E)All of these choices are correct.

Question

Quizplus · Accepted Answer

The T-cell response to T-cell-dependent antigens requires a protein antigen for processing and presentation by antigen-presenting cells (APCs), which have Class II MHC receptors that interact with the T-cell receptor. The T-cell receptor also binds to a specific site on the antigen, leading to activation of T-helper cells that secrete interleukin-1, which activates other immune cells. Therefore, all of these choices are correct.
