Transcriptional analysis of murine CXCR3+ vs. CXCR3- peritoneal cavity B cells 8 days following infection with Ehrlichia muris.

ABSTRACT: We performed bulk RNA sequencing on murine CXCR3+ and CXCR3-negative live singlet IgM+ IgD-neg CD19+ CD138-neg (B1 B cell-like) peritoneal cavity B cells to compare the transcriptomes of the two populations following i.p. infection with the intracellular bacterium Ehrlichia muris. Total RNA was extracted and sequenced, followed by pseudoalignment, quality assessment, normalization, and analysis of differential gene expression. The CXCR3+ B1 B cell-like population was highly enriched for genes involved in proliferation, metabolism, and cell division, whereas the CXCR3- B1 B cell-like population transcriptionally resembled canonical B1 B cells and did not appear to be proliferative. These results suggest local proliferation of CXCR3+ B cells occurs in the peritoneal cavity during acute infection with an intracellular bacterium.

Single cell RNA-seq and BCR-seq of peritoneal B cells

Project description:B1 cells account for the majority of B cell population in the peritoneal cavity, and are essential for the innate immune responses and maintaining the homeostasis. The origin of the B1 cells and how to form the B1 cells pool in the postnatal life remain unknown. And the heterogeneity of B1 cells can largely affect the functions of B1 cells. Until now, nobody has performed the single cell RNA-seq of peritoneal B cells. In order to reveal the characteristics of peritoneal B cells, we have performed the scRNA-seq and scBCR-seq of the peritoneal B cells of mouse from different stages.

Comparison of C57BL/6 and Dkk3-/- purified B1 and B2 cells

Project description:B2 cells were purified from spleen by CD19 Microbeads. B1 cells were purified from peritoneal cavity lavage by CD19 microbeads, followed by a depletion of CD23+ cells. RNA was prepared and differential gene expression analysis performed.

Ehrlichia chaffeensis TRP47 binding sites in human genome

Project description:Ehrlichia chaffeensis is an obligately intracellular bacterium that establishes infection in mononuclear phagocytes through largely undefined reprogramming strategies. Recently, E. chaffeensis effectors Ank200, TRP120, and TRP32 have been shown to function as nucleomodulins that enter the host nucleus and directly modulate transcription of genes implicated in cellular processes such as transcription regulation, apoptosis, phosphorylation, and immune cell activation. In this study, we found that E. chaffeensis TRP47 enters the host cell nucleus and binds regulatory regions of multiple host genes relevant to infection.

Pro-inflammatory Beta Cell Small Extracellular Vesicles Induce Beta Cell Failure Through Activation of the CXCL10/CXCR3 Axis in Diabetes

Project description:Coordinated communication among pancreatic islet cells is necessary for the maintenance of glucose homeostasis. In diabetes, chronic exposure to pro-inflammatory cytokines has been shown to perturb β-cell communication and function. Compelling evidence has implicated extracellular vesicles (EVs) in modulating physiological and pathological responses to β-cell stress. We report that pro-inflammatory β-cell small EVs (cytoEV) induce β-cell dysfunction, promote a pro-inflammatory islet transcriptome, and enhance recruitment of CD8+ T-cells and macrophages. Proteomic analysis of cytoEV revealed an enrichment of the chemokine, CXCL10, with surface topological analysis depicting CXCL10 as membrane-bound on cytoEV to facilitate direct binding to CXCR3 receptors on the surface of β-cells. CXCR3 receptor inhibition reduced CXCL10-cytoEV binding and attenuated β-cell dysfunction, inflammatory gene expression, and leukocyte recruitment to islets. Collectively, this work implicates the significant role of pro-inflammatory β-cell derived small EVs in modulating β-cell function, global gene expression, and antigen presentation through activation of the CXCL10/CXCR3 axis.

Human serous cavity macrophages and dendritic cells possess counterparts in the mouse with a distinct distribution between species

Project description:In mouse peritoneal and other serous cavities, the transcription factor Gata6 drives the identity of the major cavity resident population of macrophages, with a smaller subset of cavity-resident macrophages dependent on the transcription factor Irf4. Here we showed that GATA6+ macrophages in the human peritoneum were rare, regardless of age. Instead, more human peritoneal macrophages aligned with mouse CD206+ LYVE1+ cavity macrophages that represent a differentiation stage just preceding expression of Gata6. Low abundance of CD206+ macrophages was retained in C57BL/6J mice fed a high-fat diet or in wild-captured mice, suggesting that differences between serous cavity-resident macrophages in humans and mice were not environmental. Irf4-dependent mouse serous cavity macrophages aligned closely with human CD1c+CD14+CD64+ peritoneal cells that, in turn, resembled human peritoneal CD1c+CD14-CD64- cDC2. Thus, major populations of serous cavity-resident mononuclear phagocytes in humans and mice shared common features but the proportions of different macrophage differentiation stages greatly differ between the two species and DC2-like cells were especially prominent in humans.

Peritoneal cavity macrophage response to IFNg and IFNa

Project description:We seeked to determine in vivo effects of IFNg and IFNa response in peritoneal cavity macrophages. These cells were part of ImmGen Interferon cytokine study and immunocytes were sorted according to Immgen's standard lineage panel. Profiles from peritoneal cavity macrophages were used to analyze cell specific responses to IFNg.

T cell receptors repertoire sequencing of the human CD8+ naive subsets (CXCR3-,CXCR3+)

Project description:The presented data corresponds to the analysis of two discrete subsets of human CD8+ naive T cells, defined by positive and negative expression of the chemokine receptor CXCR3 (TNR3-, TNR3+). In this study we demonstrated that these subsets have different potential to generate fully-differentiated effector T cells following antigen-specific stimulation. The performed systematic immune repertoire analysis (T cell receptor beta chain (TRB)) of the sorted cell subsets revealed diverse physico-chemical properties of TRB CDR3 sequences suggesting enhanced TCR self-reactivity in human TNR3+ cells. In total, we analyzed 74 samples (from 11 patients, 3 replicates of each cell subset (excluding one missing replicate) and additionally for 3 patients CD8+ memory T cells in 3 replicates). We used the Human TCR Profiling Kit (MiLaboratory LLC) for sequencing libraries preparation and Illumina NextSeq 550 sequencing (150+150bp) followed by the demultiplexing procedure using MIGEC software (https://github.com/mikessh/migec).
