In type 2 diabetes, the body stops responding efficiently to insulin, a hormone that controls blood sugar. To compensate for the insensitivity to insulin, many diabetes drugs work by boosting insulin levels; for example, by injecting more insulin or by increasing the amount of insulin secreted from the pancreas. The new study, published in the June 9 issue of PLoS ONE, showed that a different approach could also be effective for treating diabetes — namely, blocking the breakdown of insulin, after it is secreted from the pancreas.
