Exam 15: Host Defenses II: Specific Immunity and Immunization

The structural and functional differences that distinguish immunoglobulin isotypes are due to variations associated with their Fc fragments.

Which process involves a more rapid synthesis and greatly increased titer of antibody when the immune system is subsequently exposed to the same antigen?

Lymphocytes

The adaptive immune system is complex, but it can be summarized in four consecutive stages: i) lymphocyte encounter with an immunogen, ii) development of lymphocyte specificity against that immunogen, iii) 2nd encounter with the immunogen, and iv) development of memory cells.

Destruction of lymphocytes with self-specificity is called ______.
