Expression of the cytokine IL-11 is elevated in human Helicobacter pylori infection and progressively increases with worsening gastric pathology. Additionally, IL-11 is required for tumour development in STAT3 dependent murine models of gastric cancer (GC) and, when administered acutely, causes resolving atrophic gastritis. However, it is unclear whether locally elevated IL-11 ligand expression can, in isolation from oncogenic gp130-JAK-STAT pathway mutations, initiate GC pathogenesis. Read More

Proton pump inhibitors are commonly utilized for the treatment of gastric acid-related conditions, such as gastroesophageal reflux disease, peptic ulcer disease, and infection, and for the prevention of low-dose aspirin or nonsteroidal anti-inflammatory drug associated peptic ulcers. Vonoprazan is a first-in-class potassium-competitive acid blocker, which has distinct advantages compared to other conventional proton pump inhibitors in terms of the rate and effectiveness at which gastric acid suppression occurs. Due to its strong gastric acid suppression capabilities, vonoprazan serves as an effective drug for the treatment of gastroesophageal reflux disease and infection. Read More

As the number of bacterial genomes and transcriptomes increases, so does the number of newly identified toxin-antitoxin (TA) systems. However, their functional characterization remains challenging, often requiring the use of overexpression vectors that can lead to misinterpretations of in vivo results.

Chronic inflammation of the gastric mucosa, often caused by autoimmune gastritis and/or infection with Helicobacter pylori, can lead to atrophy of acid-secreting parietal cells with metaplasia of remaining cells. The histological pattern marks a critical step in the progression from chronic gastritis to gastric cancer, yet underlying mechanism(s) of inflammation-induced cell death of gastric epithelial cells are poorly understood. We investigated direct effects of a type 1 cytokine associated with autoimmunity and infection, interferon-γ (IFN-γ), on gastric epithelial cells. Read More
