Researchers report that they have discovered the cause of eosinophilic eophagitis (EoE), a hard-to-treat food allergy. In EoE, large numbers of white blood cells, known as eosinophils, accumulate in the lining of the esophagus (the tube that connects the mouth to the stomach), causing chronic inflammation. Led by a team at Cincinnati Children’s Hospital, investigators have found a new genetic and molecular pathway in the esophagus. This discovery, reported online today in Nature Genetics, opens the door to new therapies for EoE, which has been diagnosed in a growing number of children and adults over the past decade.

The study found that EoE is triggered by the interplay between epithelial cells, which help form the lining of the esophagus, and a gene called CAPN14. When the epithelial cells are exposed to an immune hormone called interleukin 13 (IL-13), which is known to play a role in EoE, they cause…
