Diabetes researchers believe that the disorder is caused by some type of immune reaction gone awry - immune cells are "trained" in the thymus gland to recognize the body's own cells and protect them from destruction. For some reason, this education doesn't occur properly in Type 1 diabetes patients, and the immune system sees the pancreatic beta cells as foreign. Melton's team is currently working to generate thymus cells from diabetic patients in the same way the team created the beta cells, in order to put all the players together in a lab dish, in a kind...
...researchers are hoping to learn whether diabetes begins in the thymus or in the pancreas, where beta cells somehow change and are no longer recognized or protected by the immune system. "We still really don't know the mechanism of what causes this disease," says Melton. "We don't know which cell is initially responsible, and we don't know if certain people are destined to get it, or if there are things we can do to prevent it, or how to reverse...
