Adhesion of Helicobacter pylori and Escherichia coli to human and bovine surface mucus cells in vitro

Abstract: Helicobacter pylori shows in vivo a specific affinity for epithelial surface mucus cells (SMC) of the human stomach. We studied the in vitro adhesion of five different H. pylori strains and one non-pathogenic Escherichia coli-strain to (a) human antral SMC, obtained during gastroscopy; (b) human tumour SMC, from a carcinoma cell line (CRL 1739 AGS); and (c) bovine SMC, obtained from the abomasum. SMC of different origin were characterized by means of electron microscopy and immunohistochemistry, and showed sim… Show more

“…Dabei kommt nach Mazur [15] dem transmembranösen Wassertransport beim Einfrieren und Auftauen eine zentrale Rolle zu. Die Lagerungsdauer selbst ist von untergeordneter Bedeutung, solange die Lagerungstemperatur hinreichend tief ist; für wäßrige Systeme ist dies nach Franks [16] bei Temperaturen unterhalb der sog. Glasübergangstemperatur der Fall.…”

“…Es haftet an den Epithelzellen der Schleimhaut mittels Adhäsionsfüßchen. Nach der Adhäsion flacht die Zelloberfläche ab und die Microvilli gehen verloren [16]. Die Mehrzahl der Keime lebt im Mucusgel, einige haften an den Epithelzellen.…”

“…Using this reductionist system, H. pylori is shown to adhere to the surface of these cells (Nilius et al 1994) and induce effects that include nuclear factor (NF)-jB activation (Keates et al 1997) and the up-regulation of epidermal growth factor receptor (EGFR) (Keates et al 2007), two known inducers of H-ferritin mRNA expression that may contribute to increased iron storage in gastric epithelial cells (Konijn et al 1999). A recent study found evidence of increased transferrin internalisation in H. pylori-infected polarized Madin Darby Canine Kidney (MDCK) cells (Tan et al 2011) but to date any effect of H. pylori infection on gastric epithelial cell iron homeostasis has not been determined.…”

“…AGS cells were used to accomplish these goals as have been employed in our earlier studies [9,10]. This human cell line has been used by many investigators for over a decade to study various aspects of gastric epithelial biology [11][12][13].…”
