Murine Splenocytes Induce Severe Gastritis and Delayed-Type Hypersensitivity and Suppress Bacterial Colonization in Helicobacter pylori-Infected SCID Mice

Eaton, Kathryn A., Ringler, Susan R., Danon, Stephen J.

The goal of this study was to evaluate the role of host immunity in gastritis and epithelial damage due to Helicobacter pylori. Splenocytes from H. pylori-infected and uninfected C57BL/6 mice were...

Cure of Helicobacter pylori Infection and Resolution of Gastritis by Adoptive Transfer of Splenocytes in Mice

Eaton, Kathryn A., Mefford, Megan E.

Vaccination suppresses Helicobacter pylori colonization but does not cure infection. Furthermore, postvaccination gastritis, likely induced by enhanced host response to residual colonization, may...

Role of Helicobacter pylori cag Region Genes in Colonization and Gastritis in Two Animal Models

Eaton, Kathryn A., Kersulyte, Dange, Mefford, Megan, Danon, Stephen J., Krakowka, Steven, Berg, Douglas E.

The Helicobacter pylori chromosomal region known as the cytotoxin-gene associated pathogenicity island (cag PAI) is associated with severe disease and encodes proteins that are believed to induce...

Switching of Flagellar Motility in Helicobacter pylori by Reversible Length Variation of a Short Homopolymeric Sequence Repeat in fliP, a Gene Encoding a Basal Body Protein

Josenhans, Christine, Eaton, Kathryn A., Thevenot, Tracy, Suerbaum, Sebastian

The genome of Helicobacter pylori contains numerous simple nucleotide repeats that have been proposed to have regulatory functions and to compensate for the conspicuous dearth of master regulatory...

Differential Gene Expression from Two Transcriptional Units in the cag Pathogenicity Island of Helicobacter pylori

Joyce, Elizabeth A., Gilbert, Joanne V., Eaton, Kathryn A., Plaut, Andrew, Wright, Andrew

Infection with Helicobacter pylori strains containing the cag Pathogenicity Island (cag PAI) is strongly correlated with the development of severe gastric disease, including gastric and duodenal...

In Vivo Complementation of ureB Restores the Ability of Helicobacter pylori To Colonize

Eaton, Kathryn A., Gilbert, Joanne V., Joyce, Elizabeth A., Wanken, Amy E., Thevenot, Tracy, Baker, Patrick, ...

The objective of this study was to determine (i) if complementation of ureB-negative Helicobacter pylori restores colonization and (ii) if urease is a useful reporter for promoter activity in vivo....

The Entner-Doudoroff Pathway Has Little Effect on Helicobacter pylori Colonization of Mice

Wanken, Amy E., Conway, Tyrrell, Eaton, Kathryn A.

Helicobacter pylori mutants deficient in 6-phosphogluconate dehydratase (6PGD) were constructed. Colonization densities were lower and minimum infectious doses were higher for mutant strains than for...

Helicobacter acinonychis: Genetic and Rodent Infection Studies of a Helicobacter pylori-Like Gastric Pathogen of Cheetahs and Other Big Cats

Dailidiene, Daiva, Dailide, Giedrius, Ogura, Keiji, Zhang, Maojun, Mukhopadhyay, Asish K., Eaton, Kathryn A., ...

Insights into bacterium-host interactions and genome evolution can emerge from comparisons among related species. Here we studied Helicobacter acinonychis (formerly H. acinonyx), a species closely...

Modulation of Host Immune Responses by the Cytolethal Distending Toxin of Helicobacter hepaticus

Pratt, Jason S., Sachen, Kacey L., Wood, Heather D., Eaton, Kathryn A., Young, Vincent B.

Persistent murine infection with Helicobacter hepaticus leads to chronic gastrointestinal inflammation and neoplasia in susceptible strains. To determine the role of the virulence factor cytolethal...

Role of Transcription Factor T-bet Expression by CD4+ Cells in Gastritis Due to Helicobacter pylori in Mice

Eaton, Kathryn A., Benson, Lucy H., Haeger, Jennifer, Gray, Brian M.

Gastritis due to Helicobacter pylori is induced by a Th1-mediated response that is CD4 cell and gamma interferon (IFN-γ) dependent. T-bet is a transcription factor that directs differentiation of...
