Expression profiling by high throughput sequencing

ABSTRACT: Innate immune cells control acute eosinophilic lung inflammation induced by cystein proteases. Here we characterize the dynamic change of gene expression profile in basophils, natural helper cells and eosinophils during lung inflammation via cystein protease Examination of mRNA levels in individual cell populations, basophils, natural helper cells and eosinophils of the lung from naïve mice and papain treated mice.

Immunity 20140501 5

Allergic asthma is an inflammatory disease characterized by lung eosinophilia controlled by type 2 cytokines. Cysteine proteases are potent triggers of allergic inflammation by causing barrier disruption in lung epithelial cells inducing the elevation of interleukin-5 (IL-5) and IL-13 from natural helper (NH) cells, a member of ILC2s, which leads to lung eosinophilia. In this study, we found that basophils play a crucial role in NH cell-mediated eosinophilic inflammation induced by protease alle ...[more]

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.

Microarray analysis on RNA from lung eosinophil subpopulation from naive or HDM-treated mice using Affymetrix Mouse Gene 2.0 ST

Project description:As opposed to their well-characterized contributions to inflammatory processes, tissue eosinophils are now also thought to contribute to immune homeostasis at mucosal sites such as the gut. Yet, whether such steady-state eosinophils exist in the lung is currently unclear. In this project, we identified and characterized lung resident eosinophil and also studied what happen to these cell during a mouse model of allergic inflammation (House dust mite (HDM) exact administrations). We compared the transcriptional profile of lung resident eosinophil from naive mice (rEOS ss) or from HDM-treated mice (rEOS i) and of inflammatory eosinophil (iEOS) from HDM-treated mice.

Human leukocyte expression profiles (in vitro)

Project description:CD34+ progenitor cells were cultured for 0 or 21 days in StemPro medium + supplement + IL-3 at 5 ng/ml Basophils, eosinophils and plasmacytoid dendritic cells were purified to near homogeneity and lysed for miRNA and mRNA. Basophils were purified by negative selection (StemSep Abs, miltenyi columns), eosinophils by StemSep Abs and pDC by positive selection after removing monocytes. The method starting with a 2-step Percoll gradient that put eosinophils in the pellet, basophils in the middle layer and pDC in the upper layer.

Lung Natural Helper cells

Project description:Natural Helper cells constitute a unique lineage of Th2-cytokine producting innate lymphocytes, here we characterize the gene expression profile of non-stimulated or PMA/ionomycin-stimulated Natural Helper cells from naive C57Bl/6 mouse lungs. We used microarrays to detail the gene expression profile of stimulated and unstimulated lung Natural Helper cells in mice. Lineage(-)Sca-1(+)c-Kit(-/low)CD127(+)CD25(+) Lung Natural Helper cells were purified from naive 6-8 week old B6 mice by FACS. RNA was extracted immediately from un-stimulated Natural Helper cells after FACS. Stimulated Natural Helper cells were cultured with PMA/ionomycin for 3 days followed by RNA extraction.

Eosinophils and basophils

Project description:Ten male 4get mice were infected with N. brasiliensis and single-cell suspensions of total lung tissue were prepared 9 days after infection. Cells were stained for CD3, CD19, c-kit and CCR3 and sorted for CD3-CD19-c-kit-GFP+CCR3+SSChi (eosinophils) and CD3-CD19-c-kit- GFP+CCR3-SSClo (basophils) using a MoFlo high-speed cell sorter (Cytomation, Fort Collins, CO). Total RNA was isolated from 2 x 106 eosinophils and 1.75 x 105 basophils using the Total RNA Isolation Kit (Fluka, Buchs, Switzerland) and amplified by two rounds of in vitro transcription using the Amino Allyl MessageAmpTM aRNA kit (Ambion, Austin, TX). Universal Mouse Reference RNA (#740100; Stratagene, La Jolla, CA) was amplified in the same way. Aminoallyl-UTP was incorporated during the second round of amplification and 5 µg of amplified RNA was coupled to Cy3 and Cy5 fluorescent dyes (CyScribeTM dye labeling kit, Amersham Biosciences, Peapack, NJ). Probes were hybridized to spotted glass oligonucleotide (70-mer) arrays which cover just over 16,400 unique genes (Mouse Genome Set Version 2.0, Qiagen, Germany). The arrays were prehybridized in 1% BSA (Invitrogen), 5 x SSC, 0.1% SDS for 2 hr at 42°C, washed in water and hybridized with the Cy3/Cy5-labeled probes in 2.8 x SSC, 0.2% SDS, 0.6 mg/ml Cot-1 DNA (Invitrogen), and 0.8 mg/ml yeast tRNA, at 63°C for 45 hr. Slides were washed sequentially in 0.03%SDS/1 x SSC, 0.2 x SSC and 0.05 x SSC, dried and scanned on an Axon 4000B scanner using Genepix 3.0 software (Axon Instruments, Inc.). Data were normalized using the R package Bioconductor software and ?lowess? normalization on the pixel medians without background subtraction (Ihaka and Gentleman, 1996).
