Final answer:
Helper T cells, also known as TH cells, produce different types of interleukins depending on whether they are TH1 or TH2 cells.
Step-by-step explanation:
Helper T cells, also known as TH cells, are a type of immune cell that produce cytokines to enhance other immune responses. They are classified into two classes, TH1 and TH2, based on the cytokines they secrete. TH1 cells secrete cytokines that enhance the activities of macrophages and other T cells, while TH2 cells stimulate B cells to secrete antibodies. Therefore, the type of interleukin produced by helper T cells depends on whether they are TH1 or TH2 cells.
