Neutralizing antibodies are effective at preventing infection or toxicity mediated by pathogens or their toxic products. In fact, nearly all vaccines currently in use function by eliciting neutralizing antibodies. One example is the tetanus vaccine, in which neutralizing antibodies are generated against an inactivated form of the tetanus toxin (the tetanus toxoid). The most important feature of a neutralizing antibody is having high affinity for the antigen. being efficient at activating the complement cascade. having a high degree of multivalency, such as being a pentamer or hexamer of immunoglobulin monomers. being present at a high concentration in the circulation. 0 0 0 0
Some pathogenic microorganisms encode proteins, such as the Staphylococcus Protein A, that bind to immunoglobulin constant region domains with high affinity. These microbial proteins provide a benefit to the microorganism by: Preventing antibodies bound to the microbe from binding to Fc receptors on phagocytes Blocking the binding of anti-microbial antibodies to the pathogen surface Cleaving the antibody into fragments that separate the antigen-binding region from the effector function Inducing aggregation of the anti-microbial antibodies by multivalent binding to the pathogen-derived protein Preventing the antibody from neutralizing the pathogen

Antibody heavy and light chain polypeptides consist of repeated domains, each of which is ~110 amino acids and folds up into a compact three-dimensional structure known as an ‘immunoglobulin domain.’ These immunoglobulin domains are: Mixed and matched between different antibody heavy and light chains to produce variability Always identical to each other within a single antibody heavy chain or light chain polypeptide Always differ in amino acid sequence between different light chain polypeptides in both of the two light chain immunoglobulin domains Similar but not identical in amino acid sequence when comparing the domains in a single heavy chain polypeptide Identical in amino acid sequence for every domain when comparing different antibody heavy chain polypeptides to each other
