Neither of them is wrong.

Yes! Good going. Actually, neither of the doctors is wrong. B-cells and T-cells have joint custody over antibodies. Helper Ts make it possible for the B lymphocytes to produce antibodies and, in turn, the Suppressor Ts help control the amount of antibodies in the body. Because both cell types have control over this aspect of the immune system, it is extremely important the lymphocytes work together, as a team, to produce the proper immune responses.

Great, well let's give our doctors a chance to get their last ideas in.
