Text Solution

Verified by Experts

The correct Answer is:
A

Cyclosporin A is cyclic oligipeptide obtained through fermentative activity of fungus Trichoderma polysporum. It has immunosuppressive properties and inhibits activation of T-cells. T cells of immune system mainly function to kill non-self cells. Because cyclosporin A inhibits T cell function, it caused immunosuppression and chances of rejection of transplanted organ are reduced. Thus, organ transplant patients are provided with cyclosporin A.
