New therapeutic strategy is emerging for type 2 diabetes

Diabetes is a disease in which blood sugar levels are high over a prolonged period (hyperglycemia). In the case of type 2 diabetes, this phenomenon which is caused by a disruption of the glucose metabolism develops progressively and insidiously. In France, the prevalence of diabetes is estimated at over 5 % of the 2015 population, with type 2 accounting for 90 % of cases. These figures do not include those who are unaware of their condition, particularly among the overweight or obese.

Hormone-sensitive lipase (HSL) is an enzyme which converts fats into fatty acids and releases them into the bloodstream. In obese patients, these fatty acids trigger the gradual insulin resistance at the origin of type 2 diabetes. Previous research by the Inserm team of Dominique Langin had shown that a decrease in HSL expression in the adipocytes led to a better response to insulin, a sign of good health for these cells.
