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.
