As a pathogen, Staphylococcus aureus utilizes protein A, along with a host of other proteins and surface factors, to aid its survival and virulence. To this end, protein A plays a multifaceted role: 1. By binding the Fc portion of antibodies, protein A renders them inaccessible to the opsonins, thus impairing phagocytosis of the bacteria via immune cell attack. 2. Protein A facilitates the adherence of S. aureus to human von Willebrand factor (vWF)-coated surfaces, thus increasing t… WebBacterial Antibodies.
