Differential effect of auxotrophies on the release of macromolecules by Salmonella enterica vaccine strainsHolger Loessner
Molecular Immunology, Helmholtz Centre for Infection Research, Inhoffenstrasse 7, 38124 Braunschweig, Germany
FEMS Microbiol Lett 265:81-8. 2006..Thus, the release of macromolecules from the bacterial carrier occurs as a consequence of appropriate lethal attenuation. This might substitute for sophisticated secretion systems...
Remote control of tumour-targeted Salmonella enterica serovar Typhimurium by the use of L-arabinose as inducer of bacterial gene expression in vivoHolger Loessner
Molecular Immunology, Helmholtz Centre for Infection Research, Inhoffenstrasse 7, 38124 Braunschweig, Germany
Cell Microbiol 9:1529-37. 2007..The possibility to deliberately induce genes in bacterial carriers within the host should render them extremely powerful tools for tumour therapy...
Drug-inducible remote control of gene expression by probiotic Escherichia coli Nissle 1917 in intestine, tumor and gall bladder of miceHolger Loessner
Molecular Immunology, Helmholtz Centre for Infection Research, HZI, Inhoffenstrasse 7, 38124 Braunschweig, Germany
Microbes Infect 11:1097-105. 2009..Importantly, we also observed colonization of gall bladders of mice when EcN was administered systemically at high doses. Bacteria in this anatomical compartment remained accessible to remote control of bacterial gene expression...
Improving live attenuated bacterial carriers for vaccination and therapyHolger Loessner
Molecular Immunology, Helmholtz Centre for Infection Research, Inhoffenstr 7, D 38124 Braunschweig, Germany
Int J Med Microbiol 298:21-6. 2008..No background activity could be observed with P(BAD) such that an inducible suicide gene could be introduced. This is adding an important safety feature to such live attenuated carrier bacteria...
Biofilm formation by Salmonella enterica serovar Typhimurium colonizing solid tumoursKatja Crull
Molecular Immunology, HZI Helmholtz Centre for Infection Research, Inhoffenstr 7, D 38124 Braunschweig, Germany
Cell Microbiol 13:1223-33. 2011..Thus, tumour colonizing S. typhimurium might form biofilms as protection against phagocytosis. Since other bacteria are behaving similarly, solid murine tumours might represent a unique model to study biofilm formation in vivo...
Identification of tumor-specific Salmonella Typhimurium promoters and their regulatory logicSara Leschner
Molecular Immunology, Helmholtz Centre for Infection Research, Inhoffenstr 7, 38124 Braunschweig, Germany
Nucleic Acids Res 40:2984-94. 2012..Now, such tumor-specific promoters can be used to safely express therapeutic proteins by tumor-colonizing S. Typhimurium directly in the neoplasia...
Containment of tumor-colonizing bacteria by host neutrophilsKathrin Westphal
Molecular Immunology, Helmholtz Center for Infection Research, Braunschweig, Germany
Cancer Res 68:2952-60. 2008..Thus, bacteria-mediated tumor therapy can be amplified by depletion of host neutrophils...
Tumor invasion of Salmonella enterica serovar Typhimurium is accompanied by strong hemorrhage promoted by TNF-alphaSara Leschner
Molecular Immunology, HZI Helmholtz Centre for Infection Research, Braunschweig, Germany
PLoS ONE 4:e6692. 2009..How they efficiently find and invade the tumors is still unclear. However, this is an important issue to be clarified when bacteria should be tailored for application in cancer therapy...
Biofilm formation by Pseudomonas aeruginosa in solid murine tumors - a novel model systemUliana Komor
Molecular Immunology, Helmholtz Center for Infection Research, Inhoffenstrasse 7, Braunschweig 38124, Germany
Microbes Infect 14:951-8. 2012....
