【摘要】 背景:间充质干细胞拥有强大的免疫调节能力,主要表现在调控免疫细胞的增殖、分化和功能状态,调节炎症因子的分泌等。间充质干细胞的免疫调节能力受炎症因子调控,依据微环境中炎症因子的种类、水平,间充质干细胞的免疫调节功能也会发生变化。目的:综述炎症因子影响间充质干细胞免疫调控特性的研究进展。方法:应用计算机检索PubMed数据库、Elsevier数据库、CNKI数据库,中文检索关键词或主题词为"间充质干细胞,免疫调节,可塑性,干扰素γ,转化生长因子β,白细胞介素17,白细胞介素35,前列腺素E2",英文检索关键词为"mesenchymal stem cells,immune regulation,plasticity,interferon gamma,transforming growth factor beta,interleukin17,interleukin 35,prostaglandin E2"。纳入炎症因子干预影响间充质干细胞免疫调控特性的相关文献。结果与结论:采用干扰素γ、转化生长因子β、白细胞介素17、白细胞介素35和前列腺素E2干预或预处理后,间充质干细胞的生物学特性随之改变,不但可重塑组织微环境、影响炎症反应,而且可重建免疫平衡,进而治疗疾病或缓解疾病进展。针对炎症、免疫反应的不同,在疾病的不同阶段进行合理的个体化、差异化治疗,都有望进一步提高间充质干细胞对免疫炎症性疾病的治疗效果。更多还原

【Abstract】 BACKGROUND: Mesenchymal stem cells possess strong immunomodulatory capacity, mainly involved in the proliferation, differentiation and functional status of immune cells, and the secretion of inflammatory factors. The immunomodulatory capacity of mesenchymal stem cells is regulated by inflammatory factors. As the type and level of inflammatory factors in the microenvironment change, the immune regulation function of mesenchymal stem cells also changes. OBJECTIVE: To review the research progress of inflammatory factor intervention in the immune regulation of mesenchymal stem cells. METHODS: A computer-based retrieval of PubMed, Elsevier and CNKI databases was performed. The keywords were "mesenchymal stem cells, immune regulation, plasticity, interferon gamma, transforming growth factor beta, interleukin-17, interleukin-35, prostaglandins E2" in Chinese and English, respectively. The articles concerning the effects of inflammatory factor intervention on the immune regulation of mesenchymal stem cells were included. RESULTS AND CONCLUSION: After intervention and pre-treatment of interferon-γ, transforming growth factor-β, interleukin-17, interleukin-35 and prostaglandin E2, the biological characteristics of mesenchymal stem cells have also changed. The interventions cannot only reshape the tissue microenvironment and affect the inflammatory response, but also reconstruct the immune balance, which further treats or alleviates the disease progression. Reasonable individualized and differentiated treatments will be performed at different disease stages according to inflammatory and immunological reaction of the disease. All of them are expected to further improve the therapeutic effect of mesenchymal stem cells on immuno-inflammatory diseases.更多还原
