Difamilast treatment inhibits the expression of inflammatory mediators in bone marrow-derived basophils (BMBAs) stimulated by IL-3 + IL-33

Project description:In this study, we explored gene expression profiles of IL-3+IL-33-stimulated BMBAs treated with difamilast, a highly selective PDE4B inhibitor. We identified that difamilast-treated basophils showed downregulated expression of inflammaory mediators including Il4, Il6 and Il13.

Identification of novel activation marker and regulator of human basophils via transcriptomic analysis of IL-3-stimulated basophils

Project description:Human basophils regulate allergic immune responses by releasing histamine and effector cytokines such as interleukin 4 (IL-4) and IL-13. IL-3/IL-3R signaling axis plays key roles in the maturation, survival and activation of basophils. We and others have shown that IL-3-induced surface receptors e.g. ST2 and IL-17RB regulate the biology of basophils. We in this study aim to identify new basophil activation maker and regulator by transcriptomic analysis of IL-3-stimulated basophils.

Gene expression profiles of pre-basophils versus mature basophils stimulated with antigen/IgE- or IL-3-stimulation.

Project description:Basophils are the least common granulocytes which represent less than 1% of peripheral blood leukocytes. Recent development of analytical tools for basophils enables us to understand their critical roles in allergic reactions and protection from parasitic infections. Nevertheless, the differentiation trajectory of basophils remains unclear. We have identified previously-unappreciated pre-basophil subpopulation which encompasses previously-defined basophil precursors (BaPs) in a series of experiments including scRNA-seq analysis (deposited to GSE206589). In this study, we explored gene expression profiles of pre-basophils and mature basophils activated by antigen/IgE-stimulation or IL-3-stimulation. We have revealed that IL-3 activated pre-basophils displayed distinct gene expression profiles from antigen/IgE- or IL-3-stimulated mature basophils, suggesting the unuque property of pre-basophils.

Genome-wide analysis of mouse macrophages stimulated with IL-4 (bone marrow macrophages) (Affymetrix)

Project description:Analysis of alternative activation of macrophages at gene expression level. The study forms part of a wider study where we compare the effects of IL-4 in different human and mouse macrophages. Our results support the notion that in vitro culture conditions greatly affect the macrophage response to IL-4. Total RNA obtained from bone marrow derived macrophages upon exposure to 20 ng/ml of IL-4 for 18 hours. Bone marrow derived macrophages were stimulated with the Th2 cytokine IL-4, for RNA extraction and hybridization on Affymetrix microarrays.

Bone marrow-derived mast cells +- IL-33 48h

Project description:Mast cells are tissue resident granulocytes which are most abundant at the interface between tissues and the external environment, such as around blood vessels, in the skin or mucosal surfaces in the lungs and gut. Pathologically they are involved in allergic reactions and anaphylaxis, however they may also play protective roles in responses to some infections, particularly to pathogenic helminths. Mast cells also express high levels of the IL-33 receptor, which like TLRs, activates Myd88 dependent signalling pathways to drive de novo cytokine production in mast cells.IL-33 is a member of the IL-1 family known to stimulate a number of immune cell types including mast cells. IL-33 is a strong activator of de novo cytokine production in mast cells without inducing degranulation, although it has also been shown to synergise with other signals to promote degranulation. Bone Marrow-Derived Mast cells (BMMCs) were cultured as described previously [27]. Briefly, bone marrow was flushed in PBS and the cells pelleted by centrifugation. Cells were cultured at 1 million cells per ml in RPMI 1640 supplemented with 10% FBS (Biosera/Labtech), 5 mM l‐Glutamine (GIBCO Life Technologies), 100 U/ml Penicillin (GIBCO Life Technologies), 100 μg/ml Streptomycin (GIBCO Life Technologies), 25 mM HEPES (Lonza), 1 mM sodium pyruvate (Lonza), 1X nonessential amino acids (Lonza), 50 μM 2‐mercaptoethanol and 30 ng/ml IL‐3 (PeproTech). Cells were passaged twice per week and used between passage 12 and 16. 4 independent BMMC cultures were either stimulated with 10 ng/ml IL-33 for 48 hours or left unstimulated, followed by single shot LC-MS analysis.

Gene expression profiles of basophil progenitors, CD34- pre-basophils and mature basophils

Project description:In this study, we explored gene expression profiles of CD34-CLEC12Ahi pre-basophils isolated from the bone marrow as well as CD34-CLEC12Alo mature basophils from the bone marrow and CD34+ basophil progenitors. We revealed that the gene expression of mature basophils isolated from the bone marrow and spleen resembled each other whereas pre-basophils and mature basophils showed distinct gene expression profiles.

Transcriptional heterogeneity of mast cells and basophils upon activation. [basophils]

Project description:We performed large-scale comparative microarrays of bone marrow -derived mast cells and basophils at rest, upon an adaptive-type action (IgE-crosslinking) or upon innate-type activation (IL-33-activation).

Gene expression profiles of immature versus mature bone marrow-derived basophils (BMBAs) elicited by either IL-3 or TSLP.

Project description:In this study, we explored gene expression profiles of mature and immature basophils from either IL-3-elicited or TSLP-elicited BMBAs. We revealed that TSLP-elicited mature basophils displayed gene expression profile similar to that of IL-3-elicited mature rather than immature basophils.
