Binding of _____ to _____ induces T-cell proliferation and differentiation of activated T cells.

Question

Quizplus · Accepted Answer

Binding of IL-2 to the high-affinity IL-2 receptor induces T-cell proliferation and differentiation of activated T cells. The low-affinity IL-2 receptor binds IL-2 with lower affinity and is involved in regulating the availability of IL-2 in the immune system. Choice A is incorrect because binding of CD4 to MHC class II is involved in antigen recognition and activation of T cells, not in T-cell proliferation or differentiation. Choice B is incorrect because CD28 on T cells binds to B7 on antigen-presenting cells to provide a co-stimulatory signal for T-cell activation, but it is not directly involved in T-cell proliferation or differentiation. Choice C is incorrect because LFA-1 and ICAM-1 are involved in T-cell adhesion and migration, but not in T-cell proliferation or differentiation. Choice E is incorrect because the low-affinity IL-2 receptor does not induce T-cell proliferation and differentiation directly.
