Patients Who Have Received an Organ Transplant Take an Immunosuppressant

Patients who have received an organ transplant take an immunosuppressant called cyclosporine to:

A) encourage the patient's T cells to recognize the new organ cells as "self".
B) upregulate T-regulatory cells to prevent any immune response against the new organ.
C) prevent clonal expansion through inhibition of IL-2 transcription.
D) inhibit calcineurin which results in less NFAT phosphorylation.
