Specific Immune Response Reflection Questions
1. Explain the task of each type of cell:
a. Macrophage cells
b. B-cells
c. Cytotoxic T-cells
d. Helper T-cells
2. The first line of defense is considered a general or nonspecific form of immune system response. Would you call the
role played by macrophage cells nonspecific or specific? Defend your response.
3. How are B-cells and T-cells similar? How are they different?
4. How are cytotoxic T-cells and helper T-cells similar? How are they different?
5. Explain why B-cell response is called ―antibody-mediated‖ while T-cell response is called ―cell-mediated‖?

6. What does it mean to be an APC? Which cells can be APCs? What is the purpose of an APC?
7. Only vertebrates have a specific immune response (the response seen with T-cells and B-cells). Explain how specific
immunity is an advantage over non-specific immune response.
8. Give one example of cell signaling from each of the following: the second line of defense, an antibody-mediated
response, and a cell-mediated response.
9. Explain how the human body would respond to each of the following:
a. A vaccination for a bacterial illness
b. A second exposure to the chicken pox
c. A transplanted organ
d. Exposure to a lysogenic virus
e. The presence of a cancerous tumor

10. The diversity in the family of genes called the human leukocyte antigen (HLA) system determines what range of
epitopes can be detected by white blood cells. Some of the HLA genes have as many as 100 different possible alleles
for a particular gene locus, each of which can produce a different type of antibody. How do you think the diversity of this
group of genes plays a role in natural selection?
11. How do you think immune response affects the evolution of living pathogens such as bacteria or viruses?
