Humoral Immunity

B cells bind to antigens forming APCs.

Cloned T cells bind with B APCs.

Clonal Selection occurs. This is where a B cell is selected to B cloned as it has the correct antibody.

Interleukins produced by cloned T cells activate B cells.

B cells undergo mitosis (clonal expansion) forming plasma and memory cells.

Plasma cells are involved in the primary response. These produce antibodies.

B memory cells divide to form plasma cells during the secondary response. This makes it much quicker.
