A major goal for the field of regenerative medicine is to enable the safe and durable engraftment of allogeneic tissues and organs. In contrast to autologous therapies, allogeneic therapies can be produced for many patients, thus reducing costs and increasing availability. However, the need to overcome strong immune system barriers to engraftment poses a significant biological challenge to widespread adoption of allogeneic therapies. While the use of powerful immunosuppressant drugs has enabled the engraftment of lifesaving organ transplants, these drugs have serious side effects and often the organ is eventually rejected by the recipient immune system. Two conceptually different strategies have emerged to enable durable engraftment of allogeneic therapies in the absence of immune suppression. One strategy is to induce immune tolerance of the transplant, either by creating “mixed chimerism” in the hematopoietic system, or by retraining the immune system using modified thymic epithelial cells. The second strategy is to evade the immune system altogether, either by engineering the donor tissue to be “invisible” to the immune system, or by sequestering the donor tissue in an immune impermeable barrier. We give examples of research funded by the California Institute for Regenerative Medicine (CIRM) in each of these areas, ranging from early discovery‐stage work through clinical trials. The advancements that are being made in this area hold promise that many more patients will be able to benefit from regenerative medicine therapies in the future.

启用同种异体疗法:CIRM资助的免疫耐受和免疫逃避策略。

再生医学领域的主要目标是使同种异体组织和器官安全,持久地植入。与自体疗法相反,可以为许多患者提供同种异体疗法,从而降低了成本并提高了可用性。然而,需要克服强大的免疫系统植入障碍,这对同种异体疗法的广泛采用提出了重大的生物学挑战。尽管使用强大的免疫抑制剂药物可以植入救生器官移植物,但这些药物具有严重的副作用,通常器官最终会被受体免疫系统排斥。已经出现了两种概念上不同的策略,可以在没有免疫抑制的情况下持久移植同种异体疗法。一种策略是通过在造血系统中产生“混合嵌合体”或通过使用修饰的胸腺上皮细胞重新训练免疫系统来诱导移植物的免疫耐受。第二种策略是通过使供体组织对免疫系统“不可见”或通过将供体组织隔离在免疫不可渗透的屏障中来完全逃避免疫系统。我们列举了由加利福尼亚再生医学研究所(CIRM)资助的每个领域的研究实例,涉及从早期发现阶段的工作到临床试验。该领域的进步有望使更多的患者将来能够从再生医学治疗中受益。或者使用修饰的胸腺上皮细胞训练免疫系统。第二种策略是通过使供体组织对免疫系统“不可见”或通过将供体组织隔离在免疫不可渗透的屏障中来完全逃避免疫系统。我们列举了由加利福尼亚再生医学研究所(CIRM)资助的每个领域的研究实例,涉及从早期发现阶段的工作到临床试验。该领域的进步有望使更多的患者将来能够从再生医学治疗中受益。或者使用修饰的胸腺上皮细胞训练免疫系统。第二种策略是通过使供体组织对免疫系统“不可见”或通过将供体组织隔离在免疫不可渗透的屏障中来完全逃避免疫系统。我们列举了由加利福尼亚再生医学研究所(CIRM)资助的每个领域的研究实例,涉及从早期发现阶段的工作到临床试验。该领域的进步有望使更多的患者将来能够从再生医学治疗中受益。或通过隔离免疫屏障来隔离供体组织。我们列举了由加利福尼亚再生医学研究所(CIRM)资助的每个领域的研究实例,涉及从早期发现阶段的工作到临床试验。该领域的进步有望使更多的患者将来能够从再生医学治疗中受益。或通过隔离免疫渗透屏障隔离供体组织。我们列举了由加利福尼亚再生医学研究所(CIRM)资助的每个领域的研究实例,涉及从早期发现阶段的工作到临床试验。该领域的进步有望使更多的患者将来能够从再生医学治疗中受益。
