The role of insulin as a boost to the immune system to improve its ability to fight infection has been detailed for the first time by Toronto General Hospital Research Institute (TGHRI) scientists.

TGHRI scientists have identified a specific insulin signaling pathway that, when activated, revs up the response of T cells in the immune system to divide rapidly and secrete cytokines, chemical messenger proteins that activate the rest of the immune system. A fast and effective immune response protects us against disease and life-threatening infections by destroying infected cells or microbes, while a wrong or inefficient one can cause immune system disorders or diseases to develop.

Then why do folk with diabetes always seem to get lingering infections, whether on insulin or not?
