There was a study out of Canada where they neutralized pain-nerves of the pancreas and stopped diabetes. From the National Post:

In a discovery that has stunned even those behind it, scientists at a Toronto hospital say they have proof the body’s nervous system helps trigger diabetes, opening the door to a potential near-cure of the disease that affects millions of Canadians.
Diabetic mice became healthy virtually overnight after researchers injected a substance to counteract the effect of malfunctioning pain neurons in the pancreas. “I couldn’t believe it,” said Dr. Michael Salter, a pain expert at the Hospital for Sick Children and one of the scientists. “Mice with diabetes suddenly didn’t have diabetes any more.”
Shhhhh . . . . . .
Mice are a convenient mammalian model, but they have their limitations.
Could we cool it on the Big Pharma cabal that withholds cures? There are a lot of unknown unknowns, i.e. the investigators don't know what they are still ignorant about. A lot of basic biomedical science has yet to be done. There are a lot of physicians involved who want to provide cures, who would consider withholding cures unethical, and who have jumbo egos.
