Paneth cells, antimicrobial peptides and maintenance of intestinal homeostasis
TLDR
An overview of the intestinal microbiota is provided and the cell biology of Paneth cells is described, emphasizing the composition of their secretions and the roles of these cells in intestinal host defence and homeostasis.Abstract:
Building and maintaining a homeostatic relationship between a host and its colonizing microbiota entails ongoing complex interactions between the host and the microorganisms. The mucosal immune system, including epithelial cells, plays an essential part in negotiating this equilibrium. Paneth cells (specialized cells in the epithelium of the small intestine) are an important source of antimicrobial peptides in the intestine. These cells have become the focus of investigations that explore the mechanisms of host-microorganism homeostasis in the small intestine and its collapse in the processes of infection and chronic inflammation. In this Review, we provide an overview of the intestinal microbiota and describe the cell biology of Paneth cells, emphasizing the composition of their secretions and the roles of these cells in intestinal host defence and homeostasis. We also highlight the implications of Paneth cell dysfunction in susceptibility to chronic inflammatory bowel disease.read more

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.

Gut biogeography of the bacterial microbiota
TL;DR: Novel hypotheses for how nutrient selection, immune activation and other mechanisms control the biogeography of bacteria in the gut are considered, and the relevance of this spatial heterogeneity to health and disease is discussed.

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.
