For generations, researchers studying hereditary angioedema have had to theorize about a disease they could not directly observe at its cellular origin. Now, for the first time, scientists have grown living liver cells from HAE patients themselves—cells that carry the actual mutations and reveal, with quiet precision, how a single misfolded protein can trap the body in cycles of dangerous swelling. The discovery not only illuminates a long-misunderstood mechanism but suggests that treatments already in use are working through pathways no one had fully mapped.
