Macrophages 'Eat' Insulin-producing Cells to Regulate Insulin

[skb]

Scientists have long known that pancreatic β cells increase during pregnancy and promptly return to their original number following birth. But scientists still do not understand the underlying mechanisms that cause the cells to go back to their original number.

In a significant breakthrough, a research group has discovered that a type of white blood cell called macrophages 'eat' (phagocytose) the pancreatic β cells, thereby revealing the process behind their return to previous levels after pregnancy.
