Analysis of monocytes treated with an NF-kappaB or a phosphatidylinositol 3-kinase (PI3K) inhibitor and then infected with the human cytomegalovirus (HCMV). Results provide insight into the role of NF-kappaB and PI3K in the activation of monocytes to a proinflammatory state after an HCMV infection.

(Submitter supplied) Human cytomegalovirus induces a pro-inflammatory monocyte following infection and we have evidence that NF-κB and phosphatidylinositol 3-kinase [PI(3)K] are key mediators in this early activation. To begin to address how these signalling pathways are responsible for the rapid activation of infected monocytes, we examined the role these pathways played in the transcriptome of infected monocytes. Global transcriptional profiling using cDNA microarrays revealed a significant number of genes, including inflammatory genes, were regulated in a NF-κB- and/or PI(3)K-dependent manner, identifying these pathways as key cellular control points in the conversion of monocytes to an activated pro-inflammatory state following HCMV infection. more...

(Submitter supplied) We have established that human cytomegalovirus (HCMV) infection modulates the biology of target primary blood monocytes, allowing HCMV to use monocytes as “vehicles” for its systemic spread. HCMV infection of monocytes results in rapid induction of PI(3)K and NF-κB activity. Integrins, which are upstream of the PI(3)K and NF-κB pathways, were shown to be involved in HCMV binding to and entry into fibroblasts, suggesting that receptor-ligand-mediated signaling following viral binding to integrins on monocytes could trigger the functional changes seen in infected monocytes. more...

(Submitter supplied) Human cytomegalovirus induces a pro-inflammatory monocyte following infection. To begin to address how HCMV induces these rapid changes in infected monocytes, we examined the transcriptome of infected monocytes. Global transcriptional profiling using cDNA microarrays revealed a significant number of pro-inflammatory genes were upregulated within 4 hours post infection. Keywords: Disease State

(Submitter supplied) We employed RNA-seq to map the transcriptome of human MRC5 fibroblasts during HCMV infection with AD169 and AD169-ΔUL26 strains. These data will highlight the ways in which the HCMV UL26 protein alters host gene transcripton during infection.

(Submitter supplied) Continuous PI 3-kinase signaling is required for cell proliferation and survival, but the gene expression program controlled by PI 3-kinase in proliferating cells has not been elucidated. We used microarray analyses to characterize the changes in gene expression resulting from inhibition of PI 3-kinase in actively proliferating cells. Following 2 and 4 hours of PI 3-kinase inhibition, the time around which apoptosis initiated, 32 genes were significantly up-regulated and 53 down-regulated. more...
