Verified step by step guidance

Understand the concept of cell-mediated immunity: Cell-mediated immunity is a type of immune response that does not involve antibodies but rather the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen.

Identify the role of T lymphocytes: T lymphocytes, or T cells, are a type of white blood cell that play a central role in cell-mediated immunity. They are responsible for directly attacking infected cells and coordinating the immune response.

Differentiate between B lymphocytes and T lymphocytes: B lymphocytes, or B cells, are primarily involved in humoral immunity, which involves the production of antibodies. In contrast, T lymphocytes are involved in cell-mediated immunity.

Consider the role of erythrocytes: Erythrocytes, or red blood cells, are not involved in the immune response. Their primary function is to transport oxygen and carbon dioxide in the blood.

Evaluate the role of macrophages: Macrophages are involved in both innate and adaptive immunity. They can present antigens to T cells and are involved in the activation of T lymphocytes, but they are not the primary cells responsible for cell-mediated immunity.
