From: Helicobacter pylori Lipopolysaccharide Hinders Polymorphonuclear Leucocyte Apoptosis
Analysis of neutrophil apoptosis by TUNEL (TdT-mediated dUTP nick end labeling) method. A, Control cells at 2 hours of culture show a few apoptotic cells. B, Only a few positive nuclei can be identified at 12 hours in PMNL treated with BCF from 60190 H. pylori strain. C, Almost all control cells at 12 hours of culture revealed nuclear positivity. D, Using B287, numerous apoptotic cells in PMNL treated with BCF from 60190 strain were noted at 12 hours. E, Very few positive nuclei were observed at 12 hours in PMNL treated with BCF from G21 H. pylori strain and F, with BCF from Escherichia coli.
