Abstract

Chronic lung allograft dysfunction (CLAD) remains one of the major limitations to long-term survival after lung transplantation. We modified a murine model of CLAD and transplanted left lungs from BALB/c donors into B6 recipients that were treated with intermittent cyclosporine and methylprednisolone postoperatively. In this model, the lung allograft developed acute cellular rejection on day 15 which, by day 30 after transplantation, progressed to severe pleural and peribronchovascular fibrosis, reminiscent of changes observed in restrictive allograft syndrome. Lung transplantation into splenectomized B6 alymphoplastic (aly/aly) or splenectomized B6 lymphotoxin-β receptor-deficient mice demonstrated that recipient secondary lymphoid organs, such as spleen and lymph nodes, are necessary for progression from acute cellular rejection to allograft fibrosis in this model. Our work uncovered a critical role for recipient secondary lymphoid organs in the development of CLAD after pulmonary transplantation and may provide mechanistic insights into the pathogenesis of this complication.

摘要

慢性肺移植功能障碍(CLAD)仍然是肺移植后长期生存的主要限制因素之一。我们修改了 CLAD 的小鼠模型,并将 BALB/c 供体的左肺移植到术后接受间歇性环孢素和甲基强的松龙治疗的 B6 受体中。在该模型中,肺移植物在第 15 天发生急性细胞排斥反应,在移植后第 30 天进展为严重的胸膜和支气管血管周围纤维化,类似于在限制型移植物综合征中观察到的变化。将肺移植到脾切除的 B6 无淋巴形成(aly/aly)或脾切除的 B6 淋巴毒素-β 受体缺陷型小鼠中表明,受体二级淋巴器官,如脾和淋巴结,对于该模型中从急性细胞排斥反应进展为移植物纤维化是必需的。我们的工作揭示了受体二级淋巴器官在肺移植后 CLAD 发展中的关键作用,并可能为该并发症的发病机制提供机制见解。
