AlphaE Integrin Expression Is Increased in the Ileum Relative to the Colon and Unaffected by Inflammation
2018
Background
Recent findings suggest that αE expression is enriched on effector T cells and that intestinal αE+ T cells have increased expression of inflammatory cytokines. αE integrin expression is a potential predictive biomarker for response to etrolizumab, a monoclonal antibody against β7 integrin that targets both α4β7 and αEβ7. We evaluated the prevalence and localization of αE+ cells as well as total αE gene expression in healthy and inflammatory bowel disease patients.
