概括
在干细胞移植后,Withhania somnifera提取物 (WSE) 有效地预防和治疗急性移植与宿主疾病 (aGvHD). 在不影响移植与白血病效应的情况下,WSE可降低死亡率和器官损伤.
科学领域:
- 免疫学 免疫学 免疫学
- 药理学 药理学 是一个学科.
- 移植医学 移植医学
背景情况:
- 急性移植与宿主疾病 (aGvHD) 是异性造血干细胞移植 (alloHSCT) 后的主要死亡原因.
- aGvHD涉及有害的炎症性免疫反应,其特征是细胞因子风暴和肝脏,肠道和皮肤等重要器官的损伤.
- 平衡aGvHD预防与关键的移植与白血病 (GvL) 效应是一个重要的临床挑战.
研究的目的:
- 调查Withania somnifera提取物 (WSE) 在缓解aGvHD.的疗效.
- 在实验性alloHSCT模型中评估WSE在预防和治疗环境中的保护作用.
- 评估WSE对GvL活动的影响及其直接的抗白血病潜力.
主要方法:
- 使用alloHSCT的实验模型来测试WSE.
- 评估了以不同剂量 (75 mg/kg和 250 mg/kg) 给予 WSE 的预防和治疗作用.
- 组织病理学分析和细胞因子水平被评估以确定器官保护和免疫调节.
主要成果:
- 75 mg/kg的预防性WSE显著降低了与GvHD相关的死亡率 (HR=0.15,P≤0.01).
- 250 mg/kg的治疗性WSE也显著降低了死亡率 (HR=0.16,P≤0.01).
- 通过抑制细胞因子风暴和淋巴细胞透,WSE治疗保护了肝脏,肠道和皮肤,而不会损害GvL效应.
结论:
- 维他尼亚·索姆尼费拉提取物显示出预防和治疗急性移植与宿主疾病的巨大潜力.
- 通过调节炎症反应和保护位器官,WSE减轻aGvHD病理.
- 白血病疹是alloHSCT的一种有前途的治疗剂,在不影响抗白血病疗效的情况下提供对aGvHD的保护,目前正在临床研究中.

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.

Tissue Transplantation
372
Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
