Helicobacter pylori and Extragastric Diseases


Kyburz, Andreas; Müller, Anne (2017). Helicobacter pylori and Extragastric Diseases. In: Tegtmeyer, Nicole; Backert, Steffen. Molecular Pathogenesis and Signal Transduction by Helicobacter pylori. Springer International Publishing: Springer, 325-347.

Abstract

The Gram-negative bacterium Helicobacter pylori is predominantly known for its tight association with peptic ulcer disease and gastric cancer development. However, recent epidemiological and experimental evidence suggests that chronic infection with H. pylori may at the same time be beneficial to the host by conferring protection against gastroesophageal diseases, asthma, other allergic disease manifestations and inflammatory bowel diseases (IBD). In this chapter, we summarize the epidemiological data that are available to date to support or refute a possible inverse correlation of H. pylori infection with various extragastric diseases. We further examine and discuss the experimental evidence, generated mostly in mouse models of allergic diseases and IBD, showing that these disorders fail to develop in the presence of H. pylori. The proposed mechanisms of the protective effects of H. pylori, which appear to involve the induction of regulatory T-cells (Tregs) with highly suppressive activity, are presented and explained.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
