Question

Which of the following statements about stimulated lymphocytes is correct?

Options

• A stimulated lymphocyte produces many types of cells, including both effector cells and memory cells

• A stimulated lymphocyte produces only antibodies

• A stimulated lymphocyte does not divide or differentiate into other cell types

• A stimulated lymphocyte produces only memory cells that remain active

Answer 1

When a lymphocyte is stimulated by an antigen, it undergoes clonal expansion and differentiation, producing many types of cells. These include sensitised lymphocytes or effector cells that immediately fight the specific antigen and some cells that become memory cells for long-term immune protection.
