Special Issue "Helicobacter pylori Infection–Inducement of Gastroenteric Diseases"
Deadline for manuscript submissions: closed (31 August 2019).
Interests: bacterial protein toxins; host-pathogen interactions in gastrointestinal tract; helicobacter pylori; infection and gastrointestinal cancer
For almost a century, gastric acid has been considered the most significant offensive factor for the human stomach, a sort of an “enemy inside”. Karl Schwarz’s aphorism of 1910, “no acid, no ulcer”, became a paradigm that paved the way to all the therapeutic approaches to gastritis and peptic ulcers until the early 1980s, when people were obliged to discard all the existing gastroenterology textbooks. This was because Helicobacter pylori was discovered and its pivotal relevance in the most severe gastric diseases rapidly demonstrated: a true revolution in the field.
H. pylori colonizes the stomach of about half the global population, making it one of the most common bacterial infections worldwide. If untreated, the infection becomes chronic and persists throughout life despite a vigorous immune response. H. pylori infection always causes active chronic gastritis that can remain clinically silent for many years after initial infection, due to the dynamic equilibrium between the bacterium and its human host. H. pylori infection may however evolve into more severe diseases, such as atrophic gastritis, peptic ulcer, mucosa-associated lymphoid tissue (MALT) lymphoma, or gastric adenocarcinoma. H. pylori infection is the strongest known risk factor for gastric malignancy and its relevance for gastric cancer development is quite similar to that of tobacco smoking for lung cancer.
H. pylori-induced pathology is the result of a well-choreographed interaction between the pathogen and its host, which is in turn dependent on specific bacterial virulence factors/products (e.g., VacA vacuolating toxin, CagA, HtrA, γ-glutamyl transpeptidase), host genotypic traits and permissive environmental factors.
This Special Issue is aimed at gathering the most recent cutting-edge research on H. pylori strategies and tools to circumvent the defensive capabilities of the host, subverting normal cell function in directions favourable for the bacterium even though, unfortunately, it has a high pathogenic potential for the human host. Both reviews and original papers from clinical and experimental scientists are welcome.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a double-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Toxins is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
