    A model for the enhancement of the primary humoral immune response of rhesus monkeys to marginal or weakly antigenic vaccines is presented. Our procedure used the complexing of formalin-inactivated Venezuelan equine encephalomyelitis (VEE) virus vaccine with specific, homologous, immune gamma globulin (IgG) at equivalence. Equivalence was determined by combining the concentrated, isotopically labeled ((3)H) virus with various concentrations of specific Sephadex-fractionated IgG. Enhancement of VEE virus antibody response in monkeys was obtained from preparations containing a marginal concentration of antigen that was complexed at equivalence with homologous IgG as compared with antigen alone. Protection in Swiss mice closely paralleled the antibody response pattern observed in monkeys, since complexes at equivalence provided 30 to 50% greater protection against challenge than antigen alone.

    Antibody Structure

    Overview
    Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

    Antigens Involved in Adaptive Immunity

    An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

    Complete antigens possess both immunogenicity and reactivity.
    Antibody Actions01:26

    Antibody Actions

    Antibodies, or immunoglobulins, are critical players in the immune system's arsenal against invading pathogens. Produced by B cells and plasma cells, their primary role is to detect and bind to specific antigens, molecules found on the surface of pathogens like bacteria or viruses. Beyond antigen recognition, antibodies perform several vital functions that contribute to immune defense.
    Neutralization
    Antibodies can bind to pathogens, preventing them from infecting host cells. This process...
    Hypersensitivity Reactions: Immune-Complex Reactions01:19

    Hypersensitivity Reactions: Immune-Complex Reactions

    Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
