The human gastrointestinal microbiota produces antagonistic activities against gastrointestinal bacterial pathogens. We undertook a study to investigate the mechanism(s) by which a Lactobacillus acidophilus strain of human microbiota origin antagoniz

In vivo Listeria monocytogenes infection results in the massive release of mucus by goblet cells into the lumen of the intestine. We have previously reported that apical infection by L. monocytogenes is followed by listeriolysin O (LLO)-dependent sti

Probiotic lactic acid strains are live micro-organisms that, when consumed in adequate amounts as part of food, confer a health benefit on the host. The scientific basis for the use of selected probiotic strains has only recently been firmly establis

Summary The secreted thiol-activated cytolysin listeriolysin O (LLO) was responsible for L. monocytogenes -induced high-molecular glycoproteins (HMGs) exocytosis in cultured human mucosecreting HT29-MTX cells. By biochemical analysis we demonstrate t

When the intracellular pathogen Listeria monocytogenes infects cultured human mucosecreting polarized HT29-MTX cells apically, it induces the stimulation of mucus exocytosis without cell entry. Using a set of isogenic mutants and purified listeriolys

The association of enterotoxigenic Escherichia coli expressing colonization factor antigen I (CFA/I) with the cultured human colon adenocarcinoma cell, a model of the mature enterocyte of the small intestine, is dependent on the binding of CFA/I to a

We report that the enterocytic cells of the HT-29 glc −/+ cell subpopulation strongly expressed two antimicrobial enzymes: the lysozyme and α 1 -antitrypsin. Moreover, we found that 20 to 30% of these cells expressed positive immunoreactivity usin

Enterotoxigenic Escherichia coli (ETEC) bearing the fimbrial colonisation factor antigens CFA/I, CFA/II, CFA/III, and the non-fimbrial antigen 2230 were tested for their ability to adhere to two cultured human intestinal HT-29 mucus secreting cell su

We have recently demonstrated that cultured human intestinal HT-29 and Caco-2 cell lines express receptors for the F1845 fimbrial adhesin harbored by the diarrheagenic C1845 Escherichia coli (Kerneis et al., Infect. Immun. 59 (1991) 4013–4018). Thi
