TranscriptomicsTranscription profiling of human A549 pneumocyte cells infected with wild type and type III secretion system mutants of Pseudomonas aeruginosa
The bacterial type III secretion system (TTSS) is dedicated to directly effect host cell pathways by pathogens. In order to identify the key host responses of the various parts of the TTSS, we utilized expression profiling of a lung pneumocytes cell line, A549, exposed to various isogenic mutant str...

MetabolomicsSalmonella Typhimurium reprograms macrophage metabolism via T3SS effector SopE2 to promote intracellular replication and virulence

Salmonella Typhimurium establishes systemic infection by replicating in host macrophages. Here we show that macrophages infected with S. Typhimurium exhibit upregulated glycolysis and decreased serine synthesis, leading to accumulation of glycolytic intermediates. The effects on...

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...

ProteomicsQuantitative proteomic analysis of Burkholderia pseudomallei Bsa Type III secretion system effectors using hyper-secreting mutants
Burkholderia pseudomallei is an intracellular pathogen and the causative agent of melioidosis, a severe disease of humans and animals. One of the virulence factors critical for early stages of infection is the Burkholderia secretion apparatus (Bsa) Type 3 Secretion System (T3SS), a molecular syringe...

ProteomicsThe accessory type III secretion system effectors shape inflammatory infection outcome
Injection of effectors via a type III secretion system (T3SS) is an infection strategy shared by many Gram-negative bacterial pathogens. While individual T3SS effectors are well characterized, their network-level organization and the distinction between core and accessory effectors remain incomplete...

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...

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...

ProteomicsPlant signals anticipate the induction of the type III secretion system in Pseudomonas syringae 2 pv. actinidiae facilitating efficient temperature-dependent effector translocation
Disease resistance in plants depends on a molecular dialogue with microbes that involves many known chemical effectors, but the time course of the interaction and the influence of the environment are largely unknown. The outcome of host–pathogen interactions is thought to reflect the offensive and d...

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...

ProteomicsCytotoxicity and effector cooperation in the type III secretion system of Aeromonas schubertii
The type III secretion system (T3SS) is an important virulence factor of Gram-negative bacteria, including the genus Aeromonas, a group of aquatic bacteria capable of both mutualistic and pathogenic interactions. Aeromonas species are increasingly recognized as opportunistic human pathogens. The typ...
