Overview/Antigens/Types of Immunity (32.1-32.3)

Three major functions of _______ ____:
-Recognize anything foreign
-Defend from foreign material
-Remember the foreign invader

Adaptive immunity

The two types of adaptive immunity are

Humoral immunity
Cell-mediated immunity

Humoral immunity is mediated by (T/B) cells

B cells

Cell-mediated immunity is mediated by (T/B) cells

T cells

Humoral or cell-mediated?
B cells produce antibodies that directly target antigens of invaders

Humoral

Humoral or cell-mediated?
T cells control antibody production and can directly kill infected host cells

Cell-mediated 

Each antibody binds to a unique and specific antigen _____ on bacterial cells

eptiope

Self and non-self substances that may elicit an immune response

Antigens

Region of antigen to which a specific antibody binds

Antigen determinant sites (Epitopes)

An epitope that elicits an immune response is

immunogenic

What molecules can serve as antigens?

Any pieces (sugars, proteins, nucleic acids) that are released into the environment after lysing a bacterial cell

One antigen can have multiple

epitopes

What type of immunity?
Acquired through normal life experiences and is not induced through medical means

Natural

What type of immunity?
Produced purposefully through medical procedures (immunization)

Artificial

What type of immunity?
Consequences of a person developing their own immune response to a microbe

Active

What type of immunity?
Consequences of one person receiving preformed immunity made by another person

Passive

What kind of immunity would maternal antibodies be an example of?

Natural passive

What kind of immunity would vaccination be an example of?

Artificial active

What kind of immunity would an infection be an example of?

Natural active

What kind of immunity would immune globulin therapy be an example of?

Artificial passive
