Expression data of CD117+ splenocytes from C57BL/6 WT and RasGRP4 KO mice upon LPS stimulation

ABSTRACT: RasGRP4 is required for CD117+ DCs to optimally induce certain NK cell-dependent immune responses in vivo and in vitro in response to LPSRasGRP4 expressed in DCs played an important role on NK cell IFN-γ secretion . We used microarrays to detail the global programme of gene expression underlying cellularisation and identified distinct classes of up-regulated or down-regulated genes between the two DCs from WT and RasGRP4 mice respectively upon LPS stimulation.

KLRG1 and NKp46 discriminate subpopulations of human CD117+ CRTH2- ILCs biased toward ILC2 or ILC3

Project description:Recently, circulating multi- and uni-potential human ILC precursors (ILCP) have been found in a lymphocyte population that expresses CD117 and CD127 but lack CRTH2 and NKp44. However, these ILCPs have not been extensively characterized. We performed an unbiased Hierarchical Stochastic Neighbor Embedding (HSNE) analysis of the phenotype of peripheral blood CD117+ ILCPs which revealed the presence of three major subsets; the first expressed NKp46, the second expressed both NKp46 and CD56 and the third expressed KLRG1. Analysis of the differentiation potential of these cells on bulk and clonal levels, cytokine production and the transcriptome revealed that the NKp46+ ILCPs contain high frequencies of ILC3 precursors whereas a minority can differentiate into ILC1/NK-like cells. In contrast KLRG1+ ILCPs are biased to the ILC2 lineage, but are highly plastic and epigenetically poised to differentiate to other ILC subsets depending on the activation signals they receive.

Expression data from wt, Lkb1 conditional knock out and LPS treated DC

Project description:To dissect the molecular mechanism by which Lkb1 controls DC function, we performed transcriptional profiling of DCs sorted from Lkb1f/f, LPS-treated mice and Cd11cCreLkb1f/f mice. We used microarrays to detail the global programme of gene expression underlying cellularisation and identified

Expression data of quaternary clones from rat lung CD117+ endothelial cells vs. non-clonal control endothelial cells

Project description:One current concept suggests that unchecked proliferation of clonally selected precursors of endothelial cells contribute to severe pulmonary arterial hypertension (pAH). We hypothesized that clonally selected ECs expressing the progenitor marker CD117 promote severe occlusive pulmonary hypertension (PH). We used microarrays to identify the steady state gene expression profile of quaternary clones derived from CD117+ rat lung ECs vs control ECs derived from rat lung CD117- cells.

Expression profiles of mouse NK cell subsets

Project description:It is known that NK cells are a heterogeneous population of functionally distinct NK cell subsets. Here we report on different genomic, phenotypic and functional properties of four murine NK cell subsets distinguished by CD117 (c-kit), CD27 and CD11b expression. Gene expression was measured in NK cell subsets freshly sorted from murine C57Bl/6 splenocytes. Two to three different batches were analysed.

Microarray analysis of Zbtb46 KO CD4+ splenic DCs and bone marrow erythroid progenitors

Project description:Zbtb46 represses G-CSFR and LifR in cDCs Zbtb46 does not significantly affect gene expression in erythroid progenitors WT, Het, and KO cells were sorted from BM or spleen and analyzed. Pre MegE cells were sorted as CD117+ CD150+ CD105-CD41-CD16/32-. Pre CFU-E cells were sorted as CD117+ CD150+ CD105lo CD41- CD16/32-. CFU-E cells were sorted as CD117+ CD150- CD105+ Cd41- CD16/32-. Splenic CD4+ DCs were sorted as B220- CD11c+ MHCII+ CD8- CD172+ CD11b+ CD4+.

Human Innate Lymphoid Cell Precursors Express CD48 that Modulates ILC Differentiation through 2B4 Signaling

Project description:Innate lymphoid cells (ILCs) develop from common lymphoid progenitors (CLP), which further differentiate into the common ILC progenitor (CILP) that can give rise to both ILCs and NK cells. Murine ILC intermediates have recently been characterized, but the human counterparts and their developmental trajectories have not yet been identified, largely due to the lack of homologous surface receptors in both organisms. Here, we show that human CILPs (CD34+CD117+α4β7+Lin-) acquire CD48 and CD52, which define NK progenitors (NKPs) and innate lymphoid cell precursors (ILCPs). Two distinct NK cell subsets were generated in vitro from CD34+CD117+α4β7+Lin-CD48-CD52+ and CD34+CD117+α4β7+Lin-CD48+CD52+ NKPs, respectively. Independent of NKPs, ILCPs exist in the CD34+CD117+α4β7+Lin-CD48+CD52+ subset and give rise to ILC1s, ILC2s and NCR+ ILC3s, whereas CD34+CD117+α4β7+Lin-CD48+CD52- ILCPs give rise to a distinct subset of ILC3s that have lymphoid tissue inducer (LTi)-like properties. Additionally, CD48 expressing CD34+CD117+α4β7+Lin- precursors give rise to tissue-associated ILCs in vivo. We also observed that the interaction of 2B4 with CD48 induced differentiation of ILC2s, and together these findings show that expression of CD48 by human ILCPs modulates ILC differentiation.

Lin-CD117+CD34+FceRI+ progenitor cells are increased in chronic spontaneous urticaria and predict clinical responsiveness to anti-IgE therapy

Project description:Background: Chronic spontaneous urticaria (CSU) is a common, debilitating skin disorder characterised by recurring episodes of raised, itchy and sometimes painful wheals lasting longer than 6 weeks. CSU is mediated by mast cells which are absent from peripheral blood. However, lineage-CD34hiCD117int/hiFcεRI+ cells in blood have previously been shown to represent a mast cell precursor. Methods: We enumerated FcεRI-, FcεRI+ and FcεRIhi lineage-CD34+CD117+ cells using flow cytometry in blood of patients with CSU (n=55), including 12 patients receiving omalizumab and 43 not receiving omalizumab (n=43). Twenty-two control samples were studied. Disease control and patient response to omalizumab was evaluated using the Urticaria Control Test. We performed single cell RNA sequencing (scRNA-seq) on lineage-CD34hiCD117hi blood cells from a subset of patients with CSU (n=8) and healthy controls (n=4). Results: CSU patients had more Lineage-CD34+CD117+FcεRI+ blood cells than controls. Lineage-CD34+CD117+FcεRI+ cells were significantly higher in patients with CSU who had an objective clinical response to omalizumab when compared to patients who had poor disease control 90 days after initiation of omalizumab. scRNA-seq revealed that lineage-CD34+CD117+FcεRI+ cells contained both lymphoid and myeloid progenitor lineages, with omalizumab responsive patients having proportionally more myeloid progenitors. The myeloid progenitor lineage contained small numbers of true mast cell precursors along with more immature FcεRI- and FcεRI+ myeloid progenitors. Conclusion: Increased blood CD34+CD117+FcεRI+ cells may reflect enhanced bone marrow egress in the setting of CSU. High expression of these cells strongly predicts better clinical responses to the anti-IgE therapy, omalizumab.
