Self Quiz for The Adaptive Immune System:The Steps Involved in Adaptive Immune Responses

Study the material in this section and then write out the answers to these questions.
Do not just click on the answers and write them out. This will not test your understanding of this tutorial.

1. State where antigens may encounter APCs, B-lymphocytes, and T-lymphocytes if they enter the following:

a. the blood (ans)

b. tissues (ans)

c. the respiratory tract (ans)

d. the gastrointestinal tract (ans)

e. the genitourinary tract (ans)

 

2. Match the following:

_____ Use lysosomes to degrade exogenous antigens into peptides, bind them to MHC-II molecules, and present them to naive T4-lymphocytes. (ans)

_____ Uses BCR to recognize epitopes of antigens; a few antigens are recognized by toll-like receptors. (ans)

_____ Uses TCR and CD4 to recognize peptide epitopes from exogenous antigens bound to MHC-II molecules of antigen-presenting dendritic cells, macrophages, and B-lymphocytes. (ans)

_____ Uses TCR and CD8 to recognize peptide epitopes from endogenous antigens bound to MHC-I molecules of cells. (ans)

_____ Cells that allow for a heightened secondary response upon subsequent exposure to the same antigen. (ans)

_____ Once activated itself, secretes cytokines that enable activated B-lymphocytes and T-lymphocytes to proliferate and differentiate. (ans)

_____ Use proteasomes to degrade endogenous antigens into peptides, bind them to MHC-I molecules, and present them to naive T8-lymphocytes. (ans)

_____ Differentiate into antibody secreting plasma cells. (ans)

_____ Differentiate into cytotoxic T-lymphocytes (CTLs). (ans)

a. T4-lymphocytes
b. T8-lymphocytes
c. dendritic cells
d. B-lymphocytes
e. memory cells

3. State the overall function of T4-effector lymphocytes and the importance behind rapid proliferation of activated lymphocytes. (ans)

4. The ability of the body to initiate and direct adaptive immune responses against antigenic molecules foreign to the body but not against antigenic molecules that are a normal component of the body is called ____________________________. (ans)

5. Multiple Choice (ans)
