Ferroptosis Signaling in Pancreatic ß-Cells: Novel Insights & Therapeutic Targeting.

ABSTRACT

Metabolic stress impairs pancreatic ß-cell survival and function in diabetes. Although the pathophysiology of metabolic stress is complex, aberrant tissue damage and ß-cell death are brought on by an imbalance in redox equilibrium due to insufficient levels of endogenous antioxidant expression in ß-cells. The vulnerability of ß-cells to oxidative damage caused by iron accumulation has been linked to contributory ß-cell ferroptotic-like malfunction under diabetogenic settings. Here, we take into account recent findings on how iron metabolism contributes to the deregulation of the redox response in diabetic conditions as well as the ferroptotic-like malfunction in the pancreatic ß-cells, which may offer insights for deciphering the pathomechanisms and formulating plans for the treatment or prevention of metabolic stress brought on by ß-cell failure.
