After more than a decade of preclinical and clinical development, therapeutic infusion of mesenchymal stromal cells is now a leading investigational strategy for the treatment of acute graft-versus-host disease (GVHD). While their clinical use continues to expand, it is still unknown which of their immunomodulatory properties contributes most to their therapeutic activity. Herein we describe the proposed mechanisms, focusing on the inhibitory activity of mesenchymal stromal cells (MSCs) at immunologic checkpoints. A deeper understanding of the mechanism of action will allow us to design more effective treatment strategies.
经过十多年的临床前和临床开发,间充质基质细胞的治疗性输注现已成为治疗急性移植物抗宿主病(GVHD)的主要研究策略。尽管它们的临床应用在不断扩大,但仍不清楚它们的哪种免疫调节特性对其治疗活性贡献最大。在此,我们描述了所提出的机制,重点是间充质基质细胞(MSCs)在免疫检查点的抑制活性。对作用机制的更深入理解将使我们能够设计出更有效的治疗策略。
