Smart probiotics can sense high blood sugar and release GLP-1 on demand
Researchers have developed an engineered probiotic called GIFT that senses high blood sugar levels and releases GLP-1 to regulate glucose. This 'living drug' successfully managed blood sugar spikes in animal models, offering a potential future treatment for diabetes.
Why it matters
This innovation could lead to more effective, automated management of diabetes, reducing the burden of daily monitoring and medication.

GIFT cells are orally administered to diabetic mice and monkeys, temporarily colonize the intestine and secrete GLP-1 in response to high glucose levels, leading to an abolishment of persistent hyperglycemia.

DOI: 10.1038/s41586-026-10909-6 For people living with diabetes, managing blood sugar can mean constantly watching the clock, keeping meals and medications on schedule and staying alert to changes in glucose levels. While little can be done about timed meals, researchers have developed a biological system that detects rising blood sugar levels and automatically responds by releasing medication to bring glucose back down.
