Probiotic helps treat diabetes in rats, could lead to human remedy

[Northerner]

Researchers have engineered a strain of lactobacillus, a human probiotic common in the gut, to secrete a Glucagen-like peptide (GPL-1). They then administered it orally to diabetic rats for 90 days and found the rats receiving the engineered probiotic had up to 30 percent lower high blood glucose, a hallmark of diabetes.
