Research

The microbiota impacts all aspects of human health, including the immune system, metabolism, and neurological health. Microbiome research is an area of exponential growth. Discovery efforts on the microbiome have the potential to reshape treatment paradigms in human disease.

MAGIC aims to catalyze discoveries in this area to realize this vision.

Inflammatory Bowel Disease (IBD)

Inflammatory bowel Diseases (IBD), such as Crohn’s disease and Ulcerative colitis, has been steadily rising in incidence all over the world. In fact, 1 in 123 people will be diagnosed with IBD and this poses a tremendous burden on the health care system as there currently is no cure and many of the therapies are quite expensive.  More importantly, individuals with IBD are in constant pain, more likely to develop colon cancer, and this disease has a serious burden on their quality of life, social interactions and ability to work. Despite the advancements in therapies for IBD over the last decade, many patients quickly become unresponsive to treatment.  Thus, understanding the underlying causes of these diseases will allow for the better therapeutics and preventative strategies.

 While the cause of IBD remains unknown it seems clear that microbiota composition is a critical aspect of its development. Research at the University of Utah has discovered microbes and immune pathways that help prevent this disease in animal models. Collaborations across the MAGIC center will help to move these critical discoveries to the benchside.

Intestinal Infections

Daniel Leung, Matt Mulvey, Jackie Winter, Nicole Pershing, Andrew Skinner

Virtually all pathogenic agents must cross a mucosal barrier to infect their host. Mucosal sites, such as the mouth, the lung and the GI tract, are also home to the trillions of the microbes that reside on the human body. Thus, the interactions between these commensal microbes and the immune system at mucosal sites are instrumental in combating and preventing infectious agents.

Additionally, under specific circumstances, commensal microbes can cause problems. The researchers at the University of Utah are studying mechanisms by which gut bacteria can prevent pathogenic organisms, such as COVID-19, from causing severe disease and uncover the unique immune pathways that fend off harmful microbes.

Most of the microbes that reside on our body live in the gastrointestinal tract and, not surprisingly, have been shown to influence cancer development. Cancers occur at sites within the GI tract including the liver, pancreas, gall bladder, small intestine and colon. Moreover, many of these cancers are increasing in incidence across the globe.  While once thought to be a disease of the old is now rapidly increasing in younger individuals. Thus, understanding mechanisms that initiate and prevent these devastating cancers can have a large impact on the global population. Microbes have an intimate association with these tissues sites. Metabolites and products from the microbiota can directly interact with these GI tissues and therefore impact the development and prevention of these cancers. The MAGIC center aims to connect clinicians and scientists in this area to identify novel immune pathways and microbial molecules to treat and prevent this disease.

Eosinophilic Gastrointestinal Diseases

Kathryn Peterson, MD, Amiko Uchida, MD

Eosinophilic gastrointestinal diseases (EGIDs) are chronic allergic inflammatory diseases of the GI tract that are increasingly common and have few to no therapies. Researchers at the University of Utah are working to understand how environmental factors like diet and the microbiota impact human health in the setting of EGIDs.   

Metabolic Disease

Obesity and diabetes are becoming a worldwide epidemic.  While dietary interventions are known to improve these diseases, these interventions do not always work. What we consume or what medications we take can influence the communities of bacteria within our gut. Understanding how these microbes and nutrition influence the development of diabetes and obesity can identify novel strategies for treatment.  Research at the University of Utah has uncovered gut microbes that can prevent obesity, nutritional supplements that improve metabolic health, immune pathways that elicit diabetes, and gut microbial molecules that might temper development of diabetes. Collaborations fostered through the MAGIC center will help identify other important interactions between the immune system and microbes that could help address this growing global problem.

Neurological disease 

Matt Mulvey, Bia Silva

Many individuals with neurological disorders have co-occurring gastro-intestinal symptoms. This includes diseases such as autism, multiple sclerosis, Parkinson’s diseases and even stroke patients. This clinical observation has led to the notion that many of these neurological disorders have connections to gut health. Supporting this, there is now data to demonstrate that the commensal microbes that reside within the gut can influence the severity of many of these diseases. Moreover, immune cells that reside within the intestine are capable of trafficking to the central nervous system (CNS) to prevent or exacerbate disease. This highlights that gastrointestinal health is an instrumental aspect of neurological health. Researchers at the University of Utah are discovering that microbes in the gut can prevent infection of the CNS, are involved in stroke and can influence behavior.  This area of study covers expertise in neurology, immunology, microbiology and beyond. Thus, interactions across scientific disciplines and departments within MAGIC is instrumental in making advancements in these fields.
