LEARNING OBJECTIVES

After reading this chapter, you should be able to:

• Identify a lymphocyte based on its morphology.
• Understand the differences between T cells, B cells, and NK cells.
• Understand how lymphocyte populations can be characterized based on their

cell surface molecules.
• Recognize that cell surface molecules are classified by the cluster of
differentiation (CD) system.

• Understand that lymphocytes express antigen receptor complexes consisting of
antigen-binding and signal-transducing components.
• Describe the characteristic features of T and B cells.

• Explain that lymphocytes also possess receptors for cytokines, immunoglobulins,
and complement.
• Define cell phenotypes and explain how they are determined.

• List the major antibody-binding receptors expressed on lymphocytes.
• List some cell-adhesion molecules expressed on lymphocytes and understand
their functions.

• Understand how mitogens can be used to determine lymphocyte functionality.
• Define mitogen, lymphocyte, T cell, B cell, innate lymphoid cells,
phytohemagglutinin, concanavalin A, TCR, and BCR.

Lymphocytes are the cells responsible for adaptive immune
