- A new C-type lectin similar to the human immunoreceptor DC-SIGN mediates symbiont acquisition by a marine nematodeSilvia Bulgheresi
Vienna Ecology Centre, Department of Marine Biology, University of Vienna, Althanstrasse 14, 1090 Vienna, Austria
Appl Environ Microbiol 72:2950-6. 2006..Our results provide a molecular link between bacterial symbionts and host-secreted mucus in a marine symbiosis and suggest conservation in the mechanisms of host-microbe interactions throughout the animal kingdom...
- Sequence variability of the pattern recognition receptor Mermaid mediates specificity of marine nematode symbiosesSilvia Bulgheresi
Department of Genetics in Ecology, University of Vienna, Austria
ISME J 5:986-98. 2011..This is the first report of the functional role of sequence variability in a microbe-associated molecular patterns receptor in a beneficial association...
- Growth in width and FtsZ ring longitudinal positioning in a gammaproteobacterial symbiontNikolaus Leisch
University of Vienna, Department of Genetics in Ecology, Althanstrasse 14, 1090 Vienna, Austria
Curr Biol 22:R831-2. 2012..Remarkably, the newly described FtsZ ring appears to be not only 90° shifted with respect to model rods, but also elliptical and discontinuous. This reveals an unexpected versatility of the gammaproteobacterial cytokinetic machinery...
- Bacterial symbiosis maintenance in the asexually reproducing and regenerating flatworm Paracatenula galateiaUlrich Dirks
Department of Marine Biology, University of Vienna, Vienna, Austria
PLoS ONE 7:e34709. 2012..This would justify both the codiversification between Paracatenula hosts and their Candidatus Riegeria symbionts, and the slow evolutionary rates observed for several symbiont genes...
- First detection of thiotrophic symbiont phylotypes in the pelagic marine environmentNiels R Heindl
Department of Genetics in Ecology, University of Vienna, Vienna, Austria
FEMS Microbiol Ecol 77:223-7. 2011..In either case, their existence sheds light on the evolution of beneficial symbioses between shallow water invertebrates and sulfur-oxidizing bacteria...
- Asynchronous division by non-ring FtsZ in the gammaproteobacterial symbiont of Robbea hypermnestraNikolaus Leisch
Department of Ecogenomics and Systems Biology, Archaeal Biology and Ecogenomics Division, University of Vienna, Althanstrasse 14, 1090 Vienna, Austria
Nat Microbiol 2:16182. 2016..We conclude that, in a naturally occurring animal symbiont, binary fission is host-oriented and does not require native FtsZ to polymerize into a ring at any septation stage...
- Size-independent symmetric division in extraordinarily long cellsNika Pende
1 Department of Ecogenomics and Systems Biology, University of Vienna, Althanstrasse 14, 1090 Vienna, Austria 2
Nat Commun 5:4803. 2014..In conclusion, the reproduction modes of two extraordinarily long bacterial cells indicate that size is not the primary trigger of division and that yet unknown mechanisms time the localization of both DNA and the septum...
- A complex journey: transmission of microbial symbiontsMonika Bright
University of Vienna, Department of Marine Biology, Althanstrasse 14, A 1090 Vienna, Austria
Nat Rev Microbiol 8:218-30. 2010..We also discuss how the two main transmission modes shape the evolution of the symbiotic partners...
- Paracatenula, an ancient symbiosis between thiotrophic Alphaproteobacteria and catenulid flatwormsHarald Ronald Gruber-Vodicka
Department of Marine Biology, University of Vienna, A 1090 Vienna, Austria
Proc Natl Acad Sci U S A 108:12078-83. 2011....
- C-type lectin Mermaid inhibits dendritic cell mediated HIV-1 transmission to CD4+ T cellsAlexey A Nabatov
Department of Molecular Cellular Biology and Immunology, VU University Medical Center, vd Boechorststraat 7, 1081 BT, Amsterdam, The Netherlands
Virology 378:323-8. 2008..The results are important for the anti-HIV-1 microbicide development directed at preventing DC-HIV-1 interactions...
- Human dendritic cell-specific intercellular adhesion molecule-grabbing nonintegrin (CD209) is a receptor for Yersinia pestis that promotes phagocytosis by dendritic cellsPei Zhang
Department of Biomedical Sciences, College of Medicine, University of Illinois at Chicago UIC, 1601 Parkview Avenue, Rockford, IL 61107, USA
Infect Immun 76:2070-9. 2008..pestis and human DCs can be reduced by a combination treatment with anti-CD209 and anti-CD207 antibodies. This study shows that human DC-SIGN is a receptor for Y. pestis that promotes phagocytosis by DCs in vitro...
- Role of N-acetylglucosamine within core lipopolysaccharide of several species of gram-negative bacteria in targeting the DC-SIGN (CD209)Pei Zhang
Department of Biomedical Sciences, College of Medicine, University of Illinois at Chicago, Rockford, IL 61107, USA
J Immunol 177:4002-11. 2006..Our results also imply that DC-SIGN is an innate immune receptor and the interaction of bacterial core LPS and DC-SIGN may represent a primeval interaction between Gram-negative bacteria and host phagocytic cells...
