Question #46547
The Question
A patient undergoing an allogeneic kidney transplant is administered a bioactive molecule produced by the fungus Trichoderma polysporum. If the patient concurrently harbors an undetected, early-stage malignant tumor, which of the following represents the most probable impact of this drug on the tumor's progression?
Options
- A.
Accelerated metastasis, as the drug suppresses Cell-Mediated Immunity (CMI), thereby facilitating the tumor's evasion of immunosurveillance.
- B.
Tumor regression, as the drug acts as a biological response modifier that activates cytotoxic T-cells to destroy malignant cells.
- C.
Unaltered tumor growth, because the drug selectively inhibits humoral immunity without affecting the T-lymphocytes responsible for tumor destruction.
- D.
Localized necrosis of the tumor, as the drug directly inhibits the rapid mitotic divisions characteristic of neoplastic cells.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: This question tests the synthesis of two distinct NCERT chapters ('Microbes in Human Welfare' and 'Human Health and Disease').
Students often memorize 'Cyclosporin A = organ transplant' without connecting its underlying mechanism (suppression of Cell-Mediated Immunity) to the other critical role of CMI: cancer immunosurveillance.
The trap lies in confusing immunosuppressants with biological response modifiers (like alpha-interferon) or assuming the drug only affects the transplanted organ.
