Table 1 Evaluation of viral recovery in ex vivo cultures of CD8+ depleted PBMCs from six ART-treated HIV+ aviremic PLWH. Ex vivo cultures of CD8+-depleted PBMCs from six ART-treated HIV+ PLWH were mock treated, treated with ALKi-3 [100µM], Romidepsin [17.5nM], combined ALKi-3 + Romidepsin or with a with PMA/I cocktail as a positive control (C+) in the presence of ARV [280 nM Ritonavir, 180 nM Azidothymidine, 200 nM Raltegravir, 100 nM efavirenz]. Three days post-treatment, concentrations of genomic viral RNA in culture supernatants were determined and the values were expressed as HIV-1 RNA copies/ml. Total HIV-1 DNA was expressed as HIV-1 DNA copies/106 CD8+-depleted PBMCs. Values representing higher viral production after the combined treatment than after the single drug treatments are shown in grey. ‘/’ indicates below the 75 HIV-1 RNA copies/ml limit of detection
