Project description:Murine monocytes (MC) are classified into Ly6Chigh and Ly6Clow MC. Ly6Chigh MC is the pro-inflammatory subset and the counterpart of human CD14++CD16+ intermediate MC which contributes to systemic and tissue inflammation in various metabolic disorders, including hyperhomocysteinemia (HHcy). This study aims to explore molecule signaling mediating MC subset differentiation in HHcy and control mice.Mouse white blood cell were prepared from peripheral blood and stained with antibody against CD11b, Ly6G and Ly6C and subjected for flow cytometry cell sorting. CD11b+Ly6G- cells were selected as MC. MC subsets (CD11b+Ly6G-Ly6Chigh, and CD11b+Ly6G-Ly6Clow) were sorted based on Ly6C levels. The quantification of MC was used flow cytometry analysis for Ly6Chigh and Ly6Clow MC in CT and Cbs-/-. Then, 100 ng mRNA were obtained from 100,000 sorted cells of CT and Cbs-/- (HHcy) mice. Around 30 million reads were achived and 16,487 normalized genes per sample by mRNA-Seq analysis.

Project description:Inflammatory monocyte (MC) subset differentiation is a major feature in tissue inflammatory and atherosclerosis. The underlying molecular mechanism remains unclear. This study aims to explore molecule targets and signaling which determinate immunological features in MC subsets. ApoE-/- mice were fed a normal chow diet and switched to a high-fat (HF) diet at age 8 weeks and maintained on a HF diet for 12-14 weeks. The control C57BL/6 mice were fed a normal chow diet throughout. Blood Ly6Chigh and Ly6Clow MC subsets from control and ApoE-/- mice were isolated by flow cytometry sorting and subjected for bulk high-throughput RNA-sequencing.

Project description:Currently, it is unclear if all monocyte subsets exhibit osteoclastogenic potential. Furthermore, the role of lineage determining TFs in regulating OC differentiation on a genome-wide scale remains poorly understood. In this study, we utilized a novel Irf8 conditional knockout (Irf8 cKO) mouse model to characterize the importance of IRF8 in OC progenitor development and epigenetic regulation of OC differentiation. To identify global transcriptional program governing the osteoclastogenic potential of Ly6Chi, Ly6Cint, and Ly6C– monocytes, and how it may be further influenced by IRF8 deficiency, we performed RNA-seq on sorted Ly6Chi, Ly6Cint, and Ly6C– cells from WT and Irf8 cKO mice. Cells were analyzed prior to (BMMs) and 4 days after RANKL stimulation (OCs). Here we show that WT Ly6Chi and Ly6Cint monocytes developmentally contain OC-specific transcripts, which are augmented upon RANKL stimulation. Additionally, in the absence of IRF8, OC-specific transcripts in all three monocyte subsets are primed to robustly respond to RANKL stimulation.

Project description:We performed a single-cell transcriptomic analysis of monocyte and monocyte progenitors by single-cell mRNA sequencing (scRNA-seq) using the C1 Fluidigm platform. We sorted BM cMoPs (Lin−CD117+CD115+CD135−Ly6C+), BM Ly6C+ monocytes (Lin−CD117-CD115+CD135−Ly6C+) and blood Ly6Chi monocytes (CD115+CD11b+Ly6Chi) from wild-type (WT) C57BL/6 mice by fluorescence-activated cell sorting (FACS) and generated transcriptional profiles for each individual cell (n = 38 for blood Ly6Chi monocytes, n = 66 for BM cMoPs, n = 57 for BM Ly6C+ monocytes).

Project description:Currently, the epigenetic mechanisms governing the osteoclast differentiation process remains poorly understood. To investigate the combinatorial activity of TFs, cis-regulatory elements, and the enhancer landscape that establish and maintain osteoclast transcriptional identity, we profiled histone modifications (H3K4me1, H3K4me3, H3K27ac, H3K27me3) and PU.1 and IRF8 binding by ChIP-seq. RNA-seq data from sorted Ly6Chi, Ly6Cint, and Ly6C– cells were overlaid with ChIP-seq data to identify epigenetic changes specific to each subset and genotype. Our data suggest that the Ly6Chi inflammatory monocytes and Ly6Cint cells are transcriptionally and epigenetically programmed to differentiate in mature osteoclasts when compared to Ly6C– anti-inflammatory monocytes. A combinatorial activity of TFs and cis-regulatory elements in the vicinity of several osteoclast-specific genes are responsible for establishing and maintaining osteoclast identity in these subsets. In Irf8 cKO mice, several promoters and enhancers established during the progenitor stage may be critical for initiating early lineage commitment and priming monocyte subsets to differentiate into robust osteoclasts.

Project description:Monocytes and their lineage descendants serve as a central defense system against infection and injury but if uncontrolled can also promote an excessive pathological inflammatory response. Therefore a current research goal is to understand how the organism controls the number and function of monocytes and how these variables can be tailored in therapy. Considering the evidence that monocytes are heterogeneous and exist in at least two subsets committed to divergent functions, we investigated whether distinct factors regulate the balance between monocyte subset responses in vivo. Here we investigate the differential expression of mRNA among murine steady-state monocyte subsets. Blood was drawn from healthy C57BL/6 donors. For each biological replicate 1000 monocytes of the Ly-6Chi and Ly-6Clo phenotype were isolated from the blood sample through fluorescence activated cell sorting.

Project description:Kawasaki disease (KD) is characterized by a disorder of immune response, and its etiology remains unknown. Monocyte is an important member of body's innate immune system, however its role in KD is still elusive due to its ambiguous heterogeneity and complex functions. Here, scRNA-seq was performed to reveal monocytes heterogeneity in healthy and KD infants. Circulating monocytes were separated from peripheral blood and scRNA-seq was used to transcriptionally profile the monocytes in both healthy and KD infants. Four monocyte subsets are identified in infants, in which three clusters are mainly CD14+CD16- monocytes and one cluster is mainly CD14-CD16+ monocytes. The four monocyte subsets possess different biological functions and represent a relatively linear differentiation. CD14+ monocyte subsets in KD are distinct from that of healthy infants, including one subset expressing FOLR3, S100A12 and IL1R2 and the other expressing MT-TN specifically. Moreover, the CD14+ monocyte subsets in KD are poorly differentiated, and their functions mainly involve neutrophil activation. In conclusion, a relatively comprehensive map of circulating monocyte subsets was plotted for the first time in healthy infants. CD14+ monocyte subsets that are distinct from healthy infants were revealed in KD, which may serve as a target for KD treatment in the future.
