IL5 and eosinophilic esophagitis: A smaller study profiling 1088 esophageal T cells from EoE patients showed similar results, including the presence of GATA+ TH2-like effector T cells, which produced high levels of IL-5 and IL-1313, but did not detect IL-9-expressing T cells nor eosinophils, mast cells, or type 2 innate lymphoid cells (ILC2s).
