N2 - The relative contribution of regulatory T cells (Treg) as reservoir of HIV-1 in patients on chronic antiretroviral therapy is unclear to date. The aim of the current study was to assess the total HIV DNA burden and replication competent viral reservoir in Treg in comparison to central and effector memory cells (Tcm and Tem). Peripheral blood mononuclear cells were obtained from 10 HIV patients treated with antiretroviral therapy and one HIV elite controller. Droplet Digital PCR (ddPCR) was used to quantify total HIV DNA loads in FACS sorted CD4+ Treg (CD25+CD127lo) as compared with Tcm (CD45RO+CCR7+) and Tem (CD45RO+CCR7-). In contrast to earlier reports, no significant difference was found in total HIV DNA burden associated with Treg when compared to Tem and Tcm cells. In a subset of patients, quantitative viral outgrowth assays were also performed, using novel ddPCR based readout to quantify frequencies of Treg harboring replication competent virus.
