ABSTRACT

Objective:

To investigate the impact of the CD4+CD25nt/hiCD127lo regulatory T cell subset frequency on the immune status and disease progression of Chinese HIV-1 infected individuals.

Methods:

83 untreated HIV-infected individuals and 312 healthy control individuals of four distinct age groups were enrolled in the research. The CD4+ T cell absolute counts, phenotypes and frequency determination of CD4+CD25nt/hiCD127lo Regulatory T cell subsets was performed on freshly obtained whole blood samples by 3-color immune staining flow cytometry. The HIV-1 specific cellular immune function was test at single cell level by ELISpot. The corresponding plasma viral load was determined by NASBA.

Results:

The frequency of peripheral CD4+CD25nt/hiCD127lo regulatory T cells of HIV infected individuals in distinct disease progression status was dissimilar in China , and significantly increased in contrast to the healthy controls(P
