Brain might become target of new type 1 diabetes treatments

A new analysis published in The Journal of Clinical Investigation reveals how leptin affects the brain and its potential use in future therapeutics for type 1 diabetes. Leptin helps regulate appetite and body weight, and insufficient levels lead the brain to activate circuits that mobilize energy sources, including glucose and ketones.

Mayo Clinic researchers find “sugar coating” cells can protect those typically destroyed in type 1 diabetes

Researchers identified a sugar molecule called sialic acid that helps cancer cells evade the immune system. By engineering beta cells to produce this molecule, they found it possible to tolerate these cells and prevent their destruction. The study offers new hope for treating type 1 diabetes without immunosuppression.
