A student states, "It seems like helper T cells do a lot more than just 'help' the cellular immunity process." Which of the following responses listed below best conveys an aspect of the role of CD4+ helper T cells in immunity?
A)
"Without helper T cells, no antigens would be presented."
B)
"Helper T cells play a major role in stimulating and regulating the whole process."
C)
"Without helper T cells, the wrong antibodies would end up being produced."
D)
"Helper T cells are key to the hematopoiesis that produces all the components of the immune system."
Ans:
B
Feedback:
Helper T cells are central to the regulation, proliferation, and stimulation of the immune system. They do not play a central role in antigen presentation or early hematopoiesis, however. Their absence would not result in incorrect antibody production, but rather insufficient or absent immune response.
