    Immune tolerance: Self cells and tissues are not normally attacked. The recent anthrax mail attacks in the United States have demonstrated the vulnerability of the public to biological terrorism and stimulated a. Antibodies defend us against infection by binding to viruses and microbial toxins, and activated complement components work together to attack the invaders.
    Am J Trop Med.

    The binding of antibodies to invading pathogens also recruits various types of white blood cells and a system of blood proteins, collectively called complement discussed in Chapter Protection and suppression of the humoral response in mice mediated by a monoclonal antibody against the M epitope of Brucella.

    Antibody-antigen interactions. We shall see later that many other proteins on the surface of lymphocytes and other cells, many of which function as cell-cell adhesion molecules discussed in Chapter 19contain similar domains and hence are members of a very large immunoglobulin Ig superfamily of proteins.

    These molecules then insert into the plasma membrane, where they function as receptors for antigen.

An aggressor could attempt to defeat a passive antibody defense by engineering the agent to express antigenic changes, proteases, or antibody-binding proteins. Since antibody reagents are almost always pathogen specific, the market for antibody-based therapies is often much smaller than that for drugs with broad antimicrobial activity.

    The similarity in their domains suggests that antibody chains arose during evolution by a series of gene duplications, beginning with a primordial gene coding for a single amino acid domain of unknown function. The antigenic more

    This makes it difficult for the immune system to attack them, because it "This research has taken us on an exciting journey," says A/Prof Christ.

    Antitoxins for diseases such as botulism;; Human immune globulin preparations (passive antibody protection) against various bacteria and viruses.
    By attaching themselves to some invading microbes, other antibodies can render such microorganisms immobile or prevent them from penetrating body cells.

    This article reviews the activity of humoral immunity against several biological agents, discusses the advantages and disadvantages of an antibody-based defense strategy Tableand proposes stockpiling specific antibodies for use in the event of biological attacks.

    J Physiol Paris. Hence, stockpiles of MAbs can easily be made obsolete by biological agents that exhibit antigenic differences. These studies indicate the existence of multiple antigens in Brucella spp. J Virol. For example, administration of human IgG may require only a one-time infusion, whereas antimicrobial therapy is likely to require continuous administration during the period of exposure and following infection.

    1. Each type of tail region gives the antibody different functional properties, such as the ability to activate the complement systemto bind to phagocytic cells, or to cross the placenta from mother to fetus. Am J Trop Med.

    2. Comparison of the amino acid sequences of different antibody molecules reveals a striking feature with important genetic implications. The diversity in the variable regions of both light and heavy chains is for the most part restricted to three small hypervariable regions in each chain; the remaining parts of the variable regionknown as framework regions, are relatively constant.
