HIV-1 Elite Controllers are Characterised by Elevated Levels of CD69-Expressing Natural Killer Cells.

ABSTRACT:

Background

Human immunodeficiency virus type 1 (HIV-1) elite controllers (ECs) are a rare subset of people living with HIV-1 (PLWH) who control viral replication in the absence of antiretroviral therapy (ART) and may provide a model for a functional cure. We investigated the role of natural killer (NK) cells in HIV-1 ECs from South Africa.

Methods

Phenotypic (CD69, CD38, CD57, PD-1), functional (CD107a, IFN-γ), and nutrient transporter profiles (glucose transporter 1, CD98) of NK cells from ECs (n=20), viraemic progressors (VPs; n=19), people living with HIV-1 (PLWH) on ART (n=20), and people without HIV-1 (PWOH; n=21) were analysed using flow cytometry. The Kruskal-Wallis test followed by the Mann-Whitney U test were used to determine differences among the study groups. The
