question 9

Multiple Choice

You explain to your patient the role of the lymphocytes in her adaptive immune response. In the middle of your explanation, you are distracted and you tell her something that is NOT correct. Identify that statement.

• A) After activation, T lymphocytes divide and proliferate to form a population of helper T cells and a population of cytotoxic T cells; activated T cells secrete cytokines that exert an effect on other cells.
• B) After activation, B lymphocytes divide and proliferate to form a population of plasma cells and a population of memory cells; plasma cells produce antibodies that tag microbial invaders for elimination by phagocytes. 
• C) Once activated, helper T cells form a population of TH effector cells and a population of TH memory cells; TH effector cells produce cytokines that activate B cells and macrophages.
• D) Once activated, cytotoxic T cells form a population of TC effector cells and a population of TC memory cells; TC effector cells produce cytokines that induce apoptosis in virally infected self cells.
• E) Effector B cells and T cells express traits that help eliminate invaders in a primary response. Memory B cells and T cells are responsible for the effectiveness of the secondary response.
