Anti-Streptococcus antibodies found in the serum of a patient during a primary antibody response differ from the antibodies produced during a secondary response to the same antigen because of

Question

Quizplus · Accepted Answer

During a primary antibody response, the antibodies produced have low affinity and are less specific. However, during a secondary response, the antibodies are produced by memory B cells which have undergone affinity maturation, leading to an increase in both affinity and specificity of the antibodies. VDJ recombination is a process that occurs during B cell development and is not directly related to the production of different antibodies during a primary versus secondary response. Class switching involves the change in the isotype of the antibodies produced and is not directly related to the differences in antibodies produced during a primary versus secondary response. MHC processing and antigen adaptation are not directly related to the differences in antibodies produced during a primary versus secondary response.
