Question

Patients who have undergone organ transplants are given anti-rejection medications to

• A. Minimize infection
• B. Stimulate B-macrophage cell interaction
• C. Prevent T-lymphocyte proliferation
• D. Adopt the $HLA$ of donor

Answer 1

Answer: (C)

Prevent T-lymphocyte proliferation

• The drugs that lower the immune system' are called immunosuppressants.
• These drugs are given to prevent graft rejection by lowering the immune system's ability to reject the transplanted organ.
• If immunity is not lowered the T lymphocytes which are the components of cell-mediated immunity destroy the transplanted tissue causing graft rejection. Thus the correct answer is option C.
