Helicobacter pylori VacA as a mitochondrial targeted pathogenic effector
… is poorly understood. The vacuolating cytotoxin (VacA) of the human gastric pathogen Helicobacter pylori localizes to and disrupts mitochondrial function. In order to evaluate mitochondrial targeting of VacA, VacA associated cellular compartments were isolated by magnetic based fractionation for …

Mechanical stratigraphy of the Vaca Muerta Formation, Neuquén Basin, Argentina
The Vaca Muerta offers an excellent opportunity to study field development at an early stage. The particularities of how best to characterize this play are developing, and various techniques and processes must be tested. Even in parts of the basin where wells are being drilled in rapid succession, …

Identification and Characterization of the Helicobacter Pylori Vacuolating Cytotoxin Receptor
… virulence factors, the vacuolating cytotoxin (VacA), which is the only known exotoxin released by H. pylori into the stomach of infected individuals, contributes to the pathogenesis of infection by directly modulating several important properties of host cells. To be effective, VacA, must bind …

Characterization of vacuolating cytotoxin A of helicobacter pylori in cell binding and cellular activity
… membrane sphingomyelin (SM) to be important for VacA cell surface binding, direct VacA-SM interactions, and intracellular activity, suggesting that SM is a receptor for VacA. More recent work from our lab has identified three proximally located residues, R552, W603, and R647, each situated in a …

Modulation of host metabolism by the human gastric pathogen Helicobacter pylori
… cellular homeostasis. Vacuolating cytotoxin A (VacA) is a pore-forming exotoxin of H. pylori, that, once secreted, enters the host cells and targets mitochondria. Previous studies revealed that VacA supports H. pylori colonization by altering host energy metabolism, specifically, by collapsing …

Molecular characterization of a sphingomyelin binding site in the vacuolating cytotoxin of H. pylori
… the Helicobacter pylori vacuolating cytotoxin (VacA). While the cellular receptor has been identified, the molecular basis of SM recognition remains unknown. Molecular modeling of unrelated SM-binding proteins suggests that specific binding occurs through tryptophan rich aromatic clusters …

Characterization of the Helicobacter pylori vacuolating cytotoxin mediated induction of mitochondrial cell death mechanism
The Helicobacter pylori vacuolating cytotoxin (VacA) is a paradigm for microbial virulence factors that target and disable host cell mitochondria. VacA intoxication triggers mitochondrial dysfunction and metabolic stress, but the mechanisms underlying these perturbations in mitochondrial function …

Electrofacies, elemental composition, and source rock characteristics along seismic reflectors of the Vaca Muerta Formation in the Loma La Lata area, Neuquen Basin, Argentina
The Vaca Muerta Formation is a fine-grained marine lithostratigraphic unit that was deposited during the Late Jurassic and Early Cretaceous in the Neuquén Basin of Argentina. Accommodation space was generated by back-arc subsidence of the crust as the Pacific Plate subducted beneath the South …
