Question

The decrease in the T-Lymphocytes count in human blood will finally result in

• A. decrease in antigens
• B. decrease in antibodies
• C. increase in antibodies
• D. increase in antigens

Hint:

T-lymphocytes are essential for activating B-cells, which in turn produce antibodies. A decrease in T-cells leads to reduced antibody production, impairing the immune response.

Answer 1

The Correct Option is B

Step 1: Understanding the role of T-lymphocytes: - T-lymphocytes (T-cells) play a crucial role in the immune response by recognizing and attacking infected cells, as well as coordinating the immune system.
- They are essential for the production and regulation of antibodies by activating other immune cells, such as B-cells, which are responsible for antibody production.
Step 2: Effects of a decrease in T-lymphocyte count:
- A decrease in the T-lymphocyte count results in impaired immune response because fewer T-cells are available to activate B-cells.
- Without sufficient activation, B-cells will produce fewer antibodies.
Step 3: Conclusion:
The decrease in T-lymphocyte count will lead to a decrease in antibody production, not an increase. This results in a weakened immune response.
Thus, the correct answer is option (B).
