complexity of the innate immune system of insects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Watson, Fiona L -- Puttmann-Holgado, Roland -- Thomas, Franziska -- Lamar, David L -- Hughes, Michael -- Kondo, Masahiro -- Rebel, Vivienne I -- Schmucker, Dietmar -- 1RO1-NS46747-01/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2005 Sep 16;309(5742):1874-8.

    Description: The giant sarcomeric protein titin contains a protein kinase domain (TK) ideally positioned to sense mechanical load. We identified a signaling complex where TK interacts with the zinc-finger protein nbr1 through a mechanically inducible conformation. Nbr1 targets the ubiquitin-associated p62/SQSTM1 to sarcomeres, and p62 in turn interacts with MuRF2, a muscle-specific RING-B-box E3 ligase and ligand of the transactivation domain of the serum response transcription factor (SRF). Nuclear translocation of MuRF2 was induced by mechanical inactivity and caused reduction of nuclear SRF and repression of transcription. A human mutation in the titin protein kinase domain causes hereditary muscle disease by disrupting this pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lange, Stephan -- Xiang, Fengqing -- Yakovenko, Andrey -- Vihola, Anna -- Hackman, Peter -- Rostkova, Elena -- Kristensen, Jakob -- Brandmeier, Birgit -- Franzen, Gereon -- Hedberg, Birgitta -- Gunnarsson, Lars Gunnar -- Hughes, Simon M -- Marchand, Sylvie -- Sejersen, Thomas -- Richard, Isabelle -- Edstrom, Lars -- Ehler, Elisabeth -- Udd, Bjarne -- Gautel, Mathias -- G0200496(63216)/Medical Research Council/United Kingdom -- G0300213/Medical Research Council/United Kingdom -- PG/03/049/15364/British Heart Foundation/United Kingdom -- New York, N.Y. -- Science. 2005 Jun 10;308(5728):1599-603.

    Description: Social and ecological vulnerability to disasters and outcomes of any particular extreme event are influenced by buildup or erosion of resilience both before and after disasters occur. Resilient social-ecological systems incorporate diverse mechanisms for living with, and learning from, change and unexpected shocks. Disaster management requires multilevel governance systems that can enhance the capacity to cope with uncertainty and surprise by mobilizing diverse sources of resilience.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adger, W Neil -- Hughes, Terry P -- Folke, Carl -- Carpenter, Stephen R -- Rockstrom, Johan -- New York, N.Y. -- Science. 2005 Aug 12;309(5737):1036-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Tyndall Centre for Climate Change Research, School of Environmental Sciences, University of East Anglia, Norwich, NR4 7TJ, UK. n.adger@uea.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16099974" target="_blank"〉PubMed〈/a〉

    Description: Many bacterial pathogens rely on a conserved membrane histidine sensor kinase, QseC, to respond to host adrenergic signaling molecules and bacterial signals in order to promote the expression of virulence factors. Using a high-throughput screen, we identified a small molecule, LED209, that inhibits the binding of signals to QseC, preventing its autophosphorylation and consequently inhibiting QseC-mediated activation of virulence gene expression. LED209 is not toxic and does not inhibit pathogen growth; however, this compound markedly inhibits the virulence of several pathogens in vitro and in vivo in animals. Inhibition of signaling offers a strategy for the development of broad-spectrum antimicrobial drugs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2605406/" 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/PMC2605406/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rasko, David A -- Moreira, Cristiano G -- Li, De Run -- Reading, Nicola C -- Ritchie, Jennifer M -- Waldor, Matthew K -- Williams, Noelle -- Taussig, Ron -- Wei, Shuguang -- Roth, Michael -- Hughes, David T -- Huntley, Jason F -- Fina, Maggy W -- Falck, John R -- Sperandio, Vanessa -- P01 AI055637/AI/NIAID NIH HHS/ -- P01 AI055637-010005/AI/NIAID NIH HHS/ -- P01-AI055637-03/AI/NIAID NIH HHS/ -- R01 AI053067/AI/NIAID NIH HHS/ -- R01 AI053067-06/AI/NIAID NIH HHS/ -- R01 GM31278/GM/NIGMS NIH HHS/ -- R03 NS053582/NS/NINDS NIH HHS/ -- R03 NS053582-01/NS/NINDS NIH HHS/ -- R21 AI067827/AI/NIAID NIH HHS/ -- U01 AI077853/AI/NIAID NIH HHS/ -- U01 AI077853-01/AI/NIAID NIH HHS/ -- UO1-AI77853/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Aug 22;321(5892):1078-80. doi: 10.1126/science.1160354.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, University of Texas (UT) Southwestern Medical Center, Dallas, TX 75390, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18719281" target="_blank"〉PubMed〈/a〉
