  "textContent": "A team of researchers at the Icahn School of Medicine at Mount Sinai, Weill Cornell Medicine, and other institutions have uncovered a key biological explanation for why eczema so often starts in childhood. The study, in young mice, found that some types of immune cells in early-life skin are more reactive than those in adults, a difference that may help explain why children are more vulnerable to inflammation and allergic skin disease.",
