HLA Demographics Study in Adults With Type 1 Diabetes

This study measures how “blood fats” move in the body after fasting and controlled eating, comparing people with type 1 diabetes to those without diabetes. It may help researchers understand diabetes-related differences in lipid (fat) handling and improve future treatments.

This study looks at immune cells in children who were recently diagnosed with type 1 diabetes. It involves one extra blood draw to better understand how the immune system attacks the pancreas. If you join, no new treatments are given—just observation and analysis of your child's immune cells.

This study looks at people with type 2 diabetes to understand their health. If you join, you'll have simple measurements taken like height, weight, and grip strength.

This study looks at immune (defense system) and blood-sugar changes in people with type 1 diabetes, and in some other diabetes or autoimmune hormone conditions. It includes people who will have a specific abdominal surgery so doctors can safely study lymph node tissue.

This study measures “circulating biomarkers” (blood-based signals) in people with type 1 or type 2 diabetes, and in some people without diabetes who test positive for certain diabetes antibodies. The goal is to understand what these blood signals can tell us about diabetes development and progression.

This study looks at using a finger-prick test instead of a standard blood draw for the oral glucose tolerance test (OGTT), which measures how your body handles sugar. It may help young people at risk for or with early type 1 diabetes avoid repeated needle sticks.
