Describe what happens when Antigen binds to the receptor on B cells?
Describe what happens when Antigen binds to the receptor on B cells? The B cell will proliferate (undergo several divisions to make many clones of itself These cells will then differentiate into plasma cells or memory cells The plasma cells will secrete antibody The memory cells allow for a rapid secondary immune response
