Gilbert C FAURE's insight:
Abstract

Helicobacter pylori (H. pylori) -induced gastric inflammation impacts the functions of leptin- and ghrelin-producing cells in the gastroduodenum. Inflammation resulting from H. pylori sensing via Toll-like receptors (TLRs) and the associated downstream signaling largely remain ambiguous. Here, we investigated the role of gut hormones, pro-inflammatory cytokines and single nucleotide polymorphisms (SNPs) associated with TLR 4p14 in H. pylori disease in 30 subjects with non-ulcer dyspepsia (NUD), 40 with peptic ulcer disease (PUD) and 15 with gastric cancer (GC) subjects positive and negative for H. pylori infection. The level of pro-inflammatory cytokines was directly proportional to the severity of gastritis, and disease status influenced the levels of gut hormones and pro-inflammatory cytokines. TLR-1 SNPs rs4833095 and TLR-10 SNPs rs10004195 and were directly associated with H. pylori disease, and were up-regulated in the presence of H. pylori in a genotype-independent manner. We concluded that TLR-1 rs4833095 and TLR10 rs10004195 confer susceptibility to development of gastroduodenal disease, especially GC in H.pylori disease.

Scientists appeal for ambitious microbiome study

Scientists appeal for ambitious microbiome study | Mucosal Immunity | Scoop.it
A group of 48 scientists from 50 US institutions Wednesday called for more ambitious research into the tiny microorganisms that play a huge role in health, energy and farming.
Known as the Unified Microbiome Initiative Consortium (UMIC), the effort aims to vastly improve research on microbiomes, whether they be in the soil, the water or the human gut.
The project would uncover the role of individual microbes—which include fungi, bacteria, viruses, algae and more—and how they communicate with each other, their hosts, and their environment.
The US-based program would have a 10-year timeframe, and could be complemented by a European effort, scientists wrote in the journals Science and Nature.
"Over the past 20 years, new technologies have reshaped our understanding of the essential roles microbes play on our planet," said a statement by Miyoung Chun, executive vice president of science programs at The Kavli Foundation.
"A Unified Microbiome Initiative would develop the transformative tools and research teams we need to harness the power of these communities to improve human health, agricultural productivity, bioenergy production, and environmental stability."
There are believed to be 100 trillion microbes in the human gut, and they are critical to health and development, but scientists are only just beginning to understand why.
Those calling for the new effort hail from the Department of Energy, national laboratories, universities and research institutions.

IBD genetically similar in Europeans and non-Europeans - Wellcome Trust Sanger Institute

IBD genetically similar in Europeans and non-Europeans - Wellcome Trust Sanger Institute | Mucosal Immunity | Scoop.it
Gilbert C FAURE's insight:

By including 10,000 non-European samples alongside the existing European samples, the team were able to detect 38 additional regions of the genome that influence susceptibility to IBD. Because the genetic effects were largely consistent across populations, the researchers hypothesized that the reason they were able to discover these new regions was the big increase in sample size, rather than because the additional samples were drawn from non-European individuals.
