This research uses fruit flies to study the STING immune pathway, revealing how cells detect viral infections. By identifying Nemo as a missing connector protein active only during infection, the work clarifies how immune responses are triggered. These insights may guide future therapies that balance antiviral defense while limiting immune damage.

Type 1 diabetes occurs when the immune system mistakenly destroys insulin-producing cells. This research shifts focus from disease-causing genes to protective genes found in rare individuals. By examining the first immune–pancreas interaction at the atomic level, it reveals how protection rewires immune responses and offers new paths to preventing the disease.
