Immunology Final Exam: Questions And Answers(Pass!)
A vaccine is attempting to stimulate the adaptive immune system to create
memory. (slide 1:2)
a. true
b. false Right Ans - a. true
A vaccine is attempting to stimulate the adaptive immune system to create a
better innate response. (slide 1:2)
a. true
b. false Right Ans - b. false
*A vaccine is attempting to stimulate the adaptive immune system to create
MEMORY. However, we are just beginning to appreciate the role of the innate
immune system in this process.
In order to produce memory killer T cells which a vaccine, which of the
following is true? (slide 1:4)
a. Antigen must be presented in a secondary lymph organ
b. Antigen presenting cell must present antigen on MHC II
c. Infected cell must present antigen on MHC I
d. Infected cell must present antigen on MHC I Right Ans - c. Infected cell
must present antigen on MHC I
*The important point here is that memory B and helper T cells can be
produced efficiently even when no immune system cells have been infected by
the attacker
In order to produce memory B cells which a vaccine, which of the following is
true? (slide 1:4)
a. Antigen must be presented in a secondary lymph organ
b. Antigen presenting cell must present antigen on MHC II
,c. Infected cell must present antigen on MHC I
d. Infected cell must present antigen on MHC I Right Ans - a. Antigen must
be presented in a secondary lymph organ
*The important point here is that memory B and helper T cells can be
produced efficiently even when no immune system cells have been infected by
the attacker
In order to produce memory helper T cells which a vaccine, which of the
following is true? (slide 1:4)
a. Antigen must be presented in a secondary lymph organ
b. Antigen presenting cell must present antigen on MHC II
c. Infected cell must present antigen on MHC I
d. Infected cell must present antigen on MHC I Right Ans - b. Antigen
presenting cell must present antigen on MHC II
*The important point here is that memory B and helper T cells can be
produced efficiently even when no immune system cells have been infected by
the attacker
Most vaccines are believed to confer protection through what mechanism?
(slide 1:6)
a. Neutralizing antibodies
b. Specific compliment proteins
c. Microglia
d. Antigen presenting cells Right Ans - a. Neutralizing antibodies
In active immunization how can effectiveness be checked? (slide 1:6)
a. By using a skin scratch test
b. By analyzing T cell receptors against the cognate antigen
c. By measuring neutrophil levels in the blood
d. Checking antibody titers Right Ans - d. Checking antibody titers
*most vaccines are believed to confer protection through neutralizing
antibodies, which is the basis of using antibody titers to asses level of
protection
, In vaccination, both antibody and T cell responses seem to depend on the
innate immune system. (slide 1:6)
a. true
b. false Right Ans - a. true
In vaccination, both antibody and T cell responses seem to depend on the
acquired immune system. (slide 1:6)
a. true
b. false Right Ans - b. false
*In vaccination, both antibody and T cell responses seem to depend on the
INNATE immune system
Immunity acquired through passive immunotherapy is best described by what
statement? (slide 1:8)
a. Administration of an antigen so patient mounts a protective immune
response
b. Transfer of antibodies formed by immune individual or animal
c. A drug administered that actives B cells to produce antibodies against a
certain disease
d. Transfer of memory killer T cells against an antigen from one individual to
another Right Ans - b. Transfer of antibodies formed by immune individual
or animal
*this could occur mother to fetus e.g. via breast milk or injection of antisera
produced in horse or human
Transfer of preformed antibodies from mother to fetus can confer what type
of immunity? (slide 1:8)
a. Active
b. Passive
c. Permanent
d. No immunity is possible Right Ans - b. Passive
