摘要
树突状细胞(DC)是功能最强的抗原递呈细胞(APC),在移植免疫中,DC启动免疫排斥还是维持免疫耐受取决它们的起源以及成熟状态,成熟DC启动免疫排斥及移植物抗宿主病(GVHD)反应,未成熟(iDC)及淋巴样DC诱导免疫耐受。造血干细胞移植(HSCT)中,可以通过调控不同来源、不同分化状态的DC来预防和治疗移植物抗宿主病(GVHD),促进造血干细胞的植入。
Dendritic cells (DCs) are the most potent antigen presenting cells. In transplantation immunity , whether DCs induce rejection or tolerance depends on the source and maturation of DCs. Mature DCs are able to initiate rejection response and graft versus host disease ( GVHD), while immature DCs or plasmacytoid DCs induce immunity tolerance. In hematopoietic stem cell transplantation( HSCT), different originated and differentiated DCs can be modulated to prevent and cure GVHD, and to promote engraftment of hematopoietic stem cells.
