The ulcerogenic profile of Helicobacter pylori paediatric strains associated wi...

Helicobacter pylori infection is the major cause of paediatric peptic ulcer disease (PUD). In children with no other aetiology for the disease, this rare event occurs shortly after infection, presuming a still poorly understood higher susceptibility of the patient and highlighting the virulence of the implicated strain. Recently, we showed that the enhanced virulence of a group of paediatric ulcerogenic-strains...

Ulcerogenic Helicobacter pylori Strains Isolated from Children: A Contribution ...

Infection with Helicobacter pylori is the major cause for the development of peptic ulcer disease (PUD). In children, with no other etiology for the disease, this rare event occurs shortly after infection. In these young patients, habits of smoking, diet, consumption of alcohol and non-steroid anti-inflammatory drugs and stress, in addition to the genetic susceptibility of the patient, represent a minor influ...

Characterization of new human gastric epithelial cell lines

The lack of a cellular model which correctly mimics the natural niche of the pathogen Helicobacter pylori is still limitative for the study of this infection. Aiming to overcome this limitation, we have previously isolated clones of a subpopulation of the widely used heterogenic NCI-N87 (ATCC CRL-5822) gastric cell line1, those presenting typical epithelial markers and a progenitor-like phenotype (simultaneous ...
