人类免疫缺陷病毒(HIV)感染中CD 8 + T细胞保护性免疫的关键属性仍不清楚。我们报告说,CD 8 + T细胞反应特异性Gag,特别是免疫显性p24表位KK 10与人类组织相容性白细胞抗原(HLA)-B27患者的HIV-1复制的控制。为了进一步了解CD 8 + T细胞介导的抗病毒功效的性质,我们基于使用多参数流式细胞术以及分子克隆型分析和病毒测序,对慢性HIV-1感染中HLA-B27限制性表位KK 10特异性的CD 8 + T细胞进行了全面研究。我们发现,B27-KK 10特异性CD 8 + T细胞的特点是多功能的能力,增加克隆周转,和上级功能的亲和力。这些属性是相互关联的,构成了有效控制HIV-1复制的基础。这些关于HIV感染中有效CD 8 + T细胞特征的数据可能有助于开发成功的T细胞疫苗。
The key attributes of CD8+ T cell protective immunity in human immunodeficiency virus (HIV) infection remain unclear. We report that CD8+ T cell responses specific for Gag and, in particular, the immunodominant p24 epitope KK10 correlate with control of HIV-1 replication in human histocompatibility leukocyte antigen (HLA)–B27 patients. To understand further the nature of CD8+ T cell–mediated antiviral efficacy, we performed a comprehensive study of CD8+ T cells specific for the HLA-B27–restricted epitope KK10 in chronic HIV-1 infection based on the use of multiparametric flow cytometry together with molecular clonotypic analysis and viral sequencing. We show that B27-KK10–specific CD8+ T cells are characterized by polyfunctional capabilities, increased clonal turnover, and superior functional avidity. Such attributes are interlinked and constitute the basis for effective control of HIV-1 replication. These data on the features of effective CD8+ T cells in HIV infection may aid in the development of successful T cell vaccines.
