When an antigen is bound to a Class II MHC protein,it can activate a(n)________ cell.
A)plasma

C)NK
D)suppressor T
E)cytotoxic T

Question

Quizplus · Accepted Answer

CD4 T cells are known as helper T cells and are activated by antigens bound to Class II MHC molecules. They play a crucial role in the immune response by releasing cytokines that activate other immune cells. Plasma cells (A) are not directly activated by antigens bound to MHC molecules. NK cells (C) do not require MHC molecules for activation. Suppressor T cells (D) are not activated by antigens bound to MHC molecules. Cytotoxic T cells (E) are activated by antigens bound to Class I MHC molecules, not Class II MHC molecules.
