Cytokines shown to be a cause of type 2 diabetes

In the first large scale, multiethnic study of its kind, researchers at UCLA have confirmed the role played by three particular molecules known as cytokines as a cause of Type 2 diabetes, and further, have identified these molecules as early biological markers that may be used to more accurately predict future incidences of diabetes among apparently healthy individuals.
