Summary: We have discovered and synthesised a single protein from a parasitic worm that prevents T1D (called FhHDM). Knowing that FhHDM prevents T1D inspires us to find out how it does it. To date we know that FhHDM modulates the function of both mouse and human immune cells. The aim of this proposal is to understand the mechanisms by which FhHDM generates and sustains anti-inflammatory immune responses to prevent T1D. This will allow the development novel therapeutics to prevent and cure T1D.
