A) The effector helper T cell binds to an antigen-presenting dendritic cell.
B) The effector helper T cell binds to a memory T cell.
C) The effector helper T cell binds to a complement protein.
D) The effector helper T cell binds to MHC-antigen complexes on B cells.
E) Any of these can stimulate cytokine production.

Question

Quizplus · Accepted Answer

Effector helper T cells release cytokines when they bind to MHC-antigen complexes on B cells. This interaction is important for activating B cells and promoting antibody production. Binding to antigen-presenting dendritic cells or memory T cells may also occur, but it is the binding to MHC-antigen complexes on B cells that specifically triggers cytokine release. Binding to complement proteins is not a known trigger for cytokine release by effector helper T cells.
