    		 Endogenous Metabolite Apoptosis Inflammation/Immunology
    Protein A (SPA) is an immunoglobulin (Ig)-binding protein that exists on the bacterial surface and can be freely secreted into the extracellular environment. Protein A blocks opsonophagocytosis and induces B cell apoptosis in vitro by binding to the Fc region of antibodies and the Fab region of B cell receptors. Protein A can form toxic immune complexes with IgG, thereby inducing leukocyte necrosis. Protein A contributes to the virulence expression of Staphylococcus aureus. Protein A triggers allergic reactions in IgG-pretreated mouse models. Protein A can be used in studies related to immune system diseases .
