A California reseach team was working on an enzyme that they thought could cure obesity. This research came our of the Genome project that had been fostered by the elder Bush in the late 80s.
In order to test their enzyme treatment they had to develope experimental mice who were obese and then treat them. they did,(creatre obese mice) they treated them and voi la they were cured!!!! BTW obese mice are diabetic. When their obeseness was cured so was their diabetes. Diabetes can be cured we just need to fund the research. The difficulty is delivering the enzyme. An inhaler spray so that the enzymen can get into the blood stream without going through the digestive tract where it would be "digested" is the trick. And in this treatment there is no stemcell or other tricky procedures. Just organically producing the enzyme.
Don't forget, there are two types of diabetes. The treatments are similar, but the causes and physiology of the two diseases are night and day. Dr. Faustman's treatment only works with type I's who's diabetes is caused by an autoimmune reaction to the islet cells. Type II is what has to be cured to cut Medicare.
