34. A 58-year-old man comes to the physician because of blood in his urine. He had a nephrectomy 10 years ago because of injuries sustained in a motor vehicle collision. Evaluation shows renal cell carcinoma in his remaining kidney and pulmonary metastases. Interleukin-2 (IL-2) therapy is started. Three weeks later, CT scan confirms regression of the tumor. Which of the following most likely caused the regression?
A) An effect of IL-2 on tumor vascularization
B) Cytotoxic effects of IL-2 on tumor cells
C) Increased natural killer cell activity
D) Induction of antitumor antibodies by IL-2
E) Induction of B-lymphocyte proliferation
F) Spontaneous remission

It is C. Used in therapy to activate lymphocytes and transfer back to patient (I think in melanoma). Cells are then called LAKs - lymphokine activated killer cells.
