[Zinc and type 2 diabetes].

Pancreatic β cells contain the highest amount of zinc among cells within the human body, and hence, the relationship between zinc and diabetes has been a topic of great interest. While many studies demonstrating possible involvement of zinc deficiency in diabetes have been reported, precise mechanisms how zinc regulates glucose metabolism are still far from understood. Recent studies revealed that zinc can transmit signals that are driven by a variety of zinc transporters in a tissue and cell-type specific manner and deficiency in some zinc transporters may cause human diseases. Here, we review the role of zinc in metabolism particularly focusing on the emerging role of zinc transporters in diabetes.
