Scientists have discovered a novel protein-based treatment that restores normal blood-sugar levels in diabetic mice for a period of seven days. The study, published in Nature today, reveals a possible new therapeutic pathway for people who suffer from type 2 diabetes. We had no idea that this molecule would have this effect, says Michael Downes, a diabetes researcher at the Salk Institute for Biological Studies in California and a co-author of the study. But it appears that the molecule restores insulin sensitivity in diabetic mice.
