Putting the Brakes on Chronic Inflammation

Scientists at Weill Cornell Medicine have discovered a previously unknown link between two key pathways that regulate the immune system in mammals—a finding that impacts our understanding of chronic inflammatory bowel diseases (IBD). This family of disorders severely impacts the health and quality of life of more than 2 million people in the United States.The immune system has many pathways to protect the body from infection, but sometimes an overactive immune response results in...

Common Type of Fiber May Trigger Bowel Inflammation

Inulin, a type of fiber found in certain plant-based foods and fiber supplements, causes inflammation in the gut and exacerbates inflammatory bowel disease in a preclinical model, according to a new study by Weill Cornell Medicine investigators. The surprising findings could pave the way for therapeutic diets that may help ease symptoms and promote gut health. The study, recently published in the Journal of Experimental Medicine, shows that inulin, which is found in...

New Insight into How an Old IBD Drug Works

In a study recently published in Cell Reports Medicine, a team of researchers lead by senior author Dr. Randy Longman, Director of the Jill Roberts Center for IBD and Associate Professor of Medicine at Weill Cornell Medicine in the Division of Gastroenterology & Hepatology, examined IBD-SpA patients treated with sulfasalazine and found that the presence of the gut bacterium Faecalibacterium prausnitzii was a key factor enabling successful treatment responses. They determined that...

Department of Medicine Researchers Publish Groundbreaking Study on Gut Fungi's Lasting Impact on Severe COVID-19 Immune Response

A new study lead by Weill Department of Medicine and NewYork-Presbyterian investigators finds that certain gut-dwelling fungi flourish in severe cases of COVID-19, amplifying the excessive inflammation that drives the disease while also causing long-term immune system changes. This discovery also identifies a group of patients who may benefit from specialized, but yet-to-be determined treatments.The research reveals a new dimension of the...
