TYPES OF IMMUNITY
Immunity an organism is born with
What is innate (genetic) immunity?
Molecules that provoke a specific immune response are called these
What are antigens?
This immunoglobulin class makes up about 80% of serum antibodies
What is IgG?
These activated B cells actively secrete antibodies
What are plasma cells?
These T cells are usually CD4+ and help activate B cells and macrophages
What are helper T cells?
Immunity developed during life after infection or vaccination
What is acquired immunity?
The small region of an antigen recognized by an antibody is called this
What is an epitope?
This immunoglobulin is the first antibody produced during infection
What is IgM?
This process destroys self-reactive B and T cells during development
What is clonal deletion?
These T cells destroy infected host cells
What are cytotoxic T cells?
Antibodies passing from mother to fetus is this type of immunity
What is naturally acquired passive immunity?
The site of antibodies that allow antigens to bind
What is antigen binding site?
This antibody class is found in tears, saliva, milk, and mucosal secretions
What is IgA?
The process in which antigen stimulates B cells to proliferate is called this
What is clonal selection?
These are the chemical messengers that stimulate immune response
What are cytokines?
Going yearly for a flu vaccine indicates this type of immunity
What is artificially acquired active immunity?
Antigens are composed of these two macromolecules
What are proteins and carbs?
This antibody class is associated with allergic reactions and mast cells
What is IgE?
Cells that can be used for future infections
What are T helper cells?
Your body does not produce these antibodies naturally; rather, they are given directly
What is artificially acquired passive immunity?
The shape of antibodies and their number of chains (heavy and light)
What are monomers, and 2?
This immunoglobulin class functions mainly as a B-cell receptor and makes up only 0.2% of serum antibodies
What is IgD?
The response that allows an increased antibody response
What is the secondary response?
Tc cells undergo this in order to prevent unwanted immune response
