Role of γ-glutamyltranspeptidase in the pathogenesis of Helicobacter suis and Helicobacter pylori infections
Helicobacter (H.) suis can colonize the stomach of pigs as well as humans, causing chronic gastritis and other gastric pathological changes including gastric ulceration and mucosa-associated lymphoid tissue (MALT) lymphoma. Recently, a virulence factor of H. suis, γ-glutamyl transpeptidase (GGT), has been demonstrated to play an important role in the induction of human gastric epithelial cell d...
متن کاملEvidence for Conserved Function of γ–Glutamyltranspeptidase in Helicobacter Genus
The confounding consequences of Helicobacter bilis infection in experimental mice populations are well recognized, but the role of this bacterium in human diseases is less known. Limited data are available on virulence determinants of this species. In Helicobacter pylori, γ-glutamyltranspeptidase (γGT) contributes to the colonization of the gastric mucosa and to the pathogenesis of peptic ulcer...
متن کاملAntibacterial activities of Galla rhois extracts against Helicobacter pylori infection
In this study, a medicinal plant, Galla rhois (GR), was examined and screened for its anti-Helicobacter pylori activity. Galla rhois was extracted with 70% ethanol. Inhibitory zone tests, as in vitro assays, and an in vivo study using a Mongolian gerbil (Meriones unguiculatus) model were performed. The safety of the GR extract was then evaluated in an animal study. The Galla rhois extract demon...
