The Adaptive Immune System: The Steps Involved in Adaptive Immune Respomses

Learning Objectives for "The Adaptive Immune System: The Steps Involved In Adaptive Immune Responses"

After completing this section you should be able to perform the following objectives.

1. List the 5 general steps involved in the immune responses in their correct order.

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

a. the blood
b. tissues
c. the respiratory tract
d. the gastrointestinal tract
e. the genitourinary tract

3. Briefly describe how the receptor molecules on the surface of naive B-lymphocytes, T4-helper lymphocytes, and T8-lymphocytes eventually recognize or bind epitope, indicating the roles of BCR, TCR, CD4, CD8, MHC-I, and MHC-II molecules in lymphocyte activation.

4. State the overall function of T4-helper lymphocytes and the importance behind rapid proliferation of activated lymphocytes.

5. State what types of effector cells the proliferating B-lymphocytes and T8-lymphocytes differentiate into in order to destroy or neutralize the antigen.

6. Define cytokine.

7. State the function of memory cells.

8. State what is meant by immunologic tolerance.
