Monitoring T cells could prevent type 1 diabetes
Scripps Research scientists have shown that analyzing a certain type of immune cell in the blood can help identify people at risk of developing type 1 diabetes, a life-threatening autoimmune disease. The new approach, if validated in further studies, could be used to select suitable patients for treatment that stops the autoimmune process—making type 1 diabetes a preventable condition.
In the study, which appeared in Science Translational Medicine, the researchers isolated T cells (a type of immune cell) from mouse and human blood samples. By analyzing the T cells that can cause type 1 diabetes, they were able to distinguish the at-risk patients who had active autoimmunity from those who had no significant autoimmunity—with 100% accuracy in a small sample.
