Badea, Luminita, Beatson, Scott A, Kaparakis, Maria, Ferrero, Richard L, Hartland, Elizabeth L

Abstract Background Enteropathogenic Escherichia coli (EPEC) is an attaching and effacing (A/E) pathogen that possesses a type III secretion system (T3SS) encoded within the locus of enterocyte...

CD4+ CD25+ Regulatory T Cells Modulate the T-Cell and Antibody Responses in Helicobacter-Infected BALB/c Mice

Kaparakis, Maria, Laurie, Karen L., Wijburg, Odilia, Pedersen, John, Pearse, Martin, Van Driel, Ian R., ...

Gastric Helicobacter spp. induce chronic gastritis that may lead to ulceration and dysplasia. The host elicits a T helper 1 (Th1) response that is fundamental to the pathogenesis of these bacteria....

Chronic Helicobacter pylori Infection Does Not Significantly Alter the Microbiota of the Murine Stomach▿ †

Tan, Mai Ping, Kaparakis, Maria, Galic, Maja, Pedersen, John, Pearse, Martin, Wijburg, Odilia L. C., ...

We examined the impact of Helicobacter pylori infection on the murine gastric microbiota by culture and terminal-restriction fragment length polymorphism and found that neither acute nor chronic H....

Macrophages Are Mediators of Gastritis in Acute Helicobacter pylori Infection in C57BL/6 Mice▿

Kaparakis, Maria, Walduck, Anna K., Price, Jason D., Pedersen, John S., Van Rooijen, Nico, Pearse, Martin J., ...

Helicobacter pylori is the etiological agent of human chronic gastritis, a condition seen as a precursor to the development of gastrointestinal ulcers or gastric cancer. This study utilized the...

A Commensal Helicobacter sp. of the Rodent Intestinal Flora Activates TLR2 and NOD1 Responses in Epithelial Cells

Chaouche-Drider, Nadia, Kaparakis, Maria, Karrar, Abdulgader, Fernandez, Maria-Isabel, Carneiro, Letitia A. M., Viala, Jérôme, ...

Helicobacter spp. represent a proportionately small but significant component of the normal intestinal microflora of animal hosts. Several of these intestinal Helicobacter spp. are known to induce...
