The production of antibodies when body cells 1st encounter an antigen
Added by Michael P.
Step 1
Step 1: Antigen Recognition - When body cells first encounter an antigen (a foreign substance like a virus or bacteria), specialized immune cells called antigen-presenting cells (APCs) capture and process the antigen. Show more…

After the first exposure to an antigen, a primary adaptive immune response stimulates growth and multiplication of antigen-reactive cells.
Adi S.
As the plasma cells begin secreting antibody, the antibody begins to rise in concentration. When a person is exposed to an antigen for the first time, the immune reaction is called the primary response. The appearance of protective antibodies is delayed for 3-6 days while naive B cells multiply and differentiate.
Which antibody is produced first during an infection? What causes it to switch to a different type?
