Researchers Need to Look at the Metabolome to Understand the Dynamic Relationship between the Microbiome and the Human Body.
Right now, as you read this article, you are under alien surveillance. If you lower these pages or raise your eyes from the computer screen, you may think you see your co-worker or life partner across the room, but none of these people are who they present themselves to be, or at least not fully.
“Hell, no,” Richard Isaacson bellows when asked whether some form of cognitive decline is inevitable with age, especially for those genetically tilted toward the disabling dementia of Alzheimer’s disease. Then, in the interest of science, an enterprise customarily cloaked in the conjectural, he restrains himself.
An international team of researchers from Spain and the UK has found that the protein TLR2 (Toll-like receptor 2) — a critical detector of the microbiota found in the intestine — regulates levels of serotonin, a neurotransmitter intimately connected to the brain’s regulation of appetite, sleep, and mood.
If you’re making resolutions for a healthier new year, consider a gut makeover. Refashioning the community of bacteria and other microbes living in your intestinal tract, collectively known as the gut microbiome, could be a good long-term investment in your health.
According to a study published in the journal Frontiers in Physiology, extra vitamin D can restore good bacteria in the gut, giving hope in the fight against risk factors for diabetes and heart disease.
Obesity-associated microbiome composition can persist after weight loss, affecting the exchange of metabolites between a mouse and its resident bugs, researchers report.
Researchers are beginning to decipher the metabolic language of the microbiome, and determine how gut microbes communicate with host tissue. Shortly after we finish a good meal, our resident microbes spring into action. The bacteria, viruses, and fungi that inhabit our guts send out metabolites that prepare our organs for the incoming nutrients.

Abstract Calypso is an easy-to-use online software suite that allows non-expert users to mine, interpret and compare taxonomic information from metagenomic or 16S rDNA datasets.
NHGRI Image Gallery The NHGRI Image Gallery provides imagery related to the genomics research, people, and programs of the institute.
Sounds of Science Podcast: A new study from investigators at The Ohio State University
For a detailed look at the state of the microbiome and its role in precision medicine, The Scientist is bringing together a panel of experts to share their research and discuss the next steps. FREE Webinar
Professor Sarkis Mazmanian explains how he and postdoctoral scholar Tim Sampson discovered the link between the gut biome and Parkinson’s disease.
Gathered here…a reflection on the reading most worth prioritizing in the year being left behind. “I have observed many tiny animals with great admiration,” Galileo marveled as he peered through his microscope
We’ve created a fascinating biomedical animation, The Hungry Microbiome, to bring to life years of scientific research and educate the public on how starch gets broken down in the gut.
Anthony L. Komaroff, MD, Brigham and Women’s Hospital, Harvard Medical School, Boston, Massachusetts, shares his viewpoint in JAMA. Published online December 22, 2016: Obesity and type 2 diabetes mellitus are influenced both by genes and lifestyle. That is not news. However, the genes in the human microbiome also may play an important role, and that […]
The second keynote presentation at Arrowhead Publishers’ 3rd Annual Translational Microbiome Conference will be given by Dr. Rita Colwell, Distinguished Professor at Johns Hopkins Bloomberg School of Public Health and founder of CosmosID.
Abstract Different housing systems can be used in pig production and little is known about their effect on gut microbiota composition. In this study we characterized fecal microbiota by sequencing the rRNA genes in sows kept during gestation in conventional pens with a slatted floor and in enriched pens with a floor covered with deep […]
ABSTRACT Background Accumulating evidence indicates interactions between human milk composition, particularly sugars (human milk oligosaccharides or HMO), the gut microbiota of human infants, and behavioral effects.
Abstract BACKGROUND: Diabetes, obesity, and the metabolic syndrome are multifactorial diseases dependent on a complex interaction of host genetics, diet, and other environmental factors.
Highlights •Dietary practices can alter bacterial diversity in the human gut microbiota •Microbiota responses to diets vary in strength across individuals •Promoting bacterial dispersal between host microbiota enhances responses to diets •Metacommunity dynamics have implications for effective nutritional interventions
Abstract Metabolic syndrome (MetS), characterized as obesity, insulin resistance, and non-alcoholic fatty liver diseases (NAFLD), is associated with vitamin D insufficiency/deficiency in epidemiological studies, while the underlying mechanism is poorly addressed. On the other hand, disorder of gut microbiota, namely dysbiosis, is known to cause MetS and NAFLD.
Abstract Astrocytes have important roles in the central nervous system (CNS) during health and disease. Through genome-wide analyses we detected a transcriptional response to type I interferons (IFN-Is) in astrocytes during experimental CNS autoimmunity and also in CNS lesions from patients with multiple sclerosis (MS).
