In this study, we investigated the inhibitory effect of Helicobacter pylori lipopolysaccharide on the binding of somatostatin to gastric epithelial cell membrane receptor, and assessed the effect of antiulcer agent, sucralfate, on this process. The assays conducted with the somatostatin receptor, purified from the solubilized epithelial cell membranes by affinity chromatography on Affi-Gel-[D-Tryp8]SRIF-14, revealed a dose-dependent inhibition in receptor-somatostatin binding by the lipopolysaccharide which reached a maximum of 94.1%. This effect of H. pylori lipopolysaccharide was countered by sucralfate that produced a 92.5% restoration in receptor-somatostatin binding at 70 μg/ml of the drug. The findings demonstrate that sucralfate is capable of reversing the interference by H. pylori lipopolysaccharide with somatostatin-receptor binding on gastric mucosal G-cells.
