霉酚酸酯(MMF)是一种免疫抑制剂,用于治疗自身免疫性和炎症性疾病,以及器官移植后。MMF治疗通过DNA合成所需的嘌呤耗竭导致淋巴细胞减少症。虽然认为MMF治疗的主要作用是通过淋巴细胞耗竭,但MMF也与先天性免疫缺陷相关,包括中性粒细胞减少症和中性粒细胞发育不良。在这里,我们解决的问题,霉酚酸酯对中性粒细胞在斑马鱼中性粒细胞炎症的动物模型的具体影响。我们发现,组织损伤后,霉酚酸酯通过增加中性粒细胞凋亡来增加嗜中性粒细胞炎症的消退。关键的是,我们通过使用嘌呤核苷酸掺入的竞争性抑制剂硫唑嘌呤,确定了MMF的作用不同于DNA合成抑制。因此,我们认为炎症过程中中性粒细胞死亡增加可能在与MMF治疗相关的中性粒细胞缺陷中发挥作用。
Mycophenolate mofetil (MMF) is an immunosuppressive agent used in the treatment of autoimmune and inflammatory conditions, and following organ transplant. MMF treatment results in lymphopenia via the depletion of purines required for DNA synthesis. While the primary effect of MMF treatment is thought to be via the depletion of lymphocytes, MMF has also been associated with innate immune defects, including neutropenia and neutrophil dysplasia. Here, we address the question of MMF specific effects on neutrophils in anin vivomodel of neutrophil inflammation in zebrafish. We find that, following tissue injury, MMF increases resolution of neutrophilic inflammation via increased neutrophil apoptosis. Critically, we identify that the effect of MMF is distinct from DNA synthesis inhibition by using the competitive inhibitor of purine nucleotide incorporation, azathioprine. Therefore, we propose that increased neutrophil cell death during inflammatory insult may play a role in neutrophil defects associated with MMF treatment.
