MIC 412LEC JAC: Fundamentals of Immunology (Winter 24)

Professor Amy Jacobs

University: University at Buffalo

Chapter 1 Quiz: Attempt 1- Score 100% (Highest Score)

Question 1: In addition to T cells, which cell type is required for initiation of all T cell–mediated immune responses?

 a. Effector cells  b. Memory cells  c. Natural killer cells  d. Antigen-presenting cells  e. B lymphocytes  Correct Answer: d. Antigen-presenting cells

Question 2: Which of the following cell types is required for all humoral immune responses?

 a. Natural killer cells  b. Dendritic cells  c. Cytolytic T lymphocytes  d. B lymphocytes  e. Helper T lymphocytes

Correct Answer: d. B lymphocytes

Question 3: A previously healthy 8 - year-old boy is infected with an upper respiratory tract virus for the first time. During the first few hours of infection, which one of the following events occurs?

 a. The adaptive immune system responds rapidly to the virus and keeps the viral infection under control.  b. The innate immune system responds rapidly to the viral infection and keeps the viral infection under control.  c. Passive immunity mediated by maternal antibodies limits the spread of infection.  d. B and T lymphocytes recognize the virus and stimulate the innate immune response.  e. The virus causes malignant transformation of respiratory mucosal epithelial cells, and the malignant cells are recognized by the adaptive immune system.  Correct Answer: b. The innate immune system responds rapidly to the viral infection and keeps the viral infection under control.

Question 4: Antibodies and T lymphocytes are the respective mediators of which two types of immunity?

 a. Specific and nonspecific  b. Humoral and cell-mediated  c. Passive and active

Question 7: Which of the following best describes clonal expansion in adaptive immune responses?

 a. Increased number of different lymphocyte clones, each clone specific for a different antigen during the course of an infection  b. Increased number of different lymphocyte clones, each clone specific for a different antigen during development of the immune system, before exposure to antigen  c. Increased number of lymphocytes with identical specificities, all derived from a single lymphocyte due to nonspecific stimuli from the innate immune system  d. Increased number of lymphocytes with identical specificities, all derived from a single lymphocyte stimulated by a single antigen  e. Increased size of the lymphocytes of a single clone due to antigen-induced activation of the cells  Correct Answer: d. Increased number of lymphocytes with identical specificities, all derived from a single lymphocyte stimulated by a single antigen

Question 8: Which of the following is a unique property of the adaptive immune system?

 a. Highly diverse repertoire of specificities for antigens  b. Self-nonself discrimination  c. Recognition of microbial structures by both cell-associated and soluble receptors  d. Protection against viral infections

 e. Responses that have the same kinetics and magnitude on repeated exposure to the same microbe  Correct Answer: a. Highly diverse repertoire of specificities for antigens

Question 9: B cells mature in the

 a. bone marrow  b. thymus  c. liver  d. brain  e. pancreas  Correct Answer: a. bone marrow

Question 10: The principal function of the immune system is:

 a. defense against cancer  b. repair of injured tissues  c. defense against microbial infections  d. prevention of inflammatory diseases  e. protection against environmental toxins  Correct Answer: c. defense against microbial infections
