The intestinal epithelial barrier is not just a static physical barrier but rather interacts continuously with the gut microbiome and immune cells. An intact intestinal barrier protects the host against invasion of microorganisms and toxins whereas at the same time it allows absorption of essential fluids and nutrients. The pathophysiology of cirrhosis is associated with a dysfunctional intestinal barrier, which…

Oriol Juanola is a PhD. student of the Hepatic and Intestinal Immunobiology Group at Miguel Hernández University (Alicante, Spain). The group is interested in molecular and cellular aspects around the immune system that are responsible for the surveillance, response and regulation of homeostasis with our gut microbiota in the so-called "gut-liver axis", a central element in different metabolic pathologies within the scope of the gastroenterology and hepatology. The translation of these aspects, addressed from different methodological perspectives, to the clinical field is also relevant for the Group in order to improve the diagnosis, treatment and/or prognosis of these diseases. Rubén Francés is professor of Immunology and Head of the Hepatic and Intestinal Immunobiology Group at Miguel Hernández University and the Biomedical Research Networking Center in Hepatic and Digestive Diseases (CIBEREHD).

Studies exploring the neonatal microbiome during early life have been performed mainly in the hospital setting, with both mode of delivery and antibiotics having the most profound impact on the microbiome. However, the development of the neonatal microbiome in the absence of routine hospital interventions during delivery has not yet been studied. A new study, led by Prof. Maria Gloria…

The use of antibiotics has long been related to a perturbation of the composition and functions of commensal bacterial communities. Some bacteria die in response to antibiotics while gut microbes that harbor antibiotic resistance genes survive. However, little is known regarding the impact of antibiotics on the eradication and recovery of gut microorganisms. A new study, led by Prof. Oluf…

Western diets high in fats and sugars, modern lifestyles with stress and sedentarism and the indiscriminate use of antibiotics together with other frequently prescribed drugs -such as non-steroidal anti-inflammatory drugs and proton pump inhibitors- are major drivers of changes in microbiota composition and gut barrier disruption.

The gut microbiota has wide-ranging effects on host physiology and is an important determinant of health and disease. As we have learned over the past two decades, these effects are not limited to the gastrointestinal tract, but can influence host functions throughout the body.  A great deal of research has focused on understanding the mechanisms by which microbes influence host…

Heather Galipeau is a Research Associate at McMaster University (Canada) where she is researching dietary and microbial interactions in celiac disease and inflammatory bowel disease. She obtained her PhD in 2015 from McMaster University in Elena Verdu’s lab, during which she found that the small intestinal microbial background influences the degree of immuno-pathology triggered by dietary antigens, such as gluten.

The current antibiotic resistance epidemic is reaching levels higher than previously reported. And the roots of this epidemic can be found not only in an increase in outpatient antibiotic use, but also on the high proportions of resistant bacteria transmitted from food-producing animals. The effects of antibiotics on human gut bacterial diversity is of particular relevance during early life. It…

Other than gut microbiota's well-known functions, which include nutrient metabolism and absorption, xenobiotic and drug metabolism, and immune development, its role in protecting against pathogens has been poorly characterized. Previous research has identified some microbiota-mediated colonization resistance mechanisms, while little is known about whether microbial metabolites may also limit pathogen colonization. A new study, led by Dr. Denise Monack from…

This post is a shortened version of the original article published in Science Trends on July 11, 2018. If – for whatever reason – a single toxic bacterial species – Clostridium difficile (C-diff) – has taken over your entire gut ecosystem, has banished many of the commensal gut bacteria needed for a healthy life, and does not respond any longer…

The administration of broad-spectrum antibiotics is an important risk factor for Clostridium difficile infection (CDI) in the Western world. Recent research has suggested that probiotics may help reduce the incidence of C. difficile-associated diarrhea (CDAD) among children and adults in both hospital and outpatient settings. A new systematic review and meta-analysis, led by Dr. Bradley Johnston from Dealhousie University (Canada),…

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…
