Verified step by step guidance

Understand the concept of cell-mediated immunity: It 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 the types of immune cells: Neutrophils are primarily involved in the innate immune response and are the first responders to infection. Macrophages are also part of the innate immune system and help in phagocytosis and antigen presentation. B lymphocytes are responsible for humoral immunity, which involves the production of antibodies.

Recognize the specific function of T lymphocytes in cell-mediated immunity: T lymphocytes include various subtypes such as helper T cells, cytotoxic T cells, and regulatory T cells, each with specific roles in identifying and destroying infected cells.

Conclude that T lymphocytes are the primary cells responsible for cell-mediated immunity, as they directly interact with infected cells and coordinate the immune response without the use of antibodies.
