获得性免疫缺陷综合征(AIDS)的演变涉及淋巴细胞亚群的改变,这可能是潜在疾病过程的重要组成部分。淋巴细胞亚群的这些变化包括T4:T8比值的倒置,这是由于T4阳性细胞的绝对数量减少以及T8阳性细胞的数量正常或略微升高[1]。随着疾病的进展,淋巴细胞减少导致T4'和T8'细胞的绝对数量降低,并且T4:T8比率变得甚至更低。在巨细胞病毒(CMV)、疱疹病毒或EB病毒(EBV)等病毒感染中,也会发生T4'与T8'细胞比例的逆转,这种影响可能在恢复后持续数月[2]。这些病毒感染的逆转主要是由于T8+细胞群的急剧扩增,尽管T4'细胞的数量确实减少。因此,在AIDS中,T4:T8比率的逆转反映了这些T细胞亚群的绝对代表性与在其他病毒感染中观察到的略有不同,尽管对T4'和T8'细胞的相对比例的影响可能是相似的。
The evolution of acquired immunodeficiency syndrome (AIDS) involves alterations in lymphocyte subpopulations that may be a significant part of the underlying disease process. These alterations in lymphocyte subsets include an inversion of the T4: T8 ratio that is due to a reduction in the absolute numbers of T4 positive cells and either normal numbers or slightly elevated numbers of T8 posi-tive cells [1]. As the disease progresses, lymphopenia results in lower absolute numbers of both T4'and T8'cells and the T4: T8 ratio becomes even more reduced. In viral infections with such viruses as cytomegalovirus (CMV), herpesvirus, or Epstein-Barr virus (EBV) a reversal in the ratio of T4'to T8'cells also occurs, and the ef-fect may persist for months after recovery [2]. The rever-sal in these viral infections is primarily due to a dramatic expansion of the T8+ population, although a reduction in the numbers of T4'cells does occur. Thus, in AIDS the reversal of the T4: T8 ratio reflects a somewhat different absolute representation of these T cell subpopulations than is observed in other viral infections, although the effect on the relative proportion of T4'and T8'cells may be similar.
