Textbook Question
Chapter 43, Problem 18TYK
What is the key advantage to the use of monoclonal antibodies as medicines?
- a. Because we already have antibodies in our blood these molecules are not recognized as foreign.
- b. They are specific for a single antigen, or even for a specific epitope on an antigen.
- c. Because they are produced by living cells, they are more natural and healthful than artificially synthesized drugs.
- d. They are inexpensive to produce, so they can be widely distributed.

Which DOES NOT describe monoclonal antibodies?
Group of answer choices
a. Monoclonal antibodies are produced in test tubes by hybridoma cells
b. Monoclonal antibodies are specific to multiple antigens
c. These antibodies are used in diagnostic tests
d. The antibody producing cells may come from a non-human source
Antibodies against a specific antigen can be injected into a person to provide passive immunity. For which reason is this NOT as effective as the process of vaccination with that antigen?
Select one:
a.
Injection of antibodies may cause allergic reactions, while vaccination never causes allergic reactions.
b.
Injection of antibodies does not provide long-lasting immunity, and vaccination with antigens triggers a clonal selection of B cells and cytotoxic T cells.
c.
Vaccination with antigens triggers a clonal selection of B cells and cytotoxic T cells.
d.
Injection of antibodies does not provide long-lasting immunity.
e.
Injection of antibodies does not provide long-lasting immunity and may cause allergic reactions, while vaccination never causes allergic reactions.
A researcher discovers that a breed of rabbits have antibodies that can neutralize HIV. The researcher decides to extract the antibody concentrated plasma and deliver it to a patient with HIV. What would you likely expect to see?
a. The HIV patient will now have a fighting chance to eliminate HIV as the antibodies will not discriminate and bind to the same viral antigenic determinants.
b. The HIV patient will form antibodies against the rabbit serum antibodies.
c. The rabbit antibodies will opsonize the HIV antigenic determinants on the MHC II.
d. The rabbit antibodies will never work because HIV in humans are different than HIV in rabbits.

- Biologists can develop antibodies against nerve growth factor (i.e., molecules that inactivate nerve growth factor). What would happen if someone injected such antibodies into a developing nervous system?arrow_forwardExplain why each choice (a-d) is correct or incorrect. Allergens differ from antigens because a. Allergens produce an abnormally large immune response to what is an otherwise harmless particle. b. Allergens do not involve the leucocytes, they simple stimulate the inflammatory response. c. Allergens are only active seasonally and are generally harmless to the body. d. Allergens are primarily plant derived while antigens are bacterial or viral in nature.arrow_forwardSuppose a person recovers normally from viral infections, but then gets the same viral infections over and over again- unlike the rest of us. A. What is probably wrong –B cells, helper T cells and/or cytotoxic T cells? B. Should this person be at a higher risk of cancer than the rest of us? C. Should this person be able to lyse bacterial cells as well as the rest of us? D. Should this person tolerate a graft (from an unreated person) better than you are me?arrow_forward
