IL-4 AND IL-13 ARE TWO OF THE KEY DRIVERS OF TYPE 2 INFLAMMATION THAT
RESULT IN PATHOLOGICAL CHANGES AND SYMPTOMS OF EoE2-4

IL-4 Actions5,7
  • Amplifies and sustains type 2 inflammation
  • IgE antibody production
  • Mast cell proliferation and survival
Overlapping actions4,5,7,8
  • Epithelial barrier disruption
  • Eosinophil activation
  • Tissue inflammation
IL-13 ACtions4,7
  • Fibrosis
  • Esophageal remodeling
  • Esophageal muscular dysfunction
Common symptoms2,4,9,10

Speaker Profile

Dr. Wechsler, MD, MSCI

Typically when I’m talking to a patient for the first time about a new EoE diagnosis, for me, I’m really focused in on the fact that this is chronic disease. They’re most likely going to have it lifelong and that if we don’t really treat this disease, it’s going to lead to narrowing of the esophagus, which means food’s going to get stuck. I think that’s probably more challenging when they’re young and it’s really hard to perceive those. When you experience it, it’s probably even more real.
