Question

Quizplus · Accepted Answer

Helper T cells play a crucial role in the activation of the adaptive immune response by interacting with antigen-presenting cells and activating other immune cells, such as B cells and cytotoxic T cells. Therefore, option A is the correct choice. Option B is incorrect since Helper T cells often function to enhance the immune response. Option C is incorrect since it describes the function of cytotoxic T cells, not helper T cells. Option D is incorrect since B7 proteins are actually released by antigen-presenting cells, not helper T cells.
