Specific Defenses of the Host: The Immune Response Innate(nonspecific) Defenses against any pathogen 。Immunity Specific antibody and lymphocyte response to an antigen 。Antigen(Ag) A substances that causes the body to produce specific antibodies or sensitized T cells ·Antibody(Ab) Proteins made in response to an antigen
Specific Defenses of the Host: The Immune Response • Innate (nonspecific) Defenses against any pathogen • Immunity Specific antibody and lymphocyte response to an antigen • Antigen (Ag) A substances that causes the body to produce specific antibodies or sensitized T cells • Antibody (Ab) Proteins made in response to an antigen
Terminology 。 Serology Study of reactions between antibodies and antigens 。Antiserum Generic term for serum because it contains Ab 。Globulins Serum proteins Gamma(y)globulin Serum fraction containing Ab

The Immune Response 。Acquired immunity Developed during an individual's lifetime 。Humoral immunity Involves Ab produced by B cells Cell-mediated immunity Involves T cells
The Immune Response • Acquired immunity Developed during an individual's lifetime • Humoral immunity Involves Ab produced by B cells • Cell-mediated immunity Involves T cells
