|
Is vaccination an example of innate or adaptive immunity?
|
Adaptive (Induced resistance to a specific pathogen)
|
|
|
How was basic research on chicken diseases related to the discoveries of both humoral and cellular immunity?
|
Humoral: immunity brought on by antibodies (B cells recognize antigens)
Cellular: T cells secrete cytokines |
|
|
Does an antibody necessarily react with a bacterium as an antigen or as an epitope?
|
Antibodies react with the epitopes on the antigen
|
|
|
The original theoretical concepts of an antibody called for a rod with antigenic determinants at each end. What is the primary advantage of the Y-shaped structure that eventually emerged?
|
Y is flexible and can assume a T shape
|
|
|
Which class of antibody is most likely to protect you from a common cold?
|
IgA
|
|
|
Would pneumococcal pneumonia require a T-helper cell to stimulate a B cell to form antibodies?
|
T-dependent antigens, mainly proteins such as those found on viruses, bacteria, foreign RBCs, and haptens with their carrier molecules

|
|
Plasma cells produce antibodies; do they also produce memory cells?
|
Ask??
|
|
|
In what way does a B cell that encounters an antigen function as an antigen-presenting cell?
|
Ask??
|
|
|
On what part of the antibody molecule do we find the amino acid sequence that makes the huge genetic diversity of antibody production possible?
|
The variable (V) region
|
|
|
Antibodies and what other component of the immune system are required for the lysis of a target antigenic cell?
