Study Says Iron May Contribute to Type 2 Onset

Danish researchers report that high levels of transferrin may contribute to the destruction of insulin-producing beta cells in the pancreas. Transferrin is a glycoprotein that binds with iron and transfers it to cells.

The researchers at the University of Copenhagen were looking to expand on previous studies indicating that higher levels of stored and ingested iron are associated with a higher risk of type 2. In their experiments on mice, they found that removing transferrin from genetically modified animals protected them against the onset of diabetes. They also found that elevated transferrin was associated with a two- to threefold increased risk of developing type 1 or type 2.
