Activating the right immune cells in infants could lead to new vaccine In a paper that suggests a new strategy to prevent asthma, scientists at Children's Hospital Boston and their colleagues report that the influenza virus infection in young mice protected the mice as adults against the development of allergic asthma. The same protective effect was achieved by treating young mice with compound isolated from the bacterium Helicobacter pylori (H. pylori), a bacterium that colonizes the stomach...

YANG Nan, MAO ZongWan and SUN HongZhe et al., at the Department of Chemistry, University of Hong Kong and Sun Yat-sen University have characterized a series of bismuth citrate complexes by X-ray crystallography and modeled the structure of ranitidine bismuth citrate, a medicine used widely for the treatment of peptic ulcer and gastric reflux disease. The polymeric framework of bismuth citrate may serve as a "drug carrier" for delivery of other drugs in the human body. This significant...

Helicobacter pylori in the mouse stomach put the brakes on colitis by reducing the immune response in the lower GI tract, U-M study shows Helicobacter pylori, a common stomach bacterium, reduced the severity of inflammation of the colon caused by Salmonella in mice, according to research from U-M Medical School scientists. More than half the people in the world are infected with H. pylori, although it is very unusual to find it in the United States. But this research shows there may be an...

Researchers have discovered a mechanism by which Helicobacter pylori, the only known cancer-causing bacterium, disables a tumor suppressor protein in host cells. The new study, in the journal Oncogene, reports the discovery of a previously unknown mechanism linking H. pylori infection and stomach cancer, the second leading cause of cancer deaths worldwide. About two-thirds of the world's population is infected with H. pylori, a bacterium that can survive in the harsh environment of the...

Researchers have identified cells in the immune system that react to the stomach ulcer bacterium Helicobacter pylori, one of the risk factors for the development of stomach cancer. This discovery could lead to faster diagnosis and treatment as well as a better prognosis for patients with stomach cancer, reveals a thesis from the University of Gothenburg, Sweden. Helicobacter pylori is one of the most common bacterial infections in the world, and leads to chronic inflammation of the stomach....

An international team of researchers led by scientists at the Virginia Bioinformatics Institute (VBI) at Virginia Tech have sequenced the genome of an Amerindian strain of the gastric bug Helicobacter pylori, confirming the out-of-Africa migration of this bacterial stowaway to the New World. Experiments in animals have highlighted how specific genes in the bacterial strain may be crucial to the onset of inflammation and disease. H. pylori is a bacterium that colonizes the stomachs of over...

SEATTLE, May 28 /PRNewswire/ -- The bacterium Helicobacter pylori, which lives in the human stomach and is associated with ulcers and gastric cancer, is shaped like a corkscrew, or helix. For years researchers have hypothesized that the bacterium's twisty shape is what enables it to survive - and thrive - within the stomach's acid-drenched environment, but until now they have had no proof. For the first time, researchers at Fred Hutchinson Cancer Research Center have found that, at least...

Helicobacter pylori is a Gram-negative, microaerophilic bacterium that can inhabit various areas of the stomach, particularly the antrum. It causes low-level inflammation of the stomach lining and is linked to gastric ulcers and stomach cancer. Out of those infected, 80%, are asymptomatic. It was initially named Campyloacter pyloridis and then renamed C. pylori to correct the Latin grammar error. It was later placed in the genus, Helicobacter. Over 50% of the population has H. pylori in...
