C1QBP and infective endocarditis: The data reported here is consistent with other studies where anti- gC1qR/p33 monoclonal antibodies have been shown in vivo to block S. aureus adhesion to endothelial cells treated with TNFα in a murine model, and to reduce S. aureus colonization of the aorta in a rat model of infective endocarditis [42], [43].
