Recruitment of CD55 and CD66e Brush Border-Associated Glycosylphosphatidylinositol-Anchored Proteins by Members of the Afa/Dr Diffusely Adhering Family of<i>Escherichia coli</i>That Infect the Human Polarized Intestinal Caco-2/TC7 Cells

Abstract excerpt

The Afa/Dr family of diffusely adhering Escherichia coli (Afa/Dr DAEC) includes bacteria expressing afimbrial adhesins (AFA), Dr hemagglutinin, and fimbrial F1845 adhesin. We show that infection of human intestinal Caco-2/TC7 cells by the Afa/Dr DAEC strains C1845 and IH11128 is followed by clustering of CD55 around adhering bacteria. Mapping of CD55 epitopes involved in CD55 clustering by Afa/Dr DAEC was...
