Cell-associated HIV-1 RNA was quantified in peripheral CD4+ T cells by ddPCR (One-Step RT-ddPCR Advanced Kit for Probes, BioRad) from samples taken before (0 h) and at the end of each RMD infusion (4 h), at 8 and 24 h (+1 day) after RMD1, and 72 h (+3 days) and 7 days after RMD1−2−3. CA HIV-1 RNA was quantified using two different primers/probe sets annealing to the 5′LTR and GAG conserved regions of HIV-1, to circumvent potential primer mismatch in individuals' viral sequence as previously described (37 (link)). HIV-1 transcription levels were normalized to the housekeeping gene TATA-binding protein (TBP) and shown as relative to levels before RMD1.
