Question #47682
The Question
Read the following statements regarding a bioactive molecule routinely administered to patients following a renal allograft: I. It is commercially produced via the fermentation activity of the fungus Trichoderma polysporum. II. It primarily suppresses the humoral immune response to prevent antibody-mediated destruction of the graft. III. Its prolonged administration paradoxically increases the patient's susceptibility to opportunistic pathogens. IV. It acts by inhibiting the activation of T-lymphocytes, thereby dampening cell-mediated immunity. Which of the above statements are CORRECT?

I, III, and IV
- B.
I, II, and III
- C.
I and IV only

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Students often memorize 'immunosuppressant' without linking it to the specific branch of the immune system (Cell-Mediated Immunity via T-cells) responsible for allograft rejection.
The trap lies in Statement II, which incorrectly attributes graft rejection prevention to the suppression of humoral (B-cell/antibody) immunity.
