Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Severe asthma exacerbations in children requiring hospitalisation are typically associated with viral infection, and occur almost exclusively amongst atopics, but the significance of these comorbidities is unknown. We hypothesised that underlying interactions between immunoinflammatory pathways related to responses to aeroallergen and virus are involved, and that evidence of these interactions is detectable in circulating cells during exacerbations.
Publication Title
Interactions between innate antiviral and atopic immunoinflammatory pathways precipitate and sustain asthma exacerbations in children.

Description
Numerous microRNAs and their target mRNAs are co-expressed across diverse cell types. However, it is unknown whether they are regulated in a cellular context-independent or -dependent manner. Here, we explored transcriptome-wide targeting and gene regulation by miR-155, whose activation-induced expression plays important roles in innate and adaptive immunity. Through mapping of miR-155 targets using differential Argonaute iCLIP, mRNA quantification with RNA-Seq, and 3'UTR usage analysis using polyadenylation (polyA)-Seq in activated miR-155-sufficient and deficient macrophages, dendritic cells, T and B lymphocytes, we identified numerous targets differentially bound by miR-155. While alternative cleavage and polyadenylation (ApA) contributed to differential miR-155 binding to some transcripts, in a majority of cases identical 3'UTR isoforms were differentially regulated across cell types, suggesting ApA-independent and cellular context-dependent miR-155-mediated gene regulation reminiscent of sequence-specific transcription factors. Our study provides comprehensive maps of miR-155 regulatory RNA networks and offers a valuable resource for dissecting context-dependent and -independent miRNA-mediated gene regulation in key cell types of the adaptive and innate immune systems. Overall design: Primary dendritic cells, B cells, CD4 T cells, and macrophages from C57BL/6J wild type and miR-155 KO mice were cultured in RPMI medium with 10% FBS. Prior to harvesting primary dendritic cells, mice were subcutaneously injected with one million B16 melanoma cells expressing Flt3 ligand for about two weeks. After purification of splenic CD11c+ dendritic cells by CD11c microbeads (Miltenyi Biotec), dendritic cells were activated in a medium containing 100 ng/ml LPS (SIGMA) and 20 ng/ml GMSCF (Tonbo). Splenic primary B cells were purified by negative selection using Dynabeads Mouse CD43 (Invitrogen), and activated in a medium containing 25 ug/ml LPS and 6.5 ng/ml mIL4 (PeproTech). CD4 T cells from lymph node and spleen were purified with Dynabeads FlowComp Kit (Invitrogen). CD4+CD25-CD44- T cells were then activated with Dynabeads Mouse T-Activator CD3/CD28 (Invitrogen). Intraperitoneal macrophages, induced by thioglycollate injection, were harvested and activated with 100 ng/ml LPS.
