Immune adaptations that maintain homeostasis with the intestinal microbiota
TLDR
The unique adaptations of the intestinal immune system that maintain homeostatic interactions with a diverse resident microbiota are discussed.Abstract:
Humans harbour nearly 100 trillion intestinal bacteria that are essential for health. Millions of years of co-evolution have moulded this human-microorganism interaction into a symbiotic relationship in which gut bacteria make essential contributions to human nutrient metabolism and in return occupy a nutrient-rich environment. Although intestinal microorganisms carry out essential functions for their hosts, they pose a constant threat of invasion owing to their sheer numbers and the large intestinal surface area. In this Review, we discuss the unique adaptations of the intestinal immune system that maintain homeostatic interactions with a diverse resident microbiota.read more

Cross-talk between Akkermansia muciniphila and intestinal epithelium controls diet-induced obesity

TL;DR: Substantial insight is provided into the intricate mechanisms of bacterial regulation of the cross-talk between the host and gut microbiota and provides a rationale for the development of a treatment that uses this human mucus colonizer for the prevention or treatment of obesity and its associated metabolic disorders.

Role of the Microbiota in Immunity and Inflammation
Yasmine Belkaid,Timothy W. Hand +1 more
TL;DR: In high-income countries, overuse of antibiotics, changes in diet, and elimination of constitutive partners, such as nematodes, may have selected for a microbiota that lack the resilience and diversity required to establish balanced immune responses.

The gut microbiota — masters of host development and physiology
TL;DR: The gut microbiota has a beneficial role during normal homeostasis, modulating the host's immune system as well as influencing host development and physiology, including organ development and morphogenesis, and host metabolism.
Journal ArticleDOI
The role of the gut microbiota in nutrition and health
TL;DR: The complex interplay between the gut microbiota, diet and health is considered and better definition of those dominant commensal bacteria, community profiles and system characteristics that produce stable gut communities beneficial to health is important.

Introduction to the human gut microbiota
Elizabeth Thursby,Nathalie Juge +1 more
TL;DR: This review summarises the current understanding of the development and composition of the human GI microbiota, and its impact on gut integrity and host health, underlying the need for mechanistic studies focusing on host–microbe interactions.

TL;DR: A majority of the bacterial sequences corresponded to uncultivated species and novel microorganisms, and significant intersubject variability and differences between stool and mucosa community composition were discovered.

TL;DR: It is suggested that the NOD2 gene product confers susceptibility to Crohn's disease by altering the recognition of these components and/or by over-activating NF-kB in monocytes, thus documenting a molecular model for the pathogenic mechanism of Crohn’s disease that can now be further investigated.

A frameshift mutation in NOD2 associated with susceptibility to Crohn's disease

TL;DR: It is shown that a frameshift mutation caused by a cytosine insertion, 3020insC, which is expected to encode a truncated NOD2 protein, is associated with Crohn's disease, and a link between an innate immune response to bacterial components and development of disease is suggested.

Interleukin-10-deficient mice develop chronic enterocolitis
TL;DR: The results indicate that the bowel inflammation in the mutants originates from uncontrolled immune responses stimulated by enteric antigens and that IL-10 is an essential immunoregulator in the intestinal tract.

Recognition of Commensal Microflora by Toll-Like Receptors Is Required for Intestinal Homeostasis

TL;DR: It is shown that commensal bacteria are recognized by TLRs under normal steady-state conditions, and this interaction plays a crucial role in the maintenance of intestinal epithelial homeostasis and protection from injury.
