Blood glucose levels are controlled by the autonomous nervous system. Parasympathetic axons directly influence islet function, leading to higher insulin release and lower levels of blood glucose. The results are published in December 2012 in PNAS. The autonomous nervous system responsible for the unconscious regulation consists of parasympathetic and sympathetic parts, managing the calm and …

Once a hormone is released it can stimulate its own production. This principle was previously proven by Professor Berggren’s group in relation to insulin. Now the same group shows the generality of the approach: glucagon secreting cells increase their production when they sense increasing levels of glucagon. The results are published in PNAS in December …
