چکیده

To determine the pathological significance of the coccoid form of Helicobacter pylori, its adhesion to and induction of secretion of interleukin-8 (IL-8) by gastric epithelial (MKN45) cells were studied. By flow cytometry, the adhesion of the coccoid form to MKN45 cells was significantly lower than that of the helical form. The monoclonal antibody A20 recognising lipopolysaccharide of H. pylori inhibited the adhesion of the coccoid form to MKN45 cells as much as that of the helical form. There was significantly lower induction of IL-8 secretion by MKN45 cells exposed to the coccoid form (two of four strains) as compared with the helical form.

Coccoid Helicobacter pylori Can Directly Adhere and Invade in Agminated Formation to Human Gastric Epithelial Cells

Helicobacter pylori (H. pylori) can infect into the epithelial cell to cause benign or malignant disorders. Under stressful environment, a spiral form of H. pylori is transformed into a coccoid form. The infectivity of the coccoid form is still controversial. Since spiral forms are transformed into two types of coccoid forms via different mechanisms, the infectivity of the two types of coccoid ...

Geranylgeranylacetone selectively binds to the HSP70 of Helicobacter pylori and alters its coccoid morphology

Geranylgeranylacetone (GGA) is used to treat patients suffering from peptic ulcers and gastritis. We examined the effect of GGA on Helicobacter pylori, which is a causative factor of gastrointestinal diseases. Previously, we have reported that GGA binds specifically to the molecular chaperone HSP70. In this paper, we report that GGA bounds to H. pylori HSP70 (product of the DnaK gene) with 26-t...

Effect of nitric oxide on Helicobacter pylori morphology.

Helicobacter pylori causes chronic gastritis punctuated with fluctuating episodes of acute distress that can lead to peptic ulcer disease. Several factors produced by the bacterium have been shown to initiate the inflammatory response, but mechanisms potentially involved in the down-regulation of inflammation have not been described. We show that nitric oxide (NO) released from synthetic NO gen...
