Binding and internalization of the Helicobacter pylori vacuolating cytotoxin by epithelial cells

1 Oct 1996

Abstract excerpt

Many Helicobacter pylori strains produce a cytotoxin (VacA) that induces vacuolation in epithelial cells. In this study, binding and internalization of the cytotoxin by HeLa or AGS (human gastric adenocarcinoma) cells were characterized by indirect fluorescence microscopy. Cells incubated with the cytotoxin at 4 degrees C displayed a uniform fluorescent plasma membrane signal. Preincubation of the cytotoxin with...
