Limitations of Feces as Proxy for Gut Microbiota

A myriad of factors can influence the gut microbiota composition of laboratory rats and mice: diet, stress, circadian rhythm, vendor source, how they are housed, and more. Since different gut microbiota compositions can elicit different phenotypes under otherwise similar experimental conditions, understanding what shapes the rodent microbiome is becoming increasingly important for researchers. Husbandry-Induced Microbiome […]

Feed Your Gut Microbiota for Improved Health

Clostridium difficile is a significant source of infectious disease death in the United States, and C. difficile infection can be difficult to treat. Many researchers are focusing on new therapies for this major health problem, including clinical use of fecal microbiota transplantation. Dietary manipulations are another avenue of study. Researchers at the Stanford University School […]

A wide-ranging text synthesizes what we know (and don’t know) about the microbiome

Angela Douglas is an internationally recognized expert on symbiosis, with a number of foundational texts to her name (1, 2). In her new book, Fundamentals of Microbiome Science, Douglas synthetizes data from the burgeoning field of microbiome science in eight highly informative chapters. Topics include the origins of the animal microbiome, what we know about […]

Gordon receives British Royal Society’s highest honor

Jeffrey I. Gordon, MD, of Washington University School of Medicine in St. Louis, has received the 2018 Copley Medal from the Royal Society in Britain. He is being honored for his studies of human gut microbial communities, which have led to a fundamental shift in the way scientists understand the relationship between microbes, health and […]

Microbiomania: what we actually know about the human microbiome

Lance Armstrong may not have tried it, but poo doping is the new item of discussion on the performance enhancement menu. It turns out elite cyclists have a couple of critters in their gut that might boost performance. The discovery began three years ago, when Lauren Petersen, a researcher at The Jackson Laboratory for Genomic […]

The Gut Microbiome: Markers of Human Health, Drug Efficacy and Xenobiotic Toxicity

The gut microbiome is believed to play an important role in human health in areas as diverse as brain function and the immune system. Exploring host-microbiome interactions will provide a mechanistic understanding and enable new insights in human diseases (i.e., their diagnosis, prognosis and treatment) and new perceptions of xenobiotic efficacy and/or toxicity. This workshop […]

Diets High in Salt May Increase Sensitivity to Autoimmune Disease through Microbiome Alteration

High salt diets have previously been shown to increase severity of certain types of induced autoimmune disease in mouse models via a signaling pathway, but the impact of these diets on the gut microbiome and intestinal inflammation have not been studied. Researchers at McMaster University recently investigated this question in a paper titled “High salt […]

New Resource for Gnotobiotics Research

Growth in Gnotobiotics Research in gnotobiotic rodents and other animal models is a growing field. The rise in microbiome studies is likely responsible for this increase. This gnotobiotic renaissance has fueled exponential growth in the number of institutions operating or making plans for gnotobiotic facilities and a demand for more education.

Interagency Strategic Plan for Microbiome Research

About this Document This plan was developed by the Microbiome Interagency Working Group (MIWG), an interagency working group under the Life Sciences Subcommittee (LSSC) of the National Science and Technology Council (NSTC) Committee on Science (CoS). The MIWG is a successor to the Fast Track Action Committee on Mapping the Microbiome (FTAC-MM). About the Fast […]

Commensal Microbes May Initiate and Drive Immune Responses in Lupus

Spontaneous lupus erythematosus (SLE) is a chronic autoimmune disease with an unclear cause. Nearly all lupus patients have high levels of anti-nuclear antibodies with a relatively high proportion being pathogenic anti-Ro protein antibodies. At the end of March, researchers at Yale University published a paper entitled “Commensal orthologs of the human autoantigen Ro60 as triggers […]

Nutrition Track Agenda Announced for 4th Annual Translational Microbiome Conference

MINNEAPOLIS, March 29, 2018– Arrowhead Publishers released a parallel nutrition track agenda for the 4th Annual Translational Microbiome Conference, scheduled April 18-20 in Boston. The conference is designed to bring together scientists at the forefront of microbiome research with pioneering business leaders at companies generating microbiome-based medical solutions. Sponsored by Nestlé Health Science, the nutrition […]

Squeaky clean mice could be ruining research

Most lab mice are kept in pristine conditions, but a few immunologists think a dose of dirt could make them a better model of human disease. On an unseasonably warm February morning, Mark Pierson takes a 20-minute drive to one of Minneapolis’s larger pet shops. Pierson, a researcher in an immunology laboratory at the University […]

Gender-Dependent Impacts of Round-Up Herbicide on Microbiome

It is heavily debated whether the use of the weedkiller glyphosate in agriculture and gardening can induce dysbiosis of the gut microbiota, negatively affecting human and animal health. Dysbiosis is an imbalance in the microbiome composition associated with conditions such as colitis, metabolic syndrome, allergies, and more. Herbicide and the Microbiome We recently highlighted new […]

Which experimental systems should we use for human microbiome science?

ABSTRACT Microbiome science is revealing that the phenotype and health of animals, including humans, depend on the sustained function of their resident microorganisms. In this essay, I argue for thoughtful choice of model systems for human microbiome science. A greater variety of experimental systems, including wider use of invertebrate models, would benefit biomedical research, while […]

Microbiome Cycles Revealed by Low-Cost Gnotobiotic Cages

While developing a low-cost alternative to traditional gnotobiotic isolators, a team of researchers at Case Western Reserve University (CWRU) were able to characterize cyclical changes in the microbiomes of gnotobiotic mice. Their research has implications for both the design and affordability of gnotobiotic animal model research. High Cost of Gnotobiotic Isolators Isolators are the gold […]

The conundrum with animal models of the human microbiome

‘The most that can be expected from any model is that it can supply a useful approximation to reality: All models are wrong; some models are useful.’ This aphorism, simply articulated here by prominent British statistician George Box, gets to the crux of the dilemma we face when considering animal models for the study of […]

The Macro Influence of the Microbiome

I am pleased to draw your attention to this, the first ever topical issue of Brief Reviews in The Journal of Immunology. Through seven Brief Reviews, this issue of The JI highlights the pervasive impact of the gut microbiome on immune functions, both in the gut and at distal sites, and features a cover chosen […]

High-Fiber Diet Shifts Gut Microbes, Lowering Blood Sugar in Diabetics

A diet high in fiber can reshape the gut microbiome, helping people with type 2 diabetes stay healthy. A study published yesterday (March 8) in Science found that when patients with the condition ate a high-fiber diet, they had an abundance of microbial species that helped to reduce blood sugar and regulate weight compared with […]
