Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) is an ongoing or chronic health problem that causes inflammation and swelling in the digestive tract. The irritation causes bleeding sores called ulcers to form along the digestive tract. This in turn can cause crampy, abdominal pain and severe bloody diarrhea.

What is Ulcerative Colitis?

Ulcerative colitis is a chronic condition that affects the large intestines, particularly the colon. It is classified as one of the two inflammatory bowel diseases along with Crohn’s disease.

Specialized immune cells bridge the nervous and immune systems

A collaborative team led by Professor Jie Zhou at Tianjin Medical University School of Basic Medicine and Professor Qiang Liu at Tianjin Medical University General Hospital published a comprehensive review in Volume 2 of the journal Immunity & Inflammation on September 8, 2026.

Dietary changes can prevent Hirschsprung disease symptoms

A multi-institutional study led by researchers at Children's Hospital of Philadelphia (CHOP) discovered for the first time that dietary interventions might prevent inflammatory symptoms associated with Hirschsprung disease, a bowel motility disorder.

Garvan research reveals hidden inflammation behind high colon cancer risk

New research from the Garvan Institute of Medical Research has revealed for the first time that two closely related bowel diseases, currently treated in the same way, are fundamentally different.

New funding supports LMU research on pediatric inflammatory bowel disease

The non-profit Boehringer Ingelheim Stiftung supports LMU clinician-scientist Daniel Kotlarz through its Rise up! program.

Gut infection leaves long-lasting immune ‘memories’ at the brain’s borders in mice

In mice, intestinal infections reshaped dural CD4+ T-cell populations and seeded the brain’s outer meningeal border with antigen-specific memory cells that persisted for months and mounted rapid recall responses to bloodborne antigens. Oral priming was associated with reduced Salmonella spread to the brain and modest cross-protection in an engineered shared-antigen Candida model, although the researchers could not definitively prove that dural CD4+ T cells alone caused the protection.

Gut bacterial metabolite linked to inflammation in liver disease

Researchers have identified a link between specific activities in gut bacteria and the liver disease PSC.

Gut bacterial molecule discovered to drive serious bile duct disease

Researchers at the University of Oslo and Oslo University Hospital have, together with international collaborators, discovered that a small molecule made exclusively by gut bacteria can actively drive disease in the bile ducts and worsen primary sclerosing cholangitis (PSC), a serious liver and bile duct disease.

IBD patients with family cancer history more likely to develop colorectal cancer

People with inflammatory bowel disease (IBD) who have several close relatives with colorectal cancer are significantly more likely to develop the disease themselves.

Cellular atlas offers clues to childhood Crohn’s treatment response

Researchers have created a detailed map of childhood Crohn's disease before and after treatment to help understand progression of the disease.

Antifungal medication may reduce inflammatory bowel disease symptoms

A commonly used systemic antifungal medication may help reduce symptoms in a subset of patients with inflammatory bowel disease (IBD) by restoring a healthier gut microbiome, according to a preliminary study by Weill Cornell Medicine investigators.

Researchers identify early molecular warning signs of inflammatory bowel disease

Researchers have uncovered early molecular warning signs of inflammatory bowel disease, revealing the condition can begin before symptoms appear and continue silently even when patients appear well.

Gut microbiome atlas maps how bacteria establish themselves and shift in inflammatory bowel disease

Researchers created a microbiome-wide atlas mapping more than seven million colonization factor genes across 4,716 human gut microbial species, revealing three putative strategies linked to metabolism, stress resistance, and microbial communication. Applying the framework to inflammatory bowel disease showed that colonization-factor profiles can provide a compact, biologically interpretable view of disease-associated microbiome changes.

Scientists found a distinct gut microbiome pattern in people with symptomatic diverticular disease

A multicenter Japanese study found that symptomatic uncomplicated diverticular disease (SUDD) was associated with reduced gut microbial diversity, increased abundance of the Ruminococcus gnavus group, and depletion of Coprococcus and other butyrate-producing bacteria. Predictive microbiome analysis also identified enrichment of pathways linked to exopolysaccharide biosynthesis and the cell cycle, although the observational design means these associations cannot establish causality.

Emergency diagnoses of medical conditions predict worse patient survival

Patients diagnosed with conditions after an emergency hospital admission or an emergency room visit face a higher risk of death than those diagnosed in non-emergency settings, according to a large population-based study by Emma Whitfield and colleagues from University College London, UK, published August 25th in the open access journal PLOS Medicine.

Scientists compared 51 longevity studies to see which aging biomarkers respond most reliably

Researchers analyzing 51 longitudinal intervention studies found that reliable generation 2+ DNA methylation biomarkers, particularly those predicting mortality or pace of aging, were the most responsive to interventions aimed at longevity or healthspan. Pharmacological and lifestyle interventions produced the strongest biomarker changes, but the authors cautioned that responsiveness does not yet establish these measures as validated surrogate endpoints for slower aging or longer life.
