MetabolomicsAdaptive laboratory evolution of microbial co-cultures for improved metabolite secretion

Adaptive laboratory evolution has proven highly effective for obtaining microorganisms with enhanced capabilities. Yet, this method is inherently restricted to the traits that are positively linked to cell fitness, such as nutrient utilization. Here, we introduce coevolution of obligatory mutuali...

MetabolomicsMetabolic alterations in immune cells associate with progression to type 1 diabetes

AIMS: Previous metabolomics studies suggest that type 1 diabetes is preceded by specific metabolic disturbances. The aim of this study was to investigate whether distinct metabolic patterns occur in peripheral blood mononuclear cells (PBMCs) of children who later develop pancreat...

TranscriptomicsMacrophages recognize the Helicobacter pylori type IV secretion system in the absence of TLR signaling
Helicobacter pylori conquered the world by colonizing the human stomach. There are two major groups of strains, one with and one without a cag pathogenicity island (cagPAI), which result in different clinical outcomes with increased severity in cagPAI+ H. pylori infections such as higher inflammatio...

MetabolomicsMetabolomic analysis of riboswitch containing E. coli recombinant expression system
In this study we have employed metabolomics approaches to understand the metabolic effects of producing enhanced green fluorescent protein (eGFP) as a recombinant protein in Escherichia coli cells. This metabolic burden analysis was performed against a number of recombinant expression systems and co...

GenomicsThe PhoP-dependent ncRNA Mcr7 modulates the TAT secretion system in Mycobacterium tuberculosis [ChIP-Seq]
The PhoPR two-component system is essential for virulence in Mycobacterium tuberculosis where it controls expression of approximately 2% of the genes, including those for the ESX-1 secretion apparatus, a major virulence determinant. Mutations in phoP lead to compromised production of pathogen-specif...

ProteomicsStoichiometry of the bacterial type III secretion export apparatus
Bacterial type III secretion systems are cell envelope-spanning effector protein-delivery machines essential for colonization and survival of many Gram-negative pathogens and symbionts. The membrane-embedded core unit of these secretion systems is termed needle complex. The needle complex is compose...

TranscriptomicsGlobal impact of Salmonella type III secretion effector SteA on host cells
Salmonella enterica is a Gram-negative bacterium that causes gastroenteritis, bacteremia and typhoid fever in several animal species including humans. Its virulence is greatly dependent on two type III secretion systems (T3SSs), encoded in pathogenicity islands 1 (SPI1) and 2 (SPI2), respectively. T...

TranscriptomicsTranscription profiling of Mycobacterium bovis with pYUB412 and pRD1-2F9 genes knocked-in to investigate the ESX-1 secretion system
The dedicated secretion system ESX-1 of Mycobacterium tuberculosis encoded by the extended RD1 region (extRD1) assures export of the ESAT-6 protein and its partner, the 10 kDa culture filtrate protein CFP-10, and is missing from the vaccine strains M.bovis BCG and M.microti. Here, we systematically ...
