Verified step by step guidance

Understand the role of T cells in the immune system: T cells are a type of lymphocyte that play a central role in cell-mediated immunity. They do not produce antibodies but instead directly attack infected cells.

Differentiate between T cells and B cells: B cells are responsible for humoral immunity, which involves the production of antibodies. In contrast, T cells are involved in cell-mediated immunity, where they directly attack and destroy infected cells.

Clarify the role of antibodies: Antibodies are produced by B cells and are the main effectors in humoral immunity, not cell-mediated immunity. Therefore, they are not the primary effectors in the cell-mediated immune response.

Explain antigen presentation: The cell-mediated immune response is dependent on antigen presentation. Antigen-presenting cells (APCs) display antigens to T cells, which is crucial for the activation of T cells and the subsequent immune response.

Identify the correct statement: Based on the understanding of T cells, B cells, antibodies, and antigen presentation, recognize that the statement 'T cells are primarily responsible for the cell-mediated immune response' is true.
