Helicobacter pylori arginase inhibits nitric oxide production by eukaryotic cells: A strategy for bacterial survival
Open accessAbstract
The antimicrobial effect of nitric oxide (NO) is an essential part of innate immunity. The vigorous host response to the human gastric pathogen Helicobacter pylori fails to eradicate the organism, despite up-regulation of inducible NO synthase (iNOS) in the gastric mucosa. Here we report that wild-type strains of H. pylori inhibit NO production by activated macrophages at physiologic concentrations of l-arginine, the common substrate for iNOS and arginase. Inactivation of the gene rocF, encoding constitutively expressed arginase in H. pylori, restored high-output NO production by macrophages. By using HPLC analysis, we show that l-arginine is effectively consumed in the culture medium by wild-type but not arginase-deficient H. pylori. The substantially higher levels of NO generated by macrophages cocultured with rocF-deficient H. pylori resulted in efficient killing of the bacteria, whereas wild-type H. pylori exhibited no loss of survival under these conditions. Killing of the arginase-deficient H. pylori was NO-dependent, because peritoneal macrophages from iNOS−/−mice failed to affect the survival of the rocF mutant. Thus, bacterial arginase allows H. pylori to evade the immune response by down-regulating eukaryotic NO production.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
