Serotonin expression found in islets

by

Diabetes is often associated with depression. Perhaps this study may offer a little more light on the dark subject?

 An experimental study conducted at the University of California in San Francisco reveled the islets are responsible for expressing all genes associated with serotonin. This may finally put some science behind the empirical observations.  

 Serotonin is a neurotransmitter that regulates sleep, hunger, and happiness. Although serotonin functions in the brain – about 90% of serotonin is produced in the digestive tract. When food enters the gut, the muscles of the gut contract around the food. Excess serotonin is stored by platelets, where it is carried into the bloodstream.

 The ‘boss’ of serotonin is the islets. Turns-out everything from synthesis, packaging, and secretion is mandated by the islets. Go figure I think this links islets and the ‘feel-good’ neurotransmitter quite nicely. Food affects our glucose level. Food can affects our mood. Islets manage our glucose level. Shouldn’t islets manage our mood, too?
