| Title | Safe Administration of Immunosuppression in Japanese Monkeys: Relevance to Preclinical Xenotransplantation Studies. |
| Journal | Cell Transplant |
| Abstract |
The Japanese monkey has been used in several animal studies; however, its potential as a recipient model for xenotransplantation is unclear. The potential of the Japanese monkey as a recipient for xenotransplantation was assessed using two experimental models. The first model evaluated the optimal dose of tacrolimus without severe adverse events. The plasma tacrolimus levels, blood counts, and hepatic and renal function tests were evaluated. The second model assessed the immunosuppressive effects of thymoglobulin and tacrolimus. Immunosuppression was evaluated using blood counts and flow cytometry to measure lymphocytes in peripheral blood mononuclear cells (PBMCs). In the first model, the target trough level (10-15 ng/ml) was achieved and maintained with tacrolimus administration at 1.6 mg/kg/day in all monkeys. There were no adverse events related to the blood count or to liver, kidney, or nutrient parameters at this dose, except for hemoglobin. In the second model, a decrease in white blood cells was observed. Flow cytometry revealed a temporary decrease in T- and B-cell numbers among PBMCs on day 4. We consider that the Japanese monkey is acceptable to be used as a recipient model for preclinical xenotransplantation. The safe administration of tacrolimus and thymoglobulin is clarified for this model. |
