Beyond oxidative stress: an immunologist’s guide to reactive oxygen species
TL;DR: ROS chemistry and their pleiotropy make them difficult to localize, to quantify and to manipulate — challenges the authors must overcome to translate ROS biology into medical advances.
Journal ArticleDOI

TL;DR: A radial gradient of microbes linked to the distribution of oxygen and nutrients provided by host tissue is observed in an analysis of intestinal microbiota of mice and human beings.

TL;DR: This work presents AGORA (assembly of gut organisms through reconstruction and analysis), a resource of genome-scale metabolic reconstructions semi-automatically generated for 773 human gut bacteria, and identified a defined growth medium for Bacteroides caccae ATCC 34185.

TL;DR: Salmonella virulence factors and antibiotic treatment promote pathogen expansion through the same mechanism: depletion of butyrate-producing Clostridia to elevate epithelial oxygenation, allowing aerobic Salmonella growth.

TL;DR: The ability of HuMiX to recapitulate in vivo transcriptional, metabolic and immunological responses in human intestinal epithelial cells following their co-culture with the commensal Lactobacillus rhamnosus GG (LGG) grown under anaerobic conditions is demonstrated.

TL;DR: The Illumina-based metagenomic sequencing, assembly and characterization of 3.3 million non-redundant microbial genes, derived from 576.7 gigabases of sequence, from faecal samples of 124 European individuals are described, indicating that the entire cohort harbours between 1,000 and 1,150 prevalent bacterial species and each individual at least 160 such species.

TL;DR: Three robust clusters (referred to as enterotypes hereafter) are identified that are not nation or continent specific and confirmed in two published, larger cohorts, indicating that intestinal microbiota variation is generally stratified, not continuous.
