Individual Candida albicans yeast strains in the human gut are as different from each other as the humans that carry them, and some C. albicans strains may damage the gut of patients with inflammatory bowel disease (IBD), according to a new study from researchers at Weill Cornell Medicine. The findings suggest a possible way to tailor treatments to individual patients in the future.

The researchers, who report their findings March 16 in Nature, used an array of techniques to study strains, or genetic variants, of Candida f...

Microplastics — tiny pieces of plastic less than 5 mm in length — are everywhere, from bottled water to food to air. According to recent estimates, people consume tens of thousands of these particles each year, with unknown health consequences. Now, researchers reporting in ACS’ Environmental Science & Technology found that people with inflammatory bowel disease (IBD) have more microplastics in their feces than healthy controls, suggesting that the fragments could be related to the disease process.

The prevalence of IBD, which includes ...

Scientists hope that tiny sacs of material excreted by cells — so-called extracellular vesicles — can be used to deliver drugs inside the body. Researchers at Karolinska Institutet now show that these nanobubbles can transport protein drugs that reduce inflammation caused by different diseases. The technique, which is presented in Nature Biomedical Engineering, shows promising results in animal models.

Extracellular vesicles (EVs) are important in inter-cellular communication as carriers of biological signals. They are nanometre-sized membrane-coated packages excreted by cells that can deliver fatty acids, proteins and genetic material to different tissues.

The tiny bubbles are f...

A team of researchers led by a biomedical scientist at the University of California, Riverside, has identified a novel mechanism by which loss-of-function mutations in the gene PTPN2, found in many patients with inflammatory bowel disease, or IBD, affect how intestinal epithelial cells maintain a barrier.

The intestinal epithelium, a single layer of cells, plays a critical role in human health by providing a barrier while also allowing nutrient and water absorption. Intestinal epithelial cells are needed for regulating immune function, communicating with the intestinal microbiota, and protecting the gut from pathogen infection – all of which critically depend on an intact epithelial barrier.

Affecting roughly 3 million Americans, IBD is a set of chronic intestinal diseases in wh...
