Verified step by step guidance

Understand the primary antibody response: This is the body's initial response to an antigen, involving several key processes to build immunity.

Identify the role of B cells: During the primary antibody response, B cells are activated by antigens presented by dendritic cells.

Recognize the differentiation process: Activated B cells differentiate into plasma cells, which are responsible for producing antibodies.

Clarify the lag period: The lag period is the time between antigen exposure and the detectable production of antibodies. During this time, activation and differentiation occur.

Differentiate between memory cell proliferation and other processes: Memory cell proliferation typically occurs after the primary response, during the secondary response, when the body encounters the antigen again.
