Transcriptomic profile of Sialyl-Lewis X (CD15s)+ basophils and Sialyl Lewis X- basophils

Project description:Sialyl Lewis X (sLexX or CD15s) is a tetra-saccharide N-acetylneuraminic acid, galactose, fucose and N-acetylglucosamine (NeuAcα2,3Galβ1,4(Fucα1,3)-GlcNAc). CD15s is present on various leukocytes usually as O-linked glycans bound to surface molecules such as PSGL-1, CD43 and CD44. On leukocytes, CD15s plays crucial role in extravasation through the interaction with E-selection expressed ion surface of the activated epithelial blood vessels. We find in approximately 10% of individuals basophils lack CD15s on their surface and these basophils fail to roll on E-selectin coated surfaces. In humans, six α(1,3)-fucosyltransferases (FT), α(1,3)-FTs: FT3/FT4/FT5/FT6/FT7/FT9) catalyses the transfer of fucose to the terminal lactosaminyl glycans giving rise to Lewis X (CD15) and/or sialyl Lewis X (CD15s). To identify which enzyme(s), we perform RNA-sequencing of CD15shigh(CD15s Pos) and CD15slow (CD15s Neg) basophils from 6 individuals.

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.

Cebpa regulates gene transcription in basophils

Project description:To investigate the mechanisms by which C/EBPa drives basophil differentiation and maintains basophil identity, we examined whether or not C/EBPa promotes basophil molecular programming and simultaneously represses mast cell molecular programming. We performed genome-wide gene expression profiling on basophils and mast cells and found that 6798 genes were shared by mast cells and basophils; 2033 genes were expressed 2-10 (log2 1-3.3)-fold higher in basophils (differentially expressed in basophils); and 413 genes were expressed greater than 10 (log2 3.3)-fold in basophils (highly expressed in basophils). On the other hand, we found 569 genes were expressed 2-10 (log2 -1 to -3.3) fold higher in mast cells and 171 genes were highly expressed in mast cells [greater than 10 fold (log2 -3.3)]. We treated purified basophils prepared from Cebpaf/f RosaYFP/creER mice and Cebpa+/+ RosaYFP/creER control mice with or without 4HT treatment for five days. Gene expression in the treated basophils was analyzed using microarray analysis. Overall, deletion of C/EBPa in basophils resulted in a reduction of mRNA expression for 248 genes and led to an increase in mRNA expression for 255 genes. The majority of the C/EBPa-regulated genes were either differentially or highly expressed in basophils or mast cells. In this study, we compared gene expression in basophils and mast cell and identified genes which specifically expressed in basophils and mast cells. By using Cebpa conditional knock out mice, we identified Cebpa regulated genes in basophils.

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.

Transcriptomic computational analysis of mastic oil-treated Lewis lung carcinomas

Project description:Mastic oil from Pistacia lentiscus variation chia, a blend of bioactive terpenes with recognized medicinal properties, has been recently shown to exert anti-tumor activity. Lewis lung carcinoma (LLC) cells are mastic oil-susceptible cells and were used in this work to study the effects of mastic oil at the transcriptomic level.

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.

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.
