Deskripsi
The immune checkpoint molecule PD-1 is expressed on a fraction of CD4+ T cells latently infected with HIV, but whether PD-1 plays a functional role in reservoir persistence remains unknown. Here, Fromentin et al. show that PD-1 blockade potentiates latency reversal ex vivo in CD4+ T cells from ART suppressed individuals.
