Your friend asks you how her B cells "know" when to make antibodies. You tell her that B cells must become activated, and that she has another type of cell that assists in this. These are the
A) TH cells that bind to the B cell and release cytokines that activate that B cell.
B) TC cells that bind to the B cell and release cytokines that activate that B cell.
C) TH cells that bind to the B cell and release cytokines that activate that T cell.
D) TC cells that bind to the B cell and release cytokines that activate that T cell.
E) TH cells that present the antigen to the B cell, leading to activation of that B cell.

Quizplus · Accepted Answer

TH cells bind to the B cell and release cytokines that activate that B cell, initiating the process of antibody production. These activated B cells differentiate into plasma cells, which secrete large amounts of antibodies against the specific antigen. TC cells do not play a direct role in B cell activation, and presenting the antigen to the B cell is not the same as activating it.
