HIV-1 indcued genes in human monocyte-derived macrophages

Project description:HIV-1 infection of monocyte-derived macrophages does not elicit a detectable type I IFN response in vitro, however, previously published data has shown that blocking STAT1 and STAT3 inhibits HIV-1 replication. Here we test to see if low levels of IFN inducible genes are detectable in human monocyte-derived macrophages that have been infected with HIV-1 in vitro.

HIV Induces RSAD2/Viperin To Promote Sustained Infection of Monocyte-Derived Macrophages

Project description:HIV establishes long-term latent infection in memory CD4+ T cells, but also establishes sustained long-term productive infection in macrophages, especially in the CNS. To better understand how HIV sustains infection in macrophages, we performed RNAseq analysis after infection of human-monocyte derived macrophages (MDMs) with the brain-derived HIV-1 strain YU2 and compared this with acute infection of CD4+ T cells. HIV infection in MDM and CD4+ T-cells altered many gene transcripts, but with few overlaps between these different cell types. We found interferon pathways upregulated in both MDM and CD4+ T-cells, but with different gene signatures. The interferon-stimulated gene RSAD2/Viperin was among the most upregulated genes following HIV infection in MDMs, but not in CD4+ T-cells. RSAD2/Viperin was induced early after infection with various HIV strains, was sustained over time, and remained elevated in established MDM infection even if new rounds of infection were blocked by antiretroviral treatment. Immunofluorescence microscopy revealed that RSAD2/Viperin was induced strongly in HIV infected cells, as well as in some uninfected neighboring cells, and was frequently localized at junctions between cells. Knockdown of RSAD2/Viperin following establishment of infection in MDMs reduced production of HIV transcripts and viral p24 antigen. This correlated with reduction in the number of multinucleated giant cells, and changes in the histone modifications at the HIV LTR, including loss of histone H3K7ac and H3K9me3, epigenetic marks that we have found associated with HIV in MDMs. RNA-seq transcriptomic analysis of RSAD2/Viperin knockdown during HIV infection of MDMs revealed activation of interferon alpha and gamma pathways and inactivation of Rho GTPase pathways. Taken together, these results suggest that RSAD2/Viperin supports HIV infection in macrophages through multiple mechanisms, potentially including the attenuation of the interferon response.

Expression data from human monocyte derived macrophages infected with adenovirus expressing HIV-1 Vpr

Project description:HIV-1 Vpr protein is a multifunctional protein which perturbs human transcriptome and interacts with a number of cellular proteins. In this study, we have attempted to explore the efffects of Vpr on human transcriptome and have identified several genes which are involved in innate immune respone and cell signaling pathways. We used the microarray analysis to elucidate the differnetail expression pattern of differnet genes in human macrophages infected with HIV-1 Vpr. As result we found that HIV-1 Vpr protein leads to the induction of various interferon stimualted genes (ISGs) and chemokines in human macrophages. Human monocytes-derived macrophages (MDMs) were isolated from peripheral blood mononuclear cells (PBMCs) from two healthy donors and were infected with recombinant adenoviruses either expressing HIV-1 Vpr or ZsGreen1 as a control. At 48 hours post-infection, RNA was isolated and subjected to microarray analysis.

IL-27 Inhibits HIV-1 Infection in Human Macrophages by Down-regulating Host Factor SPTBN1 during Monocyte to Macrophage Differentiation

Project description:The susceptibility of macrophages to HIV-1 infection is modulated during monocyte differentiation. IL-27 is an anti-HIV cytokine that also modulates monocyte activation. Here, we present new evidence that IL-27 promotes monocyte differentiation into macrophages that are non-permissive for HIV-1 infection. While IL-27 treatment does not affect expression of macrophage differentiation markers or macrophage biological functions, it confers HIV resistance by down-regulating spectrin beta non-erythrocyte 1 (SPTBN1), a required host factor for HIV-1 infection. IL-27 down-regulates SPTBN1 through a TAK-1-mediated MAPK signaling pathway. Knockdown of SPTBN1 strongly inhibits HIV-1 infection of macrophages; conversely, overexpression of SPTBN1 markedly increases HIV susceptibility of IL-27 treated macrophages. Moreover, we demonstrate that SPTBN1 associates with HIV-1 gag proteins. Collectively, our results underscore the ability of IL-27 to protect macrophages from HIV-1 infection by down-regulating SPTBN1, thus indicating that SPTBN1 is an important host target to reduce HIV-1 replication in one major element of the viral reservoir. 2 samples with different treatments were analyzed. Genes with absolute fold change >= 5 were selected.
