Dendritic cell therapy improves kidney transplant survival, Pitt team says
Date:6/28/2013

roup of monkeys was transplanted without receiving the cells, but both groups were given the same regimen of immunosuppression drugs, a modified protocol for experimental purposes that eventually results in donor organ rejection. The researchers found that the donor kidney was rejected in about 40 days among animals that got only the drugs, but survived for about 113 days in the group that had a prior infusion of treated DCs.

The modified donor DCs sent signals to the recipient immune system to stay quiet and not launch an attack against the donor organ, explained lead author Mohamed Ezzelerab, M.D., research assistant professor, Department of Surgery, Pitt School of Medicine.

"The results indicate that we achieved immune system regulation without side effects of the DCs, but better yet, the monkeys were healthier from a clinical perspective," he said. "They maintained a better weight, had less protein in the urine and fewer signs of kidney damage than the other group. Ultimately, all these factors played a role in prolonging organ survival in the group that received DC therapy."
