HIV migration between blood plasma and cellular subsets before and after HIV therapy.

ABSTRACT: The cellular source of HIV RNA circulating in blood plasma remains unclear. Here, we investigated whether sequence analysis of HIV RNA populations circulating before combination antiretroviral therapy (cART) and HIV DNA populations in cellular subsets (CS) after cART could identify the cellular sources of circulating HIV RNA. Blood was collected from five subjects at cART initiation and again 6 months later. Naïve CD4+ T cells, resting central memory and effector memory CD4+ T cells, activated CD4+ T cells, monocytes, and natural killer cells were sorted using a fluorescence-activated cell sorter. HIV-1 env C2V3 sequences from HIV RNA in blood plasma and HIV DNA in CSs were generated using single genome sequencing. Sequences were evaluated for viral compartmentalization (Fst test) and migr
