Researchers at the University of Colorado School of Medicine have found a specific molecule that can prevent the development of type 1 diabetes in mice and has a similar effect on human cells from diabetic patients.
Aaron Michels, MD, an assistant professor of pediatrics and medicine, working with George Eisenbarth., MD, Ph.D., executive director of the Barbara Davis Center for Childhood Diabetes at the CU School of Medicine, tested a series of molecules before finding one most suitable by stopping diabetes from developing in mice. "We found that when you put specific molecules into specific structural pockets you can block the formation of diabetes," said Eisenbarth.
The researchers were looking for small molecules capable of occupying pockets along a protein binding groove. Some of the molecules got into these pockets and inhibited the presentation of insulin to immune cells while others enhanced it. Michels and Eisenbarth found that the compound Glyphosine enhanced insulin presentation and prevented mice genetically modified to develop type 1diabetes. It had the same effect on human cells. The mice remained disease-free as long as they received daily injections of the compound. It was not as effective on mice that already had diabetes.
