The Regulatory Effect of Vitamin D on Pancreatic Beta Cell Secretion in Patients with Type 2 Diabetes.

Increasing evidence suggests that vitamin D is one of the causes of accelerated development of Insulin Resistance (IR) and islet cell secret dysfunction. Numerous studies have shown that vitamin D can reduce inflammation, activate the transcription of the insulin receptors and related genes, and increase insulin-mediated glucose transport, thereby reducing IR. This article reviews the molecular mechanisms related to vitamin D deficiency and pancreatic β-cell dysfunction in patients with Type 2 Diabetes (T2D).
