中文摘要: |
CD4+CD25+FOXP3+ 的调节T 细胞(regulatory T cells,Treg)在维持机体免疫平衡方面起着重要的作用。体外扩增Treg 细
胞用于治疗自身免疫病、哮喘及诱导器官移植免疫耐受引起人们极大的兴趣。Treg 细胞可分为2 个亚群,分别为nTreg 和iTreg,
两者有不同的生物学特性。nTreg 在特定条件下,可以分泌具有促进炎症的IL-17;iTreg 在体内可丢失FOXP3,失去其免疫抑制功
能。Treg 细胞用于临床治疗,还有许多问题需要研究解决。 |
英文摘要: |
CD4+CD25+FOXP3+ regulatory T cells is more important for keeping the immune system in homeostatic balance.
There is more increasing attention in large-scale expansion of regulatory T cells for therapeutic autoimmune disease, asthma and inducing
immune tolerance for organ transplant. There are two subgroup in regulatory T cells, named naturally occurring Tregs (nTreg) and inducible
Tregs(iTreg), respectively. There are some differences between nTreg and iTreg cells in biology characteristics. The nTreg is able
to produce IL-17 cytokine which can promote proinflammatory under specific environment. The iTreg may lose FOXP3 expression and
miss its immune suppression. Many questions must be solved before Tregs as cellular therapeutics. |
