【摘要】:濾泡輔助性T細(xì)胞(Tfh)是最近發(fā)現(xiàn)的一群具有B細(xì)胞輔助功能的細(xì)胞群,在機(jī)體體液免疫中發(fā)揮重要作用。Tfh是艾滋病病毒(HIV)感染和復(fù)制的重要位點(diǎn),是HIV的重要病毒庫。研究發(fā)現(xiàn),Tfh在HIV感染中發(fā)生了數(shù)量、功能、表型等一系列變化,這些變化可能與HIV感染中體液免疫缺陷的發(fā)生有關(guān)。HIV感染中,調(diào)節(jié)性T細(xì)胞(Treg)以及新近發(fā)現(xiàn)的濾泡調(diào)節(jié)T細(xì)胞(Tfr)與Tfh在數(shù)量及功能方面的失衡,可能造成了HIV免疫異常激活及免疫缺陷,這兩者在HIV感染中相對(duì)數(shù)量及功能的變化及其與HIV感染疾病進(jìn)展的關(guān)系,值得進(jìn)一步深入的研究。
[Abstract]:Follicular helper T cell (TfH) is a recently discovered group of B cell-assisted cells. Tfh plays an important role in humoral immunity. Tfh is an important site for HIV infection and replication and an important viral library for HIV. Tfh has a series of changes in HIV infection, such as number, function, phenotype and so on. These changes may be related to the occurrence of humoral immune deficiency in HIV infection. The imbalance between regulatory T cell tregand and newly discovered follicle-regulated T cell tfrand and Tfh may lead to abnormal activation and immune deficiency of HIV. The changes of relative quantity and function in HIV infection and their relationship with the progression of HIV infection are worthy of further study.
