Project description:To infestigate the effect of macrophage on breast cancer cells, we treated breast cancer cells with medium from either monocyte derived macrophages or breast cancer cell medium treated monocyte derived macrophages
Project description:As supplies of monocytes, macrophages and dendritic cells from human sources can be scarce or prone to donor variation we established an efficient method to generate induced pluripotent stem cell derived monocytes that in turn could be differentiated into both macrophages and dendritic cells. We used RNA sequencing to profile these from multiple differentiation runs (n=3) and multiple monocyte harvests (n=3-4) and compared them to their blood derived counterparts, blood derived monocyte, monocyte derived macrophages and moncyte derived dendritic cells (from 3 donors).
Project description:The intestinal environment facilitates HIV-1 infection via mechanisms involving the gut-homing vitamin A-derived retinoic acid (RA), which transcriptionally reprograms CD4+ T cells for increased HIV-1 replication/outgrowth. Consistently, colon-infiltrating CD4+ T cells carry replication-competent viral reservoirs in people with HIV-1 (PWH) receiving antiretroviral therapy (ART). Intriguingly, integrative infection in colon macrophages, a pool replenished by monocytes, represents a rare event in ART-treated PWH, thus questioning the effect of RA on macrophages. Here, we demonstrate that RA enhances R5 but not X4 HIV-1 replication in monocyte-derived macrophages (MDMs). RNA sequencing, gene set variation analysis, and HIV interactor NCBI database interrogation reveal RA-mediated transcriptional reprogramming associated with metabolic/inflammatory processes and HIV-1 resistance/dependency factors. Functional validations uncover post-entry mechanisms of RA action including SAMHD1-modulated reverse transcription and CDK9/RNA polymerase II (RNAPII)-dependent transcription under the control of mammalian target of rapamycin (mTOR). These results support a model in which macrophages residing in the intestine of ART-untreated PWH contribute to viral replication/dissemination in an mTOR-sensitive manner.
Project description:To study monocyte and macrophage activation in ANCA-associtated vasculitis (AAV), we performed bulk RNA sequencing of bead-selected monocytes and in vitro cultured monocyte-derived macrophages from AAV patients and healthy controls. Overview patients included for sequencing monocytes: - AAV active disease, n=4, MPO-AAV=4 - AAV remission, n=10, PR3-AAV=5, MPO-AAV=5 - Healthy controls, n=6 Overview patients included for sequencing monocyte-derived macrophages: - AAV active, n=1, PR3-AAV=1 - AAV remission, n=3, PR3-AAV=3 - Healthy controls, n=3
Project description:To investigate the pro-inflammatory and metabolic function of Rheumatoid Arthritis monocyte derived macrophages RNA sequencing was perfomed on polarised healthy and Rheumatoid Arthritis monocyte-derived macrophages
Project description:Transcriptional profiling of M. avium subsp. paratuberculosis inside bovine monocyte-derived macrophages (MDMs; in vitro infection) during phagosome acidification at 30 min post-infection. M. avium subsp. paratuberculosis profiles from bafilomcyin A1 (acidification inhibitor) treated and untreated monocyte-derived macrophages were compared.
Project description:Transcriptional profiling of M. avium subsp. paratuberculosis inside bovine monocyte-derived macrophages (MDMs; in vitro infection) during phagosome acidification at 30 min post-infection. M. avium subsp. paratuberculosis profiles from bafilomcyin A1 (acidification inhibitor) treated and untreated monocyte-derived macrophages were compared. Two-condition experiment; 3 control (bafilomcyin treated) and 3 test, independently conducted. 1 control, 1 test per microarray.
