From Focus: Immune-suppressant therapies may prevent rejection of transplanted tissues, but they also raise the risk of deadly infection. Xin Xiao Zheng (left) and Terry Strom report an alternative method for achieving immune tolerance: allow the immune response to proceed, but then skew it so tissue-protecting T cells vastly outnumber tissue-killing T cells. Mice receiving the treatment before and after a transplant did not reject the tissue and reacted normally to later immune challenges.
