|
51 |
15917853
|
Recent evidence suggests that adiponectin, a protein whose circulating levels are decreased in obesity, has anti-inflammatory properties, and also appears to enhance potently insulin action and therefore appears to function as a signal produced by adipose tissue that influences whole-body glucose metabolism.

|
In obesity and insulin resistance, increased secretion of proinflammatory cytokines and decreased secretion of adiponectin from adipose tissue, increased circulating levels of free fatty acids, and postprandial hyperglycemia can all alter gene expression and cell signaling in vascular endothelium, cause vascular insulin resistance, and change the release of endothelium-derived factors.
