Verified step by step guidance

Understand the concept of the cell-mediated immune response, which is a type of immune response that does not involve antibodies but rather the activation of phagocytes and various types of T cells.

Identify the key players in the cell-mediated immune response. The primary cells involved are T lymphocytes, which include helper T cells (CD4+), cytotoxic T cells (CD8+), and regulatory T cells.

Differentiate between the roles of T lymphocytes and other immune cells. T lymphocytes are responsible for directly attacking infected cells and coordinating the immune response, whereas B lymphocytes are primarily involved in the humoral immune response by producing antibodies.

Consider the role of macrophages in the immune response. While macrophages are important for phagocytosis and antigen presentation, they are not the primary cells in the cell-mediated immune response.

Conclude that T lymphocytes are the most involved in the cell-mediated immune response, as they are crucial for recognizing and responding to infected or abnormal cells.
