New research suggests that inflammation, which is widely viewed as contributor to type 2 diabetes, is actually crucial for maintaining good blood sugar levels.
"This finding is completely contrary to the general dogma in the diabetes field that low-grade inflammation in obesity causes insulin resistance and type 2 diabetes," says lead author of the study Umut Ozcan, from the Division of Endocrinology at Children's Hospital Boston.

The study also suggests a new model for understanding type 2 diabetes, in which obesity may interfere with the ability of people's cells to respond to inflammatory signals.
"It may be that inflammatory pathways are not working optimally and there could be a resistance to cytokines which mediates the inflammation," Ozcan said.
"This could be a paradigm shift for the field," he added.
The study was recently published in the journal Nature Medicine.
