“…CagF is much larger (32 kDa) than the average accessory protein (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15). Although the protein is acidic (theoretical pI ϳ4.5), CagF has an unusual amino acid composition: it is severely depleted in ala- nine and glycine residues with only ϳ3% of the protein being composed of them.…”

“…Helicobacter pylori reside within the human stomach. Most infected individuals remain asymptomatic for life, although in ϳ20% of people, H. pylori can cause severe diseases such as peptic ulcers, mucosa-associated lymphoid tissue lymphoma, and gastric adenocarcinoma (3)(4)(5). Specifically, H. pylori accounts for roughly 750,000 new cases of gastric cancer per year worldwide (6).…”

“…For quality control and comparative analysis, the antibiotics amoxicillin and metronidazole were also tested with each batch of plant extracts, as a positive control. For the animal studies, the cagA+ HP strain B128 was maintained as previously described (Israel et al 2001). …”

“…Colonies were identified as HP based on their characteristic morphology, and by urease and oxidase activities; colony counts were expressed as log CFU per stomach. Colonization density was determined by quantitative culture and acute inflammation and chronic inflammation (mononuclear cell infiltration independent from lymphoid follicles) were each graded from 0-3 in the gastric antrum, as previously described (Israel et al 2001; Table 1). …”

“…Des études cliniques révèlent que la présence de la protéine CagA est corrélée à l'évolutivité de la gastrite, à l'atrophie gastrique et au cancer [12,13]. Ces résultats ne sont pas retrouvés par tous les auteurs [14,15], mais une activation différen-tielle des voies de signalisation dans les cellules de l'hôte selon le contenu génétique des souches associées à des pathologies gastriques différentes a déjà été rapportée [16]. Il peut entraîner une gastrite mixte (touchant l'antre et le fundus), la sécrétion acide n'est pas modifiée et aucune maladie particulière (à l'exception de la dyspepsie non ulcéreuse) n'y est associée (voie 2): c'est la forme la plus fré-quente.…”
