Interaction between Mitochondria and the Endoplasmic Reticulum: Implications for the Pathogenesis of Type 2 Diabetes Mellitus

الملخص EN

Mitochondrial dysfunction and endoplasmic reticulum (ER) stress are closely associated with β-cell dysfunction and peripheral insulin resistance.

Thus, each of these factors contributes to the development of type 2 diabetes mellitus (DM).

The accumulated evidence reveals structural and functional communications between mitochondria and the ER.

It is now well established that ER stress causes apoptotic cell death by disturbing mitochondrial Ca2+ homeostasis.

In addition, recent studies have shown that mitochondrial dysfunction causes ER stress.

In this paper, we summarize the roles that mitochondrial dysfunction and ER stress play in the pathogenesis of type 2 DM.

Structural and functional communications between mitochondria and the ER are also discussed.

Finally, we focus on recent findings supporting the hypothesis that mitochondrial dysfunction and the subsequent induction of ER stress play important roles in the pathogenesis of type 2 DM.
