  • Beschreibung: <jats:sec> <jats:title>Objectives:</jats:title> <jats:p>Few single latency-reversing agents (LRAs) have been tested in vivo, and only some of them have demonstrated an effect, albeit weak, on the decrease of latent reservoir. Therefore, other LRAs and combinations of LRAs need to be assessed. Here, we evaluated the potential of combined treatments of therapeutically promising LRAs, disulfiram and romidepsin.</jats:p> </jats:sec> <jats:sec> <jats:title>Setting and Methods:</jats:title> <jats:p>We assessed the reactivation potential of individual disulfiram or simultaneous or sequential combined treatments with romidepsin in vitro in latently infected cell lines of T-lymphoid and myeloid origins and in ex vivo cultures of CD8<jats:sup>+</jats:sup>-depleted peripheral blood mononuclear cells isolated from 18 HIV-1<jats:sup>+</jats:sup> combination antiretroviral therapy–treated individuals.</jats:p> </jats:sec> <jats:sec> <jats:title>Results:</jats:title> <jats:p>We demonstrated heterogeneous reactivation effects of disulfiram in vitro in various cell lines of myeloid origin and no latency reversal neither in vitro in T-lymphoid cells nor ex vivo, even if doses corresponding to maximal plasmatic concentration or higher were tested. Disulfiram+romidepsin combined treatments produced distinct reactivation patterns in vitro. Ex vivo, the combined treatments showed a modest reactivation effect when used simultaneously as opposed to no viral reactivation for the corresponding sequential treatment.</jats:p> </jats:sec> <jats:sec> <jats:title>Conclusions:</jats:title> <jats:p>Exclusive reactivation effects of disulfiram in myeloid latency cell lines suggest that disulfiram could be a potential LRA for this neglected reservoir. Moreover, distinct reactivation profiles pinpoint heterogeneity of the latent reservoir and confirm that the mechanisms that contribute to HIV latency are diverse. Importantly, disulfiram+romidepsin treatments are not potent ex vivo and most likely do not represent an effective drug combination to achieve high levels of latency reversal in vivo.</jats:p> </jats:sec>
