Intricate Relationship Between Goblet Cells and the Gut Microbiome

In a new study, scientists from the University of California, San Diego have shed light on the crucial function goblet cells—specialized gut-lining cells—play in preserving a balanced and healthy immune environment in the gastrointestinal (GI) tract. Dr. Fernanda Raya Tonetti led the project, and Dr. Cristina Llorente made important contributions.

New Lab-Grown Lip Cells Could Transform Research and Treatment for Disfiguring Lip Conditions

We use our lips to talk, eat, drink, and breathe; they signal our emotions, health, and aesthetic beauty. It takes a complex structure to perform so many roles, so lip problems can be hard to repair effectively. Basic research is essential to improving these treatments, but until now, models using lip cells -; which perform differently to other skin cells -; have not been available.

Harnessing the Power of Beneficial Bacteria to Fight Enterobacteriaceae

Antibiotic-resistant bacterial infections often occur in patients with chronic inflammatory intestinal conditions, such as inflammatory bowel disease, and in patients who have taken antibiotics for a long time. Gram-negative bacteria such as Enterobacteriaceae are a common cause of these infections and have few treatment options. Fecal microbiota transplants have shown promise to curb some of these infections, but their composition varies between batches and they aren't always successful.
