What is the primary goal of immunosuppressive therapy in transplantation?

• A. To achieve graft acceptance without severely compromising the immune system
• B. To completely suppress the immune system
• C. To enhance immune rejection
• D. To promote autoimmune disease

Answer: (A)

The main idea is to prevent the immune system from attacking the transplanted organ while keeping enough immune function to defend against infections and cancer. Immunosuppressive therapy aims to dampen the T-cell responses that drive graft rejection, achieving a state where the graft is accepted or tolerated without leaving the patient profoundly immunocompromised. The goal is a careful balance: enough suppression to prevent rejection, but not so much that infections or malignancies take hold. That’s why complete immune shutdown is undesirable, and why we don’t aim to enhance rejection or promote autoimmune disease. In practice, drugs block T-cell activation and proliferation, reduce cytokine signals, and limit immune cell expansion to protect the graft while preserving general immune defense.
