A) "Humoral immunity does not involve helper T cells in the immune response."
B) "Humoral immunity does not have a role in hypersensitivity reactions."
C) "Humoral immunity requires cytolytic T cells that attack antigens directly."
D) "Humoral immunity uses cells produced by B lymphocytes in the immune response."

Question

Quizplus · Accepted Answer

Humoral immunity refers to immunity mediated by antibodies, which are produced by B lymphocytes. Helper T cells have an essential role in antibody production by B cells. The antibody immunoglobulin E plays a role in hypersensitivity reactions. Cytolytic T cells do not produce antibodies; they are key players in cellular immunity.
