Butyrate-induced LncRNA lncly6c promotes Ly6Chigh to Ly6Clow/neg macrophages through lncly6c /C/EBP/Nr4A-1 axis

Project description:Gut macrophages play a critical role in maintaining the homeostasis of gut immunes. The inflammatory macrophages generally are differentiated into resident macrophages to realize their function in gut tissues. But it is unclear how these inflammatory macrophages to differentiate resident macrophages. We here found that lycLy6c, a novel ultraconserved lncRNA, may promote the differentiation of gut inflammatory macrophage into gut resident macrophages. We demonstrate gut microbiota metabolites butyrate may upregulate the expression of lncly6c. Lncly6c not only binds with transcription factor C/EBPβ but also binds with multiple components of enzyme complexes, which promote the accumulation of H3K4me3 markers on the promoter region of NrA4-1. As a result, lncly6c causes the upregulation of Nr4A-1 to promote inflammatory macrophage to differentiate the resident macrophages. These results not only offer an evidence for gut microbiota to maintaining the gut homeostasis but also suggest a potential target for the therapy for colitis-associated diseases.

Triggering of NOD2 receptor converts inflammatory Ly6Chigh into Ly6Clow monocytes with patrolling properties.

Project description:In the present study, we demonstrate that NOD2 receptor triggering by muramyl dipeptide converts blood inflammatory Ly6Chigh monocytes into patrolling Ly6Clow monocytes. Muramyl dipeptide administration to Nr4a1-/- mice, which lack Ly6Clow monocytes, and to Ly6Clow-depleted mice leads to the emergence of blood patrolling monocytes expressing phenotypic profile of typical Ly6Clow monocytes, including high expression of CX3CR1 and LFA1. Furthermore using intravital microscopy in live animal models of inflammatory diseases, we observed that converted Ly6Chigh monocytes are capable of patrolling the endothelium of blood vessels and their presence contributes to reduce the inflammatory response following muramyl dipeptide injection.

Dynamic lipid mediator changes support infiltrating macrophage subtype transitions during skeletal muscle injury and regeneration

Project description:Time-dependent profiles were recapitulated in sorted neutrophils and Ly6Chigh and Ly6Clow muscle macrophages, with a distinct pro-resolving signature observed in Ly6Clow reparative macrophages. RNA-seq analysis of macrophages stimulated with resolvin D2 (RvD2) showed similarities to transcriptional changes found during the temporal Ly6Chigh to Ly6Clow phenotypic transition. Importantly, RvD2 promoted the temporal progression from Ly6Chigh to Ly6Clow macrophages in vivo.

Single-cell RNA seq reveals the transcriptional landscape and heterogeneity of macrophages in murine gut tissues

Project description:CD11b+ cell populations, especially macrophages are highly heterogeneous tissue resident immune cells in both mice and human. Exact subsets and their phenotype remain unknown. We here analyzed gut CD11b+ cell populations using scRNA-seq in normal, inflamed and Nlrc4 deficient mice. There existed twelve CD11b+ cell populations and subsets in SPF mice. These CD11b+ subsets were changeable dependent on inflammation and gut environment. We found consistent high expression of Ly6C, Cd62L, previously undescribed Trem1 and Ccr7 in Ly6Chigh macrophages and Cd206 and Cx3cr1 in Ly6Clow/neg cell population in different mice. However, signature genes showed that resident macrophages but not inflammatory macrophages were highly conserved in normal and inflamed mice. Gut microbiota play a role in accumulation and differentiation of gut macrophages. Both Ly6Chigh and Ly6Clow macrophages in intestine and colon tissues are similar. These uncover the transcriptional landscape and phenotypic heterogeneity of CD11b+ cells, especially macrophages in gut tissues.

Identification of miR-146a target genes in mouse monocyte subsets

Project description:To gain insight into the mechanisms underlying miR-146a-mediated modulation of Ly6Chigh monocyte function, we compared the expression profiles of Ly6Chigh and Ly6Clow monocytes in miR-146a+/+ (WT) versus miR-146a-/- (KO) conditions.

Ly6C monocyte subsets transcriptome analysis from wild type and hyperhomocysteinemic mice

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.

Gene expression profiles of wild type and Nr4a-triple knockout (Nr4a-TKO) Tnaive and iTreg 3 h

Project description:In this study, we investigated the roles of Nr4a family transcription factors in Th and Treg cell differentiation from Tnaive cells. Nr4a factors were found to promote Treg cell differentiation and repress Th1 and Th2 differentiation. During Treg cell differentiation, all Nr4a factors are transiently induced in Tnaive cells immediately after TCR stimulation, whereby they mediate epigenetic changes directly or by cooperating with other transcription factors. To reveal Nr4a factors' mediated transcrptional events, we analyzed gene expression of wild type and Nr4a-tripple knockout (Nr4a-TKO) Tnaive and iTreg cells by microarray analysis.
