Antibodies:
5 major types of antibodies (immunoglobulins) constitute the gamma globulin fraction of the plasma (IgG, IgA, IgM, IgE, IgD)
Antibody Actions:
3 methods by which antibodies react to antigens:
• Direct attack by agglutination, precipitation, or neutralization of
antigens; these methods make antigens more susceptible to phagocytosis
• Activation of complement results in opsonization, chemotaxis,
inflammation, agglutination, neutralization, alteration, or lysis
of antigens or antigen-bearing cells
• Inflammation: Stimulation of local inflammatory changes in the
area, that helps prevent the spread of the pathogens
