CHICAGO (Reuters) - Two popular leukemia drugs, Gleevec and Sutent, kept lab mice from developing type 1 diabetes and put 80 percent of diabetic mice in remission, an international team said on Monday.
Both drugs -- Gleevec, or imatinib, made by Novartis AG and Sutent, or sunitinib, made by Pfizer Inc -- worked by depressing the immune systems in the mice, which maintained normal blood sugar levels even after treatment ended.
"There are very few drugs to treat type 1 diabetes, especially after disease onset, so this benefit, with a drug already proven to be safe and effective in cancer patients, is very promising," Jeffrey Bluestone of the University of California, San Francisco, said in a statement.
"The fact that the treated mice maintained normal blood glucose levels for some time after the drug treatment was stopped suggests that imatinib and sunitinib may be 'reprogramming' their immune systems in a permanent way," said Bluestone, whose research appears in the Proceedings of the National Academy of Sciences.
Type-1 diabetes affects an estimated 5 to 10 percent of the 20 million Americans with diabetes. Also called juvenile diabetes, it has different causes from the more common type-2 diabetes that is linked with obesity, poor diet and a lack of exercise.
Type 1 diabetes is an autoimmune disease caused by the destruction of insulin-producing cells in the pancreas.
Both Gleevec and Sutent inhibit tyrosine kinases, enzymes that are needed for cell communication and growth and are linked with inflammation and immunity.
Bluestone and colleagues wondered if these drugs could block some of the same tyrosine kinases involved in the development of type 1 diabetes.
They tested the drugs in mice predisposed to type 1 diabetes and found that the drugs kept the mice from developing diabetes.
They also tested them in mice with the disease and showed the drugs put the disease in remission in 80 percent of the animals after only eight to 10 weeks of treatment.
They said the drugs appear to block receptors of a tyrosine kinase not known to be involved in diabetes. This enzyme, known as platelet-derived growth factor receptor, or PDGFR, regulates cell growth and division, and also plays a key role in inflammation.
"This study opens up a new area of research in the field of type 1 diabetes, and importantly, opens up exciting opportunities for developing new therapies to treat this disease and other autoimmune diseases," Dr. Arthur Weiss of University of California, San Francisco, who worked on the research, said in a statement.

This is really amazing, I'll defiantly be following this story.

Wonder what the FDA has to say about it.

they'll prolly find a way to stop it or make it illegal. there's no money in curing a disease :frown1:

I sure hope they don't do that. People need as much help as they can get.

i hope they don't either. but as i said, there's no money in curing diseases. which is why i don't believe this country has good or bad health care. we have sick care.

No money in curing diseases? Did you not see my bills for cancer treatment? (not to mention the five year run of after care, with blood tests and about a zilllion other tests-of which I'm not even halfway done with).

As to treatments, the government is of course against health care, mainly because they can't profit from it. Of course, it could be argued that since the percentage of people with diabetes is on the rise, that the government would join in, if only to woo the lobbyists from the giant pharmaceutical companies. A wonderful government sponsored campaign about diabetes tied in with Glaxo and its new diabetes treatment which would feature a pill, capsule or shot at about $50.00 per day. Pharmaceutical company makes their money and shoots much of it over to the politician. And the machinery used for some of the testing-again, corporations manufacture these things and their tidy profits help them to place support behind certain politicians. (you might notice I'm somewhat cynical).
