The symbiotic relationship between host and microbes starts early in life and is important not only in terms of how the neonate microbiome ultimately develops, but also its potential impact on long-term infant health. A current ongoing debate within the scientific community is whether gut colonization starts during pregnancy or at birth. Indeed, the crucial question of when bacteria first…

Research Director at the French Research Institute in Agricultural Sciences, INRA, Dr. Joël Doré is currently President of the Executive Committee of the Pre-Industrial Demonstrator MetaGenoPolis, a platform of excellence dedicated to quantitative and functional metagenomics, funded by the French government Futures Investments. He is Deputy Head of the MICALIS institute “Food and Gut Microbiology for Human Health” and scientific board member of Microbiology Pole of the Doctoral School “Therapeutic Innovations” at Paris-XI University. Joël Doré received his PhD from the University of Illinois at Urbana-Champaign, USA, in 1988. His main research interest is the molecular assessment of the human intestinal microbiota in health and disease and metagenomic investigation of the molecular cross-talk between intestinal bacteria and human cells. Dr. Doré has published >120 publications in peer reviewed scientific journals. His goal is to provide a better understanding of the intestinal ecosystem in order to support therapeutic choices in the medical area, as well as health claims for functional foods.

Poor sleep quality is a widespread problem and has been associated with several diseases in humans such as cardiovascular disease and cancer. Previous research has reported that the human gut microbiota may express endogenous circadian rhythms, together with findings showing alterations of the gut microbiota in response to sleep deprivation. On the other hand, the gut microbiota and its metabolites…

Non-alcoholic fatty liver disease (NAFLD) is the main cause of chronic liver disease in developed countries. NAFLD often shares symptoms with other metabolic disorders such as type 2 diabetes and obesity. Recently, our gut microbiota has been revealed as a contributor to fatty liver disease development in both rodent models and NAFLD patients. However, the question of whether gut microbes…

Although the gut microbiome remains relatively stable throughout adulthood, various environmental factors such as disease, and diet have been reported to affect the gut microbiota composition. Although host genotype may influence relative abundance of microbial taxa, only few associations between host genetics and gut microbiota diversity have been found. Thus, inter-individual gut microbiome variation remains largely unexplained. Researchers from different…

Besides bacteria, researchers have begun to study archaea, fungi, protozoa and viruses of the human gut microbiome. Although it is now known that the human gut microbiome contains several viruses, most of which are bacteriaphages, little is known about the human gut virome partly due to limitations in analyzing the fecal virome with the current metagenomic and bioinformatic protocols and…

Macronutrients, micronutrients and non-nutritive compounds are major drivers of the composition and metabolic functions of gut microbial communities. However, nutrient composition alone cannot explain the way people’s gut microbiomes are so different to each other. One feature that distinguishes humans from other species is our ability to heat-treat our meals. This process alters nutrients and makes foods more digestible, while…

The gut microbiome can shape health and the risk of disease, though the molecular mechanisms of these interactions are still unclear. Although host genetics is one of the factors that can shape gut microbiome variation, looking at it from the opposite perspective, it is less clear to what extent the microbiome may affect gene expression. In a new cell culture…

Preterm infants exhibit higher rates of necrotizing enterocolitis (NEC), which is a major cause of both mortality and neurodevelopmental morbidity. Although an altered gut microbiota composition and metabolome has been found in preterm infants, the few studies exploring the microbiome in NEC and preterm infants have reported inconsistent results. Within the mechanisms by which the development of NEC occurs, a…

Emerging evidence shows the involvement of our gut microbiome in conditions apparently unrelated to the gut ecosystem. And it seems that is the case with polycystic ovary syndrome (PCOS), which is a heterogeneous endocrine disorder that is often accompanied by altered insulin activity. Recent studies have associated alterations in gut microbiome composition and barrier function with imbalances in the stool…

The source of variation in the composition and function of the microbiome within and between species is yet to be fully understood. Although genetic background and diet have been suggested as major drivers of gut microbiome composition, the role of genetics versus environmental factors in driving gut microbiome variation in closely related primates remains unclear.
