Basophils prime group 2 innate lymphoid cells for neuropeptide-mediated inhibition [RNA-seq]

Project description:Type 2 cytokine responses promote parasitic immunity and initiate tissue repair but, can also result in immunopathologies when not properly restricted. Basophilia is recognized as a common feature of type 2 inflammation, however, the roles basophils play in regulating these responses remain unknown. Here, we demonstrate that helminth-induced ILC2 responses are exaggerated in the absence of basophils, resulting in increased inflammation and diminished lung function. Additionally, we show that ILC2s from basophil-depleted mice express reduced levels of the receptor for the neuropeptide, neuromedin B (NMB). Critically, NMB stimulation inhibited ILC2 responses from control but not basophil-depleted mice, and basophils were sufficient to directly enhance NMB receptor (NMBR) expression on ILC2s. These studies suggest that basophils prime ILC2s to respond to neuron-derived signals necessary to maintain tissue integrity. Further, these data provide mechanistic insight into the functions of basophils and identify NMB as a potent inhibitor of type 2 inflammation.

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 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.
