Group 2 innate lymphocytes (ILC2) are enriched in active eosinophilic esophagitis

J Allergy Clin Immunol. 2015 Sep;136(3):792-794.e3. doi: 10.1016/j.jaci.2015.05.048. Epub 2015 Jul 30.

Abstract

Group 2 innate lymphoid cells (ILC2s) produce high levels of IL-5 and IL-13, both of which are important pathogenic mediators in eosinophilic esophagitis (EoE). ILC2s have not been previously described in EoE. Our study demonstrates the novel finding that ILC2s are increased in esophageal biopsies from EoE patients with active disease compared with inactive EoE and non-diseased controls, implicating these cells in EoE pathogenesis.
