Tamm-Horsfall glycoprotein (THP), which is synthesized by renal tubular cells, is the most abundant protein in normal human urine. Although its physiological function remains unclear, it has been proposed that THP may act as a defense factor against urinary tract infections by inhibiting the binding of S- and P-fimbriated Escherichia coli to renal epithelial cells. Because THP-related proteins are also found in the superficial layers of the oral mucosa, THP may interfere with the cytoadherence of pathogenic bacteria that colonize mucosal surfaces other than those of the urogenital tract. It has been shown that THP binds to virulent Bordetella pertussis and reduces its adherence to both renal and pulmonary epithelial cells. This cytoadherence inhibitory effect was not observed with a B. pertussis mutant lacking the pertussis toxin (PTX) operon, and was dependent on the direct interaction of THP with the S2 subunit within the PTX B oligomer. It has also been shown that the glycosylation moiety of THP is crucial for its binding to PTX. The THP-PTX interaction was exploited to develop an affinity chromatography method that allows a one-step purification of active PTX. These observations suggest that besides its anti-adherence activity, THP may also trap toxins produced by pathogenic bacteria that colonize mucosal surfaces.
