A) antigen binding and antibody production
B) antigen binding and co-stimulation
C) antigen binding, antibody production, and co-stimulation
D) antibody production and co-stimulation

Question

Quizplus · Accepted Answer

T-cell activation requires antigen binding to the T-cell receptor, as well as co-stimulation from a co-stimulatory molecule on the antigen-presenting cell. Antibody production is not directly involved in T-cell activation, although antibodies can be produced by B-cells in response to T-cell activation. Therefore, choice B, antigen binding and co-stimulation, is the best choice.
