Cytotoxic T cells are primarily involved in ____________.

• A. Innate Immunity.
• B. Antibody production.
• C. Cell-mediated Immunity.
• D. Humoral Immunity.

Answer: (C)

Verified step by step guidance

1. Understand the role of cytotoxic T cells in the immune system. Cytotoxic T cells, also known as CD8+ T cells, are a type of lymphocyte that play a crucial role in the adaptive immune response.
2. Differentiate between the types of immunity: Innate immunity is the body's first line of defense and is non-specific, while adaptive immunity is specific and involves lymphocytes such as T cells and B cells.
3. Recognize that cell-mediated immunity is a branch of adaptive immunity that does not involve antibodies. Instead, it relies on the activation of phagocytes and the release of various cytokines in response to an antigen.
4. Identify the specific function of cytotoxic T cells within cell-mediated immunity. These cells are responsible for directly killing infected host cells, cancer cells, and sometimes foreign cells.
5. Conclude that cytotoxic T cells are primarily involved in cell-mediated immunity, as they directly attack and destroy infected or abnormal cells without the involvement of antibodies.
