In addition to oxidative stress, excess iron can also promote inflammation in beta cells. Chronic inflammation is known to play a role in the development of insulin resistance and beta cell dysfunction. Iron-induced inflammation can further impair beta cell function and contribute to the progression of diabetes.

Furthermore, iron overload in beta cells can disrupt the normal regulation of iron homeostasis. Iron is tightly regulated within cells to ensure proper function and prevent iron-related toxicity. Excessive iron accumulation in beta cells can disrupt this regulation and lead to cellular dysfunction.

In summary, iron plays a complex role in beta cell dysfunction. Excess iron accumulation can lead to oxidative stress, inflammation, and disruption of iron homeostasis, all of which can impair beta cell function and contribute to the development and progression of diabetes.
