Question

These are involved in cell mediated immunity.

• A. T-cells
• B. B-cells
• C. Interferons
• D. Interleukins

Hint:

Recognizing the role of T-cells is fundamental in understanding autoimmune diseases and in the development of vaccines.

Answer 1

The Correct Option is A

To solve the problem, we need to identify the cells involved in cell-mediated immunity.

1. Understanding Cell-Mediated Immunity:
Cell-mediated immunity involves T-cells, which are a type of white blood cell that helps in fighting infections and regulating immune responses. T-cells do not produce antibodies like B-cells but instead directly attack infected cells or help in activating other immune cells.

2. Analyzing the Options:
T-cells (Option 1): T-cells are indeed involved in cell-mediated immunity. They are essential for recognizing and responding to infected or cancerous cells.
B-cells (Option 2): B-cells are involved in humoral immunity, which involves the production of antibodies, not in cell-mediated immunity. 
Interferons (Option 3): Interferons are signaling proteins that help in immune responses, especially in antiviral defense, but they are not directly responsible for cell-mediated immunity.
Interleukins (Option 4): Interleukins are cytokines that help in communication between immune cells, but they are not the primary players in cell-mediated immunity, although they can aid in T-cell function.

3. Conclusion:
Based on the understanding of cell-mediated immunity, the correct answer is:

Final Answer:
The correct option is (A) T-cells.
