Eosinophil progenitor levels correlate with tissue pathology in pediatric eosinophilic esophagitis.

Abstract

Blood eosinophil progenitors (EoPs) correlate with tissue pathology during active eosinophilic esophagitis (EoE), providing additional evidence for blood EoP levels as a biomarker for disease activity and suggesting a role for EoPs in EoE pathogenesis.
