The influence of adhesive and invasive properties of Staphylococcus aureus defective in fibronectin-binding proteins on secretion of interleukin-6 by human endothelial cells

Fibronectin-binding proteins (FnBP) are surface adhesins of Staphylococcus aureus documented to be virulence attributes in, for example, endovascular infections. By using mutants of S. aureus defective in the FnBPA and B genes we have investigated whether these adhesins affect cytokine expression in human umbilical vein endothelial cells (HUVEC). S. aureus expressing FnBPA and B adhered to and were internalized into HUVEC to a greater extent compared to mutants defective in expression of FnBP. Production and release of IL-6 was higher from endothelial cells infected with the parent FnBP-expressing strain compared to the FnBP-defective mutants. These results indicate that adhesion to and invasion of S. aureus into endothelial cells are important regulators of cytokine expression. © 2006 The Authors.
