Final answer:
Helper T cells are a type of lymphocyte that release cytokines to activate or control other lymphocytes. The normal ratio of helper cells to suppressor cells is around 2:1 or 3:1.
Step-by-step explanation:
Helper T cells are a type of lymphocyte that play a crucial role in the immune response. They release cytokines, which activate or control the activities of other lymphocytes. The normal ratio of helper cells (CD4+ T cells) to suppressor cells (CD8+ T cells) in a healthy person is around 2:1 or 3:1. However, this ratio can vary in certain diseases or conditions.
