Official title
Investigating the Role of a4b7 Integrin as a Therapeutic Target in Eosinophilic Esophagitis
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The overall objective of this preclinical study is to further the investigators mechanistic understanding of the role that the α4β7 and mucosal addressin cell adhesion molecule (MAdCAM-1) pathway plays in mediating eosinophil recruitment in EoE. To accomplish this, the investigators aim to (1) determine the baseline and dynamic patterns of α4β7 integrin expression on circulating and tissue eosinophils in EoE and in the setting of non-EoE esophageal eosinophilia (e.g., reflux esophagitis) and (2) determine the complete profile of eosinophil integrin molecules that may play a role in active EoE.
