Critical issues emerging from current attempts at inducing transplantation tolerance in the clinic include the need for biomarkers that predict and diagnose tolerance as well as for the identification of barriers to tolerance induction and maintenance. Our preliminary observations have led us to the realization that the durability of the tolerant state is variable and can be unpredictably breached by Listeria infections. The overall goal of the proposed studies Is to determine a mechanistic basis for how Infections can either erode or transiently abrogate robust tolerance after It has been stably established.

从目前临床上诱导移植耐受的尝试中出现的关键问题包括 需要生物标志物来预测和诊断耐受性以及识别耐受性障碍 诱导和维护。我们的初步观察使我们认识到， 耐受状态是可变的，可能会被李斯特菌感染意外地打破。该计划的总体目标 建议的研究是确定感染如何侵蚀或短暂的机制基础。 在它稳定地建立之后，废除健壮的容忍度。
