A Toronto-led team of researchers has discovered a trigger for Type 1 diabetes, a breakthrough that has long evaded scientists and could lead the way to preventing the disease. The team found that abnormal nerve endings in the insulin-producing cells of the pancreas initiated a chain of events that caused Type 1 diabetes in mice. When they removed the nerve cells, the mice did not develop the disorder. That means diabetes may be a disease of the nervous system, not just an autoimmune disease, said Dr. Hans Michael Dosch, a senior scientist at the Hospital for Sick Children and the study's main investigator. In a reversal of what they expected, the researchers also found injecting substance P a chemical secreted by nerve cells into mice whose islet cells were inflamed and on the way to being destroyed not only eliminated the inflammation but reversed it. "The blood glucose normalizes overnight and it stays low for weeks to months this is with a single shot," Dosch said. "We now have 4-month-old mice that are non-diabetic that used to be diabetic" a period equivalent to six to eight years in humans. Experts say the findings, reported yesterday in the journal Cell, will change the way scientists think about diabetes. "It really is a breakthrough for the diabetes community," said Pam Ohashi, a professor of immunology at the University of Toronto. Dosch has immediate plans to move his research from mice to humans. He is launching a clinical trial in January to figure out if patients who have a high risk of Type 1 diabetes have the same sensory nerve abnormalities. "If they do, then we have fantastic new therapeutic strategies," said Dosch, who is also a professor of pediatrics and immunology at U of T.
