Title HIV-1 infection of human monocyte-derived dendritic cells with and without the integrase inhibitor, Raltegravir (gene expression).
Organism Homo sapiens
Experiment type Expression profiling by array
Summary Myeloid dendritic cells (DCs) have the innate capacity to sense pathogens and orchestrate immune responses. However, DCs do not mount efficient immune responses to HIV-1, due to potent restriction at the level of reverse transcription. Here, we uncover that when reverse transcription is allowed to proceed, DCs detect HIV-1 in distinct phases, before and after integration. Blocking integration suppressed, but did not abolish, activation of the transcription factor, IRF3, interferon responses, and DC maturation. The cytoplasmic DNA sensor, cGAS, and the E3 ligase, TRIM5, were both required for these responses. Consistent with two stages of innate activation, HIV-1 altered host chromatin accessibility before and after integration. Our studies support the hypothesis that HIV-1 replication increases the amount of material available for sensing and that cGAS signaling can be tuned by discrete inflammatory inputs to drive DC maturation.
 
Overall design DCs were derived from the peripheral blood from two deidentified human donors and infected with a single-cycle HIV-1 reporter virus (HIV-GFP) in the presence of Vpx, with and without Raltegravir. RNA expression was measured at 0, 8, 16, 20, 24, 28, 32, and 40 hours after infection.
