The immunostimulator LS-2616 abolishes the effect of cyclosporin A in a rat cardiac transplantation model. The present paper compares the characteristics of rejection obtained under different immunosuppressive regimens with and without additional LS-2616 application in the same model. Cyclosporin A (CyA, 10 mg/kg daily), prednisolone (15 mg/kg daily), or 15-deoxyspergualin (2, 5, or 10 mg/kg daily), all given from the day of transplantation until day 9, protected the grafts during the treatment period. The addition of LS-2616 (160 mg/kg, day -1 until stop) resulted in a total abrogation of the immunosuppressive effect of CyA and prednisolone. However, LS-2616 could only partially or not at all reverse the effect of 15-deoxyspergualine. These results show a certain drug selectivity of LS-2616 in promoting rejection of immunosuppressed allografts. Further studies with LS-2616 may be of benefit in evaluating the mode of action of different immunosuppressive compounds and, thus, contribute to finding more effective antirejection therapies.
