According to new research published in the American Journal of Pathology, the molecule NF-κB is activated by inflammation, which plays a key role in autoimmune disease development. This makes NF-κB a prime candidate to track autoimmune activity, researchers say. Now scientists have engineered this molecule in mice so that it emits light when...
