In this study, we investigated whether pomalidomide, an immunomodulatory agent that induces degradation of Ikaros and Aiolos, could increase the death of HIV-infected cells and\/or reverse HIV latency. Using an\n              <jats:italic>in vitro<\/jats:italic>\n              model of CD4+ T cells infected with a green fluorescent protein (GFP) reporter virus, pomalidomide increased the expression of the pro-survival protein B cell lymphoma (Bcl)-2 and did not increase apoptosis of GFP+ HIV productively infected CD4+ T cells. Pomalidomide also increased the expression of CD155 and UL16-binding protein (ULBP) stress proteins on GFP+ HIV productively infected CD4+ T cells, but this did not translate to enhanced clearance following co-culture with a natural killer (NK) cell line. Using CD4+ T cells from PLHIV on ART, pomalidomide\n              <jats:italic>ex vivo<\/jats:italic>\n              activated memory CD4+ T cells resulting in elevated HLA-DR expression and induced CD4+ T cell proliferation but only in the presence of T cell receptor stimulation with anti-CD3 and anti-CD28. There was no effect on cell-associated HIV RNA or the frequency of intact HIV DNA. In conclusion, despite an increase in stress protein expression, promoting Ikaros and Aiolos degradation in CD4+ T cells using pomalidomide did not directly induce apoptosis of HIV-infected cells or induce HIV latency reversal.\n            <\/jats:p>\n            <jats:sec>\n              <jats:title>\n                <jats:bold>IMPORTANCE<\/jats:bold>\n              <\/jats:title>\n              <jats:p>\n                People living with HIV (PLHIV) require lifelong antiretroviral therapy (ART) due to the persistence of latently infected cells. The zinc finger proteins, Ikaros and Aiolos, have recently been implicated in promoting the persistence of latently infected cells. In this study, we investigated the effects of pomalidomide, an immunomodulatory imide drug that induces the degradation of Ikaros and Aiolos, on HIV latency reversal and death of infected cells.
