          Abstract

          Tamm-Horsfall glycoprotein (THP) contains manno-oligosaccharides that are recognized by type 1 fimbriae (F1) of Escherichia coli. In the present study, we examined the in vivo phagocytic activity of mouse peritoneal macrophages after treatment of bacteria with THP. At low THP concentrations (12.5 µg/ml and 50 µg/ml) no significant difference was observed in the phagocytosis of E. coli F1+. However, at high THP concentrations (500 µg/ml and 1250 µg/ml) we obtained a reduction of bacterial phagocytosis by mouse peritoneal macrophages.
