Pancreatic β‐cell function is essential for the regulation of glucose homeostasis and its impairment leads to diabetes mellitus. Besides glucose, the major nutrient factor, inputs from neural and humoral components and intraislet cell–cell communication act together to guarantee an appropriate pancreatic β‐cell function. Data obtained over the last 5 years in several laboratories have revitalized a controversial concept, namely the autocrine feedback action of secreted insulin on β‐cell function. While, historically, insulin was suggested to exert a negative effect on β‐cells, recent data provide evidence for a positive role of insulin in transcription, translation, ion flux, insulin secretion and β‐cell survival.
