T1D Facts

What you need to know about type 1 diabetes, how it progresses, and why it’s so important to detect it in its earliest stage.

Type 1 diabetes is a disease of the immune system, the body's system for fighting infection. In people with T1D, the immune system mistakenly attacks healthy insulin-producing cells, called beta cells, and destroys them. TrialNet's goal is to detect T1D in its earliest stage and slow down or stop disease progression.
