A helper T cell that secretes ______ induces a switch in the adjacent B cell from IgM synthesis to one of the IgG classes.
A)IFN-$\alpha$
B)IFN-$\gamma$
C)IFN-$\beta$
D)interleukin-1
E)glucagons

Question

Quizplus · Accepted Answer

Helper T cells secrete cytokines, including IFN-γ, that can induce a switch in the adjacent B cell from IgM synthesis to one of the IgG classes. Therefore, choice B, IFN-γ, is the best answer. Interleukin-1 does not induce a switch in antibody class, and glucagons are not involved in the immune response. Choices A and C list a nonspecific cytokine and an unrelated molecule, respectively.
