One of the strategies used by vertebrate hosts to defend against bacterial pathogens is that of sequestering transition metals required for intracellular and extracellular pathogen survival. This process is called “nutritional immunity” and, in response, bacteria have evolved strategies to access metals and counteract this host mechanism of defense. A new review, led by Dr. Christopher Lopez and Prof. Eric…

The enteric nervous system (ENS) is involved in regulating gastrointestinal tract homeostasis through crosstalk between the brain, the gut microbiota, the endocrine and the immune system. Although in mice the ENS is mostly developed during embryogenesis and early postnatal life, recent research has found that it undergoes a dynamic renewal during adulthood. However, mechanistic studies on gut microbiota's role in…

Previous experimental research has found that metabolomics can be used to monitor the impact of host diet on gut microbiota functionality. These data suggest that focusing on gut microbiota functionality may allow for a better characterization of the gut microbiota and its interaction with the host than only studying its composition. A new study, led by Dr. Tim Spector and…

Mice models are widely used to assess the impact of exposure to environmental factors such as chemicals, drugs or infectious agents on host homeostasis through modulation of the gut microbiota. A new study, led by Dr. Guodong Zhang from the University of Massachusetts (USA), has found that exposure to triclosan increases colonic inflammation and colitis-associated colon tumorigenesis in mice. Triclosan…

Recent research has found an association between colorectal cancer (CRC) and variations in the gut microbiome composition. Although mice research supports the theory that tumor development appears to be driven by interactions between the gut microbiome and host genomics, mechanisms involved in the crosstalk between colorectal carcinogenesis and the gut microbiome are still unknown. A new study, led by Prof.…

Although gut microbiota profiles differ remarkably between healthy individuals, several features have been suggested to define a “healthy gut microbiome”. First of all, our gut microbiota can be understood, in many cases, to be redundant given that many bacterial species have similar functions. Furthermore, a healthy gut microbiome is temporally stable and resistant to perturbations and, over time, is more…

In the absence of profound perturbation, bacterial communities living in the gut are mostly stable over time within an individual and between family members. However, the effect of exogenous dietary factors including both pre- and probiotics is generally variable and depends on individualized features of the background microbiota. In the complexity of gut ecology, understanding which factors drive exogenous strain…

The effects of dietary fiber on a host's innate immune responses are thought to be mediated at local and systemic levels via short-chain fatty acids (SCFAs). Previous preclinical research has shown that mice that consume a diet high in fermentable fiber are protected against allergic airway inflammation through SCFAs. However, underlying mechanisms are poorly understood. A new study, led by…

Secretory immunoglobulin A (IgA) is the most abundant antibody in mucosal secretions and has been recognized as a first line of defense in protecting the intestinal epithelium from enteric pathogens. Despite its important role in mucosal immunity and intestinal homeostasis, IgA deficiency—defined by undetectable seric IgA titers (<0.07 mg/ml) with normal IgG concentration—is related to a very mild phenotype in…

Obesity currently affects up to 650 million people worldwide and this figure has doubled since 1980. Of the environmental factors that may contribute to the development of obesity, gut microbiota is in the spotlight, given that it may be involved in the low-grade inflammatory process and subsequent disrupted glucose metabolism and fat absorption that are features of obesity. Epidemiological research…
