"The main point of this study is trying to shift the emphasis in thinking of type 2 diabetes as a purely metabolic disease, and instead emphasize the role of the immune system in type 2," said study co-author Dr. Daniel Winer, an endocrine pathologist at Toronto General Hospital in Canada. When the research began, Winer was a postdoctoral fellow at Stanford University in California.
The researchers have identified immune system antibodies in people who are obese and insulin-resistant that aren't present in people who are obese without insulin resistance. They also tested a drug that modifies the immune system in mice fed a fatty diet, and found that the medication could help maintain normal blood sugar levels."
