Project description:STAT5 functions in human inflammatory monocytes is largely unknown. We identified the anti-inflammatory function of CD127-STAT5 axis in human monocytes. To investigate the mechanism underlying STAT5-mediated anti-inflammatory regulation, thoroughly dissecting the STAT5 genomic distribution in human monocytes would be informative. Therefore, we performed anti-STAT5 ChIP-seq analyses for CD127high monocytes under LPS stimulation to globally characterize the STAT5 occupancy in CD127 expressing human monocytes.
Project description:The heterogeneous characteristics of activated monocytes are much unknown. We performed the single cell transcriptomic analysis of LPS-treated human monocytes from healthy blood donor, and CD127 expression associated expression pattern of inflammatory genes was identified in LPS-treated monocytes.
Project description:We performed the transcriptomic and epigenetic analysis for both CD127high and CD127low monocytes under LPS stimulation, and RNA-seq and ATAC-seq were performed accordingly for this purpose.
Project description:CD14+ Monocytes from healthy volunteers were purified by MACS (negative selection) and FACSorting and either left untreated or stimulated for 24h and 48h with LPS. THP-1 cells were stimulated for 4h, 24h and 48h with LPS. Glycoproteins were captured with hydrazide chemistry and tryptic and PNGase F-released peptide fractions analyzed by MS/MS. Quantitative assessment revealed differential glycoprotein expression in activated/LPS-tolerized monocytes and naïve monocytes and THP-1 cells.
Project description:The essential role of interleukin 7 (IL-7) signaling via its receptor (IL-7Rα; CD127) in T cell development and function has been well documented. However, CD127 expression and function in myeloid cells, including monocytes, are less clear, especially in mice. In the present study we report an inducible CD127 expression in mouse monocytes/macrophages. This induction is dependent on the presence of other immune cells, highlighting that regulation of CD127 expression on monocytes differs in mice and humans. We demonstrate that CD127 is functional, as IL-7 downregulated its expression. We also saw decreased CD127 expression during inflammation in vivo. Overall, upregulation of CD127 expression in vitro and its downregulation in vivo confirm that CD127 is an inducible marker on mouse monocyte/macrophage cells, in contrast to findings recently published by others. Characterizing the role of CD127 signaling in myeloid cells in inflammatory disorders would be worthwhile in future study.
Project description:To investigate the possible therapeutic effects of ibuprofen and Pep19-2.5 alone or in combination on the LPS-response of human monocytes. Human monocytes were challenged with 0.1ng/ml LPS and/or 10ng/ml Pep19-2.5 LPS. Medium controls served as unstimulated samples. LPS and Pep19-2.5 was used either alone or together to LPS-challenged samples. RNA was extracted after 4 hrs of stimulation. Three biological replicates were conducted
Project description:To screen the genes and pathways regulated by BRD3 in the THP1 monocytes induced by LPS, THP1 monocytes were transfected by BRD3shRNA and then treated by LPS for 3 hours.
Project description:To screen the genes and pathways regulated by CREB1 in the THP1 monocytes induced by LPS, THP1 monocytes were transfected by CREB1 shRNA and then treated by LPS for 3 hours.
