Abnormal T cell response results in delayed hypersensitivity with the secretion of
A)histamine.
B)lymphokines.
C)interleukin.
D)antibodies.

Question

Quizplus · Accepted Answer

Delayed hypersensitivity is a type IV hypersensitivity reaction that involves T cells. During this type of reaction, T cells secrete lymphokines, which recruit other immune cells to the site of the antigen and cause tissue damage. Histamine is typically associated with immediate hypersensitivity reactions (type I), which involve the activation of IgE antibodies and mast cells. Interleukins are also produced by T cells during immune responses, but they are not as directly involved in delayed hypersensitivity reactions as lymphokines. Antibodies are produced by B cells, not T cells. Therefore, the best choice to complete the statement is B: lymphokines.
