Comparable integrin expression on T-cells from BE and duodenal tissue.

<p>The expression was analysed of α4 (panel A) and β7 (panel B) (arbitrary units, mean fluorescence) by CD3⁺ cells in <i>ex vivo</i> cultures of BE and duodenum of BE patients (DUO BE) and controls (DUO control) (black bar: DUO control, dark grey bar: DUO BE, light grey bar: BE). Also, the percentages of CD3⁺α4⁺-cells (panel C) and CD3⁺α4β7⁺-T-cells (panel D) of the CD3⁺-population in ex-vivo cultures of BE and duodenum from both groups were determined (<b>ns</b> not significant). There was no difference in expression of α4 and β7 and percentage of α4⁺ and α4⁺β7⁺ cells between duodenum of BE patients (DUO BE, n = 7) and duodenum of controls (DUO control) (n = 5).
