Timing is Everything: ISB Study Finds Link Between Bowel Movement Frequency and Overall Health

Everybody poops, but not every day. An ISB-led research team examined the clinical, lifestyle, and multi-omic data of more than 1,400 healthy adults. How often people poop, they found, can have a large influence on one’s physiology and health.

Hack Your Health: An Evening with Anjali Nayar and Dr. Sean Gibbons

Netflix’s “Hack Your Health: The Secrets of Your Gut” is a documentary that merged gut microbiome experts, four individuals – including a well-known hot dog eating champion – facing personal battles with gastrointestinal health, and a unique, effective visual method of “showing” the gut microbiome in action. 

A New Path Toward Microbiome-Informed Precision Nutrition

ISB researchers have developed a novel way to simulate personalized, microbiome-mediated responses to diet. They use a microbial community-scale metabolic modeling (MCMM) approach to predict individual-specific short-chain fatty acid production rates in response to different dietary, prebiotic, and probiotic inputs.

Making Nutrition and Healthcare Personalized, Predictive, and Preventive

Dr. Sean Gibbons is creating a new precision nutrition platform called My Digital Gut that leverages the gut microbiome to make nutrition and healthcare personalized, predictive, and preventive. In an ISB Research Roundtable presentation, Gibbons spoke about My Digital Gut and other microbiome-related projects studied in his lab.   

‘1 in 1,000:’ Dr. Sean Gibbons Named Highly Cited Researcher for 2023

ISB Associate Professor Dr. Sean Gibbons was named a Highly Cited Researcher for 2023. It is the second consecutive year Gibbons has earned the distinction. The Highly Cited Research list is generated annually by Clarivate, which says: “Of the world’s population of scientists and social scientists, Highly Cited Researchers are 1 in 1,000.”

Dr. Sean Gibbons Promoted to Associate Professor

Dr. Sean Gibbons – an expert in microbial ecology and evolution, computational systems biology, the human gut microbiome and its impacts on health, and head of ISB’s Gibbons Lab – has been promoted to Associate Professor. “Sean’s achievements since joining ISB in 2018 as a Washington Research Foundation Distinguished Investigator have been spectacular,” ISB President Dr. Jim Heath said. “With his focus on the microbiome, he brought a whole new…

The Gut Microbiome’s Supersized Role In Shaping Our Metabolome

ISB researchers have shown which blood metabolites are associated with the gut microbiome, genetics, or the interplay between both. Their findings, published in the journal Nature Metabolism, have promising implications for guiding targeted therapies designed to alter the composition of the blood metabolome to improve human health.

Bugs vs. Drugs: How Our Microbiomes Can Explain Our Response to Statins

ISB Assistant Professor Dr. Sean Gibbons talked about the science behind statins in our most recent Research Roundtable virtual presentation. His talk was titled “Bugs vs. Drugs: How Our Unique Gut Microbiomes Shape Our Personalized Responses to Statins.”

Gut Microbiome Composition Predictive of Patient Response to Statins

New ISB research shows that different patient responses to statins can be explained by the variation in the human microbiome. The findings were published in the journal Med, and suggest that microbiome monitoring could be used to help optimize personalized statin treatments.

Microbiome and weight loss

Can You Lose Weight? Ask Your Microbiome

The strongest associations with weight loss success or failure – independent of BMI – are found in the genetic capacity of the gut microbiome. These new findings open the door to diagnostic tests that can identify people likely to lose weight with healthy lifestyle changes and those who might need more drastic interventions.

Personalized Nutrition and Your Gut Microbiome

In ISB’s first-ever Research Roundtable event, Assistant Professor Dr. Sean Gibbons delivered a presentation titled “Gut-Check: Personalized Nutrition and Your Microbiome.” His talk covered a lot of ground, including recently published research showing how the health of our microbiomes can predict longevity, and how we can build and maintain a healthy gut microbiome. 

The Aging Microbiome

Gut Microbiome Implicated in Healthy Aging and Longevity

The gut microbiome is an integral component of the body, but its importance in the human aging process is unclear. ISB researchers and their collaborators have identified distinct signatures in the gut microbiome that are associated with either healthy or unhealthy aging trajectories, which in turn predict survival in a population of older individuals.

Overall composition of gut microbiome in participants

Variations in the Microbiome Associated with Health, Disease

ISB researchers examined the associations between the gut microbiomes of about 3,400 people and roughly 150 host characteristics. The team looked at diet, medication use, clinical blood markers, and other lifestyle and clinical factors, and found evidence that variations of the gut microbiome are associated with health and disease.

Bacterial tug of war between prevotella and bacteroides -- gut microbiome

It’s ‘Either/Or’ for Two Common Gut Microbiome Genera, and Switching Teams Is Tougher Than Expected

There is a dichotomy between Bacteroides- and Prevotella-dominated guts — two common gut bacterial genera — and there is a significant barrier when it comes to transitioning from one to the other.

New Modeling Tool Allows Microbiome Researchers to Map Community Ecology to Ecosystem Function

A promising new open-source metabolic modeling tool provides microbiome researchers a path forward in predicting ecosystem function from community structure. News of the software package, called MICOM, was developed in part by researchers in ISB’s Gibbons Lab, and its uses were published in the journal mSystems.

Using Blood to Predict Gut Microbiome Diversity

Predicting the alpha diversity of an individual’s gut microbiome is possible by examining metabolites in the blood. The robust relationship between host metabolome and gut microbiome diversity opens the door for a fast, cheap and reliable blood test to identify individuals with low gut diversity.

All About the Human Microbiome

The human microbiome is a relatively new area of research, and there are numerous questions surrounding it. What is the human microbiome? Can we change it? Does it make us sick? Keep us well? ISB Assistant Professor and microbiome researcher Dr. Sean Gibbons answers these questions — and many more.

ISB's Dr. Sean Gibbons on the importance of the human microbiome

“This new organ that we’re coming to recognize as the microbiome is part and parcel to the functionality of the whole system, and if it breaks down, if it starts to fall apart, we start to get sick,” said Dr. Sean Gibbons, ISB’s newest faculty member, in a WGBH Forum Network presentation.
