Some recent headlines I thought some of you might be interested in. Enjoy.

Leptin Therapy in Animal Models Shows Promise for Type 1 Diabetes -

"UT Southwestern researchers, using mouse models, found that leptin administered instead of insulin showed better management of blood-sugar variability and lipogenesis, the conversion of simple sugars into fatty acids. Leptin is a hormone produced by fat cells and involved in the regulation of body weight."

"Benefits of letpin's glucose-lowering action appear to involve the suppression of glucagon. Normally, glucagon is released when the glucose level in the blood is low, thanks to supervision by insulin release from neighboring cells. In insulin deficiency situations, however, glucagon levels are inappropriately high and cause the liver to release excessive amounts of glucose into the bloodstream. This action is opposed by insulin, which tells the body's cells to remove sugar from the

How Weight-Loss Surgery Reverses Type 2 Diabetes: New Study Offers Explanation -

"It has been thought that reduction of blood sugar, which indicates a reversal of type 2 diabetes, in patients following bariatric surgery was due to post-surgery weight loss," Havel said. "This study, however, supports the observations from a number of earlier clinical studies reporting that diabetes is often improved prior to substantial weight loss. It also suggests that endocrine changes in hormones produced by the gastrointestinal tract may contribute to the early effects of bariatric surgery, in addition to the later effects of weight loss."

"In addition, results from the study also demonstrated that the ileal interposition surgery increases production of bile acids, which are involved in fat metabolism and can increase the production of GLP-1, the hormone that improves insulin secretion and insulin sensitivity," Havel said. "This could contribute to the delay in the onset of type 2 diabetes that we observed in the rats in this study."
