目的:间质干细胞能够逃避免疫识别,抑制免疫反应特征。文章就近年来间质干细胞及其免疫调节作用进行综述。资料来源:应用计算机检索PUBMED 1976-01/2006-01期间的相关文章,检索词为"mesenchymal st.m cells,immune modulat.on",并限定文章语言种类为English。资料选择:对资料进行初审,并查看每篇文献后的引文。纳入标准:文章所述内容应与间质干细胞及其免疫调节作用相关。排除标准:重复研究或Met.分析类文章。资料提炼:共收集到263篇相关文献,68篇文献符合纳入标准,排除的195篇文献为内容陈旧或重复。符合纳入标准的68篇文献中,分别涉及间质干细胞的免疫原性、免疫抑制作用及机制、应用等内容。资料综合:间质干细胞广泛存在于各种组织中,本身具有免疫原性低的特点,可以逃避同种异基因免疫识别。间质干细胞在体外、体内均有明确的免疫抑制作用,与间质干细胞对树突状细胞、t.胞、自然杀伤细胞等的调控作用有关。间质干细胞尚可对转化生长因子、白细胞介素、基质细胞来源因子、NF-κB配体、前列腺素、吲哚胺2,3-二氧酶等可溶性因子产生影响。由于间质干细胞多方面的免疫调节活性,使其拥有良好的应用前景,目前已在移植物抗宿主病及自身免疫疾病的治疗中发挥了作用。结论:间质干细胞无论在体内或体外均对t.胞的活化有抑制作用,可调节在同种异体抗原的识别和清除过程中主要细胞群的免疫功能,包括抗原递呈细胞、t.胞和自然杀伤细胞,但其调节免疫抑制作用的分子机制尚未被完全阐明。
