Differential expression of microRNAs in monocytes and derived macrophages in culture.

Project description:HIV-1 infection of monocytes/macrophages is modulated by several host factors. For instance, although HIV-1 successfully enters monocytes, antiviral restriction factors inhibit HIV-1 productive infection in these cells. We recently identified two microRNAs, miR-221 and miR-222, which limit HIV-1 entry during infection of monocyte-derived macrophages (MDM) by down-regulating CD4 expression. Interestingly, CD4 is also down regulated during the differentiation of monocytes into macrophages. In this study, we compared microRNA expression in monocytes and macrophages by RNAseq and found that miR-221/miR-222 are enhanced in macrophages.Taken together, these results show that both miR-221 and miR-222 act as modulators of CD4 mRNA expression throughout the monocyte/macrophage lineage, having roles in their differentiation, activation processes and modulating macrophage resistance to HIV-1.

Differential expression of microRNAs in productively HIV-1 infected and bystander macrophages in culture.

Project description:Macrophages are heterogeneous immune cells with distinct origins, phenotypes, functions and tissue localization. Their susceptibility to HIV-1 is subject to variations from permissiveness to resistance, owing in part to regulatory microRNAs. Here, we used RNAseq to examine the expression of >400 microRNAs in productively infected and bystander cells of HIV-1-exposed macrophage cultures. Two micro-RNAs up regulated in bystander macrophages, miR-221 and miR-222, were identified as negative regulators of CD4 expression and CD4-mediated HIV-1 entry. Both microRNAs were enhanced by TNF-α, an inhibitor of CD4 expression. MiR-221/miR-222 inhibitors recovered HIV-1 entry in TNF-α-treated macrophages by enhancing CD4 expression, and increased HIV-1 replication and spread in macrophages by countering TNF-α-enhanced miR-221/miR-222 expression in bystander cells. In line with these findings, HIV-1-resistant intestinal myeloid cells express higher levels of miR-221 than peripheral blood monocytes. Thus, miR-221/miR-222 act as effectors of the antiviral host response activated during macrophage infection that restrict HIV-1 entry.

Differential effect of glucocorticoids on the activation of monocytes and macrophages.

Project description:Glucocorticoids (GCs) reduce the expression of many genes induced in inflammatory conditions in vivo or by pro-inflammatory stimuli in vitro acting on the Glucocorticoid receptor (GR/NR3C1). However, GCs have pleiotropic effects on the immune system. Monocytes and macrophages are important cells of the innate immune system, exhibiting complex properties with enhancing as well as suppressive effects on inflammatory processes depending on their stage of activation and differentiation. Macrophages contribute to host defense, tissue remodeling and wound healing The mechanisms of GCs actions on monocytes and macrophages and their contribution to systemic anti-inflammatory effects remain unclear. These effects on activation GCs in monocytes and macrophages were investigated using the human monocytic cell line THP-1 and differentiation protocol PMA. Monocytes-THP1 and macrophages derived-monocytes were exposed for 6 hours to 100 nM of dexamethasone (Dex) and analyzed by microarrays. In macrophages-derived monocytes with respect to monocytes-THP-1, the number of genes differentially regulated was almost twice, among these, genes related with pro-inflammatory pathways, like TNFa, CXCL1 and GZMA. Interestingly, one of the genes differentially regulated (decreased) in macrophages exposed to Dex was the GR itself. If this effect modifies the inflammatory function of macrophages derived-monocyte is a question that will be evaluated through this study.

Expression analysis of dendritic cells, macrophages and monocytes

Project description:Expression profiles at different time points during dendritic cell differentiation (induced by specific culture conditions) including monocytes as well as expression profiles between monocytes and completely differentiated cells (macrophages at day7 and dendritic cells at day7, respectively) were compared. Monocyte-derived dendritic cells (DC) were obtained by culturing elutriated monocytes with 20U/ml IL-4, 280U/ml GM-CSF and 10% FCS; monocyte-derived macrophages (MAC) were obtained by culturing elutriated monocytes with 2% AB serum.

Differential effect of glucocorticoids on the activation of monocytes and macrophages

Project description:The Glucocorticoid receptor (GR/NR3C1) is expressed in almost all immune cells. Glucocorticoids (GCs) are potent regulators of inflammation with effects mainly immunosuppressive. While, GCs have pleiotropic effects on Macrophages exhibiting complex properties with enhancing as well as suppressive effects on inflammatory processes depending on their stage of differentiation and activation, the mechanisms of GCs actions on Monocytes and Macrophages and their contribution to systemic anti-inflammatory effects remain unclear. Previously we have demonstrated that NLRP3 expression is induced by GCs in macrophages differentiated from monocytes-THP-1 but not in monocytes. These findings raise the possibility that the stage of myeloid differentiation and the cellular environment dictates the actions of GR from a pro- or anti-inflammatory perspective. Moreover, our preliminary results using the same cell line THP-1 show that the differentiation process from monocytes to macrophages also is related with the downregulation of GR induced by dex.

Differential production of small RNAs in Mycobacterium tuberculosis infected primary human monocyte-derived macrophages

Project description:Primary human monocytes were isolated from four healthy donors. Monocytes were differentiated into macrophages, infected with virulent Mycobacterium tuberculosis (Mtb), strain H37Rv, for 24 or 48 hours, at a multiplicity of infection of 5 or 10. Following infection, infected cells and time-matched uninfected controls were harvested, total RNA including small RNAs was isolated and used for next-generation small RNA sequencing. Small RNA sequencing data was processed using miRge2.0, including a novel miRge2.0-based tRF detection tool. Processed data was used to determine differential expression of microRNAs and differential production of tRNA-derived fragments (tRFs) during infection with Mtb.
